alpha_max 200 # this gets loaded after homing when home_to_max is set I am using a regular limit switch with NC going to the signal pin and the other to ground. I feel that the machine has a nebulous idea of where the machine is at. I currently don’t have the LCD, could this be preventing it from working? I am having problems with my Y endstops from working . you need to ether remove the resistor, which is really hard or asign another pin to the Z endstop and put the signal cable of your probe to this pin. I’m using a Ramps 1.4 board with the Marlin-MPCNC_Ramps_T8_16T_LCD_32step_DualEndstop firmware. If you don’t find them to be don’t hesitate to ask further questions. it will only lead people to feel fooled once those kind of troubles are discovered. gamma_limit_enable false # set to true to enable Z min and max limit switches. I have even shorted the signal and ground pins on the Ramps board with a jumper wire and I still haven't seen any change. Also check for continuity again, using a multimeter. it is simple => a 3d printer behaviour (not cnc) => on any axis, when you hit an endstop in min you can not go any further backwards, but you can still operate and go forwards. Thanks for contributing an answer to 3D Printing Stack Exchange! Bed Leveling is a standard feature on many 3D printers. Connect to your printer from host software such as Cura, Printrun or Repetier Host. If I would have homed the Z axis instead of clicking it many times it would have stopped my machine? Are Random Forests good at detecting interaction terms? All of my attempts to contact any support have ended up with nonsensical responses in broken English that did not address the issue I am having. I home it and it finds a corner… then in the config file I say it is 200mm from the home position. Marlin has the dual endstops. It’s something that is being actively worked on. Or I can enable limit switches which pause the machine… sure it paused which is good but the machine is useless at this point until I turn everything off and back on. I used the 2.00 pin on the SKR 1.3 and im going to use the 0.10 pin on the SKR 1.4. The post copied below says the end stops only work for homing. (though I really want it to work on my i3 prusa homemade clone). ... move X/Y/Z to min endstops\nG29 ;auto level"\n. Plugging them in in the max endstops does show change when they are pressed with M119. That’s just a guess. By reading the documentation, we can deduce that software end-stops are not implemented (by soft end-stops, I mean what any other 3d printer architecture means : limiting max distances), BUT, hardware end-stops (limiting movement by hardware eg. The thing is : it’s much more difficult to implement than it seems ( or it’d be in already ). optional order in which axis will home, default is they all home at the same time, if this is set it will force each axis to home one at a time in the specified order, optional enable limit switches, actions will stop if any enabled limit switch is triggered.

The unused extruder driver/s are used for the extra stepper/s. I have edited the config and tried with and with out the ! I have an old Solidoodle 2 that I bought broken from a garage sale that I am converting to use RAMPS 1.4 with Marlin Firmware. What would you expect on a mill or a fdm printer to do for a move that goes outside of the workspace? My config can be found here: pastebin.com / zJZ4SLBx, endstops_enable true # the endstop module is enabled by default and can be disabled here If they are optical endstops, first make sure that you have S1 in the M574 command. I have tested that my endstops function by sending M119 and verifying that the endstops correctly show OPEN or … Issue the command M111 S247 to enable maximum logging. gamma_max_endstop nc # Having my beta-endstop at the max position of my Y-axis I would love to see the bed moving to its logical origin. Is the line uncommented ? 1.1.7 debug HAS_TRINAMIC_CONFIG ... sdcard HAS_SPI_FLASH SDSUPPORT MARLIN_DEV_MODE M993-M994 - SD / SPI Flash. The hard endstop result in a halt state yes, which then requires M999 to get out of. halting the entire printer is not what I want : I just want the axis to stop at hardware endstop and do not go further on the endstop direction if triggered … gamma_min_endstop 1.28^ # gamma_max 200 #, #homing_order XYZ # x axis followed by y then z last, alpha_limit_enable false # set to true to enable X min and max limit switches beta_min_endstop nc # "it is possible that the endstop pin on the Atmel chip is not working anymore. I have had my 5x board for a while now because everything can make it blow up and I didn’t feel there is enough information to get it right. rev 2021.1.8.38287, The best answers are voted up and rise to the top, 3D Printing Stack Exchange works best with JavaScript enabled, Start here for a quick overview of the site, Detailed answers to any questions you might have, Discuss the workings and policies of this site, Learn more about Stack Overflow the company, Learn more about hiring developers or posting ads with us. If you have any endstops not behaving you turn off the printer, unplug the USB and Check the pin-connection.Correct as nesccesary. I have searched and read lots of posts but nothing fixed the issue. My endstop configuration is currently: I have X-min enabled and inverted. Marlin has support for four temperature sensors (three extruders, one heated bed). All primary/basic features are already handled by 8bit arch 3d printer controllers, I was search for some new features and enhancements (SD card config, network, speed …), but not in sacrifice of primary/basics ones. How can a non-US resident best follow US politics in a balanced well reported manner? com / watch?v=r8IndlYyA_0 (remove spaces). Since this project is not new (smoothie is around for about 4/5 years now), why is it not simply stated like this on the documentation ? … worse for max_endstops : even triggered, it tries to go further, hitting the max_endstop does NOT even stop the movement, and does NOT protect the printer. TO further test, I tried ALL of the motor axis and they all move when holding the same endstop, so its not just that I have them crossed. All 4 files are also in the attached Base config (Z-endstop only, no BLTouch, homing at X=0, Y=0).zip file, the configuration in them matches the config in Option 1. Software end-stops are enabled by default. alpha_homing_direction home_to_min # or set to home_to_max and set alpha_max BUt Y does not . alpha_min_endstop 1.24^ # add a ! try uncommenting the following lines to enable endstop detection on all pins for troubleshooting. beta_min 0 # If yes, why is it not simply and clearly written like that on the documentations ? UPDATE: HURRAY !!! If I am wrong then the machine tries to make it to 200mm by brute force! I have took a look to the limit_enable thing => it is clearly too drastic ! Here is the boilerplate: Download Marlin bugfix-2.0.x to test with the latest code. It only takes a minute to sign up. beta_limit_enable false # set to true to enable Y min and max limit switches Same problem here for me as @Dytoractor, I have 6 Normally Open (NO) endstops (one at min and max of each axis), configured with “!” in order to be inverted. Will it burn up the driver if I connect both motors to the same driver? If I enable the 3 “limit switches” lines, the printer does stop when the switch is hit, but then I have to reset. For other boards you may need to define FIL_RUNOUT_PIN. -Not very good for a kill switch really. Then the machine is able to ignore moves that would go out of the machine area. This is sad… and dangerous for the mechanical integrity of a machine… This should be implemented asap!!! I don’t know anything about carbide motion but if it’s grbl compatible, it probably won’t work for Marlin. This was without ANY USB plugged in and using the touch screen to move. Hi, I have been scouring the internet for weeks trying to get my Arduino Due + RADDS 1.5 + PanelDue set up for my Kossel printer. control M121 - Disable Endstops. I have this switch plugged into first header column for X-min. So “universal” way is to put in an optocoupler which is not only working but protects your board from damaging Sensor support. It’s me again, was away for a long time … my projects were on stanby for some problems I had … When I send an M119 (endstop status code) I recieve: And then when I press down the X endstop with my hand I get: -No change. Apparently it is a bug for MAC but i am using WIndows 8.1. The console got the commands and and it looks like it should have moved. I need the endstops for homing AND to let the board know when it has reached the start of the axis, and that the other end is 200 mm in the other direction(software endstop). The other question I have is how to use the E1 driver to drive my second Z motor on my Prusa i3. Please can someone confirm : to resume, on smoothieware, hardware endstops only work for homing action, or as a kill switch. Si je puis me permettre d’après votre fichier config vous n’avez pas de butées beta mini donc pour la prise d’origine je pense que cela doit poser un problème pour le réference de vos déplacements, je dis peut être une co…….! when i try to auto home my printer via LCD or in the software it seems that it totally ignores the endstops of the x+z axis. All the motors work correctly, I am just having issues getting the endstops to work. You’ve been very agressive towards people who are giving you their free time as a present, I can’t understand it, and I think you need to read : http://smoothieware.org/troubleshooting#i-m-very-upset-at-something-everyone-is-mean-and-nobody-listens-to-me, Powered by Discourse, best viewed with JavaScript enabled, https://docs.google.com/document/d/1U6nzx1boqF-J2GGPWF4yIaaVib0JNodVWSKBfwiyp_M/edit, http://smoothieware.org/troubleshooting#i-m-very-upset-at-something-everyone-is-mean-and-nobody-listens-to-me. I wanted to get a status on the progress in the area of the endstop functionality. In reading posts on the forum about endstops, it looks like endstops on Smoothie may not work the way I expect them too. You can have “hitting end of axes causes the movement to be ignored”, which is what you asked for ( correct me if I misunderstood ). Endstops are used only for homing, and for limit switches, at the moment. Use MathJax to format equations. If the status does not change when activated it is most likely due to bad pin-wiring on Ramps, but it can also be the firmware. That means the z endstop pin doesnt work. Im using CNCjs and it seems to connect fine but when I go to move it though the GUI it doesn’t move. Thanks for replying, but, like I already said on my last message : “I have took a look to the limit_enable thing => it is clearly too drastic ! beta_max_endstop 1.27^ # As supplied, the endstops are only configured as home switches, in effect, once triggered, you can manually step, or drive the head past them. This command can be used to enable one or more steppers (X,Y,Z,E). Printer area. a logical comparison agains a stored min and max value (set on homing) which prevents the machine over- and under-running its axis dimensions? youtube . This issue cannot be closed. #define min_software_endstops true. As said before, I need the endstops for homing AND to let the board know when it has reached the start of the axis, and that the other end is 200 mm in the other direction without coming to a full stop because the end stop was hit. I am using a regular limit switch with NC going to the signal pin and the other to ground. When I home (in Pronterface Here) in the Y direction its as if the endstop is not even connected no response form the switch. Asking for help, clarification, or responding to other answers. You can set the value of the parameter to 0 (not used), 1 (RRW thermistor 100K) or -1 (RRW thermo couple). The way this is done is by homing the machine so it knows where it is. He wants the machine to ignore any command that would take it outside the work area, which Smoothie can do. I've attached a copy of my Marlin configuration.h file. I just set up a MKS SBase 1.2 I have everything figured except for two things. The travel distance is not calibrated yet and the practical distance will be different than the calculated distance. In Pronterface I couldn’t find a stop machine from killing itself button. http://smoothieware.org/endstops#limit-switches. It turned out to be a combination of those lines being commented out and the end stops were connected to the wrong two pins. The only thing I can think of is that either the switch is plugged into the wrong pin on the ramps board (Max instead of Min) or the switch doesn't require the pullup (your could try commenting that back as a second test as well). I have everything assembled and wired up. If you enable an axis with limit switches, you also need to ensure that the axis-minimum is set to NC to avoid a false trigger of the limit as the carriage is backed off the switch. I worked on number of big professional cnc machines and when you issue a move that goes outside of the workspace every single one of them will halt and turn on the warning light?! Thanks! Thanks a lot. If I get this figured out, I am going to buy a board from you guys to put in my k40 laser. I have an old Solidoodle 2 that I bought broken from a garage sale that I am converting to use RAMPS 1.4 with Marlin Firmware. Printer moves korrekt, but even software endstops won't work. To subscribe to this RSS feed, copy and paste this URL into your RSS reader. So to make it clear: Smoothieware does not support software endstops aka. can you help me… i suppose is in marlin but i can’t find the problem. I've tried changing home position. A caveat, you can resume the program (play), however the carriage that triggered the limit, will continue on through the limit switch, also, all endstops will be disabled at this point, until the printer is reset. About drivers. If the seller is unable to help you, feel free to ask again here. I have everything but two What you can do is to use the MAX endstop pins for the X endstop by defining the X endstop using the pin of the MAX endstop. May be there is an explanation for this behaviour, I would be glad to know it, could someone explain that ? I’ll download the latest edge firmware and configure the soft endstops as documented ^^ !! Unfortunately, the method I proposed above does not work. What are the earliest inventions to store and release energy (e.g. load or back up SPI Flash and SD. No dishonesty there, just a lot of hard volunteer work. To test, I have pressed one of the endstops with a finger and have … Well I’m sorry I do my best to make my answers complete and straight. Is this true? Solved I found the way the limit switches are implemented (machine full stop) to be overly dramatic for my use case. First atomic-powered transportation in science fiction and the details? A second issue I have, is that after homing (which works fine) the config flag “move_to_origin_after_home” is ignored / not executed. Anyway, I’m trying to get it working again, and since you say that it works (“which Smoothie can do.”), I would be glad to know what I need to enable/activate to do so. How to calculate charge analysis for a molecule, Don't understand the current direction in a flyback diode circuit. If you where to cut out that part it would result in going negative past your endstops and misalign your machine. Connecting Sain Smart Mechanical End Stops to Ramps 1.4? Obviously there are many people with problems using TMC2209 with sensorless homing. I'm frustrated. Initial script (GCODE commands) Hello all. bon courage, has there been a solution to this i have same problem I think I had the wrong idea of what an endstop did as well. If they never show as triggered, check that the flag on the end of the axis blocks the slot completely, and that there is a pullup resistor between the sensor … EDIT: It takes the guess-work out of getting a good first layer and good bed adhesion. I've checked M119 and all three of the endstops show to be triggered when manually pushed. Enable endstops and keep them enabled when not homing. If the filament runs out, Marlin will run the specified G-code script (by default M600). It might, but the motion feedback in grbl is totally different. ", This, is clearly too drastic, so useless in my case …. Here we can tell the firmware what the limits are of the travel zones. #define min_software_endstops false #define max_software_endstops false. I’ve chosen this solution for building my first 32bit printer because of the features it has, BUT, if I knew that from the beginning, I may not have done that choice. I clicked the z-axis movement in Pronterface many times to get it to the endstop and my machine runs the y axis into the bed nonstop until it ripped the couplings off the z motors. Homing functions works correctly, BUT, after homed (all home_to_min, so min_endstops are triggered), if I ask the printer to go further backwards … it tries to go further even with the endstop triggerred (which, for me, is a complete NONSENSE! ) What sort of work environment would require both an electronic engineer and an anthropologist? The offset in X,Y, and Z are the values defined in the firmware (In Marlin Configuration.h). I did end up disconnecting which stopped the motors but when I reconnected it started up anew. A friend sent this board to me, I thought it was going to be a real SmoothieBoard until i took a look at it. I am using the dc42 fork of RRF, and I must say, if you're reading this, dc42, your work on the firmware and PanelDue are absolutely fantastic. alpha_max_endstop nc # NOTE set to nc if this is not installed They are not configured just like the smoothie wiki because they are NO when plugged in… That’s when I add the “!” invert and M119. Implemented in many other firmware like marlin or teacup …. » is incorrect. hi i … How to find out if a preprint has been already published, Piano notation for student unable to access written and spoken language. In the meantime, if your machine is capable of harming itself, please install min and max endstops and enable limit_switches. 3D Printing Stack Exchange is a question and answer site for 3D printing enthusiasts. Negative moves do not work on the X and Y axis with endstops. Disable endstops and keep them enabled when not homing. You can connect two motors to a single driver, that’s no problem, it’s how most people do it on i3-type machines. Does that answer your question, or was there more to it ? gamma_homing_direction home_to_min # Or if I click the move motor buttons pronterface will move it to whatever I want regardless of a switch. Make sure your job has a work offset if you use the endstops. The version of Marlin that I use (Bugfix 2.0x (and all other current versions I presume)) **doesn’t react to a Stop command until after the current move has completed. Most additions to the wiki are related to requests by users, every time I see something that isn’t documented and that is talked about in a forum/mailinglist/G+ etc, I try to add it to the documentation. Configuring Marlin is very simple, so there is not much magic to get sensorless homing to work. Endstops on X and Z axis seem to be working correctly but Yaxis endstop seems to have no effect. Enable DEBUG_LEVELING_FEATURE and M114_DETAIL and re-flash the firmware. Any suggestions, advice, or input would be welcome. Then, if the endstops show as triggered all the time, your endstops are probably not 3.3V compatible and you need to modify them - see Connecting endstop switches. The endstops are wired NC -> top on the axis’. There is no mechanical failure with the switches, I've tested it with a continuity tester. Angular momentum of a purely rotating body about any axis, Ceramic resonator changes and maintains frequency when touched, White neutral wire wirenutted to black hot, Get app's compatibilty matrix from Play Store. I finally said screw it, if I break it I break it! Could you please explain what I should do ? To test, I have pressed one of the endstops with a finger and have moved the connected axis (in both directions) without the endstop stopping movement. Work offsets. Because, for now, after homing all the axis (which it does correctly, stoping once hitting mins endstops), if I say to smoothie to go backwards on any axis (which obviously physically cannot do since it is on the endstop min) it still force like a dull, by the way eating my belts on the motors pulley teethes … same for max endstop. How far would we have to travel to make all of our familiar constellations unrecognisable? @Ulysse31 I’m confused about what you are trying to achieve and would really like to understand the rationale behind your request?! I would like to have them separate for auto level but I may try to join them on the same driver. As expected things go wrong. We do not have software endstops, we are working on implementing those ( it’s more complicated than you’d expect, it’s the only major feature we are still missing ).
