Thanks for contributing an answer to 3D Printing Stack Exchange! Testing repeatability of the probe. First, my endstops are supposed to be working properly (checked with M119), but when homing one of the axis’ (random) will just keep going and crashing into the endstop. 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. I have everything assembled and wired up. So to make it clear: Smoothieware does not support software endstops aka. 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. Configuring Marlin is very simple, so there is not much magic to get sensorless homing to work. If you where to cut out that part it would result in going negative past your endstops and misalign your machine. After firmware (2.0.7.2) is uploaded, I experience 2 issues: The LCD is showing 2 lines of squares where I expected the Marlin logo first and then the default home screen. Stack Exchange network consists of 176 Q&A communities including Stack Overflow, the largest, most trusted online community for developers to learn, share their knowledge, and build their careers. What else would you expect machine to do if your code try to operate outside of machine range (hence the code is obviously generated wrongly). "it is possible that the endstop pin on the Atmel chip is not working anymore. Is the line uncommented ? I have a couple of questions though. 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. This issue cannot be closed. a logical comparison agains a stored min and max value (set on homing) which prevents the machine over- and under-running its axis dimensions? Marlin has support for four temperature sensors (three extruders, one heated bed). If yes, why is it not simply and clearly written like that on the documentations ? I have edited the config and tried with and with out the ! 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. 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. I just set up a MKS SBase 1.2 I have everything figured except for two things. Documentation has been updated since the end of February !! If the seller is unable to help you, feel free to ask again here. To test, I have pressed one of the endstops with a finger and have … 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. Im having an issue after flashing my Rambo 1.4 to Marlin 1.1.9 with dual endstops and LCD support. When I home (in Pronterface Here) in the Y direction its as if the endstop is not even connected no response form the switch. it will only lead people to feel fooled once those kind of troubles are discovered. 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…….! 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. As expected things go wrong. beta_max 200 # 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. 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. I've checked M119 and all three of the endstops show to be triggered when manually pushed. I have this switch plugged into first header column for X-min. 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. I uploaded the standard delta marlin and when I go to home the axis', they keep trying to move up after they trigger the endstops. 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. Could the US military legally refuse to follow a legal, but unethical order? UPDATE: HURRAY !!! beta_min_endstop nc # I have searched and read lots of posts but nothing fixed the issue. I've tried changing home position. The hard endstop result in a halt state yes, which then requires M999 to get out of. I have took a look to the limit_enable thing => it is clearly too drastic ! PS: @Dytoractor : did you found a way to avoid this ? A typical part has the gcode built with the origin at the parts corner. move_to_origin_after_home worked last time I tried it ( and it was with a beta axis homing to max too ). » is incorrect. My X and Z endstops work Perfectly. Here we can tell the firmware what the limits are of the travel zones. You can have “hitting end of axes causes the movement to be ignored”, which is what you asked for ( correct me if I misunderstood ). load or back up SPI Flash and SD. on the axis’. I have tested that my endstops function by sending M119 and verifying that the endstops correctly show OPEN or … @arhi: what I want ? There is no mechanical failure with the switches, I've tested it with a continuity tester. 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 … I want to insist that « hardware endstops only work for homing action, or as a kill switch. The unused extruder driver/s are used for the extra stepper/s. I’m using a Ramps 1.4 board with the Marlin-MPCNC_Ramps_T8_16T_LCD_32step_DualEndstop firmware. The way this is done is by homing the machine so it knows where it is. How do others use this correctly? Then the machine is able to ignore moves that would go out of the machine area. Also check for continuity again, using a multimeter. If you have any endstops not behaving you turn off the printer, unplug the USB and Check the pin-connection.Correct as nesccesary. I am having problems with my Y endstops from working . I found the way the limit switches are implemented (machine full stop) to be overly dramatic for my use case. 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. BUt Y does not . Please, update your documentations, state the things has they are not has they will in a potential future, and don’t leave misunderstandings on it. I’ll download the latest edge firmware and configure the soft endstops as documented ^^ !! Implemented in many other firmware like marlin or teacup …. alpha_homing_direction home_to_min # or set to home_to_max and set alpha_max Could you please explain what I should do ? How to symmetricize this nxn Identity matrix. #corexy_homing false # set to true if homing on a hbit or corexy 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. Yes, this is not supported. 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. … 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. 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). I did end up disconnecting which stopped the motors but when I reconnected it started up anew. Apparently it is a bug for MAC but i am using WIndows 8.1. 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 ). Bed Leveling. beta_limit_enable false # set to true to enable Y min and max limit switches this is 3d printer hardware protection basics. I think I had the wrong idea of what an endstop did as well. Marlin indicates this by blinking question-marks in place of X, Y and Z on the LCD screen (v1.1.8 and older) or blinking ‘?’ in place of the coordinates besides X,Y and Z (Marlin v1.1.9 / v2.0.0 and newer). I have everything but two 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. A second issue I have, is that after homing (which works fine) the config flag “move_to_origin_after_home” is ignored / not executed. Issue the command M111 S247 to enable maximum logging. It can be caused by static getting into the pin from the endstop wiring, Ive seen a few of these happen on X3s and X3 Pros. Soft endstops is in a separate branch for now because it’s not documented yet, but we expect it’ll get integrated very soon ( we looked at it just a few days ago again ). 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. By clicking “Post Your Answer”, you agree to our terms of service, privacy policy and cookie policy. Bonjour à tous, It’s me again, was away for a long time … my projects were on stanby for some problems I had … If I am wrong then the machine tries to make it to 200mm by brute force! control M121 - Disable Endstops. 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 …”, "A reset will be required to continue, or sending M999, make sure you move away from the endstop though before trying to move. Or if I click the move motor buttons pronterface will move it to whatever I want regardless of a switch. That’s just a guess. To subscribe to this RSS feed, copy and paste this URL into your RSS reader. 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. Below is a link to a video I shot testing all of the axis’ against one of the endstops. Disable endstops and keep them enabled when not homing. What sort of work environment would require both an electronic engineer and an anthropologist? If I would have homed the Z axis instead of clicking it many times it would have stopped my machine? The endstop did not stop any movement in any direction. So from this conversation, I am understanding that only Homing works?
