MPCNC Endstop G28 Issue
-
These are the endstop pin names
Endstop inputs Label Pin name X_STOP xstop Y_STOP ystop Z_STOP zstop E0_STOP e0stop E1_STOP e1stopSo I'd do something like...
M574 X1 S1 P"xstop+e0stop" M574 Y1 S1 P"ystop+e1stop"X1 Y1 means the endstop is on the low end of travel.
P"pinname+pinname" means it will use both those endstops when you home the axis with a G1 H1 X move, etc for Y. the order of the pins needs to correspond to the order of the motors in M584. -
@Phaedrux Thank7you I really appreciate your help! Okay so I think I've set up the endstops correctly, but when I try to home all the axis just moves maybe +10 in X and Y and comes up with failed to enable endstops
This is what I have the endstops as:
; Endstops
M574 X1 S1 P"e0stop+e1stop" ; configure active-high endstops for low end on x via pins e0stop and e1stop
M574 Y1 S1 P"xstop+ystop" ; configure active-high endstops for low end on y via pins xstop and ystopAnd this is my Home All file:

And you have them plugged into those ports on the board?
Can you please post your entire config.g as it is now?
Also please send M122 and M98 P"config.g" in the gcode console and report the responses.
Can you also confirm that the direction of rotation of the motors is correct? Move the head to the center while the printer is off. Then power on and send G92 X100 Y100, and then send a G1 X10 Y10. That should move the head away from the endstops (since they are at the low end)

@Phaedrux
I used the duet config website to generate this config so I'm not sure what all the errors in M98 are about? The G1 command moved everything towards the 0 point of each axis is that right? I currently have the motors set so that if I press X-50 it moves towards 0 and X+50 is away from 0. The endstops are on the truck carriages and should trigger when the axis reaches 0current config:

Your firmware version is quite out of date. I suggest you update.
It's as easy as uploading a zip file to the system tab in DWC.
Here is the latest release: https://github.com/Duet3D/RepRapFirmware/releases/download/3.4.6/Duet2and3Firmware-3.4.6.zip
Upload it as is, do not extract it first.The changelogs are here: https://github.com/Duet3D/RepRapFirmware/wiki/Changelog-RRF-3.x#reprapfirmware-346

This sounds fine, but the assumption is that the 0,0 point is on the front left of the machine to give you a left hand coordinate system to match what you'd see in CAD software or a slicer.
So -X would move left, +X right, -Y to the front, +Y to the back.
Does that match what you're seeing?
-
@Phaedrux Yes that's correct, I have it setup as CAD because that's what I'm familiar with. I'll update the software now and see if that makes a difference

@Phaedrux I've been able to change the endstops in M574 with the ! to flip the endstops so they work correctly. Now if I try to home X or Y only 1 motor is activating. What commands do I need to put in so that it will activate both motors independently?

I think I've figured it out all good. It's showing as homed on X and Y with the endstops triggered. Thankyou so much for your help!

@ZPomeroy said in MPCNC Endstop G28 Issue:
it's moving the Z up, then jutting back a few mm (in the + direction) and moving Z down again.
This indicates that the endstops are already triggered at the start of the homing moves. The jutting back is the back off move. You've already solved it by inverting the pin logic.
Glad you got it all going now.
One last thing, just to make sure your firmware update went smoothly, can you send M122 and M98 P"config.g" once more?
-
@Phaedrux After a few days break I'm back at it and am having an issue with homing. When I try to home X the 2nd X motor (X1 is driver 0, and X2 is driver 1) gets stuck right before the endstop would usually be triggered and starts shaking violently. The same thing happens when I try to home Y, the 2nd Y motor (Y1 is driver 3 and Y2 is driver 4) starts shaking violently and making a horrible noise when it gets to the endstop. Any ideas what might be causing this?
Here's the M122 and M98 readouts from previous. Looks like it updated correctly

@Phaedrux I'm still having issues but I'm not sure why. Sometimes the motors will skip and start making a horrible noise when the endstops should have been triggered. The other issue I'm having is I don't know how to home Z without a Z probe? I've got M558 in config.g. How do I tell the board that the Z axis is homed?

In your homeall you're doing a homing move as if you have an endstop to home to, but you don't have a z endstop defined in config.g
How do you intend to home your Z axis?
Right now you have a manual probe defined, so it would prompt you to manually jog the axis to touch the Z0 point. To use that you would need to modify your homez and homeall and change these lines

Can you give me detail about this? Maybe a video showing what is happening?
Do it happen every time? Randomly? Does the axis move normally otherwise?
