These errors are complaining that you're specifying E values for those commands, but don't have an extruder motor defined. So just delete the E values from those commands.

RepRapFirmware for Duet 2 WiFi/Ethernet version 3.1.1

Your firmware version is quite out of date.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

@ZPomeroy said in MPCNC Endstop G28 Issue:

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 0

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?

ZPomeroy

@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?

ZPomeroy

@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

Please post your config.g as it is now.

It looks like you still have all the E values present causing those errors.

Make those adjustments and run M98 P"config.g" again and see if your homing issue is still there.

Also make sure the homing move is long enough to guarantee an endstop hit from the farthest point.

ZPomeroy

@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?

Phaedrux

@ZPomeroy said in MPCNC Endstop G28 Issue:

G1 H1 Z-125 F360 ; move Z down stopping at the endstopG90 ; absolute positioningG92 Z0 ; set Z position to axis minimum (you may want to adjust this)

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

G1 H1 Z-125 F360        ; move Z down stopping at the endstop
G90                     ; absolute positioning
G92 Z0                  ; set Z position to axis minimum (you may want to adjust this)

To simply G30 so that it would call the probe and prompt you to home Z manually.

@ZPomeroy said in MPCNC Endstop G28 Issue:

Sometimes the motors will skip and start making a horrible noise when the endstops should have been triggered.

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?
