Endstop not working on delta with duet 2
-
Hello everyone.
I've been having some issues with the endstops on an FLSUN Q5 delta printer.
I've replaced the old board with the Duet 2 wifi. Firmware version 3.4.4M115 FIRMWARE_NAME: RepRapFirmware for Duet 2 WiFi/Ethernet FIRMWARE_VERSION: 3.4.4 ELECTRONICS: Duet WiFi 1.02 or later FIRMWARE_DATE: 2022-10-20 16:17:41I have everything wired in correctly and it's mostly working.
I am however having an issue with the endstops. When I home the printer, the movement crashes against the endstops and wants to keep going. Then DWC shows an M121 error with insufficient axes homed.
I can see all the motors and axes working correctly.
Testing the switches with the M119 command shows the switches working correctly.M119: Endstops - X: not stopped, Y: not stopped, Z: not stopped, Z probe: not stopped ; nothing triggered M119: Endstops - X: not stopped, Y: not stopped, Z: not stopped, Z probe: at min stop ; Z probe active M119: Endstops - X: at max stop, Y: not stopped, Z: not stopped, Z probe: not stopped ; X stop active M119: Endstops - X: not stopped, Y: at max stop, Z: not stopped, Z probe: not stopped ; Y stop active M119: Endstops - X: not stopped, Y: not stopped, Z: at max stop, Z probe: not stopped ; Z stop activeThis is my config.g.

These are the switches - https://www.ebay.com/itm/334506838039
I can't even find this kind anymore! Perhaps I need updated ones.Any help is appreciated.
Thanks. -
@sgtconker1r Can you post your homedelta.g from the sys folder, please?

Sure.

A day later to think about it. I now notice some issues with my homedelta.g
All the axes need to be the same value, not just the Z.
I'll try this update later when I'm off work.. . . Seems so obvious after the fact. Perhaps it just helped to write it down.

@sgtconker1r Yes. The X,Y,Z values should be the same on a delta.
But i think, with G1 H1 it should stopping anyway at the endstops...!? -
@sgtconker1r your config looks OK to me.
The usual reason for not stopping at endstops on a delta is that the endstops are on the wrong towers, e.g. the X endstop is at the top of the tower with the Y motor. So I suggest you test the motors and endstops individually as described at https://docs.duet3d.com/en/User_manual/Machine_configuration/Configuration_linear_delta#testing-the-motors-and-endstops-individually and make sure the endstops are consistent with the motors. Looking at the machine from the front, the X tower should be on the left, the Y tower on the right and the Z tower at the back.

This is what was wrong with my setup.
It seems the wiring was mislabeled from the very beginning.
Now the homing works correctly.
Solved.
