Only two of three towers are homing

Velvia

I don't remember. Was many hours ago, restarted the printer after that. Looked like it just failed to fetch the two first things. I'll try again tomorrow. Thanks a lot for the help so far!

You may want to download a fresh copy of the Duet Pi image and flash a new SD card. You can backup your printer config files and restore them. That may be easier than trying to get things back in sync on the current install.

Velvia

Thank you, I'll try that!

Flashed new image, updated and upgraded, no errors. Problem persists. M122 gives this:

3.2.2

Your firmware still isn't updating.

Can you try sending M997 in the gcode console to manually initiate a flash of the firmware? Then check your firmware version again with M115. It should be 3.4.1 to match the version of DSF on the Pi.

Well it was worth a shot and likely fixed other future issues as having a mismatch like that will cause havok eventually.

; Drives
M569 P0.0 S1 ; physical drive 0.0 goes forwards
M569 P0.1 S1 ; physical drive 0.1 goes forwards

M569 P0.3 S1 ; physical drive 0.3 goes forwards
M584 X0.0 Y0.1 Z0.2 E0.3 ; set drive mapping

The only thing that stands out as odd to me is the motor direction config for X Y Z motors has X Y going forwards and Z going backwards.

Which towers are not moving correctly during homing?

Take a look at this test please: https://docs.duet3d.com/en/User_manual/Machine_configuration/Configuration_linear_delta#testing-the-motors-and-endstops-individually

This worked just fine. All towers moved individually as they should.

Velvia

@velvia
That makes this so weird.
H1 terminate the move when the endstop switch is triggered and set the axis position to the axis limit defined by M208. On delta printers, H1 also selects individual motor mode as for H2. Normally used with relative motor coordinates (see G91).

@velvia most likely the X endstop switch is not connected properly. Use M119 or the Object Model DWC plugin or the Endstops DWC plugin to test that endstop switch.

Velvia

@dc42
M119 gave me this:

M119
Endstops - X: at max stop, Y: not stopped, Z: not stopped, Z probe: not stopped

So I'll check the connections. Just figured it worked since the light is on and responds.

Edit: that was the issue. Crimping these tiny cables and connectors are annoying
Thanks everyone for your help! I have other issues as well (hotend not heating, hotend fan always on even though it has temperature control), but will make a new thread for those I guess.
