Only two of three towers are homing

[Velvia]

When I use the "Home all" command, only two of my towers are homing. All towers move just fine when I use Z +/- movements. Any ideas?

[Phaedrux]

You're going to have to be a lot more specific. I assume this is a delta as you're talking about towers.

Which two towers?

Can you post your config.g and your homedelta.g files?

[Velvia]

@phaedrux Yes, a delta.homedelta.g config.g

Tower Z and Y home just fine, but tower X does nothing. The stepper gets charged though.

Edit, didn't know how to imbed the code:

Can you send M122 and M98 P"config.g" in the gcode console and copy paste the results here?

@velvia said in Only two of three towers are homing:

All towers move just fine when I use Z +/- movements.

How exactly are you testing movement? What commands are sent or buttons used? How are you allowing movement if homing isn't succeeding?

I use the Z buttons here. Then everything moves just fine. When I press "Home all", only Z and Y moves and homed correctly, X does nothing.

It looks like your DSF version and firmware version have gone out of sync.

Can you try sending sudo apt update and sudo apt upgrade on the pi and then run M122 again and post it here?

Everything should be on 3.4.1 at this point.

[Velvia]

@phaedrux said in Only two of three towers are homing:

I already did this prior to all this. I'll do it again.

[Phaedrux]

Do you get any errors?

[Velvia]

@phaedrux said in Only two of three towers are homing:

Two errors in the beginning of "sudo apt upgrade", then everything else is fine.

[Phaedrux]

Don't leave me in suspense. What are the errors?

[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!

[Phaedrux]

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!

[Velvia]

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

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.

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).
