driver phase disconnected
Yes that could indicate exactly what it says, a disconnected phase of the motor wiring, either a bad wire, corroded connector, or even possibly a bad driver. But the fact that this is a different board than the one you started with I would suspect that it's not the driver but actually the wiring. And from the salt air comments, I'd think corrosion. Unfortunately, disconnecting a motor while it's running like that is a good way to damage the driver chips, so best to get that sorted before doing too much heavy testing.
-
You may need to test your z motor movement by itself to see if it needs to be reversed or if the steps per mm are correct.
You can send G92 Z0 in the console to force the Z axis to act as homed and at Z0 position. Then you can use the jogging buttons to attempt to move it up and down. Start slowly. If possible, adjust the z axis manually to get it clear of the physical endstops first.
-
Yes...I'm with you on that. I'm thinking corrosion as there's no movement of the cables at the plug ends. There was certainly plenty of corrosion on the second/unused extruder driver pins. I've got plenty of slack there, so I might drag the cables through a bit and redo the crimps/plugs both ends.
You're talking about the Z sensor height setting procedure? Yes I can do that. I'd forgotten about G92 Z0 allowing it to move "unhomed".
Another issue is that I can't use the house wifi as it's too weak in the garage, and I want to cancel the contract on the dongle I've used in the past. My phone has a 5gb monthly quota that I never use, and when I tested it's signal as a hotspot it was much stronger than the dongle. I would like to use that, but I've already connected this board to the house wifi via YAT, and it doesn't seem to want to change by the same method.
Can I do it via the DWC?
-
The easiest way to add another wifi network is through the gcode console.
Use M587 to add the new SSID. At boot time, the Duet should choose the SSID with the strongest signal.
-
Belay this one, all good now
It's never ending...
Now when I try to open the DWC, I get this message:
Browsing via the MMS proxy is not allowed. Please use the browsing proxy 10.1.1.181
And that address won't open either. I was only on there a minute ago.
Any suggestions (and thanks again for all your help)?

Mate, you're an absolute champ! (don't mean to gush).
It's all working, and surprisingly my old Samsung Galaxy S6 with custom ROM absolutely pounds out a strong wifi signal.
Obviously I've got to re terminate these cables and setup all my homing files etc, but I'm seeing a light at the end of the tunnel.
I won't say "one last thing", because it's possible it won't be, but is there a way to revert the DWC back to the old format without losing any functionality? I'd really just prefer to see the old school screen, I was pretty familiar with that.
-
OK, so straight back into trouble.
I'm trying to calibrate the Z probe trigger height, and it's not playing the game at all. I've done this procedure plenty of times in the past.
I'm raising it until I grip the sheet of paper, then G92 Z0, down 10mm, then G30 S1 and that's where it plays up.
Instead of just staying in the center of the bed and lowering the nozzle to the bed (or raising the bed to the nozzle), it tries to home X, then Y, then moves to a random position and lowers the nozzle just a little.
Never seen it do all that from G30 S1 before...can anybody help?
-
should be G30 S-1

Cheers mate. It actually did exactly the same thing with that command too.
Wondering what I'm missing here
-
I'd call the extruder issue resolved, and I'll start anew with my tuning issues in the tuning and tweaking section.
Thanks for the help Phaedrux, appreciated
