Solved Extruder stopped working
-
If you have your old config files on the SD card, you might be able to upload the config.json file to the web configurator, but 1.15 is quite old.
If you use the same SD card and config file on the new board it may work, but it would depend on what firmware is on the new board as many things have changed since 1.15.
I think your best bet may be to follow this guide for getting the latest firmware onto the board, and then using the web configurator to generate a new set of config files.

Cheers again.
I think I'd be best off running the configurator, and using the old config file for reference.
I'll give that a go, and thanks very much for your help.

Ok...so this just gets stranger.
I did upload the json file into the configurator and it worked, at least for dimensions and directions. The bed heater temp is OK, but the extruder is reading 2000degC. I've got a feeling that it's thinking I've got a PT1000 installed, not a PT100?
But I've still got the same problem with the extruder...nothing. This is with a brand new board, fully updated. I've checked the continuity of the wiring continuously, and today I made a short harness which I (after rechecking its continuity) fitted straight to the board with 2 different steppers. Same thing, won't extrude via extrusion menu or load filament option.
How is this possible??
I guess now I've got to check the output direct from the board...what would volts (ac/dc?) would I be looking for at the pins when stepper is activated?
Would there be a wiring fault in another part of the board that could cause this?
Bear in mind that this machine has never broken down in 3 years, and while my programming is crap I have a very big background in wiring harnesses and looms, and all the right equipment. I just can't see now how this is happening.
David/Staff...could you please help me out here, as this is getting tricky?

This new board won't hold the wifi connection either...keeps dropping out unless I've start the wifi module with YAT.

See my note above about cold extrusion. You either need to heat up the extruder or send the command to allow the extruder motor to move without being at temp.
I've start the wifi module with YAT.
Do you have a command in your config.g to enable networking?
Can you post your config.g file?
-
Thanks Phaedrus,
I do appreciate your continued and patient help.
The loss of connection is simply wifi range. I've moved the machine into the living area where signal is strong, and it's staying connected. On the previous motherboard I had a dongle in the garage (which costs and extra plan), and this time I was trying to connect to the house wifi which is unlimited. We have a range extender in the hall to the garage, but it's not helping unfortunately.
I was aware of the heat to extrude rule, but the machine broke down while hot and in the middle of a print, and before I stripped it down I heated the extruder to try and test it. Right now the extruder temp is reading 2000.0 by the way. If you want to add a command to ignore extruder temp for now, that's fine with me and will probably be helpful.
Here's my config.g file. I don't think I've changed anything since the configurator.

If your PT100 is connected to the first port on the daughterboard this command should be
M305 P1 X200That might solve your -2000 temp problem, which may solve the no extruding problem.

That got it (thank you), but I'm not convinced we got the root cause. Temp is now correct. Obviously the json file doesn't upload exactly to the configurator, but I'll take what it's given me.
When I first fired it up, I got a "driver phase disconnected" message, something to that effect.
I plugged in my test motor/lead and it worked in reverse and too fast, so I dialled back my steps/mm and reversed it, all good. I plugged in the usual motor/wiring, and it worked this time. I wiggled the wiring around, but can't reproduce the fault (intermittent, the worst kind). If it goes out to lunch again in the middle of a print I know I have to rerun the long and difficult extruder wires. I recrimped the ends (but it didn't work for a while still), or maybe there was a dirty connection after all these years, but if it does it again it's a rewire for sure.
Are you staff Phaedrux? Do you mind taking me through some other things? I'd greatly appreciate it. Once I've got it up and running I'll be fine to adjust my bed height etc, and I'll go back to old posts to see what I did with probing etc.
I'll start with Z homing...won't do it. Homes X and Y correctly, but Z won't home or respond to commands. I'll post my homing files. I haven't set my IR sensor yet either.

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

@jay_s_uk said in Extruder stopped working:

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
