Duet Wifi Unable to get past warm-up

I cut the other lines from the Gcode file - its my understanding it goes sequentially and never gets to the skirt anyway, so the issue would be up top. I can post the full file if desired - its just movements however.

One problem I can see is that you are using Cura, which always outputs absolute extruder moves, but you have M83 in your config.g file. I suggest you add M82 to the start gcode in Cura.

But this doesn't explain why the print completes at layer 1. We might need to see more of the gcode file.

What would be the preferred slicer for this board? I'm not exactly sold on cura, it just appeared to be everywhere at the moment so i thought i'd give it a shot. I used to use Skeinforge, but i was looking for something a bit more straightforward…

Cheers for the advice thus far!

Please can you put that gcode on a file sharing site and then edit that last post to link to it instead of including all of it in that post. I am using a tablet and it would take me forever to scroll to the bottom of that post.

Does the G28 homing command complete before DWC says the print is complete? I am wondering whether something in your homeall.g file could be to blame.

I have updated the original post with a link to a paste site. The G28 command doesn't run or at least doesn't run fully. I'm not sure what order G28 actually runs in but i have heard a click (like the endstop un-triggering perhaps, or a relay potentially) prior to the print saying 'completed'. It all seems a little odd to me.

G28 homes the printer. If you send G28 from the console, does the printer home correctly?

Alrighty, seems things are a little odd when i run that command (whee, getting somewhere!).

To explain the behaviour; its a corexy printer, running g28 when;

• the x/y endstops are triggered, only the z axis moves, homes normally and then stops.

• The X endstop is triggered alone, y moves back into position & rattles in place (trying to drive) once endstop triggered

• The Y endstop is triggered alone, x moves into position & rattles in place (trying to drive) once endstop triggered

It appears that those two endstops aren't stopping the x/y axis when g28 is run. Using the +10/-10 triggers however, the endstops are adhered to.

[dc42]

I can see 3 problem with that homeall.g file:

• The line "Move away from the endstops" begins with a colon instead of a semicolon. Fix that and I think your print will work.
• The G1 command on the line following "Course home X" should have S1 at the end
• Same for the line after "Course home Y". Fix those 2 and homing should work.

We will fix configtool to generate these lines correctly in future.

[deckingman]

Looks to me like you are missing few "S1s" in your homing file.

Going through your homeall file it's fine up to course home X and Y. The next command you have is
; Course home X
G1 X-205

That should be G1 S1 X-205 (the S1 tell it to look for an end stop to be triggered)

The following line is the same. That is to say G1 Y-195 should be G1 S1 Y-195.

The rest looks OK at a glance.

Edit. Was typing while DC was typing (and I missed the colon that David spotted).

Thank you dc42! (& deckingman!)

I'm now able to extrude plastic. That was a little tougher than i anticipated but have a position to launch myself from.

Thank you very much!

Glad to help, and I'm sorry that configtool introduced those errors.
