Duet3 + Pi DWC freezing
-
Hi Chris,
It was not possible to just reload the page as gcode files would not start it would heat as expected but on initial movement would then try to home and not recognize the endstops so I installed DSF etc from a standalone raspbian install which has fixed the freezing but not the unable to print with the same issues as above also cannot use the webcam in DWC as it causes DWC to restart with out displaying error on each attempt though I can view the Pi cam from the web browser.
This is on 3.1.1 as per apt get.Cheers

@Carlo said in Duet3 + Pi DWC freezing:
this minor issue ?
Sorry what's the minor remaining issue in a nut shell?
-
That when G-code is loaded it results in unexpected movement at the start of a print like the nozzle being plowed in to the bed or homed with the carriages crashing at the end stops and without the Pi files print as expected.
Cheers

Does this have any meaning in the issues I'm having ?

So received my new Duet 3 yesterday so new board new cable new installation DuetPi
nothing else attached same issue works perfectly in stand alone and does everything in SBC mode but print ...If I use DuetPi it will start the print then head to the endstops but wont stop at them after a few seconds but if I build PiOs install DSF etc it heads the other way and ploughs in to the bed but at the same point everytime after a few seconds to the mm?
with the motors screeming and M122 shows no errors everything is peachy as far as the board is concerned ...Turns out its the purge line in my start code.. which works fine in standalone mode but not SBC SBC "worked" without it Huh? Quotes well A print
Is it the spacing of the lines printing at the moment so can't retry right now but like to know how it ends.
any ideas ?
; Draw arc to prime the nozzle between 6PM and 9PM on the bed edgeG1 X0 Y-175 Z0.25 F6000

@Carlo Interesting. I guess it doesn't like the arc.
-
@Carlo Can you please upload the full file?
-
Its any with that start code so here you go a small one it gets about 10mm in to the purge arc then thats all she wrote
-
@Carlo Thanks for the file. I could provoke an error that will be fixed in v3.2 but I am not sure if it is related to the problem you reported. I'll try your G2 code on Monday when I get back and report my findings.

Only posted in case its of help to you guys if it is actually a bug ...now with leaving it out of my slicer my SBC setup is printing beautifully and I simply set 0.5mm unretract before start of print so no purge needed in PSlicer so all good.
