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 edge

@Carlo Interesting. I guess it doesn't like the arc.

@Carlo Can you please upload the full file?

@chrishamm

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.

@chrishamm

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.
