RE:
Will check, thanks for the quick replyl!
For now the issue seems resolved by enabling the wipe tower with No sparse layers selected, making it only 1 layer,
still have to catch some filament deposits when the extruder returns to the last position before the M600 [using ultra fine tweezers seems better then trying to use pliers] but the blob is deposited into the wipe tower
thinking about editing out the return to last position in the gcode, but for now should be enough to finish this batch of prints
RE: Blob when printer restarts after manual color change.
update, adding a loop around the object of 2 layers solved the 'touch last position' with the M600 command.
combined with 2 layers wipe tower - no more unexpected blobs and extrusion on the models
RE: Blob when printer restarts after manual color change.
I'm also suffering from this issue now having print aafter print fail du to it. And I don't think it's slicer related but firmware how the M600 works.
My prints are flawless, the filament change goes fine, when I say I'm ready the nozzle starts to move to where it needs to. So far so good, but here comes the fail.
Once at the print start spot the nozzle pauses and sits there, then extrudes a HUGE blob, enough is extruded that the printer complaints about a stuck filament and starts grinding. It then return to the change spot and ask me to reload which it does fine, then continue printing. But more often than not the print is ruined because the nozzle hit that big blob hard and gets knocked out of position causing layer shifts, it it didn't the first time it will do it the next round.
If it wasn't for this weird pause and mass extrusion after a change I would have absolutely flawless two-tone prints.
I've tried deleting the after filament change gcode or changing the value of it, none of that makes any difference, I've tried with and without wipe tower, no difference. Not even using PrusaSlicer.
