SuperSlicer won't extrude first layer
Hiya,
Been trying to get Superslicer to work again as I'm having some print quality issues with Orca. However SS doesn't want to lay down a first layer irrespective of the version. It used to be fine but for some reason doesn't want to work anymore
Attached is a succesful print from Orca (30x30x0.2) cube and the identical failure from SS. Running on a VC300 with RatOS 2.1 and Beacon Contact.
I've compared the slicer profiles and they seem identical. Attached also the GCODE of all three SS variants I've tried.
Hoping someone might have some ideas of what the issue might be as I am having no luck figuring this out.

What does the slice preview look like?
In all cases looks pretty good - see attached screenshot.
Looks same as on mine. There is a setting I've seen that gets rid of top and bottom layers, i've seen it used to make a filter where the middle is just infill
But the image there shows that it should be doing the bottom layer. Weird
Does the printer move like its doing the bottom layer, just nothing comes out?
Yeah - it’s happily chugging along.
For a while I went into the woods that it might be retraction settings but the machine settings on Orca and SS are the same
in SS, what do you have in Start G-code?
wait, it moves like its trying but nothing comes out? That suggests a clog doesn't it?
START_PRINT EXTRUDER_TEMP={first_layer_temperature[0]},{first_layer_temperature[1]} EXTRUDER_OTHER_LAYER_TEMP={temperature[0]},{temperature[1]} BED_TEMP=[first_layer_bed_temperature] INITIAL_TOOL={initial_tool} TOTAL_LAYER_COUNT={total_layer_count} X0={first_layer_print_min[0]} Y0={first_layer_print_min[1]} X1={first_layer_print_max[0]} Y1={first_layer_print_max[1]}
Mine is JUST
you'd think so - but I ran it after just finishing a 2 hour print, and runnning another printer after is without issue
Yeah - this is the new first-layer when running 2.1 and beacon; As per the new guide RatOS 2.1 Slicer gcode settings

Wonder if that first layer stuff is messing with it
It's same I have on Orca 😄
OH! I have no idea about anything custom for 2.1 yet. Haven't upgraded
hmmm, i saw something in the ratos channel about separate objects. See if we can find that to rule it out
hm, that was unrelated it seems

yeah - and looking in the GCode I\m not seeing any weird Z moves either. Except for first layer being 0.25 in SS and 0.2 in Orca but that shouldn't matter
extruder set a tiny bit different, 0.6 vs 0.5, but I also think that difference shouldn't matter
SS is missing the M83
Set it to view Expert settings then:
Printer Settings > General > Advanced (at the bottom) > Use relative E distances
That's interesting as it is set.... Maybe I\ll manually add the M83 to the GCode and see what happens.....
I can also see it in the G-Code as 'relative_e=1' curious
Huh - that was it
What the hell - guess it's over to the SS github and report a bug
Thanks for your help @TheTik !
happy to actually find something! First time I've found something useful in gcode 😄
