Hi guys!
Can you help my solve problem with 3D printing?
What i have:
- Original Prusa i3 MK3S
- MMU2S
- BB3D Retractable Purge Mechanism
- PrusaSlicer 2.3.1
- P2PP 7.01.10
- Octoprint
I purchased, assembled and installed a BB3D Rectractable Purge Mechanism on my prusa i3 MK3s 3D printer (with MMU2S).
I guess I followed all the steps in the pseudo-manual correctly (really bad manual, especially for beginners 🙁 ). I have downloaded P2PP and configured all the settings in the Prusa slicer as follows:
and
I did "Purge location test.gcode" and updated the purgepostion parameter in start gcode in prusa slicer as well as "Purge blob test.gcode" - everything went fine - blobs look fine.
Problems arise when I wanted to print my own gcode generated in prusaslicer. I am using Octoprint and after trying to send my gcode to Prusa, I got the error "not sending M0 to the printer ...". I found advice to put "DO_NOT_GENERATE_M0" in the gcode boot section - I did, but nothing happened - the "M0" were still in freshly generated gcode. I cut that bad "M0" out of my gcode and tried to start printing.
I checked the final gcode and everything looks fine, first warm up the nozzle & heat up the bed, then calibrate Z, calibrate MMU2S, take filament to the heated up nozzle...
But finally when i sent gcode to printer. On prusa LCD in heating section there were [temp. nozzle/0], [temp. bed/0] (it should be [temp. nozzle/215] and [temp. bed/60]) - it should heating up at first.
Instead of that Extruder is trying to take filament to cold nozzle...
Ofcourse everything is stuck at this moment.
When im trying to print the same project, but g-codes are generated from my normal profiles in Prusaslicer (without P2PP) everything going well.
My basic script in start g-code section in Prusaslicer:
;P2PP PRINTERPROFILE=e000000000000001
;P2PP BEDORIGINX=0
;P2PP BEDORIGINY=-10
;P2PP BEDSIZEX=250
;P2PP BEDSIZEY=220
;P2PP SPLICEOFFSET=40
;P2PP MINSTARTSPLICE=100
;P2PP MINSPLICE=80
;P2PP EXTRAENDFILAMENT=150
;P2PP LINEARPINGLENGTH=350
;P2PP MATERIAL_DEFAULT_0_0_0
;P2PP ABSOLUTEEXTRUDER
;P2PP PURGETOWERDELTA=0
;P2PP BIGBRAIN3D_BLOBSIZE=40
;P2PP BIGBRAIN3D_COOLINGTIME=20
;P2PP BIGBRAIN3D_PURGEPOSITION=253.2
;P2PP BIGBRAIN3D_MOTORPOWER_HIGH=450
;P2PP BIGBRAIN3D_MOTORPOWER_NORMAL=300
;P2PP BIGBRAIN3D_FAN_OFF_DELAY=2000
;P2PP BIGBRAIN3D_ENABLE
;P2PP BIGBRAIN3D_PRIME_BLOBS=2
;P2PP DO_NOT_GENERATE_M0
On the screen below you can see what i get from P2PP after generating g-code from pursaslicer. There are warnings but is completed - i guess in my case its ok?
I cannoct change ShortSplice because i have disabled option WipeTower in Printing Settings in Prusa Slicer (according to guide from instrucuion from BB3D).
Im not sure what about Short First Splice...
Do any of you had same problem? Or maybe i have done some stupid mistake?
Should I use some of previous version of PrusaSlicer or P2PP?
Is there any way to remove that warnings? (in my case i3 MK3 + MMU2s + BB3D)
