Hi there, there are some Threads about the 0.2 Blob issue on Reddit but i canot find anything here. Since it should be a Firmware/Slicer issue. has anyone found a workaround for those ?
Problem is the H2D creates huge Blobs while Flushing so it is just a matter of time till the Rubber gets flushed with it if u dont Babysit.
I was going to create a thread on this issue. Thanks.
I looked at the gcode to maybe modify the initial purge process but never came up with anything that worked.
How familiar are you with gcode? I’m wanting to do the same to reduce initial purging, but am not having any luck either.
Not very familiar. I did customize the filament end gcode for my x1c to run the aux and exhaust fan for ABS after printing completed until the bed had cooled down to 50 degrees.
My most complicated gcode ever:
M104 S0 ; turn off hotend
G1 X65 Y245 F12000 ; move to safe pos
M106 P3 S179 ; exhaust fan to 70%
M106 P2 S255 ; Aux fan to 100%
M190 R50 ; wait for bed to cool to 50
M106 P3 S0 ; exhaust fan off
M106 P2 S0 ; Aux fan off
It’s pretty basic but it did work.
The gcode I was seeing for H2D was looking above my skill level. I don’t think I have time to fix it. It’s obviously a bug and Bambu Lab will hopefully fix soon.
I’m experiencing the exact same problem here with the .2mm nozzle creating huge blobs during “Changing Filament” on print startup. Can anyone from Bambu support confirm whether this is being addressed?
Would love to know this as well! The printer prints like a dream in most aspects, only issue I have is when using the .2 mm nozzle creating blobs. Even had some filament stuck on the nozzle itself (couldn’t change the nozzle because of melted plastic).
It seems to me that all you have to do is increase the amount of times where the filament gets launched towards the poop chute.
