MK4S Upgrade -> HF Nozzle -> Organic Suports = Fail.
I upgraded to the MK4S recently. Resliced a model I have recently been printing, between 10 - 12 hour print, mostly printing the organic supports.
Sadly, after this upgrade and re-slicing the model for HF, the printer is not able to complete the print job. 2 times it has failed at the same place, that is printing the organic support material, one of the 'trees' (?) lose adhesion at the bed, fall over and cause catastrophic failure of the others.
I put the old brass nozzle back in, use my old model and I was able to print without issue.
Anyone from Prusa interested in seeing what the difference is between organic supports on HF nozzle vs a non-HF nozzle?
I can share the GCODE, it is rather large.
RE: MK4S Upgrade -> HF Nozzle -> Organic Suports = Fail.
Try washing your print sheet with soap and water. Make sure your using a HF filament profile.
You might need to increase nozzle temperature by 10 degrees as the faster speeds with the HF printer profiles are more likely to underextrude.
Can you post a picture of your failed print m
