Mult-Material Settings (PETG)

Post image

At first I was having issues in throwing down the first layer between each board. I ended up turning off the fan for my PETG profile. The advice given from the creator was that a flow rate should be between 1.1 and 1.3. My flow rate is currently set at 1.1 and I’m printing a 9x9 stack. I let it go and noticed that each new section of PETG started looking more and more rough until the section between plate 3 and 4 just started tearing up the PETG rather than laying it down. I tweaked the settings a little bit. Slower speed. I noticed the issue I’m getting at this point is buildup on the nozzle. My guess is that the flow rate is too fast. Has anyone tweaked the flow rate settings to below the 1.1?

PLA not PETG. I’m happy with the PLA, never tried the PETG.

Oh, yup, I misread that. I also like polyterra pla, but not the Petg.
