Re: Help: Stuck TOO well to PEI+MIC6!

Next time I experiment with this filament, I plan to put down some kapton over the PEI to give me a disposable build surface until I dial in the process. Maybe this filament will work OK with lower bed temperature... or maybe it just sticks too aggressively to PEI to use it on that kind of surface. ...

Re: Help: Stuck TOO well to PEI+MIC6!

I think I've found a technique that works. Heating the build plate to 110ºC makes the filament fairly soft. I have sliced off most of the mass with a sharp razor. It appears that I can burnish off the remainder with an electric drafting eraser. Periodic re-heating of the plate is necessary, and care...

Re: MIC6 preorder number 3

I arrived in this thread a bit late, but I'd like to order one with PEI if one is available after first satisfying everybody who got here in a timely manner. I'd like to have a spare plate on hand after a recent printing disaster.

Re: Help: Stuck TOO well to PEI+MIC6!

Thanks for the suggestions! Maybe I'll try warming the bed to a higher than normal temp to see if that helps before I go to work with a razor blade. Maybe I should look into getting another PEI+MIC6 plate to keep on hand as a backup.

Help: Stuck TOO well to PEI+MIC6!

I have one of the fantastic MIC6 with pre-applied PEI from a previous production run by Insta. It sat idle for a long time, and I finally got around to installing it a few weeks ago. I had been generally printing PLA with the extruder at 200ºC and the bed at 60ºC. I had trouble with corners peeling ...

Re: MIC6 preorder number 2

I want whatever the optimal build surface is for PLA and PETG. ;)

Re: Extrusion calibration

Thanks! Ok, I'll finesse things a bit more in single extrusion land as a learning exercise, and I'll try printing some non-PLA. But it sounds like it's almost time for me to install that dual extrusion upgrade kit.

Re: Extrusion calibration

These photos aren't fantastic, but I hope they're good enough for you M2 experts to tell me if I'm on the right track with my extrusion calibration. I made this little 60mm square test piece to work with extrusion of flat horizontal surfaces over support. Extrusion multiplier is 0.9, temperature is ...

Re: Extrusion calibration

Got it. I used to print at 190C with my previous printer, but its temperature calibration was so poor (I measured a 10C difference between setpoint and a thermocouple shoved down the extruder path) that I don't know what the actual extrusion temperature was under normal operating conditions.
