I had sever issues with PLA, went back to ABS, and nozzle broke. Replaced Nozzle by preheating the extruder, printed a lot with ABS, worked great aside from some pretty significant warp, which was expected, and a few lousy layers slightly off in the x and y, which happened to before and is expected because I haven’t gotten what I would consider an excellent print. Switched to PETG, had some stingy prints (what its known for) but then the print failed after about 15 layers of the print because the filament jammed (same issue I had with PLA.) Another print, much better, but made it to only an inch, part had a lower infil. All pats have had some shaky exteriors even at low speeds (50mm) meaning some layers aren’t perfectly on top of each other. Also, having done some machinery, and having done the paper trick for zeroing mills I know it works but it drives me nuts. I would like to first level the bed with a dial indicator then use a feeler gauge for the extruder. Side note I have an 18 dollar ceramic heater in a closet on high during all prints (printer is in the closet) also where I store the filament. Not a true enclosure, but it’s also probably 88-95 degrees in there.
What settings are you all using for PETG?
How do I stop the jamming? I was at 255deg and 100 bed temp, and I cleaned the knurled thing, and the tensioner is at 5mm.
Is it worth it to stop using Cura and start using Slicer?
What is the firm height number the Z is supposed to be off the bed?
Has anyone hit the bed with an IR or Laser Thermometer or FLIR to see where the hot/cool spots are?
What’s the best chemical to use to clean the bed? Alcohol or Acetone?
I read about calibrating Z-Step, is there a guide on that? Or a guide for adjusting any of the other preset factory settings to try and get this thing purring?
