I received my A250 at the end of October.
I used the calibration card that came with it to adjust the clearances.
After printing a few times, the filament stuck to the sheet and I could not remove it.
My mistake at that time was that I held the printing sheet with my bare hands and curved it.
The filament is no longer fixed on the printing bed due to hand grease.
I was so confused that I made several clearance adjustments and shortened the distance even more.
Skirts and blimps cannot be used in this condition.
This led me to wonder if the adjustment using the calibration card was a mistake in the first place.
On my previous 3D printer (Raise3D), I used a 0.2mm metal clearance gauge.
I used this to adjust the clearance of the SM2.
I printed with a clearance of 0.2mm between the print nozzle and the bed, a stacking pitch of 0.2mm, and a print speed of 12mm/s for the initial layer with no problems at all.
The filaments are PLA and ABS.
ABS is more prone to warping than the previous (BuildTak), but with some care, it can be done.
Sometimes the filament cannot be fixed, but cleaning it with IPA will solve the problem.
The first thing to do if the filament does not settle is to clean it.
Also, I’m using 11x11 for auto calibration.
Thanks to brent113 for the tip.
I am printing almost every day.
