One thing I noticed is when I used just the shard of mirror, the temperature quickly climbed that last 10 degrees. The temperature sensor was no longer under the mirror. The mirror must be radiating heat faster than the plain PCB board? Anybody have any science on this?
I put 2 pieces of tape down to hold some heat around the part as the printer is out in the open in my cold basement. I got a lot less lifting printing straight to glass with a bit of hairspray than I expected.
Broken bits of my print surface laying on the edge of the aquarium next to my printer. It’s a cheap IKEA mirror tile, so I will cut another and edge it this time. I also will adjust the sensor that the glass broke over.
Printing on a shard of my broken bed. The blue tape is to create a warm pocket of air to reduce ABS curl.
This part lifted surprisingly little for it’s shape & printing in an open basement. Less than a mm lift that worked back less than a cm. First print with the ABS after switching from PLA, so I am sure the first few layers where contaminated with PLA and I didn’t have the temps tuned right for clean printing.
