I found one easy solution for stick ABS may be some need this informtion.
Take any medicine in spray (I use almost empty bottle from hydrogen peroxide)
Empty bottle : )
Put a little acetone inside and try to spray it. Wait about 5 or 10 minutes and try to spray again. My one made from PETT and metall so nothing happend and work perfectly.
Put a half (or more) acetone and drop some ABS inside.
Go to sleep : )
Use spray on hot bed. And brim (10 lines) for stick on clear glass.
Now I need about 2-5 second for start printing. And about 10 seconds between printings.
good idea, just make sure you only spray it on the bed and not on any other parts of the printer. I use a paint brush to apply ABS juice. Works well on cold bed, not so good on hot bed as it builds bubbles.
If you use clips to fix the glass/mirror, you could exchange it with a prepared one while the bed is hot. This way it should heat up fast and it’s safer to apply the abs juice outside the printer.
