I am printing small mechanical pieces in ABS:
- 100 ºC bed temperature
- 70 ºC Room temperature
- 250 ºC nozzle temperature
- 0.4 mm nozzle, at 0.15 mm per layer.
- 100.8 % scale to compensate ABS dimensional innacuracy.
The first layer is printed correctly, but later, corners warp and first 10 mm get deformed (See images).
How do I solve this? Unfortunately, I cannot increase room temperature over 70 ºC
Here is a picture while printing, we can see that the edges get warped even far over the first layer. (Sorry, the picture quality is not so good):
