I used Original Prusa i3 MK2 to print ABS parts.
- All printed ABS parts
- Replaced 12 balls
- Latest firmware: ReprapFirmware dc42 1.17d , DuetWebControl 1.14
Duet Web Control 1.14
It now monitors CPU temperature. During print the CPU temperature stayes around 30 degrees Celsius. I wouldn’t install 5V fan for cooling which had been major source of noise.
