6.2.5 Firmware for Original Prusa XL
Summary
- Fixed hangs during fast consecutive toolchanges
This is the stable release of firmware 6.2.5 for Original Prusa XL.
Fixed hangs during fast consecutive toolchanges
We addressed an issue where the printer could hang for several seconds during quick, consecutive tool changes.
The problem was traced to the print fan going from full power to off upon tool parking. This destabilized the nozzle PID regulator, which in turn made the M109 “Wait for hotend temperature” G-code wait until the temperature stabilized again if the tool was picked too soon after being parked.
We have calibrated the PID regulator so that it would not destabilize due to print fan speed changes.
