5.02 Cooling Fan Speed Not Updating
Posted: Tue Feb 28, 2023 2:58 pm
Slightly modified TronXY X5SA printer with a BTT 1.4T board and Hemera extruder. I'm trying to turn off the fan for the first few layers, to get better adhesion, so I set fan speed of zero for the first layer and then change the speed according to the filament I'm using. I've never had a problem until 5.02. What happens is that gcode turns on the fan full (M106 S255 P1) before running the starting script, and then doesn't do anything else. It's the only M106 command in the whole gcode, so there's no change in the fan speed. In the earlier versions I would turn off the fan in the starting script so I wouldn't have the cooling fan on while heating up the nozzle. In this version, if I do this, the fan never comes back on. Any suggestions?
