I am a teacher at a middle school and we have a TAZ5. We replaced the hot end with a flexydually a bit ago. We’ve only done a little bit of printing with it, and while trying out some PETG the other day, I realized that the fans on the hot end weren’t running. I was using simplify3d and when I open the machine control panel window, I have found that when I turn the fan speed up, it only goes on once I set it at 100%. Additionally, at 100% the hotend also starts dropping in temperature. Anything less than turned up all the way causes the fan to stop running. I tried incrementally adjusting the fan speed using m106 and it seems as though anything less than 98% isn’t turning it on.
For what it’s worth, the LCD display on the TAZ5 is showing the speed at different %'s. I’ve also tried printing/adjusting the fan speed using CURA and I am finding the same thing.
I’ve searched the forums a bit, but haven’t found anyone with the same problem.
Thanks in advance for any help.
