Hello. I completed building the cheap microscope V7 and it works, but the Z axis motor becomes too hot to touch (so in excess of 50C) within 10 minutes. Since the 'scope is PLA with a glass temperature of 50C this is not safe.
I have seem a couple of old threads on this here, from 2020, but nothing recent, and no solutions. There is some suggestion that the motors remain energised after moves. In this instrument, this makes no sense as the mechanism is stiff and will not move without the motors, so there is no need to holding torque.
I’m driving with a Sangaboard v.05. The mechanism is easy to move with a finger when the motor is disconnected, so it’s not an excessive fricion issue. I’ve swapped the motor for another and the problem remains so its not the motor either.
Does anyone else see this?
More importantly, does anyone know how to solve it?
If not, can I obtain the source and maybe edit and recompile it?
Thanks
