I recently purchased a Geeetech i3 printer on Amazon and have been having trouble getting it to operate due to a MaxTemp error.
When I turn on the printer - or plug it into my computer - the fans turn on but the extruder will not heat up due to the MaxTemp error.
I have purchased a replacement thermistor with the same result.
There was once that it did heat while I was doing tests and fixes on the z-axis movement, but both before and after that it regularly (always) triggers the error immediately.
Are there settings I can change to attempt to fix? Or is it a problem with the motherboard?
Thanks
