Unboxed my CETUS today, printed very nice for the first few layers using the included pla. After about 15 mins or so I had a failure with the extruder where it had taken the PLA above its Tg. All the stepper motors were running very hot, between 40 and 65 degrees depending on the axis.
What are your views on this? Is there anything I can do to keep the motors cool? Or is a redesign of the extruder needed?
PLease check if the cooling fan on the extruder unit is working and nothing is blocking the wind from cooling the hotend.
The normal temperature of the extruder motor when printing PLA should below 60C.

Hi There Jason
The cooling fan is not functional when printing. Is there a wiring diagram I can follow to try and fix this?
Please Check if anything is blocking the fan, try replug the connector. see any wire is broken.
The fan is a 5V (0.2A) 4010 model (lenght 40mm, thickness 10mm). So if you have similar fan on hand, you could try to replace it and see what happens.
There was a bit of damage to the cooling fan which was blocking it from rotating. The debris from the crack has been removed and the fan is now functional.
no fan is being blocked on mine but the stepper motors are running VERY hot. anyone else have this?
The hot motor is normal, especially when it is printing.
