@infiniteloop I have purchased the mahor v4 pellet extruder at 12v and 50w. I thought about this solution. I know the thermistor is a common replacement(although I won’t have to), but the guide for the extruder only specifies the dimensions of the heater, not a specific product. I’m pretty sure that the heater is no more than just a resistor and I can find a heater meant for 24v. The difficult part is finding the right dimensions. Otherwise, Maybe get a step down converter rated for my heater.

@infiniteloop I will buy a new heating cartridge. I just realized I didn’t even use thermal paste so I’m going to have to take apart the block anyway. Thank you for your help

@Phaedrux What about just getting a 12V power supply? I dont know if this will affect the torque of my motors, but I am using a 4.25:1 gearbox ratio to get better holding torque anyway.

It says v12 which is probably what I thought I was seeing with voltage to the motor. It is too late to return my extruder so I will probably just get a 12v power supply. Unless there is some other way to regulate the voltage?

I have a switching power supply that I can change the potentiometer to get down to 21.6V but this probably is not enough.

I purchased a 12v 50w extruder unknowingly while I have a 24V 350W power supply. I know for fans on a Duet 3 6HC mainboard, there is an internal voltage regulator that will prevent damage to the fans. Will this same regulator protect the heater and thermistor of my extruder? I have tested stepper motors and duet web control tells me that I get 24V in, but only 12V go to the stepper motors. Is that discrepancy because of the internal regulator? If so, Does the voltage regulator protect the out1-3 or temp0-3 ports? If not, would the external regulator circuit for lower rated volt fans on boards before duet 3 work the same for regulating the out and temp ports or is there something else I should do?
