@chrishamm, thanks for the information, really helpful.

I had some follow up questions:

In addition to the 5x stepper motor drivers on the Duet 3 Mini 5+ WiFi, I’ll be using a Duet 3 EB mini 2+ for one extra motor.
I’ll use 6 motors in total: 1x X motor, 2x Y motors, 1x Z motor and 2x extruder motors.

1. For an ambient operating temperature of 60degC what would be the maximum current you would recommend configuring the motors too before using active cooling?

2. Would you recommend different maximum currents for the different X,Y,Z & Extruder motors at 60degC ambient temperature?

3. What is the highest recommended calibrated MCU temperature (degC) during printer operation before active cooling is recommended?

Thanks,

Hi Duet 3D technical team,

Can you please let me know the maximum recommended ambient temperature (degC) for operating the Duet 3 Mini 5+ WiFi before active cooling is required.

I’m currently designing a 3D printer

Thanks
