Hi everyone,

I recently built and installed an MX4660-based machine in my garage. I used the CNCRouterParts DIY NEMA 23 kit for the electronics which includes the necessary power supply, MX4660 driver, motors, and cables. My DIY enclosure does have a vent by the fan of the power supply, but I notice that the enclosure is getting very warm, especially where the MX4660 sits. Do I need active cooling for this driver or will it be OK without any? I don't see anywhere to mount a heatsink to the driver and I guess my only other option would be to add another little fan.

What do you think?

Thanks!
