I am setting up a RPi CNC using external stepper drivers (DQ542) on a large format CNC (1300 x 1000) after loosing two PCs running LinuxCNC in the last 12 months - psu's died - we live on the beach so salt laden air is an issue.
I now have a sealed PSU for the RPi but was wondering if other users have installed cooling fans for the RPi + hat? The stepper drivers are mounted remotely so no heat contribution from them.
Ideally I would like to put the RPi CNC in a sealed box but realise that may be asking for overheating problems.
