Review on SainSmart Genmitsu 3018 PROVer Machine Controller by Bradley Wacks

When I received the PCB there was a blue plexiglass screen on the front panel with a heatsink cutout with a heatsink cutout. The plexiglass cutout was smaller than the heatsink and was tightened by the manufacturer to stress the board. I trimmed the plexiglass screen to reduce the stress on the circuit board. Installation complete, drivers installed. Then I run a job with Lightburn software and everything works fine. I run the same job again and the board stops working.
