Hi everyone. I am new to CNC plasma cutting and our shop has inherited a plasma table running on DeskCNC . Attached is a board the DESKCNC Serial board is connected to before output to 3 motors. Can anyone help in identifying the board. No info printed on it. The colored ribbon comes from the Desckcnc board and is soldered to pins on the parallel port cable which plugs into board in picture. looking for schematic on to what this board is doing?(looks like I can upgrade to a simpler hookup but need to know what is going on here first) The red and black wire on the right (G,+5) go to a relay board where the output goes to the plug which goes to the plasma gun (assuming this starts the plasma torch). The wires on left are from power supply and output to a fan which is cooling the electrical enclosure.Also any info out there on the DeskCNC board with serial input. Cant find schematic on this to see pin outs etc.
Thanks in advance for any help
Solved...May 27....these are a XS-3525/8S-3 driver board with a deskcnc controller.
