Report cnc breakoutbord troubleshoot in Projects Q/A Posted June 23, 2017 Hi all, I'm new here!. I created a pcb board of this schematics: http://www.electronics-lab.com/project/optically-isolated-lpt-breakout-board-for-cnc-routers/ and it did not work and I'm trying to find out which part went wrong. I need to ask first what should the VDD voltage be?
