This week I work on fixing my PCB and this is a new version of my PCB. I have fix some wiring and added another 100f 50v capacitor. I have tried one driver yet which seem to be working find, another driver is dead so I'm have to replace that. I have also added 12v output which will run an cooling fan.
I also worked on the pen plotter. I unassembled the base and the rod. This are the new rod which I just put in to measure the size. I'm going to work on building new base for this using acrylic.
