Hi,

I recently finished a complete electronics and software upgrade to my Shopbot PRT 48 X 96 CNC Router using Mach3.  I replaced all the electronics with the exception of the Stepper Motors.  I am running a modified Mach3 2010 Screen Set.

I would be glad to share any information I have gathered during this process.  I have also put together a video on the retrofit process with highlights of all the hardware and software that I utilized in the process and associated costs.  If you would like a link to the video just send me a private message.
