The CNC Jr. Mill now comes with the MasterSoftware which is operated with windows and is now in the market in place of the CNCPRO. The CNCPRO is very old now and out of the market. I am sure that if you contacted the makers of the CNC Jr. Mill, you can get an updated working driving system with updated software to upgrade your CNCPRO into a running, accurate CNC Jr. Mill. If you are an existing customer already I am sure they will cut you a deal and help you to run your CNC system like new. I would contact them directly.
