Ok so store goes bought vmc at auction of which owner died etc... under looking at the machine it was obvious that someone had been looking into issue that im having, there was a password on machine of which someone on here was kind enough to help with and that got me rolling... at this point in time the machine looks to size up to a good machine, I have replaced cpu from old dx32 mb to p3 650 MHz with 500mb ram and new hardrive etc all is good on the home front stability looks good and no crashing... the issue I have now is spindle will fault out and not upto speed in time because of parameters on cpu and tuning in drive etc... feedback loops are all messed up... my thing is why worry about out dated dos. I like mach 3 and abilities It is expandable and can become true closed loop as well but is much newer and user friendly!!! im looking to integrate a controller for simodrive 611 and analog drives and all feedback etc, I have lots of candidates and fair pricing... as of now im going to still mess around with feedback and get original to work and leave as much intact as possible, but I want to tye in a new system to work in parallel with old, anybody have any feedback on ideas... I want to make a separate bus with the old and power down the old but tye into it with new as to use old as backup....
