New Member, a little experience with 'toy CNC' but got a bigger baby now :-) !!

I'd guess those stepper drivers date from the 90s, so there's every chance nobody remaining at Infotek who actually know anything about that age of machine.

I'd personally replace all the electronics and motors with more modern bits, as even more more modern steppers will give you a good boost in performance.
As for motion controller and software, take your pick.
I'd personally not use Mach 3 now, but if you have experience with it, it's as good a reason as any to use it.

Hello again m_c;
All motors and drives now tested and working OK. I'm hoping not to spend much as it is for hobby use and I couldn't justify splashing out on new motors or controllers unless I really had to.
Started disassembling the machine and cleaning rust off the lead screws.
Hoping to get it all back together over the weekend if the weather is OK.
