Hi Rowan,

I have upgraded my VMC 190 machine recently (still bits to do), but I basically used a Ethernet smoothstepper, a PMDX 126 Breakout board and a PMDX 107 speed controller. Luckily all these boards plug into each other which makes it really compact.

My original intention was to try to retain the stepper drives (GS-D200S), and I did have it working to a fashion by patching into the board that these were mounted on but you need to be careful as this has 240V input. I have recently bought 3 off leadshine stepper drives and I installed them. The machine is now working alot better. I retained the original stepper motors and the psu I have also left the original spindle relay in situ, this I believe allows for spindle reverse.

I still have to work out how to get the tool changer to work and there is a spindle sensor which I need to investigate as not sure how I can patch this into my PMDX-126.


Hope this is of some help.


Regards

Steve
