Anyone converted a Denford VMC 1300 Pro to Mach or LinuxCNC?

Thanks for the reply m_c. I'm thinking Mach 3 (or 4) or LinuxCNC to drive the VMC via a parallel connection to the NextStep "bottom board".

This is my reference data sets acquired from the web so far:

documenting step and direction signals to the Baldor "bottom-board" stepper drives

Second post in the thread has the Pro diagrams - the Pro uses a Baldor Microflex servo control for the spindle drive

this servo control is a real beauty, I've no idea what they cost


Really detailed and well illustrated (with videos) blog by Jay Summet about conversion of Micromill 2000 to Mach 3, a series of 4 posts, starting with X, Y, Z and concluding with spindle speed

Jay's conversion to drive the spindle motor controller via a PWM signal involves some board mods that I'm reluctant to do, so will look for add-on board to get the 10V analogue drive for the spindle speed (I still have to check that the MicroFlex spindle is controlled in this way)


Looking on diycnc.co.uk for suitable BoB and step to 10V converter
