Mach 3 / Mach 4 support for ISEL UPMV 4/12 cards
« on: January 31, 2020, 04:15:14 PM »
Would anyone know if Mach 3/4 supports the ISEL UPMV 4/12 motion controller cards? They are older ISA cards
Or if anyone knows how to go about integrating support for it?

many thanks in advance.

to my knowledge neither Mach3 nor Mach4 will drive the ISEL UPMV 4/12 motion controller.

Mach3/4 are Gcode interpreters and trajectory planners. The trajectory planner produces PVT (Position,Veloctiy over Time)
numeric data in 1ms time slices. The motion controller, and for this discussion Mach3's parallel port engine is a motion controller,
takes that numeric data and converts it to pulse streams for various motors etc.

If the manufacturer of the ISEL card produces a plugin that converts Machs PVT data to trajectory input acceptable to
the ISEL then it would work. Does ISEL have such a plugin? I suspect not. Its not that Mach COULDN'T drive the ISEL
but rather ISEL has provided no means to adapt their product to Machs trajectory planner.
