CHANGES to CNC PROCESSOR

New - Automatic Transformation of 2031 MODBUS Commands to 2032

The 2032 command is a new type of incremental move command that instructs the controller to move the axis a relative motion from its current position. (2031 moves from the goal position, which may not be the current position)

This resolves an issue with direct axes jogging where an axis stops moving at a hard-stop, but the controller continues to track the position as if the axis is still moving. MOBUS command 2032 overcomes this potential problem.

Only controls upgraded by SMT technicians can use the 2032 command. If this feature is enabled before the control firmware is updated the incremental or relative motion will not work properly.

The transformation is enabled and setup in the CNCProcessor.cfg file in a Modbus section that looks like this:

[Modbus]
Transform 2031 Enabled= 1
Transformed 2031= 2032

The text in these fields before the "=" must appear exactly as shown above for the values to take effect in CNC Processor.
