Hello Mauri,
We really appreciate you taking the time to write this honest and good review, and of course, the time you had spent working with the HiCON Integra.
I'd like to clarify the current issue with the MPG as it also encompasses incremental/step jogging (or relative motion in general) for those who may be seeing a similar problem.
It appears that the current version of the Mach4 motion planner generates a trajectory that can be 1-2 counts off the intended target (this was verified in our testing when we checked the vectors that Mach4 was plotting). This is NOT present, however, with absolute position as it appears to be spot on to the very last count according to what we've seen with testing. This may or may not be a problem depending on the required level of precision, but it is clearly a concern for your application. As for the solution, we've brought up the problem with the Mach4 development team, and they're currently looking into it. We're still waiting on a response if the fix ought to be in Mach4, or if there is something that can be done from our plugin.
Thank you for your patience, and we'll upload the update once this issue gets resolved.
