I have been using MACH4 for quite some time now and noticed that the "Current Feed Rate" DRO displays 90% of the commanded feed rate. This potential error has been present in all versions following 3233, industrial also.
I am not sure if this is just a DRO issue or if the machine is actually only running at 90%. In case you ask, yes the feed rate slider is set to 100% and also using the simulator as motion controller to eliminate any plugin issue.
In September of last year I submitted a support ticket regarding this issue with no response. There also doesn't appear to be any other posts pointing out this potential bug.
I don't know for certain but it seems like this could be an issue for anyone out there rigid tapping, assuming this isn't just a DRO issue, causing desync between spindle speed an feed.
Has anybody else noticed this and is it an actual issue? Curious because I have been reluctant to move from version 3233.
