Could you tell us the exact alarm number?
I don't find any reference to "Invalid R in G0". I found "Invalid R in G02 or G03". If this is the alarm, the R value may be too small. It has to be > or = 1/2 the distance between the start and end points of the arc.
Another possibility is you're not getting a G0 or G1 output after a circular move.
I have been poking around with the machine and the MasterCam program for a while today, I noticed that all my offsets, ( G54 and TLO's ) have to be changed to get the machine to run,do you know what would cause this? I think MasterCam is doing it but I don't know why or how. thanks for any input and help. dean
Maybe MasterCam was posting to the centerline of the tool then a setting was changed and it's now posting to the tool radius line?
Are you trying to do cutter compensation in the Control rather than Computer? If you're trying to cut a .25" pocket radius and the cutter radius is greater than .25, I think it coughs out that error. Make sure that the cutter radius and wear values add up to less than the arc you're trying to cut.

If you are using M.C. X or newer there should be a Haas post processor that will not output "R" values, it will be "I" and "J" values, I would start there, but it doesn't make sense to me why you would get invalid "R" in a rapid move?
Greg I think you can stop calling yourself CNC nOOb, I give you permission, Robert
