Tap calculation error
I am trying to build a machine for our NTX3200 Mill/turn. So I copied the MT2000sz from the sample library which matches pretty close, but the machine was in MM. So I follow some others instructions here on converting to inch by starting a new inch project an pulling in the machine. Everything works great except for my tapping.
When I do a G84 tap cycle it give me an error saying that "feed per rev of .0013 does not match tap pitch"
But everything seems to be set up correct.
Code is:
M329 S320
G84 Z-.83 R-2.4 F10.0
Tap is defined as inch, 8-32 STI
I think it may still be calculating using MM, but I can't seem to find where to fix this.
My G-code processing says:
G84
- Feedmodeminute
Any help out there would be great.

Re: Tap calculation error
Change FeedModeMinute to FeedModeRevolution, you will need to change back to FeedModeMinute somewhere though.

Re: Tap calculation error
I already have it set to feedmodeminute under the G84 G-code processing.

Re: Tap calculation error
Set G84 to FeedModeRevolution and G80 to FeedModeMinute.

Re: Tap calculation error
Make sure the "UnitsInch" vs. "UnitsMetric" Macros are set in the control as needed. From the math it looks like it is reading F10. as 10mmpm not 10ipm.
We have UnitsInch set in the control events startup and G20/G21 defined to call these macros.
