Re: NPT Threads in Intercon - Workflow
The Centroid minor diameters are only valid for threading tools with the correct root flat or radius. If you are using a sharp V threading tool, you'll have to subtract another 0.108 * pitch from the minor diameter. You need to adjust the minor diameter in the thread details page and not the tool we...

Re: AcornSix - Zri Homing with linear scales
Just one point I'm sure you are aware of. The X-axis will not have an index pulse. The index pulse will be on whatever axis the SCALE is attached to.

Re: AcornSix - Zri Homing with linear scales
Those variables will only change when the encoder is sitting on the index mark. You will need to check the variable when the asterisk is showing on the PID screen.

Re: DRO display units
I haven't tried recently, but in the past there were issues with DRO units different than machine units.
AFAIK, there is still no way to programmatically change DRO and machine units. The only way is from the config screen

Re: C Axis Lathe Situation
Leave the negative numbers and the C-axis out for a moment and restate what Marc said. If my X0 is in the center of the part, X-2.0 to X2.0 would be a 4" move to the right, while X2.0 to X-2.0 would be a 4" move to the left. I think this is what you are expecting: G00 X-2.000 G01 X2.000 G0...

Re: C Axis Lathe Situation
C-23 to C-60 would move CCW.
C-60 to C-23 would be CW.
Same thing happens on Z.

Re: 3 Phase DC Power Supply
208V 3Ø to 120V 1Ø transformers are readily available. All you need is the Centroid "capboard".

Re: Can't add negative number to Low Range Spindle Speed RatioRatio
1) Thread milling doesn't use the encoder, so that is why there are no problems with that. 2) Tapping on the mill will work fine in high and back gear. Peck tapping will not work in either. 3) Even if you get the "back gear" worked out in the lathe software, lathe threading in back gear wi...

Re: Can't add negative number to Low Range Spindle Speed RatioRatio
Because that's exactly what it's designed to do. CNC12 changes the DAC output based on the gear ratio. The spindle encoder reads the SPINDLE speed and therefore should never need any gear ratio applied to it. It also does not, and SHOULD not, need to be "reversed" by a negative gear ratio....

Re: Can't add negative number to Low Range Spindle Speed RatioRatio
Spindle speed encoder output is supposed to be the actual spindle speed and does not get changed by the back gear ratio. As Keith pointed out earlier, if you have a Bridgeport style milling head and you attached the encoder to the top of the spindle, then you are not reading the actual spindle speed...
