General Mach Discussion / Re: Tool Offset Macro...

Yes, the Enc module counts whether Mach is In or Out of Reset, so no probs there, obviously it is Out of Reset you will want..
The DRO is purely counts and you need a Brain or Macropump to scale that to your correct distance (ie setting steps per unit) and then you can write that to a user DRO or even the Encoder DRO in Mach, think that is what I use.
You will also need to rewire things a wee bit as you do not want the Index from the encoder going into the Enc module as that is what sets the DRO to zero and as such will do each revolution. CS-Lab said they would look into giving you an option to manually set zero but don't think they ever did. I got round it by simply having the Index on the Enc module pulsed from an output via a screen button.
Looking good, just make sure the angle part that touches the tool is flat and a true 90 degrees or you may get a variance from small to large dia tool. That is the reason my tool holder slides, I can set it so the tip of any size cutter is on a specific (machined) part of the setter.
