Has denford ever made a machine with a tool height probing feature? I would love if this were a feature, as it would save a fair bit of time when using er collets! Something like this to test continuity: https://www.yrcnc.com/product/cnc-tool-touch-off-probe/

I have made one for the Triac PC that leaves the tool at the top of the probe. You then press the tool datum button on the tool offset page.
It runs within VR Milling5 using a "M" code i have added to my Mint file.

Blatter- that is exactly what I was hoping to find! Do you mind sharing the contents of the M code? I assume it goes to a safe Z height above the probe, rapids down until it touches, then lifts and drops at a fine feed? How did you hook in the sensor?

Hi MadeForThat

I can give you the mint code to add to your machines mint file. You will have to edit the code to use a spare input from your controller. I have added a Beckhoff Canbus module to my triac that has a 8 input module attached as well as 8 outputs.

I use M100 to position the tool at machine Z absolute zero for safety, then move to a predefined XY above the probe. Jog down to within 5mm above the probe, then run M101 which moves down in 0.2 inc until the switch is made then it backs off 0.5mm and then comes down in 0.01 steps untill the switch is made then the code stops. At that point i just hit the datum button on the tool offset table for the current tool

Hi, this sounds very useful. Are you able to share your code?

Thanks
