My favoured way of setting tool offsets is to zero the z axis on a flat surface with the Haimer (tool 50) Then I use a home made setter which has a height of 31mm. The thimble is sprung loaded and connected to a cheap battery light. As soon as the cutter touch's, 3 bright LED lights comes on. I enter the 31mm offset in the offsets page. and move on the next tool. This works for me.

Hi John - Thats an interesting set up. In what way does your setters electrical switch work . Is it a plunger type ? Did you make that also? Cliff

Hi Cliff. Yes it has a sprung loaded plunger Drawing should be self explanatory. Metal plate added to torch base to complete circuit.Attachment 444366

How is overtravel handled?

[John Roberts]

There is about 3mm of over travel which I find is plenty when manually touching off. As soon as contact is made with the tool the light comes on. Have used it hundreds of times and never bottomed the plunger out.
