Nice one Tweaks - That pcb is as dinky as a dinky thing with a first class honours degree in dinky.

Thanks Ian.  ;D

Thank you also for your work, a while back, relating to the G31 command and Mach’s interpretation of how variations in multiple contact resets the Var (2002) etc.
This was influential in my design and helped a lot.

Tweakie.

HIYA Tweaks , Have you thought about putting in an overtravel switch so that in cause the G31 goes wacky the OT switch will trip as a Limit and save the machine/tool/probe/part ??

Just a thought, (;-)TP

Hi Terry,

Must admit that I had not thought about that - damn good idea, thanks.  ;)

It's a very poor video (this is an area in which I really must improve my skills) but shows its operation. http://www.graytel.talktalk.net/probe.wmv

What the yellow piece of material for?

Another fine project my friend
But four place decimal in metric are your running servos with 8000+ encoder pluses?

That is a great idea Terry, wish I had them for tool breakage detection switches. ;-]

That is the most important part Sam - It's the work piece which subsequently gets engraved  ;)

 ;D ;D ;D

No way, my theoretical resolution is 3 microns but so long as it does the job I leave as many of the Mach settings as untouched as I can  ;)

theoretical resolution is 3 microns
so your actual resolution and repeatability is?
Not many industrial machines can give me that resolution and repeatably.
I very happy with 10 microns for most jobs. So many variables.
