thats the problem
Will setting up the tools in tool table with specs of cutter position and radius of the tip do the trick? With calling out the right tool and a right G command?

Is that tool position stuff relative, and when adding angles, the way they appear on screen as animation, is it also important for proper tool setup?
And I still have no clue on how to set a left hand turning tool in touch off (x seems easy but how do you set z, cutting edge is oposite to touch off surface).
Also, it looks like that the postprocessor I am using isnt suitable for emc2. Thats why I get those wrong dimensions... There are sevearal posts here on that matter, but I didnt find one that has cutter compensation efective (in explanation)

No. It could be used in the future to detect gouging (for example) but I know of no plans to do so.Is that tool position stuff relative, and when adding angles, the way they appear on screen as animation, is it also important for proper tool setup?
You would "touch off" the cutting surface. Probably by measuring where a left-hand faced surface ended up.And I still have no clue on how to set a left hand turning tool in touch off (x seems easy but how do you set z, cutting edge is oposite to touch off surface).
I have very rarely used it. It has no effect on normal turning and facing operations, and I have almost never been _that_ worried about a radiused surface being exactly correct.Also, it looks like that the postprocessor I am using isnt suitable for emc2. Thats why I get those wrong dimensions... There are sevearal posts here on that matter, but I didnt find one that has cutter compensation efective (in explanation)
It is likely that your post-procesor would do tool compensation in the postprocessor rather than in the interpreter anyway. does the CAM system ask for details about tool radius?

I am not so worried about surface being correct, but to keep the dimesnions needed correct. Plus to this, I ve found today that while making a forward movement on x, I loose 0.2 mm per movement. When it goes back, it lands where its supposed to be. When I loose the gib screws, that amount reduces. Any idea how to deal with this (and not have a chatter and slide "chewing" problem).
CAM system does ask for details about tool radius, tool shape etc. So if a cam is writing down the compensation in the g code, I shouldnt be worried about it in trying to set that up in tool table (assigning a right radius of the tool in there)

And also, any idea can I hook up the existing interrupter to the BOB
I would use the Z and A limits, probably. And connect the X limit to X limit and Z limit to Y limit. Because it's all just uncommitted IO pins really.

And after the stepconf setup, I ll just have to modify the hal as per
linuxcnc.org/docs/html/examples/spindle.html
?
Thanks!
