I don't think you want it to trigger an estop as positioning is lost when an estop is triggered. There is another pin for probing, pin 15 in my setup.

I'm not the one whining about it not working perfectly. Life is a series of workarounds.

Well I suppose you could always roll up your sleeves and get programming to fix it. Since there is no Windows based competitior for Mach3, having comp pretty close to fully functional is a better option than we've had to date.

Seems to me that specifying a cutter diameter .0001" undersize (even if the cutter is onsize) will result in 50 millionths error in the part whilst allowing the comp path to run. My mill can't split .00005", can yours?

I've seen alot of references to members running 3.041 with no more complaints than on other versions. I'll take the plunge.

General Mach Discussion / Re: Cannot do single point threading. What's wrong?

« on: November 11, 2008, 03:17:29 PM »

"Slot" is a term I expect to be associated with a toolchanger on a mill. Never heard it used in that context before. Simpson36 stated that Mach is not controlling the spindle speed, and that's what I read. Mach needs to now the angular position of the spindle as well as z axis position to single point thread. If it cannot control but can monitor the spindle speed then it must adjust the axis feedrate to compensate for any mismatch in spindle speed (and the resulting angular mis-positioning). Sorry to muddy the waters.

My use of the work "expect" was related to what appeared to be a misunderstanding of the technology on your part... as it turns out I'm the one who has no idea what I'm talking about.

Well provided the spindle speed is accurate, I can see where a starting point would be sufficient for single point. I did not get from the OPs post that the controller received angular feedback from the spindle. Spindle speed and angular control obviously has nothing to do with thread milling as this is just helical interpolation using 3 controlled axes, and Mach certainly has control of those.

If Mach is not controlling the spindle then how do you expect Mach to syncronize the spindle in order to pick up the thread? The control needs to know the z position as well as rotational position of the spindle to repeat with a single point tool.

General Mach Discussion / What version to run

« on: November 11, 2008, 07:02:27 AM »

I am currently running Mach3 R2.63. Is there any benefit to running the development version R3.041? Any glaring issues I need to look out for? Is 3.041 nearing certification as a production release?

General Mach Discussion / Re: how to create own treatment for mach unknown code f.ex. G27, G25?

« on: November 09, 2008, 03:57:22 PM »

Seems to me you could have the postprocessor create the code then use a text editor like notepad to find/replace m3 with g27 (or whatever you need to substitute).
