Title: Mach3 can only "Auto-tool zero" once per session
Post by: JoonasM on January 29, 2021, 04:06:03 AM

Hello

Since the beginning of me CNC'ing with Mach3 it has only let me automatically zero my tools only once per session (with expections that I have not ran a program before). Every time I want to re-zero a tool, it goes to the probe and stops wayyyyyy above the probe itself and sets the Z value to something like -25.0000, which normally for me should stay in the range of -150.0000 to -180.0000. So everytime I want to zero a new tool, I have to restart Mach3, home all the axises and then auto tool zero it. Is there a way to avoid that?

Show us your script, and we will see.

-Operator -> Edit button script

-Auto tool Zero button should blink now

-click on button -> Editor window Comes up

-copy and paste code into a file

-post file

Show us your script, and we will see.

If you mean the "'Auto-tool zero" script then here it is. There are some Estonian phrases there, but it doesn't really affect anything. They're rather informative.

Looks like something is missing at the begin of script.

there is a End if without an IF ... Then before?

Yup something is indeed missing, I let the mouse go a bit too early. Here is the full script.

how far is your distance from Zhome to probepoint?

how far is your distance from Zhome to probepoint?

It depends on what bit I have on the spindle, but it ranges from 150 to 180mm. None of them go over 200 and the Z stops wayyyyyyy above the probe when I try to auto-tool zero back to back.

For example, at the moment I have a 6mm end mill, the Z value is -160.5828something. If I would try to auto-tool zero again (I have run a few gCodes through in this session), it would change the value to -25.00000.

Thanks a lot! Can you try and explain to me what could have been the issue here? I'll try it and will let you know if it works or not! Thank you.

basicly i removed the G91 from the G31 code line, had some Problems by using G90/91 in same line
with G31 in the past.
