Title: Mach3 Auto Tool Zero
Post by: irondesk40 on March 19, 2019, 08:52:46 AM
New to this and using this forum to try and learn more and hopefully someone can help with the following.
Have a Pro48 unit purchased from CNCrouterparts and it is a awesome unit and have went to directions and have got the machine to run. Have followed youtube videos and went through the Auto Tool Zero steps using the touch probe unit we purchased from Cncrouterparts to set the x,y, and z axis zero reference as to where to acutally start on our work table and it works perfect. What i am trying to figure out is after we go through this procudure to set the Auto Tool Zero is there a way to save that permanently so that if we turn the machine off or turn the PC off we do not have to go through that procedure everytime we turn them off.

It's hard to say without knowing exactly what your procedure is.
You would typically always want to zero your tool every time.

You could write or modify a macro to automate it.
What you would probably want to do is permanently mount your touch plate somewhere out of the way.
Surface your spoilboard, and set Z zero.
Then have a macro probe to the touch plate, and store it's location in machine coordinates relative to your spoilboard z zero.
Then, when you turn on the machine, you home it, and auto zero to the plate.
in your cam, you'd always set Z zero to the spoilboard, or bottom  of your part.

Offset can be saved permanently at G59.253
and
If Copy G54 from G59.253 on startup is ticked, you have recovered G54 offset on startup.
Be careful with the z axis though, since material surface height and tool length may have to be different.
