Thanks Gary & Marty for the quick response. Will try and report back as soon as acorn and the DMM servos are installed!

I wanted first of all to say thanks to Scott for setting this up,
it seems to work great I have one issue it seems that when the tool is going down to the
touch off plate it could be a little slower on my machine, I have slowed the jog rate
on the machine and this slowed the z axis when touching off but I was wondering
how to slow it down in the macro if that is possible.

also was wondering if there is a macro for a corner finder.
it is basically a small square with a pocket in the corner and when the macro was run
it would zero the x and y axis on the corner of the sheet to set a start point for maching
an item that was critical on starting at the x0 y0 of the material, I have looked here
but have not seen one maybe no one else uses one?
kinda a router thing...
thank you,
Charlie

I'm wanting to add some functionality to the tool setting macro. Something like this.

• Start job
• Go to G28
• Prompt to insert first tool
• Probe down to moveable touchoff plate that's on top of workpiece. This sets Z0 at top of material.
• Go to fixed plate position, probe down to fixed plate. Store difference between moveable plate and fixed plate.
• When M6 comes up for tool 2, go to G28
• Prompt to enter tool 2
• Go to fixed plate position
• Probe down to fixed plate.
• Set new Z zero using the difference stored before.

Thoughts? How on earth do I go about making this happen? It would save me a TON of time.. This is on a router..

Did you read the very first message in this thread? It works remarkably well and uses any plate of a known thickness. It should do want you are asking. Try it.

Of course I did. I’ve used the macro with the moveable probe. What I’m proposing is not covered in the first post of this thread... :/

What I’m wanting to do adds a whole other layer of functionality, especially in programs with multiple tools. I’m just not sure how to get this going.

Slodat...
"Thoughts?"

My thoughts are: 1) You are over complicating the process 2) Your process requires 2 different actions when a tool change is called 3) The stored switch height (offset) is used thousands of times a day and works very well and saves a step over your process 4) I show that process in this video, second section: (about 1:30 in) https://youtu.be/xqTpEXHOWPw
I do have an unshown section that writes the switch offset.

"How on earth do I go about making this happen?"

Copying sections of existing macros that perform the actions you desire, build a custom macro and test it

"It would save me a TON of time.. This is on a router."

If you simply went with a switch that was calibrated to the spoilboard, you would save 2 to 3 tons of time, gain accuracy due to not using a conductive switch and eliminate at least one step in the process for each file

ahhh!! Gary! Thank you! This is even better! Care to share details on your switch and associated macros?

Tried setup #2 and have a small (I hope) problem. I have somehow ended up with COM and Ground tied together. Not sure where, guess I should figure that out.

So, anyway, that means as soon as I clip the alligator clip to the bit, IN7 goes high. Is there an other way to go about this, or do I just need to take some time and make COM and GND separate?

Thanks,
Wally

Duh! Don't use the alligator clip. Even easier!

Let's just say I had a rough weekend and leave it at that, OK?

Thanks,
Wally

Just wanted to say thank you to all who helped - it all works great!

Have fun with your machines,
Stefan
