Hello All,
The newbie once again has a question for all you pros out there.
In setting up the bit height I use a .375 inch roller bearing. I will jog Z up and down until the bearing will just roll under the bit with a very slight amount of resistance and then zero out the axis followed by adding .375 to the DRO. This may not be the best way of setting the bit height, but I have been getting pretty good results.
My question: If and how would one put this .375 measurement into Mach3 to where when I am setting up my bit height all I have to do is zero the Z DRO and the program automatically adds the .375?
I hope I explained this correctly.
Thanks

Upper left corner of the offsets page. Enter .375 in the gauge block height, and click Set Z to set your Z zero position at .375.

Thanks Gerry.
That works, but is there a way to have Mach add the .375 when I hit the zero button?
In other words, when I am setting my bit height and I get it where I want it to be all I have to do is zero the Z and Mach3 will zero Z and add .375.
I may have to have some sort of macro to do this.
I am trying to get things setup to where I don't have to fiddle with the keyboard and can just do things from my new pendant.

It is FAR easier to use probing to set the Z position. Unless you have a tool changer, using tool length offsets really doesn't buy you much....

If your pendant has configurable buttons that can trigger macros then yes it would be simple enough to have the macro set the Z DRO to the value you wish.

The pendant has 2 spots for macros.
I guess I'll start reading up on them.
Thanks

Here is the code that is in the button on the offsets page that does your function. It should be a good example to help get you started on macros.
Code "G92.2"
Call SetDRO(2, Abs(GetOEMDRO(1001)))
Hope that helps, (;-) TP

Or if you will always use the same height gauge then just replace the last part with that height
Example is with your 0.375 above
SetDRO(2,0.375)
One other thing that may be worth mentioning is its better to move the cutter lower than the gauge then jog up in increments until you can slide it under. Doing it that way avoids the chance of moving too much onto the gauge and damaging the cutter, especially if its carbide.

Hello All,
Thanks for the additional comments.
I have done some experimenting with Klaus’ Screen Designer as the original Mach3 Screen Designer comes up slightly scrambled on my computer. Yes, I am using a copy of my screen set and have come up with a couple of solutions that work for my needs.
I was trying to get the functions that I typically use to run the CNC setup on my pendant to keep from playing contortionist in reaching my keyboard.
My pendant has two “GOTO” positions on it that were not working. One was Tool Change Position and the other was Safe Z Position.
First, I added another button to the Tool Information Block on screen 1 and labeled it “Tool Change Position” to replace the button that disappeared during revisions.
Second, I discovered that the Auto Tool Zero button in the same area currently is not being used as you get a “Yet to be implemented” message if you click on it. I relabeled it to read “Zero Z +.375” as I don’t feel I need a safe Z function.
Next I played around with the button defining blocks for these two keys. I used Hood’s (thank you) script for the Zero key and it works. I can click on it with the mouse or use my pendant to get that function to perform. I still need to tinker with the script for the tool change key to get it up and working.
Not too bad for an old fart Huh???
One question I do have is that when I was defining the keys in the screen designer I noticed that at the top of the defining block there was a Global yes/no selection. I figured this may mean that the function of the key could be allowed to occur no matter what screen you were on. Well, I clicked yes and things really went strange on me. The button wound up with a red line around it and the defining block changed to 3 lines with all my scripting and labeling vanishing. What gives with this happening??
Thanks everyone.

Sorry cant help with MachScreen as I dont use it, I use Screen4. I am sure someone will be along to help, if not give Klaus a shout as he is always very helpful.

I think you were suppose to push it BEFORE you defined any code in it.
Seems there was a manual for Machscreen somewhere.
(;-) TP

My button making and attaching scripts to them works. Everything functions the way I want it to.
The problem occurred when I hit the yes on the global selection at the top of the button defining box.
So, I just won't make things global and all works fine... At least until I find out what the global yes/no does....

Hello All,
I figured it out. ;D
After checking out the screens and going through the help (which seems a little vague to this newbie) I stumbled on what is going on. I am working on page one adding my buttons and scripts. When one makes a button global it gets a red ring around the button, changes your (I’ll call it for no better words “button configuration block”) to be a three line description and puts the button on page zero. If you then go to page zero and click on your new button, the configuration block shows everything once again, which will allow you to tweak things if needed.
The one thing of course that you have to remember is that when you make a button global it will show up on every page in the same location. I did not have a chance last night to see if the program prevents over writing other items on other pages.
Thanks again everyone for the help.
