If you want it to run for every tool change, of every job you create in Estlcam, go to to setup-cnc programs-text-tool change. G0 Z5.0000 F480 ( Pull the Z axis back up off the workpiece at a feedrate of 480) G0 Z5.0000 F480 (This pulls the z axis back up off the workpiece at a feedrate of 480) G92 Z0 (This now sets the Z axis to zero at the offset above, meaning the top of your workpiece) This would be changed to the thickness of your touch plate. G1 Z-0.4 F150 (This sets the negative offset of the thickness of your touch plate.

M0 (Pause code until resume is clicked on the LCD.This is to un hook the touch plate and turn the spindle on) G1 Z2 F150 (Raise Z axis 2mm at a feedrate of 150 in order to remove your touch plate) This is for you to get your touch plate set up) M0 (Pause code until resume is clicked on the LCD. This reminds you to turn off the spindle) Here is the g code with comments that i now use with the LCD. Since i could now resume a job after a plain M0 code i re-wrote the g code to suit. After getting the LCD i have had zero problems. While using just the computer, i had issues with my usb connections going out on me and killing a job. Again i highly recommend the LCD and don’t see any reason everyone shouldn’t use one. (The code will now continue where it left off) G0 Z5.0000 F480 ( Pull the Z axis back up off the work piece at a feed rate of 480) Probably not necessary but i like to do it) G0 Z5.0000 F480 (This pulls the z axis back up off the work piece at a feed rate of 480) G92 Z0 (This now sets the Z axis to zero at the offset above, meaning the top of your work piece) This is to signal you to turn the spindle on) G1 Z2 F150 (Raise Z axis 2mm at a feed rate of 150 in order to remove your touch plate) In my opinion it is much better to leave it extra long or the code will start to home the z before you have your touch plate ready.) This time can be shortened or lengthened. This is disabled so you can manually move the Z axis up to get the new bit in) G0 X0.0000 Y0.0000 F2100 (Go to Zero on the X and Y Axis at a feed rate of 2100) This is to signal you to turn the spindle off) I have attached the plain g code for anyone to use. Here is the g code used without an LCD and comments to explain what each code does. I was able to write some simple g code that used this feature to do these tool changes successfully without an LCD. For example M0 S20 will pause the program for 20 seconds and return back to where it left off. Although after more research i did find that a timer can be set to the M0 code.
There is no code available to restart after a plain M0 code.
This can normally only be resumed by clicking the knob on an LCD. This presents a problem with tool changes because of the M0 code used to pause the program. I originally ran the machine without an LCD. Using the touch plate allowed me to explore typical tool change procedures. Home the z axis and viola consistent depth every time. You hook one wire to the mill bit and one wire to a plate, in my case a feeler gauge. After i started using it i really don’t understand why everyone doesn’t use it. I have attached a picture of the connections that have to be made for the touch plate. I did eventually find the info needed and got it working.

I had a pretty hard time getting a clarified reference on how to hook it up.
I had inconsistent depth so the look of the engraving varied quite a bit from piece to piece. I literally could not tell where the top of the surface was because the bit was so sharp and the material was so soft. This worked fine until i was engraving on ABS Sheet with a V bit. Like most people i just moved the Z axis until it touched the top of the surface. When i first started with the machine i did not use a Z touch plate. I thought i would hop on here and share my experiences with tool changes and the g code necessary to get the job done.
