This may not be the correct place and there may be a thread that address my problem but I can not get the Auto Tool Zero Touch Plate to work.
This is my set up.
I am not using any screen in Mach. I have added an LED to my touch plate. I have 2.5 volts to power things.
I am using the code that is at the top of the thread. Before I run the macro from my Shuttle Pro, I touch the plate to the router or bit and the LED lights and I can see on the Diagnostic page that a complete circuit has been made.
When I run the macro, the router is driven through the plate and wants to continue. It does not stop.
What am I doing wrong or what do I need to change. it would seem to me that I should be able to hold the plate in the air and once the router has touched the plate, it would stop driving downwards and set the Z to zero and move upward to stop.
Help please. If you need additonal information, let me know.
Thanks
Sounds to me like either your "ports and pins" are set incorrect or the touch plate is not triggering a signal to Mach.
There is some potential for confusion with Mach's terminology. On the diagnostics page the LED is called "digitise". In "ports and pins" the input is called "probe"
If you are sure you have that setup correctly and Mach is seeing the probe input change state on tool touching the plate then try this,
enter G31 Z-5 F5 into the MDI and as the Z moves down activate the touch plate. The Z move should stop when this happens.
If not then I strongly suspect that one of the aforementioned setup issues is in need of attention.
