Hi JAZZCNC.
Got micro switches today. I set 3 up for home but when triggered it says "limit switch triggered". When it did this I had to wind the motor off the switch by hand because I could not find a reset to move the axis off the switch. I'm still struggling with the setup due to lack of knowledge and I thank you for your time and patience. I have attached some info but don't know if it's useful.

Hi

Ok well that's a start at least some things happening.!

Did you change the limit inputs to a different pin number.? If yes then this is the pin number your switches are connected to so just set the Home inputs to same pin number.
If not then this also explains why limits are tripping because they where sharing the same input pin number so when you press the switch Mach3 sees the input and treats it has a Limit trip not a home switch.? Mach only sees the switch has home switch when you press "Ref all home"
You will tell if sharing same input has the LED's for both will light in diagnostics.

If you don't want the limits using these switches then either change the limit pin number or disable them.

With regards to moving off the limit switches when triggered then use the limit override button on the settings screen.

Hi JAZZCNC
Thanks for all your help,you have been invaluable to me sharing your knowledge and skills.
I am now able to get my machine to home and back off when it hits the switches. This is something I could never of done on my own. Now here i go again, How do i set the z axis block height?.
Your help would be great.

Ok sure I can help but need you to clarify what you mean by "z axis block height" .?

Do you mean to use the Auto tool zero and touch plate.? . . . Or do you mean the Gauge block height in the offsets Tab.?

Regards the Gauge block height then that's easy, enter the height of the Gauge block you place between the work and tool in the Txt box. (remember to press enter)
Then when you touch tool on block press the "Set Z" and it will set the Z axis DRO to match the block height meaning Zero will be on the material surface.

If you want to use the auto tool Zero then that's a bit more involved and will need some code inserting in the "auto tool zero" button script but easy enough to do just I will need to carefully explain so first clarify what you mean before get into this.!!

Ok but if you have a spare Input then making a touch plate and using "auto tool zero" is very quick and accurate.
Ounce you have used it you won't want to go back to manual way of doing things.!!

Let me know if you want to do it and I'll explain what's involved and post some code for you to place in the button script. It's not has difficult or complicated has it sounds so won't blow your mind. . Lol
