PoKeys / Mach4 and Pokeys57CNC limit switches
« on: January 31, 2018, 02:09:51 PM »
Hello all!

I know there are pages of comments about getting the limit switches to work with Mach4 and a Pokeys57CNC - I've read them all and I still don't quite get how to make these limit switches work! I think I must be doing something very wrong. I am also very familiar with this https://www.poscope.com/wp-content/uploads/downloads/Pokeys/LibrariesAndPlugins/Mach4%20and%20PoKeys57CNC%20-%20step%20by%20step%20guide.pdf document, especially page 14.

All I've done to test is to connect a normally open switch to the ground pin (pin 12) and the Axis 1 switch (Lim +) of the Limit/Home connector on the Pokeys57CNC.

Then, in Mach4, I configured the Pokeys Plugin - PoLabs, Pulse engine page - basically, I changed the Limit+ value to Ext. dedicated and checked the Inv.+ check mark. That's it, that's all I did. I apply the change and then try to job the Axis 1, expecting the limit switch to stop the motor from running, but it does not stop. I've also tried unchecking the Inv.+ box, but that stops the axis from running all the time, switch closed or not. I must be missing something simple.


Any help would be greatly appreciated!


Thanks,
Marshall
