PoKeys / Re: Mach4 and Pokeys57CNC limit switches

« on: February 01, 2018, 04:44:55 AM »

Well, this is more than a bit embarrassing, but I guess it happens. I must confess, I considered blaming it on a defective switch for a minute, but that's just not right. Got out my multimeter and did a quick continuity check and...no beeps, switch closed or open. I had run the two wires to the normally open and normally closed pins - of course it didn't work. A bit of solder and five minutes later, everything is working as it should!

Russ, thanks so much for your responses and waking me up to see the obvious! Very much appreciated! Case closed...

Thanks to all who read this as well - looking forward to more great info in the future!


Respectfully,
Marshall

Hi Russ,

Thanks for that. In all honesty, that is probably something I should double check - what exactly needs to be restarted after a config change like this? Pokey board, Mach4 software, both? Hopefully not the entire PC, that would be a bit much!


Thanks,
Marshall

You know, funny you should mention that. I did see the reference to the wizard and I thought about going that route, however it seems like I should be able to manually configure these switches without having to autodetect. At this point, I don't have that much set up either to have to blow it all away and have my settings put back to square one. I guess I COULD give that a try, if there were no other options. It does seem funny to have to go that direction though.

Thanks!

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
