Title: How are folks Homing the Slaved Axes when using a Smoothstepper ?
Post by: pkren54 on November 22, 2012, 12:26:42 PM

How are folks Homing the Slaved Axes when using a Smoothstepper ?  Particularly the Ethernet version of the SS.

I've read the Slaved Axis Homing feature of the SmoothStepper has some issues so I'm wondering what the alternatives are for homing that axis.    

Is anyone with a slaved axis using the SS's?  

I read on another forum someone was powering off their motor driver power supplies, grabbing the gantry and pulling it into the hard stops while turning the power supply back on and hitting the reference Home button.   Is that normal ?


Thanks

Hello, I'm using ESS with C32 and slaved axis with two motors on the x axis with no problems at all.

Are you homing the slaved axis to two separate switches? I know of at least one person who says it doesn't work correctly. And this has been a recurring theme sine the the first SS was released.

Yes, thanks Peter.    I've read where some didn't get it to work, it would be good to hear from some folks that did manage to get it all working.

Hello Garry,

I'm using only one home switch for slave axis.

I find that the speed/% of the homing is critical, Duel switches work on my large gantry router, but there was a dance between setting the speeds and debounce setting. My screen set's settings page has LED's that show when the switches are made. I just kept testing till I found a sweet spot.

So your using an ESS, and you can home a slaved axis with 2 switches? Just want to make sure we're on the same page.

Ya-Nvr-No, good to hear you have it running.   I'm curious which type of homing switches you're using, mechanical, hall effect, optical switches, etc. ?   

I've been wondering if perhaps the Hall effect magnetic switches might work well since there's usually some built in hysteresis that might help prevent bouncing/debouncing issues when the switch initially trips.

Just a couple of small adjustable micro limit switches with the rollerball on the lever end. NC looking for an open signal on X and slaved C axis. Found I could not go real slow. Set to about 30% for homing. It is around 300# 6 foot gantry w/ATC  and a 24 inch Z travel slide. So have no idea what a small machine might need.

I'm just letting ya know it does work, at least for my application.
Good Luck

Mine is working fine also.

ESS, two motors and two switches on X axis.
Running the latest version of Mach3 and ESS.

How is your smoothstepper setup.. Cause I can't get mine to work. I'm using an ESS Smoothstepper, well right now I'm not using it. But I have it sitting around, and would like to be able to do so in the future.

Thread is a little old but mine is still working fine.
What problems are you having?

I'm having the problem when homing x axis with a slave on two home switches.

I had an issue with that when I first got an ESS. 
The setup screen for the ESS controls the debounce for the inputs not Mach3.

That is where I would start.

Ok. I'll have a look at it if I mount the ESS again... :)
