I just replaced my USB SS (because of noise issues) with an ESS. I configured the ESS just like the USB SS was. Every thing works fine ,except when I home the machine Z is fine, Y is fine ,but X does the following: X=master axis and XA=slave axis
1st try- both homed and pulled off fine then X came back and hit the home switch again (everything works fine after this it's just not squared)
2nd try-both homed and pulled off fine then XA came back and hit the home switch again (everything works fine after this it's just not squared
3rd try -both homed and pulled off fine then X came back and hit the home switch again (everything works fine after this it's just not squared
This pattern continues,I even cut everything off and when I tried it again it picked up the pattern where it left off. I never had homing issues before.
Thanks for any help on this . Tommy

Maybe post up what plugin version and Mach version. I don't have any slave axes, but my 4 axis BP clone homes just fine with the ESS. Someone will be able to offer assistance, but SS and Mach versions often help.

I had mach ver, R3.042.040 but after you asked I remembered that useing the latest version was recomended. Now I have Mach ver R3.043.062 and ESS ver.ESS-v10a. I still have the same problem. Thanks,Tommy

Maybe search the forum on Warp9 for plugin version 10da2 and 10da3. I don't know why they don't post the plugin revs on the site, but they don't.
You might also try Jeff Birts configuration doc here. http://www.soigeneris.com/Ethernet_SmoothStepper-details.aspx
I'm afraid I don't know what else to say as I have no experience with slaved axes.

Thanks Tom, I will try that. Tommy

Hey Tom, Got the newest one I could find, v10da2 .Here's what happens now. X side homes like normall, but XA side homes like normal, stops where it should be,then comes back hits the home switch again, then goes back to where it should be, end result is everything ends where it should be,but with an extra step on the XA side. Maybe I will find the 10da3,Jeff's site gave me the 10da2 so I don,t know where else to look( kinda strange Warp9 would not have them on there site with the fixes the new ver. did) . Thanks again for your help, Tommy

Try here, a link to 10da5, the latest I know about and the one I'm using. Try with Mach dev version 062 available here on machsupport.

Thanks Tom,I installed the 10da5 and the issue is still the same. Gregg responded to this issue on the warp9 forum and will be working on homing and slave axis. I got the latest ver.thru your link but still can't find it my self on warp9,I'd like to know what I'm doing wrong. Thanks again for your help.

You're not missing anything on the warp9td site, they aren't posted anywhere!! I got the link to 10da5 because I was testing for some other software and ran into a SS issue. Greg fixed it, told the guy I was testing for, who told me and sent me the link!! I have no idea why these aren't available on the download page, perhaps with a warning, but they're not publicly available that I'm aware of. Hopefully Greg will get a new dll posted soon with all these little fixes.
-
Please be sure to let everyone know when this issue is fixed. I'd like to buy one, but I'd prefer if everything was working.
Thanks,

If this is actually an issue, it's the first one I've heard of with the ESS. My minor issue while testing for someone else, was so esoteric as to almost not be counted, probing in LATHE!! If there is a slave axis homing issue, it's the first ESS issue I've seen that might actually effect some folks. The ESS has been very solid and I, personally, wouldn't be the least bit afraid to buy one now. And it sounds like Greg is on the slave homing thing.

Sadly the step/dir spindle issues that have been there since the early days of the USB SS are still present in the ESS so there are still issues. The ESS however solved a lot of the other small niggles I had, none really serious but just quirky kind of behaviour such as on initial start up sometimes I would have to jog an axis before any modbus commands would work, with the ESS thats all gone.
As said the only complaint for me now is spindle, it will occasionally drop pulses for a split second, most wouldnt notice it but with my lathes spindle being very heavy I get quite a clunk.
Another issue is the SRO is very clunky and the drop of pulses for a split second happens a lot more frequently when SRO is in effect One issue that has been been reintroduced in the ESS is if you feedhold then press Stop the spindle will stop abruptly without deceleration, this had happened in the past with the USB one but was fixed a long time ago.
Oh also in threading the FRO is still active, that should be disabled and I think it was in USB SS but it certainly is not the case in the ESS.
All in all I love it and it works extremely well for me except the spindle control and threading issues.

I also had homing and just weirdness problems after I installed the ESS. I have a carriage type router with the A axis slaved with the X axis. Had all the problems that TommyD explained and several more in some of the M codes I had written.
So far every problem I have had has been fixed by adding a STOP command in the script. While troubleshooting I noticed that if I hit the stop button at the right time the homing and my M codes all worked fine. I don't know if it is the ESS not knowing when the operation is complete or if it is in Mach3.
I have no idea if it will help with the spindle problems but it may be worth a try as this stop command has fixed several other unrelated issues for me.
Add a "DoButton(3)" line to your script just for fun and see.
I am running Version R3.043.022 for Mach and plugin v10fb1 for ESS.

Not sure if it would help but I will give it a go, however Greg has said to me that he thinks there is a bug in his plugin code for the step/dir spindle but as far as I know he has not looked at it to see.

I'm trying to integrate an ESS board with a PMDX-126 on a CRP-4848. Homing the X axis and slaved A axis is failing with either both axis stopping on the X-Home and the X axis continuing into the end of the axis and hitting the bumper, or both axis stopping on the X-Home, the X stepping off the X-Axis while the A-axis starts moving positively until the gantry is twisted.
My reading suggests there is possibly an issue with homing slaved axis with the ESS. Any suggestions, hints, hopes?

Hi Analias, I'm also using slave axis with ESS and C32 board and it works well in my case.
