Hi Hood,

That's a shame with the grounding then Sad

Currently using the latest one which supposedly fixes this issue. Haven't tried older plugins. Could you please email me the one that works for you? What controller frequency do you have with it?

The lathe has been running for quite some time now. Sorry for not updating with a proper video, been short on time as always  Sad

I have been experiencing troubles with the ESS though. It keeps running out of data and no matter what I do it keeps doing this. Reduced the controller frequency to as low as 250Hz and it's at least usable, but absolutely frustrating with the delay on Feedhold, FRO and SRO. Anyway, seeking for a solution and for a correct way to do the wiring, decided to use a separate 5V supply for the ESS, to get proper isolation from the PC. What I had is a single PC PSU for all the logic - both 5V and 12V. However, unfortunately, I have discovered something weird with the  Ultra 3000 - it appears that its Common (ECOM) for Step/Dir input is grounded to the body and hence to the ground of my machine.

Is it really so (Hood?) ? How do I separate then the 5V logic from the rest?

I am looking at the state of the Ref LED for starting the loop so I have to de-ref first step so that it is in the correct state.
The Red for the homed LEDs are seen as active state, green inactive (if thats proper terminology Wink )

Not sure I understand. Still think it would work even without that If statement...

I have used the DoLoop for years, first used it on the big lathes turret, found it in a VB for dummies book I think, which incidentally is still too advanced for me to read and understand

Grin afraid we are in the same boat there.

Thanks for the snippet, Hood. I don't understand your first If statement. You first de-referenced the axes and then you're checking if it's really de-referenced? Why? Also, the conditional is not clear to me - your checking if LED 809 is active? Should it be '1' when red? Just tried to map it to a DRO and it's showing -1 for red and 0 for green.

The Do loop is interesting. Didn't know you could use such syntax to exit the loop. Will read the manual about the Do loop. Was always using While loops.

The RS485 is out of a box, Ian.

Ian,

You're right, it doesn't matter who does the homing first. I just feel more comfortable having the drive finish its task and then allow Mach to take control over. I agree though that the end result is the same.

Dan I home externally but I use VB calls not LEDs.
Hood

And you don't use buttons 22, 23,, 24?

Dan

Hood,

Are you not doing it the same way? Thought we had been on the same page.

Ah... yes, Mach thinks there are no home switches. But I can't use this as I am doing Button(22) or Button(24), for X and Z respectively, AFTER I get a confirmation signal from the drives. So the buttons above set the Machine DROs to zero and the standard Mach3 LEDs for homing are lit.

Hi Adam,

Just any DRO from 1000 to 2255. They are all user DROs.

Hi Ian,

We are talking to 2 slaves with the plugin Modbus at the moment with no issues, Using a RS232 to RS485 interface.

I am using User LEDs only to command the start of homing to the drives. You are not allowed to change standard LED's state at will so User LEDs were the way to go.
