Possibly, look at some of the values and compare to the manual, if they seem sensible or similar then it might be ok. The supplier should provide a link though.

Yep,
I have an ongoing chat with a guy there, i have forwarded this last bit info to him.

Usually takes a week or two for a reply 

At least it proves it can work.

Different error every time, can't see any pattern to it at all.

It's bugging me that it works 100% in the config window, but 0% in Mach3 - makes me think it could be a Mach3 or Interface problem, it wouldn't be the first one

Yes i read the bit about the M20 and align at stop, i have turned off AOS but M20 still fails.

The get it to work in config all we did was tune the servo better. I have no idea what to look for but lion_rapid did, we went through it on the phone and it runs much better now, apart from this M20 thing.

Hmm,

I have been conversing a lot with member lion_rapid, great guy as you all are

We have managed to get the spindle tuned now, also I can get orientation to work perfectly in the CSMIO plugin config page. I have it set so I can insert a locking pin into my spindle shaft to allow me to unlock collets etc.

BUT

In M3/M5 and M20 calls orientation fails every time, M20 throws up angle errors every time. Having "stop at position" turned on in config  just makes the spindle stop at random locations every M5 call.

Baffled now - so near but so far away

Hi

removed the CSMIO connector, shorted the analogue input out and enabled it manually.

The motor was creeping, I tweaked the DAC offset a few mV and got it stationery.

When nudged by hand it was fairly rigid and held its position, no oscillating.

Re-connect CSMIO and it shows a DAC offset of 0.16V spindle is stationery, but still won't stop where its told or take any tuning.

Well, from what i can see it's just crap

My guess is that spindle orientation fails because it never reaches dead-band It will reach a stop but that stop can be anywhere from -200 to +200 or so in PID tuning.

No amount of messing with values has much effect, in fact its worse since i change the bearings from grease to oil lube, its very low friction and at my previous setting with P=7000 its now started oscillating instead of stopping.

Increasing P above 9000 seems to cause increasingly violent oscillation until it faults out or i hit the red button.

Maybe these servos are just garbage for a spindle?

I have the same drives and motors on my other axes and they all work faultlessly, big difference is friction damping/load.

With the spindle oscillating a gentle touch with the hand will stop it but dead-band is still off.

Its just the generic china servo from AASD - very popular due to price.

I have tried before setting the spindle as an axis the auto-tuning but it fails to get any sensible numbers.

I'll have to boot her up to get some figures.

I found any messing with values other than P was generally bad.

DAC offset was set and it is stationery when at 0 speed

I'll get some values when messing with Kvff, most likely in the morning.

M20 is as downloaded, no changes.

IIRC the errors were relatively high, I have spent hours messing with PID values, I can get the values very low BUT it will then creep to a stop or wobble erratically.

The ID values seem very sensitive which is why i left them out, it was the best option.

I did have a thread with details, i'll see if i can track it down.
