Ok you will have to tune the IP-A, that will be why you get the ePID error most likely.

xml looks fine from a quick look although I am unable to see the tuning settings as you can only view if you have a controller connected.

But can i tune without any motion ??

Do i need to get jogging before tuning??

I have no motion at all yet from the keyboard.

Ok, i did an auto-tune in CSMIO and we now have some sort of motion :)

It does state that the drive has to be tuned first but have no info at all on that yet.

Also what about steps per - i just followed the CS manual.

Steps per will basically be whatever you want at this stage as you are just bench testing.
Think you had it set as 2000.
Your encoder is likely 10,000 per rev so if direct coupled to a 5mm pitch screw then 2000 would be correct.


You do realise once you have this hooked to the machine you will have to retune again :)

Yes of course, it needs tuning in the final condition. Just waiting on a reply from supplier about tuning the motor/drive loop.

How solid should the "lock up" be on a servo shaft?

It can be wobbled about but always goes back where it started.

You should not really be able to twist the shaft at all if it is just the shaft with no pulley.

Personally I would be setting up the software to see what is in that. You could use the computer that has Mach on it.

Yes, looked at the site and no info at all, sadly typical of Chinese stuff.
Hopefully the seller will get back with some info soon.

Might not be too bad - it seems the motor side is set when you enter the motor code into the drive.

Will leave it there while testing at least, plenty more to sort out ;)
