Peter said that they can get the data into the hardware but that there
is no driver support for it yet.
I need to get an SSI encoder.

Are those step-direction drives?
The general advice in the EMC2 world is to buy totally dumb drives and
do all the PID inside EMC2. Then you can tune in software, and use
Halscope to watch
There are a couple of other factors that can influence
how a G320X acts.
The following error limit is presumably set high enough
that the drive is not faulting.
The encoder resolution will affect the error gain. You
can set the "pulse multiplier" to influence this even
if your encoders do not hav
I am sorry to leave some guys struggling with unpacking the tar file for the
XYZACkins I posted on the Wiki. I wanted to pass it on in some other way,
but due to the fact that I lost the battle against a virus in my dual boot
PC, I have a delay to get access to the Ubuntu/EMC part of my PC.
I hope

I have tried all the settings from 256 to 2048 but it just makes it worse
Can you get the motor to run smoothly with no load?
Gecko drives have a sterling reputation. I doubt that the issue is a
Gecko drive and I think you proved that by swapping the drives already.
Have you tried driving this Gecko with a different output channel out of
the PC?
Are you happy with

I was anticipating that y
One more thing... if you swap the motor and you are just flat out of
ideas, I'd pickup the phone and call Geckodrive.
They will talk to you and try and help.

Well, it seems like it wouldn't be all that hard to adapt my PPMC
encoder car
How would that SSI to quadrature encoder work? The nice thing about
SSI is that when the power goes on, the motion system knows exactly
where it is without homing or moving.
I'm trying to find an encoder now.The best I have found far on the
surplus market is a 360 count per rev unit whi

That is on my list of things to try, but I haven't got round to doing yet.
