Hi
I have been wondering the last few days on an 'open' data format for
controlling low cost, user built servo's.
The scenario of using a 'proper' closed loop servo for a small mill is very
appealing over a stepper.
While parallel ports are almost free and sufficient for steppers, to

Gentlemen,
I have a machine jump when changing from mdi mode to manual mode. X
jumps about .0025 and Y jumps -.0055 - Z A and B do not jump even when
A is not zero
My current kinematics is at www.mpm1.com:8080/cinci/cincikins.c
You will notice I have added Acomp and Bcomp functions. These
do I have to take the W axis into consideration also?

Gentlemen,
I think it is the difference between the joint[3] position and the

that.

There are several systems along these lines that already exist:
pico-systems ppmc, mesanet.com's 7i43, and pluto_servo all use the EPP
protocol for this purpose, and each one has established its own protocol
details.
There's also this project, though I'm not sure of the state of it:

I knew you'd give a comprehensive reply.
Notwithstanding, many hobbists build their own stepper drives. There's a
plethora of them. So now now it's open loop. Otherwise cobble your own
Step/Dir drive. Got closed loop, but two of them that meet in the middle. If
you want to build your
Hi Jeff
Yes, I was looking at most of them, but I suppose the data format is not
trivial, as it's adressing FPGA's. I would also think toe's would be stepped
on if one tried to piggy-back someone elses format.

Isn't the parallel-port going the way of the Do-Do pretty soon?
I remember
Yes, I was thinking of this too. The option is make your own PCI card. One
can get away with simple adressing, and doing away with the 'plug 'n play'
side of things. Imagine, a PCI card with dip switches!
Otherwise use a generic PCI chip like the Tiger 320 or PEX8311. The thing
is, why develop a

No, the actual error you encountered was almost certainly:

John, Sebastian and Peter,
Here is a combined reply, using John's post as the basis.
What kind of stepper drives? In particular, I'm asking about the inputs.
Optocouplers, or non-isolated? Do they have any filtering?
I am using an IM483 micro-stepping driver, the manual can be found here:
