I did a test like the one Jon suggests yesterday with 150 repeats between Z
10 and Z 20, and the offset ends up around 2.2 mm even if I go really slow.
I just recently setup this machine and haven't really started to use it
until now, so it's a new machine and a new problem.
I'm using Rutex 990H
Sven,
I'm using Rutex 990H cards and Minerva (Yaskawa robot) servo's rated 67 V/10
A, and I have so much power in the electric feed I can use the control box
as a welding machine .
These Rutex drivers are step-servo drives, meaning that they convert a
stepper output (from your CNC
Sounds good, then I'm at least closer to a working config.
I did all the PID tuning, unfortunately I don't have the Step time-values
but I hope someone at Rutex can give me them. I'm close to giving up on
these controllers as I can't find info about them any longer except for the
PID tuning.
Hi Alex!
Thanks for the help. At the moment I can´t reach emc-developer-list, but
hopefully soon
I add the variables to EMC_MOTION_STAT and I could translate it without any
error. But it doesn´t work yet. In motion.c - update_status () I get the
right value, but in taskinf.cc -
Sven,
Just try some fairly safe timings. On my drivers I started with 20 us
step space / step time and 1000 us dir setup and hold. Those should be
real safe values.
I forgot, but is the problem only in the Z axis? With the axis always
going down ?
In that case could this be a mechanical slip?

Thanks for all suggestions! I'll try to set some safe values and I will also
check if there's a slip. The belt wheel is clamped with double nuts on the
screw and four lock screws from the side and inwards. It shouldn't slip but
I'll check it to be sure.
Actually, I think I noticed more offset when
I believe that Tom at MachMotion.com is the guy who sells Rutex in the
USA. I think they have a newer version of the 990H out now but I
haven't used it.
If you can't find the docs for the 990H boards I have them here
someplace. I still have two of those boards. I pulled them off the
Did new tests, and I reeeaaally have to go low on max speed to get things
going correct.
I bought these cards long time ago, but I did expect higher speed even with
an old PC. The computer is super fast with low jitter (about 6800 in latency
at most), the power to the drivers is

I'm still loosing on Z by the way, I'm starting to suspect a faulty driver.
Do you perchance have access to an oscilloscope?

Hello all,
Working away at researching my Anilam 1100 mill retrofit. Started to
read the EMC2 Integrators Manual V2.3. Seemed like the most useful
document for me at the moment. Figured I might learn something, so I
don't ask too many noob questions. So far so good.
Did get to an interesting
If you have a small stepper driven machine then homing may not be all
that important, but if you have a large high power machine you really
want to put the controls in the proper context before running programs
on it. In other words you really want to have it know where the soft
limits are.

The limit switches keep your
machine from crashing. So why home it?

Off hand, two reasons come to me.
One -- the hardware limit switches are a back-up to the software limits.
