Motor vibrations completely removed!
 Well, probably another error I found: the P value generated by pncconf
is set to 1, this is too high, I have set it to P = 100 and this
removed all motor vibration.

Re: [Emc-users] how to configure motors in pncconf?

[Peter Blodow]

Long time ago, pncconf had an error, so that it made 5 steps to a cycle 
instead of 4. This made the same symptoms at the steppers as you 
picture. What version of pncconf are you using?

the motor moves accordingly when I jog in Axis interface, and the
microstep scale is ok

I think if a bad connection was there, the motor could not move

Re: [Emc-users] how to configure motors in pncconf?

With a stepper that usually means the motor is stalled usually because of too

Hello,
What does it means when motor vibrates and makes sounds ?

The test window of pncconf is limited to 5000 and has disabled arrow
control, that means we can't set nothing higher than 5000. So, once
generated the config files with pncconf, I have edited the files by
hand, and now I am testing with Axis.

now I have set the parameters as follows:

step on-time 5000
step space 5000
dir setup 1
dir hold 1

When the motor is at rest (before any jog command within Axis), it does
not vibrate. But once a command is given, when it goes at rest again it
vibrates and makes sounds, until I disable from the Axis interface.

Thanks, and I have another question: how do we call the test window from
the command line ?

It is better but still some glitch, I can't set anything higher than
5000, the test window has disabled control arrow at 5000, in this
condition the motor vibrates or moves alone very slowly, I would like to
rise the dir-setup and dir-hold to 1 but the test window doesn't
allow this.

done with approximately same results

It is rarely necessary to make the step and space lengths as short as
possible, you tend to run into physical limits first.
Try 5000 for step-length and step-space.

You can also try inverting the step pulse polarity.

I lowered the speed to 750 and acceleration to 500 with much better
results, but still it moves alone very slowly. The step on-time value
seems to be ok but I need to fine tune this setup

Gotcha, I got the motor to move, but the movement is not precise and it
keeps moving slowly also if I don't press any button

the current parameters are, step on-time 3000, step space 3000, dir hold
5000, dir setup 5000

ok, that's a little step forward :-)

I think this is the problem.

https://github.com/LinuxCNC/hostmot2-firmware/blob/master/src/PIN_7I76x2_34.vhd

Shows stepgen.05 to be on the expansion connector, not the DB25.

Configure the X axis to be on Connector 3.

The X stepgen is show as 5 in the tab, and as
hm2_5i25.0.stepgen.05.counts in the test window, and it is changing
while I press the movement button

I don't understand why the first connector is show as 5 !?

I have done math for the scaling, not any magic, just motors have 200
steps/rev, in the drive microstepping setup at 800 microsteps, pitch is
5mm/rev, scale is 160 microsteps/mm.

It doesn't move at all

probably, another header is shown in the tab, because its number is 5,
but I have wired the motor to TB2 starting from pin 2 (step0-) to PUL-
on the drive. Why the first connector pin is not displayed as number
0 ? ...

Indeed, and also means that the drive is probably ready to move, but
not seeing step-pulses.

With the test window open, open a terminal and type

halcmd loadusr halmeter pin hm2_5i25.0.stepgen.00.counts

That should open a halmeter window, and you can check that LinuxCNC
thinks that step pulses are being sent (you can select to look at
different stepgens if necessary)

If the "counts" pin isn't moving then it is probably a scaling
problem, perhaps you need to move a whole inch (mm?) to create a
single step pulse.
If it is moving only slightly, then check that the motor isn't moving
imperceptibly.
If it moves a lot, and the motor isn't moving, then perhaps you have a
wiring error, or the pulse length is too short, or you are not wired
to the correct header.

There is an optional ENA, but it sounds like a disable actually. On the
drive there is a green led that is on (and the red led is off).

it is locked, that means current is flowing through the windings.

Do the drives also need an "enable" input?
Is the motor locked and not moving, or can you move it by hand?

[Emc-users] how to configure motors in pncconf?

[Valerio Bellizzomi]

Hello,
I am trying to configure motors in pncconf with 7i76 board,
I have selected the tab 'connector 2' and then selected a X-Axis StepGen
which shows a StepGen-A and DirGen-B, but testing the motor with the
panel it doesn'tg move. is this the right thing to do?

Thanks
