Mesa 5i25 + 7i77D can't cofig
How i can correct zero position in analogout?
And how i can make 5 axes in gmoccapy? Cos i how only 4 axis.
Thx.

Once configured,the drives should be disabled until LinuxCNC is running and
the feedback loop from the encoders is working, so no drift is possible in a working
setup.
The 5 Axis question is probably better asked in the gmoccapy section of the forum

My X axes - work normal, in pncconfig response normal. In linuxcnc X - make some noise and little jump.
Y axes - normal response in pncconfig but in linuxcnc make big jumps and loud noise
Z axes - normal response in pncconfig. In linuxcnc after press enable Z axes make earthshake for 1 sec and drop to error joint 2.
In your instructions you say if joints make noise or jumps put in calibration joint 2 (Z axes) "output scale" -10. In jog speed i set 15mm/min. I press test button then pres enable and Z axes go to one side fast.
Your instruction i translated in google. What i do wrong?
Thx

Do not change anything or try to tune or calibrate without being able to enable the machine and no motors running or vibrating.
Z axis is not wired or set up properly so it can not be tuned before fixing that.

enable/disable the drives before continuing. A runaway can hurt you and or the
machine.

-- I already wired pin enable output to relay contactor (enable on = 200v go to power drvers/ brake resistor disconnect) (enable off = power off/ brake resistor connect)
!!!But i connected "permission to move" on drivers by jumper!!! for avoid electromagnetic noise to analog control pins.--
2 step: I mast connect control pins for axes what i tune and when enable on motor mast stay still ? But motor can make some sound and little jump while move?
3 step: Go to "calibration", lower the P value to get minimum noise at stop position and disable jumping while moving?
Its plan minimum for tomorrow
Please correct me if i wrong.
If need move topic to correct thread of forum.
Thanks for your help!

Drives disabled and move motor by hand, check DRO if it counts correctlyTaichi wrote: 1 step: I mast check all encoders for normal connect and test them separately from drivers. DRO mast counting while "enable" turn on and power to drivers disable if i move axes by hands?
No jumpers! LinuxCNC must be able to disable drives when required. This is very important.Taichi wrote: -- I already wired pin enable output to relay contactor (enable on = 200v go to power drvers/ brake resistor disconnect) (enable off = power off/ brake resistor connect)

Yes. But if the motors jump when enabled, wiring or hal setup is not correct regarding direction and that can be changed in hal.Taichi wrote: 2 step: I mast connect control pins for axes what i tune and when enable on motor mast stay still ? But motor can make some sound and little jump while move?

Then i lower P value for X = 40, Y = 40, Z = 10.
"Permission to move" connected to ENAn+ and ENAn- as you said.
Results:
All axes response and move correctly when i press +\- from LinuxCNC
X axes - stay still and have minimal noise. DRO jump to 0.001
Y axes - stay still, i can't hear any noise. DRO stay still no jump.
Z axes - stay still, but have loud noise and vibration. DRO jumps 0.01 - 0.002 at this division.
To change P value of Z axes - not response. I try between 5 and 50 P value.
Yesterday, you said then no reason to continue tuning until fix this vibration on axes. So i decide to wait your reply to continue.
Thx.
