really looking forward when to it. Still will take some time cause it is just hobby.
But I was able to setup the temporary workbenches.



the mid room shelves are also setup an I brought most of the boxes over:





 

I don't know how linuxcnc can bypass the count of Axis since it uses the same step generator for two modes. I believe it can, that's more a question for professionals, from my point of view I'm not very far from ``pncconfig``-. in my case, i bypassed it with only one relay that changes the mode on the driver via the M command M64, M65. but since you don't have an analog output, unfortunately really don't know how to help.

I have converted 2 mills with vertical and horizontal configurations. One does the switch in hal and the other does the switch in a custom kinematic.
I'd like to help but I'm not familiar with configs before 2.8.

this postprocessor refers to tool center, not tool length, so it exports gcode in relation to how you turned the spindle manually, straight or at an angle,  
it calculates the z coordinate in relation to the angle at which the tool is.

Most industrial machine spindle motors are induction type.
can facing and riggid tapping

it is special desgin . Rate about 1500 rpm only, and max is 8000rpm or 10 to 12krpm

Thanks for the reply

never knew such thing existed. Actually I asked in several forums including industrial arena, but unfortunately did not get such reply

will the spindle servo have enough torque at low speed? I may have to go low speed for facing toolpath (milling)

I would think that leaving it step/dir would be the easiest path
and would require few wiring changes. It also would not require
changing the drive setup, tuning the drives or tuning LinuxCNC's
feedback loop.

The only real advantage to an analog setup is that you can disable
the drives without losing position.
 

i have a working setup with mesa 7i95t (step/dir) and Delta B3-L drives. I am using velocity mode and feedback from drive/encoders, so position is kept while disabling the drives. That means you dont have to re-home after powering off, which is useful on long axes.
You have to tune servo drives in position mode first. Then you can switch to velocity mode and tune lixnucnc PID to minimize following error. I was able to reach the peak of ~ 0.005 during accelerations.

hi why you dont use spindle servo ?



induction motor with closed loop control, can run position/ speed control

Laut anleitung hat 7i96 kein 0-10v (oder ist das nicht dokumentiert)
Auch hat sie nur 6 ausgänge wir brauchen mehr welche Ausgangs karte kann man dazu stecken?
Welche auch in pnc conf Unterstützung findet

Das sind alles fragen die geklärt sein müssen bevor ich noch mehr geld in die hand nehme.

7i76eu wäre die erste wahl doch nicht fertig und 7i76 ausverkauft

I manually did that to finish the job, but it doesn't address the behaviours like tool length offset which are associated with Z.

 

A 7I96S has built in analog circuitry

Not sure how a 7I76 can damage a 5I25/PC unless a
high voltage (say 12 or 24V) is connected to the 5V pins

Das weis ich das 7i76 das kann,
doch diese scheint defekt zu sein und die 5i25 zerstört und weiters das mainboard des Rechners deswegen ja 7i95t oder 7i96 + output karte(welche)

Nur wie pwm in 0-10v regeln
