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

A 7I96S has an analog output

I would always leave the stepgen in velocity mode
and use a mux component to switch the source of the
stepgen velocity command from the PID output (C mode)
to commanded spindle speed (spindle mode)

Then a change to velocity mode is trivial. To maintain
position reference when changing back to C mode, you likely
need to home the C axis to index. Does the spindle have an encoder?

If not, a single index input will do if you have 7I95T firmware
with Step/Dir index (7i95t_sdid.bin)

sorry I left out the "don't"

That line has to be in the ha; file, not in a terminal.

Sorry
/boot/broadcom/config.txt

The file is the same as the official RPi image but in a different location. This is due to the patched kernel used.

The file you have to edit is:
/boot/Broadcom/config.txt

Not /boot/firmware/config.txt
This file does not exist in Rodw’s image. You must have created the directory and file.

I downloaded Rodw’s most recent image to check. I was involved when Rod was initially making the images last year. I did a fair bit of testing.

nop, no idea
how can do that ?

My googling shows hints that WinCNC has some s-curve support. But I'm not educated enough to know how complete or useful it is. Thank you for the first hand comments about WinCNC. 

Your comment about jerk limiting in the servo highlights a hope I had wrt the Yaskawa drives I have. But, alas, Sigma II doesn't appear to have this feature. I'm also confused about how a machine can keep synchronicity while drives are doing acceleration modifications in isolation. 

If I've read correctly, you are running primarily wood cutting machines?
