The VFD does have a 0-5V frequency signal output. Wondering if there's a way I could use that for the spindle-at-speed after a spindle stop. Perhaps by simply comparing it with a threshold

Thank you

It’s obvious now, but since I bought it in the EU, I couldn’t find it…

For the past while i have been using mastercam v9 for my linuxcnc powered lathe , I use 3 M codes to select speed ranges , this was easy to setup in the mastercam post but im having a hard time with the fusion post.

All the information i can find online seems to be a bit dated or the post format has changed , it looks like there used to be a fairly simple section for the spindle but now is more complicated than i can handle.

1-649 rpm - M101
650-1199 rpm - M102
1200-2200rpm - M103

Here is what the code should look like , note the M102 before the spindle turns on , If using constant surface speed it should output the M code for the max RPM

G0 T0002 M06 G43
G97 M102 S1200 M03
G0 G54 X1.8013 Z.11 M8

I have attached the newest linuxcnc turn post with a few small changes i have made for other things.including G43 at every tool change .

Thanks for any help you are able to offer.

 

Hi,
I was hoping someone might have a firmware file for a 7i76eu & 7i85S that enables the stepgen index homing.  Or if anyone has any links on how to make custom firmware I downloaded the source file and found a post with the necessary changes, but I'm not sure how to compile the firmware.

I didn't have enough encoder inputs so I only connected the index signals from my servo drives to the 7i85S encoder inputs.  Thanks in advance for the help.  

X-Axis ---> stepgen.00 --> hm2_7i76e.0.encoder.00.input-a
Y-Axis ---> stepgen.01 --> hm2_7i76e.0.encoder.00.input-b
Y2-Axis ---> stepgen.02 --> hm2_7i76e.0.encoder.00.input-index
Z-Axis ---> stepgen.03 --> hm2_7i76e.0.encoder.01.input-a
A-Axis ---> stepgen.04 --> hm2_7i76e.0.encoder.01.input-b
B-Axis ---> stepgen.05 --> hm2_7i76e.0.encoder.01.input-index
C-Axis ---> stepgen.06 --> hm2_7i76e.0.encoder.02.input-a

No i have not, V6 Volcano only, modified the toolhead for it and longer StealthBurner.

Hallo karle,

über die offiziellen Qellen von Denain 12, auf der die ISO von LinuxCNC 2.9.4 basiert, bekommt man nur ein solch ältere Version.

Die aktuellste Version bekommt man ein einfachsten als flatpak über den Flathub, siehe flatpak.org/setup/Debian

Viele Grüße

If you got to Mesa's web store and then to the specification tab for the 7I96S
there is a support software download selection. 

This support software includes firmware files for the 7I96S

Hi,
I'm new to LinuxCNC. I tried to build a small milling machine and would like to control the VFD driver through Modbus.
I am using the Mesa 7i96s. I’ve seen some people mention flashing the card with "7i96sd_pktv2.bin" to remap the SSerial port to the PKUART port, but I can’t find this firmware.So, I’m stuck at the beginning…
Maybe I’m misunderstanding something?
Can you help me?Thanks!
