Hello I have come as far in my retrofitting that it is time to begin with the control tuning.

I have begun to tune x and y axis but the x axis have some vibrations in it and this I could not really tune away.
So i began trouble shooting a little bit and pulled out the motor cable from the cable chain within the machine to just see if it could be a emc issue, witch seems to help, since i have changed out this cable. The cable shield is connected to the housing of the motor itself in the connector (M26).

The cable I used was an igus chainflex cf896.4.15.04 with approx. 60% shield coverage, is it safe to think that this was not enough?

The motor cable and encoder cables are routed in the same channel all the way from the cabinet.

What would be suitable shielding if i need to change the cable again?

Hi, Hakan!
Good points to check. Will do tomorrow
Also i first of all tryed to start from PreOP from started linuxcnc, but slaves command show me an error state..so i try to do switch To OP state manually.
So i build xml from xml odot file from their site, and also from ethercat sdos -p0 command.
Also thos evening im asked for deep seek about this problem, and also received some recommendations)) which also will check tomorrow and will write here about it.

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.
