Ethercat installation from repositories - how to step by step

Category: EtherCAT

Update ... 
(After installing LinuxCNC 2.9.3 (Debian 12) and EtherCAT module (Master driver 1.6.2), I am unable to get EtherCAT communication working.  These slave drives work fine with LinuxCNC 2.8.  Something is different in 2.9.3.  What changed?)

However, sometimes one or more slave drives come up in OP state.  When a drive goes to OP, I can see position feedback, I can enable the drive, I can see the DS402 statusword (in drive software).  But it seems to be completely random whether the drives go to OP or PreOP ERROR.  Something must be working for the drives to sometimes go to OP, but I can't figure out what is causing the errors.

With only restarting LinuxCNC multiple times, I get different slaves erroring or going into OP state:

if the step scale is 100000, you should get 1 turn of the shaft for a .1" move
if the drive is set for 10000 steps per turn.

If not, the drives  steps/turn or encoder resolution are probably not set properly

Use a 1.5V battery, not 9V as that will have the motors run at full speed, and since there is not control to stop them, they will break something before you are able to remove the battery.

Thank you!
You can also change the work touch off it should also be one for each axis

1. Enable the drives ( how this is done depends on the drives )

Nothing will move without first doing that.

Powered up the power supply.
Enabled the motors and put 9v to the speed input on the drive card. Nothing. Found a 1.5v battery and tried that as well. Forward or backwards nothing happened.
Both drive and no motor movement either way.

Hooked 9v straight to servo motor with everything powered off and it runs forward and backwards like it should.

Here is a pic of that section of the ini  in the drive PA_04A number of pulses required per revolution is set at 10 000

I see what you mean about the tool touch off and that makes sense. I'll see about adding that in the morning.

.002 motion from a 0.100 command is what you would expect
if you used 100000 as the step scale but the drive was set for
500000 steps/turn instead of 10000.
