Good morninig PCW;

Checked the voltages at the micro-stepper plugs this morning, all read either 0 v or 4.12 v, nothing in between. Although the high voltage is a bit low, I think it is within operational range. I'm not using an external 5 v supply for the board, though I have one to run my crosshair laser, so I could tap that supply if necessary. All of my dedicated power supplies 5, 12, 24 and 36 v are spot on their output voltages.

Not sure if it is the 7i76U or the 6i25 FPGA, which is configured as a 5i25, in the computer or something else that could be the issue. What is your suggestion at this point?

Hi,

Looking at your .xml file,
you have X, Z, Y, and SPDL, whereas in the .hal file you have X, Y, and Z, and the pins for SPDL are missing.

I believe that in the .hal file,
`loadrt cia402 count=3`

should be
`loadrt cia402 count=4`

Consequently, you need to add
`addf cia402.3.read-all servo-thread`
and
`addf cia402.3.write-all servo-thread`

Then, once LCNC opens, check that the pins in the .hal file match what you see under Machine > HAL Configuration
in the lcec and cia402 sections;
they must match it is easy to misspell pin names.

After the critiques and some changes I have almost completed my controller cabinet. It’s not nearly as Tidy as I would like but I think the airflow should be decent enough to keep it cool. Thank to all the comments and helping a first timer out.

Both linuxcnc and the preempt kernel come from a .iso file which is
linuxcnc_2.9.10-amd64.hybrid.iso
There a .zip file in forum.linuxcnc.org/38-general-linuxcnc-q...ing-program?start=10

which has polygonpocketf.ngc and makeholehere.ngc.

The parts are exceeding the limits set in the linuxcnc .ini file, when I correct this things work as they did on my other system. Sorry for the noise

Yea, I think that our reliance on random folk who come and go to provide builds people rely on is a bit short sighted, perhaps one of the worst aspects of this project. I'd say it's one of the downfalls of "open source", but plenty of other open source projects seem to have it figured out. Who knows, but it's why I just advocate for learning how to build them yourself.

At any rate, I'm glad to hear all is well again! Sorry for any inconvenience I caused. Happy cutting!

I had a similar problem (no errors displayed, only the motors did not want to turn).
I solved it by writing xml for one drive and when it started working, I connected the second one and added it to xml, and that way to the end.
I noticed that Ethercat in Linuxcnc is also sensitive to the order of entries, i.e. it may not work even if everything is fine, but incorrectly arranged...

Hi mwc,

Thank you for your help... The motors are energizing now, not moving but I am now where I wanted to be at 3 days ago. Thank you!

My ethercat_conf.xml was generated using the lece_configgen command. It looked correct... but nothing in the motor controller area was correct. I would have been better off using the instructions from the ethercat github page and just searching the forum here. 

Funny how both the Lichuan driver and the Stepperonline A6 drivers use the same code. They probably use the same (or from the same source) firmware. 

Connect ALM to joint.N.amp-fault-in

I recently tried to install CoolCNC, so I know what it real looks like.
Apart from the fact that EMC2 from 2005 bears little resemblance to LinuxCNC from 2026, it is practically impossible to install it on a modern computer, because the creators of kernel 2.4 were not clairvoyant and did not even foresee such inventions as SATA or a USB keyboard/mouse.

Really ?????

These are the pins of the optocoupler output transistors and they can be connected quite freely, as long as something limits the current to a safe value.
You can connect the "-" outputs to ground and the "+" outputs to the inputs that respond to a short circuit to ground, or connect the "+" outputs to the plus of the power supply (no more than 24V) and the "-" outputs to the inputs that respond to positive voltage.
Additionally, these outputs can be connected both in series and in parallel.
For example, the outputs of several ALM controllers in parallel (activation of any one will change the state) and PEND in series (activation of all of them will change the state).

  on 7i96 where should I wire the in position signal output and alarm signal output from the 2HSS86 Hybrid Servo Driver 

Yes, thank you! I should have come back here to report this as solved.

Even after waiting for a few days, upgrading LinuxCNC via the package manager still kept us on QtPlasmaC version ending in 84. Not sure what's up with the buildbot. So I set up a Debian VM here and built a deb from source to install on cutnweld's table. The QtPlasmaC version now ends with 88 and the pause issue is resolved. Thanks again for an awesome plasma control interface.
