Thank You Very Much

Yes.

It been a long time since I have used classicladder but I think you need to link the set coil to a contact like in this example:

 

So you would connect your '%Q0' Output to the 'toggle' contact. (Like  'reset' in the example above but without the 'Time-off' block.)

Chat gpt hehehe.
Go into halshow and list all spindle pins.

Read the motion(motmod) documentation, the spindle section linuxcnc.org/docs/html/man/man9/motion.9.html

Look at one of the examples in linuxcnc .
Pins created by mb2hal are just as good as any other pin.

But there must be a reason that linuxcnc won't find it.
It looks okay in your files.
Response is exactly like it is commented out.
I tested to comment out the loadrt line and got exactly thisI also tested to mis-spell cia402pv.Spindl in the loadrt line and got the same error.
Also mis-spelling on the addf line give the same error.
There is some mis-spelling between the loadrt and the addf lines
but I don't see what it is.

From the output messages this is the hal file linuxcnc uses
./hallib/EL8_machine.hal
That's the one you showed, right?

I don't know. Can you retype those two lines?

hi there,

Just for anyone who searches and finds this, as of this writing (October 30 2025), if you have already run sudo apt update and sudo apt upgrade, you can't just run apt purge, you have to run:


And that will remove the error.

In addition, at least on my machine, after you run pncconf, you have to comment out lines 21 and 22 in order for LinuxCNC to launch.

Hi Peter,

Thank you for this information. Forgive me, I'm new. Are you associated with Mesa Electronics?

Regards,
John

I'll have to check that out.

Edit: This will take some thought to have the spinbox updated from the hal pin and the hal pin updated from the spinbox without a fight as to who is in control of the value.

There is no actual advantage to using a 6I25 configuration for LinuxCNC so they have been dropped
The VHDL Source is available if you want to compile something for a non-LinuxCNC application.

loadrt [KINS]KINEMATICS
loadrt [EMCMOT]EMCMOT servo_period_nsec=[EMCMOT]SERVO_PERIOD num_joints=[KINS]JOINTS
loadusr -W lcec_conf ethercat-conf.xml
loadrt lcec
#loadusr -W hal_manualtoolchange
loadrt cia402 count=4
#loadrt mult2
#loadrt mult2 count=4 etc for multiple instances
loadrt cia402pv names=cia402pv.Spindle

Doesn't appear to be commented out in the Hal file ?

Hmm, did you by any chance comment out the loadrt cia402pv line?

Oh, you're right, I always assumed they were MII chips, like on all other FPGA boards.

Hmmm, that could make things a lot easier, since the difficult part is already in the chip.

Thank you very much!!!

Hi Hakan
Thanks for the help I have configured to the directory now, but have a new error message ?
