loadrt motmod not permitted

[Jeff Washburn]

There must be a permission file. The linuxcnc_module_helper documentation implies that there is a group list somewhere.

This happens whether it's a self generated halfile or one put together by Pncconf.

Perhaps it's because the 5i25 is not hooked up to the G540?

Hi Jeff,

What configuration do you use? A github repo you can link to? Pastebin? (No attachment please)

What does /var/log/linuxcnc.log say after starting your config after you've done "export DEBUG=5" in the terminal?

We cant guess what's going on.

Have a look at this configuration hal file

https://github.com/machinekit/machinekit/tree/master/configs/hm2-stepper

Especially the part about the "loadrt tp" and the next line where you also should load the tp=... and kins=...

loadrt gantrykins coordinates=XYYZ
loadrt [EMCMOT]EMCMOT servo_period_nsec=[EMCMOT]SERVO_PERIOD num_joints=[TRAJ]AXES
loadrt probe_parport
loadrt hostmot2
loadrt hm2_pci config=" num_encoders=1 num_pwmgens=0 num_3pwmgens=0 num_stepgens=5 sserial_port_0=00xxxxxx "
setp     hm2_5i25.0.watchdog.timeout_ns 10000000
loadrt abs names=abs.0,abs.1,abs.2,abs.3,abs.4

truncated at the end of the core input. This is from the Pncconf generated version. I have debug=5 in the INI.

Thanks, Bas. I had looked at the github fies you referenced, but glossed tp= and kins=.
