2.8.4 Upgrade - Not Starting

I've been using LCNC 2.7 on an HP Compaq DC7600 successfully for a few years running my Emco lathe via Pico Universal Stepper Controller.

I wanted to upgrade to 2.8.4 to use G70+ and also change to a thin client HP T610.

I tested the T610 runs 2.7 fine on Wheezy before installing Buster and 2.8.4.

I did and ISO Buster install with 2.8.2 and updated to 2.8.4.

I then manually changed my INI and HAL files (script was uncessful) working through the 'DeBug' notes on the failed start up screen.

The last 'fix' was to compile 'emcochanger.comp' to 'emcochanger.so' BUT after this compile I cannot get LCNC to start or give any error message. When executing with the 'emco.ini' literally nothing happens.

LCNC will start with sim.axis or give error messages with the previous ini files but does nothing when executed with the attached 'emco.ini'.

Can anyone point me in the right direction please??

Thanks

have you tried to start your config from the terminal?

$ linuxcnc

should open the config picker window where you can choose your config. That should give you some output in the terminal window which my give an indication of what' wrong.

That helped a lot. Thanks Aciera!

It seemed to be [TRAJ] HOME= 0 0 in the ini that was the problem. I've just '#'d it.

HOWEVER, after correcting a few more errors I've now hit another brick wall.

LCNC 2.8.4 will now start, I can jog both X and Z via the keyboard arrow BUT Z does not show on the DRO although the axis is moving. X appears to be fine.

Both axis will home but Z will no longer move after X is homed.

I think I must have some JOINT_#, AXIS_#, PID.# references mixed up but have tried many combo's and can't seem to find the issue.

Any ideas??      (ini/hal attached)

maybe the addition of the HOME_SEQUENCE will help

at Joint_0 = 0
at Joint_1 = 1

Thanks mgm for the suggestion.

I've added HOME_SEQUENCE to the JOINTS and it successfully HOME's ALL but this did not fix the issue.

I don't think it's a homing issue as the DRO for Z is not registering when jogging before homing although it is fine for X.

Do you know which HAL line gives the displayed DRO value?   joint.#.motor-pos-fb maybe?

I'm fairly sure it is the manual referencing I've done in the HAL and INI for the 2.8.4 upgrade as it was all fine in 2.7

Not ot be omited, must be
HOME = 0 0 0
