Are you saying the GUI never launches?

import linuxcnc and hal into the Python script, then create HAL pins to receive the spindle commands from HAL.

Load the Python script at load-time with a "loadusr" command in the HAL.

this is what i get running it from commandline. task: main loop ........

Can you report this problem on the issue tracker?

github.com/LinuxCNC/linuxcnc/issues

if this:

net estop-loop =>iocontrol.0.user-enable-out
net estop-loop => iocontrol.0.emc-enable-in

does not work, it's most likely because you have
estop-loop connected to another pin in the hal file.

Starting LinuxCNC from the command line will show the actual error.

Off-topic but I am impressed with the multiprocess welder at my local Hackspace. It allows you to keep both MIG and TIG torches permanently connected and has separate gas input spigots for each process gas. 
You are not wrong about the "serious money" part, though.

axis not working over vnc in my setup,

net estop-loop =>iocontrol.0.user-enable-out
net estop-loop => iocontrol.0.emc-enable-in

this is resulting in tklinuxcnc not starting, maybe its working with older software versions.

Oh, and why tklinuxcnc? There's nothing wrong with it, but it's rather outmoded and hasn't had a lot of developer attention for a while.

I think these need to be the same signal name to work as described. Try:

(note that the signal name is nothing special, there is no significance in changing it to loop, other than clarity. The important thing is that it should be the same name on both lines) 
 

Is this with the LinuxCNC install image?

If your Glade UI element is of type "Hal button" then the HAL pin will be created automatically and no handler file is needed.

(This is stated with 93% confidence, I don't have easy access to a LinuxCNC machine at the moment to test this assertion)

If you have proved that you can control the drive from Python then I would suggest carrying on with that.
You can "import linuxcnc" and "import hal" into your Python script then create HAL pins to recieve the position commands from HAL.

linuxcnc.org/docs/stable/html/config/python-interface.html
linuxcnc.org/docs/stable/html/config/python-hal-interface.html

I can try it, but since ethercat at the command line (linuxcnc isn't even running) shows ~50% lost uploads, what's the point?

I don't think this is a linuxcnc problem, but rather some networking or drive problem.

I think that the problem is inconsistent HAL signal naming.

You haveThen later in the file:
You need to connect the hm2_,,, pins to the halui.... (and motion....) pins.
Use the same signal name (the first term after "net") to link:

hm2_select pin / axis.L.jog-enable / joint.N.jog-enable

hm2_mpg_counts / axis.L.jog-counts / joint.N.jog-counts

You will also need to work out logic to set the scale:

(probably a mux block) axis.L.jog-scale joint.N.jog-scale

For initial testing, try:

(change the setp to 0.01 if using inches)

If that works, then configure the jog scale (but to help with that we wiuld need to know whether the MPG binary-codes the speed selector or has a pin for each speed)

(This is using the pins from "motion" which are slightly preferable to the halui pins. However HALUI supports analog jog mode, so has its uses.)
