Chucking up that pulley to start making the taper boring, I found TLM
wouldn't run, throwing errors about a non-existant Y axis
I had not run it since before the joints merge.
3 hours worth of checking and editing later, I can make it run but the
axis's are all weird. Pressing a left-right key runs X, and the in-out
keys run Z.
Watching the leds on the bob, it is actually driving the wrong axis.
But, the DRO is showing the axis thats moving as the correct axis for
the one thats actually moving. Me confused. Bumfuzzled even. Configs
attached. Hopefully enough to run it.
What did I miss?

I have it working except the keyboard jog key assignment is wrong. I read
in the devel docs that there is in the [DISPLAY] section a
JOG_AXES = XZmore_axis_characters configuration option. Looking that up
in the online docs. it says this is the order of the jog key assignment,
starting with the left-right arrows being assigned to the first (X) and
Z is then assigned to the in-out arrows.
This jog_order is reported in the terminal window its launched from,
and if I change that string from XZ to ZX, it is reversed in the
But the actual keyboard assignment does not change, X stays on the
left-right keys, and z stays on the in-out keys.
Changing the trivkins coordinates=XZ to trivkins coordinates=ZX
apparently swaps the axis<->joint assignments, and I can't make that run
because the MAX|MIN limits don't match then.
So how do I restore the we're used to it for a decade or more keyboard
I've just now installed a new version.
linuxcnc (1:2.8.0~pre1.2926.g4564804) to 1:2.8.0~pre1.2939.g7f30fa2
so lets see if this problem persists.
But the actual keyboard assigns are left-X-right, and up-Z-down. I have
no clue if real gcode is similarly scrambled as well because it won't
home (or run an MDI command to see which axis moves) in this condition.
To me, this is a bug, but in that case the big lathe should be similarly
afflicted, but is not. But the linuxcnc versions there are not tracking
the x86 versions either. That machine has:
linuxcnc-uspace/stable,now 1:2.8.0~pre1.2771.gdc2ff49 armhf [installed]
Which I read as being behind quite a bit.
What can I do? I need this to make the taperlock parts for the bigger
Sheldon lathe's spindle drive. Which is all apart ATM.
