Sounds like some of us "rich" US guys (in UK terms) may need to visit
your fine country to help prop up the economy. :-)
I could go for some cheap Bangers and Mash.
On the other hand, our election process may drive our economy into the
dumper come November also. :-/

Those do look like an easy solution, and they seem to have taken

But for that price I think I would be looking at making patterns,

You might also want to take a look at the headstock offerings from
GlockCNC. They're intended to be precision upgrades for the little
Sherline lathe, but they should be easy to use as the basis for a small
custom lathe of your own design. They have versions from ER-25 to

No problem!

Well the VFD does have a minimum speed. It won't run below that because of min
speed and overheating.
I did see a freq of 300 (18k rpm) on the HAL while the VFD locked up.
Also MDI'ed S18000 in while the VFD was locked up.
Looks like the watchdog_out to the VFD is a problem here.

Iirc Pressing axis spindle buttons sets the rpm to 1 rpm. Maybe this is the
problem. Some how that errors the vfd. Depending on what version of lunuxcnc
there is an INI switch to change that default rpm.You should be able to test
this by setting the rpm to 1 in the MDI window.
Worth a try.

through the HAL pins?

How is LinuxCNC connected to the VFD?
Direct hardware control, with an analog speed command and start/stop signals
from a parallel port?
Or serial communications using a HAL driver specific to that brand of VFD?

Or Ethernet using ??? driv

In that case the Z offset is irrelevant, but you probably still want

It's every single time. If I use M3, spindle runs 100% reliably. Or, if I use
my XHC wireless mpg, that runs it fine too.
But on the Manual Control tab, there's a Spindle button with a CW button
flanking it on the right and a CCW button on the left and +/- buttons
underneath. Hovering over t

It does not have a controllable Z, it is a two position up/down.

when the fibers are cut I get a small amount of expansion so the part to be

eBay is full of them. (well, not literally).

Have any of you come across cheap collet spindles that

Do you have the motion.spindle-at-speed pin connected up? Perhaps this
is what is preventing machine movement?
