Starting from scratch (again) - need help (apparently a lot)

I would use a minimum of 5000 ns step lengths unless it interferes with the maximum
attainable velocity. Using drive values ( which are typically _minimums_ ) is asking for
trouble...

Interesting
I'd already set them to 2000 (and found out that when you run pncconf again and it's still set to 203v it resets it back to 1000 so I've changed it to custom)

Any suggestions to the step space, dir hold settings?

Changed them both up to 5000 now

I usually suggest

Steplen 5000
Stepspace 5000
DirSetup 20000
DirHold 20000

As a starting point since these will work with almost any drive,
and there is no disadvantage to long times until they limit your
maximum velocity.

20000 (wow)
OK, i'll reset them as see if they cause any issues once this is connected to the actual machine bed.

Wiring in the limit switches now, Spindle is next

Random Update
Today I managed to get all the new parts, wires, etc all into one location and after a few backsteps and a spindle VFD wiring confusion (Sorted out thanks to PCW) I now have....
Movement in X and Z axis, both directions
Z limit and home working and back installed
X limit and home working (but not installed, really need to change the way I had the switch mounted so maybe now is the time)
remote E-stop switch working
Spindle speed and direction kind of working (RPM is way off, haven't done anything with the gear ranges yet but it spins up and down and reverses :)
Still waiting on new gears for the spindle encoder and I'll mount something temp in the mean time.


Need to tidy up the wiring a bunch as they are just loosely run over from the bulkhead fittings but I wanted to fire everything up before going nuts with the zip ties :)

Anyway, with all the various help from all the various people.... movement!!!

Next up, getting the spindle gears/rpm dialed in and maybe the encoder at the same time (would make it easier than using the laser tach on the pulleys...)
