* <s>Y Axis pulsing - new connection spigot for drive year to fix eccentric rotation of gear</s>
* Remove and clean X axis gears, reinstall and use loctite on set screws (the keep backing off)

* Make sure all bearings are right against the rails so there is no slop
* Make sure all bearings are right against the rails so there is no slop
* Investigate backlash and configure mach3 is required
* <s>Investigate backlash and configure mach3 is required</s> - 0.0001 on X, Y and A
* Get quote for installing ground rod next to the table and execute it

* Look into THC issues (cut rippling) if still present after ground rod
* Look into THC issues (cut rippling) if still present after ground rod - possible Z axis flex in the mount to the Y carriage.
* Why is the THC seeing ~80V for a good clean cut from the hypertherm? Is the internal voltage divider broken (is this why the machine was retrofitted with a dangerous high voltage tap?)? Or is this related to a bad ground at the table?

** Do we need to add a CV on G-Code in the preamble of the post processor
** Why are there zero move G1's at the end of curves generated with G2's
** <s>Do we need to add a CV on G-Code in the preamble of the post processor</s> - Does not appear to need this
** Smooth stepper under-run errors - I have only seen this when jogging not cutting, mostly related to rapiding the Z, maybe reduce the micro stepping on the driver for the new threaded drive step count is huge per inch which could be hurting us

** Axis and Core frequency tuning for the smooth stepper?
** <s>Axis and Core frequency tuning for the smooth stepper?</s> - Dropped to 64k on X,Y,A
** Look ahead tuning
** <s>Look ahead tuning</s> - increased to 150
** Is CV plasma mode hurting us?
** Is CV plasma mode hurting us?
** System problems, AV jamming things up?
** <s>System problems, AV jamming things up?</s> - low cpu load not an issue
