Wasn't me. :)

On my acme screws, I use pnumatic tool oil.

I'd just recommend any light oil or grease. Just be aware that if you don't have good dust collection, it'll be attracted to the lubricant.

Try reducing the acceleration to 75.

Looking at the specs, it seems to be somewhat underpowered. Make sure the screws and bearings are well lubricated, and make sure there's no binding anywhere. Disconnect the motors and make sure the screws turn easily with your fingers. The slightest amount of binding can cause problems.

Does your g-code have a G21 in it? I'm pretty sure it's a units issue. Probably opposite what I said before. Machine set up in inches, and running a file in mm's.

This sounds like your native units are mm and your loading a file with G20 in it.

I use an old Dell GX150, 1Ghz PIII. $25 for motherboard and processor on Ebay, and it runs great at 25Khz. Only problem is the screens are a bit sluggish.

Just like this one. http://www.ebay.com/itm/190447069240?ru=http%3A%2F%2Fwww.ebay.com%3A80%2Fsch%2Fi.html%3F_from%3DR40%26_trksid%3Dm570.l2736%26_nkw%3D190447069240%26_fvi%3D1&_rdc=1

Just be aware that the power supply pinouts are non standard, so you need the correct power supply.

A lot of people have good luck with Atom motherboards, which you can get for $50-$75 new.

When Set to "Stop Spindle, Wait for Cycle Start", Mach3 runs the M6Start first, then stops and waits for Cycle Start, then runs M6End.

If you know VBA, you can write a macro for Excel to export g-code directly from your spreadsheet.

Because there is no lockdown version where everything works.
