I have a customer who processes foam and the foam dust is corrosive.
They process the foam with saws in several locations in the plant and
they have become masters at using air blowoff and air pressurization to
keep the dust out of the machinery. I'd consider putting a small
blower in the
Dear Steve
I use an X1 style machine for my show demo unit. One
thing that helped an amazing amount at higher speeds
was adding an outboard support to the lead screw. I
cannot take credit for the idea, because frankly, I did
not originally think it would help much. We have several
guys in

My guess is that the screw
vibrates in the clearance in the nut and anchoring the
outboard end significantly reduced the ability of the
screw to move off axis as it vibrated.
Oh, wow! This sounds like an equivalent of bearing whirl, where the
journal starts rolling
The machine is loaned out at the moment, and I don't
have any pictures. The leadscrew was extended by
drilling and boring a hole in the end, and then pressing
in the turned down end of the extension. The other
end of the extension was turned down to fit a single
standard bearing, not a preloaded
I do not know where you get the g68 code but coordinate rotation is
implemented in the development version of emc2. -This is done using g10.
Direction for getting it here

On another list, I have seen suggestion to use motorcycle chain grease if grease
is insisted on. Mainly because it does not collect the fine dust
particles like regular
grease does. It is designed for use in a very 'dirty' environment.

1/2 inch, and I've had it out, looks straight. Can't see any wobble when

From the drift in this thread it sounds like you have an X2 using
stock screws. In my case I abandoned the stock screws and went with
lower cost rolled ball screws. I decided the X2 wasn't rigid enough to
justify precision screws. Of course at 5 tpi I get plenty of

This spring a few folks put together a booth at the North American
Model Engineering Expo in Toledo, Ohio. We had a 10' x 10' booth
with two 8' tables, an Emco F1 CNC machine running EMC (mostly
cutting wax and/or air), and some great, large-format photos of
various machines that run EMC.
Dale,
PMDX would certainly be interested in coordinating booths
with any EMC related presence at NAMES. We had a choice
site at the last show, but due to the move, all bets are off.
The sooner we can ask for a group placement, the better.

I was dissatisfied with both the speed and the backlash so I
abandoned the stock screw and went to the ballscrew. I now arbitrarily
set the max speed at 80 per minute. During this change I upgraded to

So where does one get ball screws cheap enough to use on an X1 upgrade?
Depends how cheap is cheap enough. eBay is one source, I got my 8mm
Y-axis from there. I got the others from here:

I used Roton
http://www.roton.com/ballscrews-ballnuts-nav.aspx?line=Recirculating
for both my X2 and X3 unfortunately I only found the 5/8 screws
reasonable. Yes the ball nuts are a major cost as I use 2 for each
axis. Nuts less than $25 each. I don't know how they would fit in
