Hello,

I just wanted to write you this mail, as I have to thank you for your great help!

Finished installing the mechanics yesterday and spent the day soldering and wiring my controllers.

On the X2 mill I’m getting 150 IPM using 270oz-in steppers and I’m pretty confident I can get even more.

I spent a lot of care installing your kit, polished all guiding surfaces and straightened everything out. I have also installed a gas piston on the Z; it’s much needed IMHO. Currently driving the Z with 100IPM without lost steps and both X and Y with 150IPM. Tomorrow I’ll measure the backlash for the software compensation and try to find the maximum speed possible.

Thank you again,

Best regards,

P Ingels

I have just finished my 5th and final refit of my X2 Mini Mill.
After trying many different Drive Screws, 16 pitch, 20 pitch
(littlemachineshop) Acme 10 pitch, found on Ebay, Messing around
with Steppers from 100oz - 1020oz, lapping the ways... the list goes
on and on.
I ran across KDN TOOLS, and his retro fit for a X2. I first obtained
the Z-axis Ball Screw Assembly. Mounted it to my X2 and Tested. HOLY
#$@& the Z axis was able to move over 50 inches a minute. (The best
I did on others was 10 stable, 15 unstable) I measured the Backlash
and it was .0004. Hard to believe with the mickey mouse ways that
come with the X2. I then added bellows to protect the Ball Screw.
Cleaned it all up and locked it all down. (By the way, I am using an
820oz NEMA34 stepper on this.
I was so impressed with the Z-axis after running for a week, that I
ordered the Advanced X and Y ball screw assembly (for Nema34) I
installed them on Xmas Day. Tuned up every thing. And HOLY #($# My X
and Y axis move at over 50 inches a minute (stable), backlash
is .0004 on both axis. (By the way, I am working on some new way
parts that should take the backlash down to .0002(3).
(I use Sound Design Breakout boards, with their Spindle Controller)
I then began my super test. Loaded up my 6061-T6 Material and
started my process. Instead of 2.4hours to bill a 6-pole strip line
filter for Microwave, it took only 24min. What a savings. Moreover,
the finished product was 3 x better in finish, and accuracy.
In Microwaves, 1/1000 matter greatly.
Therefore, I can not speak any higher than this. Need a CNC mini
mill. Get Mach2, Sound Design Boards, and the KDNTOOLS Advanced
Refit Kit for X2.
