Had a problem with the X2's circuit board so I was looking for a replacement.
I didn't want to spend $99 at Grizzly or $120 at Little Machine Shop.
I found a 130 VDC 8 AMP MOTOR CONTROLLER BOARD used in treadmills for $30 at Surplus Center.com. It works just as well as the original. You even have to cycle the power
switch (4.7k Potentiometer) back to zero when you hit the E-stop to get the motor to come
back on just like the original. The schematic for the circuit board calls for a 5k Pot to vary
the speed but the 4.7k on the mill works (just shuts off a little slower than before.) Use the
E-Stop to be SAFE! The only difference is there's no hookup for the amber LED.
Here's some pics

Cable Covers
With all the oil and chips flying around, It is necessary to protect the wiring. I covered
all the cables with Split Flex Tubing. I found some at Lowes in the electrical dept. It
costs about $3 for 6-10 feet depending on the diameter. I used 3/8 and 1/2 in.
Most automotive parts stores should carry it as well. I ordered most of mine from Wholesale Tool.
To protect the motors and digital scales, I'll make covers from thermoformable plastic
sheet. There are several brands to choose from but just about any plastic will be
formable when you apply some heat to it. I use a heat gun.
I ordered some Pet-G Vivak from US Plastics, they have good size selection and pricing.
This is a site for Kydex, Interstate Plastics, but they have a $50 min. order or you get
charged an extra $15 for a small order. Small Parts Inc. has lots of plastic as well as other stock i.e. aluminum,brass,steel, etc.
I'm going to order some Sintra PVC sheet from Foam Board Source.com too, They
have lots of choices and good prices and no min. order. Get up to a 4' x 8' sheet
if you want.

Toolmaker's Vise Clamps
If you have a precision Toolmaker's vise, These clamps are perfect to hold it to the table.
These are my version based on a set from Little Machine Shop.
