CNC Mill/Lathe

I purchased a ScanTek 2000 ScanMill (a rebranded Denford Micromill 2000) that consists of a Sherline 5400 CNC milling machine inside of a steel case.  It is normally controlled via proprietary software (VM Milling 5) that controls a baldor NextMove ST motion control board. I removed the top card of the motion control board and wired up connections to it from a parallel port break-out board so that I could control the mill using LinuxCNC (or Mach 3). You can read about my process here:

Oh yes, I also have a matching CNC Lathe…

 

A previous project I did involved constructing an X/Y table using Ikea surplus drawer rails, and you can read all about it here:

Costs:

Category Item Cost
Mechanical (IKEA AS-IS room) Base, X-platform, Y-Platform
X/Y linear rails (drawer pulls)
Raw Material (MDF board) for Z-cart & base
$3
$2
$1
Mechanical (ACE Hardware) M4 screws, washers & nuts (servo mounting)
wood screws
SM screws & washers
2×1 x 8foot piece of wood
1-foot plastic tubing
4 foot 3/4 inch steel angle iron
Eight 1/4inch bolts, nuts, and nylon locking nuts for Z-axis bearings
2x 12 inch by 1/2inch black “nipple” pipe (z-axis)
100pc box of 6-32 machine screws and nuts (pipe adjusters)
$2.21

I expect to re-use the steppers and driver electronics in my 2nd gen milling machine. I also bought a “dremel drill press” to use as a temporary (human operated) Z axis on my first gen router for $15.

  11. Jay I I’m doing your denford conversion using the bob you mentioned,I was wondering if you had a pinout for the 25 pin cable you used,there are tons of different versions out there,the one I have is a strait through cable with all pins going to the same number,some of these cables cross and I’m not sure of the one I need.
    Thank you

    • I believe I used a standard printer cable. I know that the one I bought from CNC4PC with the BOB was:
      A83 – 5 FT PARALLEL CABLE – DB25 MALE/FEMALE
      SKU: A83

      I think that one worked fine to connect the BOB to my computer. However, I *THINK* the cable I used inside the mill was this one:
      C2G 02665 DB25 M/M Serial RS232 Cable, Beige (6 Feet, 1.82 Meters)

      I believe the important part was that it had a male plug on both ends. This allowed me to plug a regular parallel port cable into the outside of the mill and then into my computer.

      The photos here show that the cable I installed into the exterior wall of the mill has male pins.
