What you will receive:

 

  • Complete set, of fully dimensioned CAD drawings, comprising 14 part drawings and 4 assembly drawings, showing you how to convert the X, Y and Z-axes to accept NEMA23 stepper motors. Supplied in PDF format and optional 2D DXF format , detailing all of the following: X, Y & Z lead-screws with adjustable anti-backlash nut , X, Y & Z lead-screw supports/bearings, X, Y & Z NEMA 23 stepper motor mounts.
  • A list of recommended material/part suppliers,
  • Complete list of fixings required.
  • A fully detailed 17 page, step-by-step Installation Manual with pictures, text and drawings. Supplied in PDF format.
  • A list of other parts required to complete the conversion.
  • Parts detailed have been, test fitted, and thoroughly tested for many hours on a working conversion. Designed to be easily made and fitted, with minimum modifications to the machine, using a small mill, and a small lathe.
  • A series of jpegs will also be supplied, showing pictures or the finished machine, giving pictorial ideas for routing the motor wiring and swarf-guards etc.
  • Drawings and Manual can be clearly printed on any A4 printer, (or A3 if preferred)
  • 2D DXF files are available, to help with any intended CNC manufacture of the parts. These are supplied at an additional cost of £9.99, and could save you a lot of time. Just choose before you buy.

 

What’s not included:

  • Drawings do not include details of electrical wiring information. Normally supplied by the Controller/Motor supplier.
  • Detailed drawings of swarf guards etc.
  • Details of any home/limit switches.
  • You are buying the Drawings and Manual only. No parts or materials are supplied
  • Listing shows images of the finished machine, for reference purposes.

 

Materials you will need:

 

  • Lead-screws, mild-steel, 14x3 trapezoidal threads, (Matching or home made tap will be required), 9/16" ACME, 9/16" UNC, or M14x1 stainless steel studding could be used.
  • Black Delrin ®, which is an acetal polymer, engineering plastic, e asy to machine. Free machining Aluminium (6082-T6/HE30) could be used.
  • Low cost sealed ball races , and thrust races, to mount the leadscrews.
  • White Delrin ®, which is a highly effective bearing medium with a low coefficient of friction, extremely wear-resistant. Phosphor Bronze could be used

Design:

 

  • Designed for Home/DIY use. The typical uses that the milling machine itself was designed for. Not really aimed at production engineering applications.
  • NEMA 23 motors (not supplied) are assumed to have M5 clearance fixing holes.
  • Motor spacers have been sized to suit Lovejoy L050 couplings. Other flexible couplings may be OK, but check compatibility and dimensions before buying.
  • Nuts are adjustable for wear, and when correctly set should give about 0.05mm backlash (which can be compensated for in Mach3 ® software etc)

 

  • The conversion will disable the manual operation of the milling machine. However, if stepper motors with double shafts are employed then some degree of limited manual use will be possible. No modifications will prevent the parts removed from being refitted to re-create the original manual machine, if ever the need should arise.
  •  

The parts are designed to fit with the minimum modifications, by utilising existing fixing holes etc. However, 3 x M6 holes and 2 x M5 holes need to be drilled and tapped to fit the Z-Axis lead-screw, and a small modification to the saddle is required to fit the X-Axis lead-screw.
