CNC Router (Homebuilt & Incomplete)

I have a partially completed, homebuilt CNC router for sale. I started building it about three years ago but have not had the time to really do any substantial work on it for the last 2 years. I intended for it to be run using Mach3 using an old Celeron PC.

The frame is made from 50x50x4.5mm square and 50x100x4.5mm rectangular mild steel tubing with some angle iron supports for the bed, needless to say, a rather sturdy frame and very heavy (I intended for it not to move anywhere whilst running) and stands on 6 M12 x 80mm bolts to adjust it’s level.
The bed is currently unattached and is a 1800x1200x20mm sheet of recycled High Density Polythene (HDPE).

Motion system.

X Axis:   One drive on each side consisting of a MAE HN200 3426 0430 AX08 stepper motor driving a toothed belt reduction gearbox in turn driving a pinion gear on a rack. Two Rollon linear carriages per side which support the gantry in a single V track (TLC18) on the right and a single U track (ULC18) on the left.

Y Axis:   One drive consisting of a MAE HN200 3426 0430 AX08 stepper motor driving a toothed belt reduction gearbox in turn driving a pinion gear on a rack. Two V tracks, one above the other with two carriages per track.

Z Axis:   One drive consisting of a MAE HY200 2226 0190 AX08 stepper motor driving a toothed belt reduction gearbox in turn driving a ball screw to raise and lower the router assembly supported on two tracks with two carriages per track .

Note: The motion system is incomplete and needs a lot of work including component manufacture and engineering.



 

Router.

I made up a frame to hold a Makita 3612 (1650W 22000RPM) router, a very nice machine with a ½” chuck with ⅜” and ¼” collets. This frame will need to be mounted to the Z Axis assembly. The router is controlled by a simple triac speed control with a potentiometer mounted on the E-Stop control box.

Electronics.

All of the electronics I built myself, including the stepper drivers, isolated interface board, power supplies etc.



1. 40VDC 750VA Regulated Linear power supply.
2. Unregulated 12VDC 100VA power supply.
3. 40V 3A micro stepping stepper drivers.
4. Isolated PC Interface and control relays.
5. Triac motor speed control.
