Info Manual

Updated now working with full threaded rod that will move the axis. Connecting the rod to the stepper motor, i used those rubber guide of old inkjet printers as shown.
The stepper is a low torque from old fax machines i salvaged from my junks, almost all parts that make this a complete, A not perfect machine.










the dremel tool was changed due to the old one not rotating fast and sometimes halt when trying to cut through the material, the latter perfect fit for engraving.


















Video of the first run, and using KCAM 4 software instead of MACH3 for i cannot configure the latter to move the steppers correctly.
here, i am engraving my daughters name in a 2mm thick acrylic sheet, due the movement of the Y-axis and the tolerance of the shaft to its cradle, sometimes the position of the cut is out of position.











Needing to tweak the number of steps the motor must turn, finally i am up to engrave a full logo on a an acrylic sheet.

 some of those first tries engrave.


the finished HOMEMADE Hobby CNC router out from salvaged parts out of my junk back home.

CNC router is a computer numerical control that can engrave, mill, cut, etc etc. i am fond reading related articles about people building their own, so i came to my mind why not build one out from scratch. Before i started to construct one, i gather all the materials out from my junk such as printers, defective fax machines, and scanners, old cabinet for my frame, and slowly building the frame in comparison to othey DIY cnc.

Firstly, i decided to build my own stepper motor driver and test it using MACH 3 control software. After days of tweaking to turn those steppers out from old faxes and printers, finally i was amazed when they move for the first time, and said this is it. The steppers are of course those low torque type, since i am just trying to learn this for the first time, i'll go for this junks. They are model M42SP-5 unipolar stepper and an EM-199 from epson printer, all of them at 12 volts 180 ohms 7.5 degree motor specification.


After configuring MACH3 for the tachus42 unipolar stepper driver using LPT port. it is time to build my frame out from those animation featured on some site. I only got an old cabinet to dismantle saving crews, plastic joints, and the wood itself.
As shown with the frame box fitted with the X-axis steel rod guide, that are secured by those plastic joints i got from the old cabinet, it make sense securing it.









Since i only got acrylic sheets on a 3/4th inch thick, got an idea on how to make a guide for my
