I recently wrote about some of the problems I’d had with the Chinese Laser Cutter I bought over eBay. It became apparent that I was going to have to replace the X/Y controller board, as this was not functioning correctly. The Challenge – adding a new controller I just pulled my old CNC out of […]

And things were going so well… When I first connected the software to the cutter I could get no response at all. I examined the supplied parallel cable and found that some of the pins had been pushed in. Nothing that couldn’t be fixed with some needle-nose pliers. So I fixed the cable and plugged […]

2012 UPDATE: Check out the new laser cutter I built from scratch here -> New 24×18″ CO2 Laser Since building the CNC router last year I’ve become increasingly interested in adding a laser cutting/engraving head. Scanning eBay I found lots of component parts, but I did not have the expertise to create a working system. […]

QRD1114 home sensors installed and tested

July 7, 2010

I “test fitted” the sensor circuits to the gantry tonight and I’m pleased to say that they work with a surprising degree of accuracy. The sensors are wired to input pins 11 (X), 12 (Y) and 15 (Z). I used the Mach 3 “auto set” feature to configure the pins as home for M1, M2 […]

First cut with the CNC

April 26, 2010

I finally managed to cut some material on the CNC router this weekend. (Although I needed to take a 4 day weekend to do it). The material was MDF, which is nasty nasty stuff, hence the “Dust Control Bubble” ™. I can cut at 100 inches per minute with a 0.1 step down on the […]

Box of Mystery II

April 16, 2010

A while ago I made a posting about my “Box of Mystery” and asked if anyone could guess what it was for. I got some interesting responses, but none of them correct. I’ve made some significant progress since, and so I thought I’d post a video…

Finally got the clock on the wall

January 17, 2010

It’s taken most of the weekend, but I finally got the clock up on the wall. The more observant reader will spot that the driver weight is missing – so it’s not ticking yet. Also despite my best efforts with a custom jig, the pendulum balance is a little bit off – so that will […]

…making a clock.

January 3, 2010

I was inspired by the recent documentary on Kit Williams to look into wooden clock making. Also, I thought it would be an excellent test of the CNC router I built over Christmas. So after a week of learning about ramping, lead in and out, cutting paths and other engineering type stuff I finally got […]
