Yarg. Why do simple things always create the longest hold ups?

29/11/2008 by peter.

To machine the various square orifices required for the USB port and the LCD display I need to use my rebuilt Boxford. One problem, the software was still buggy and I haven’t written anything to generate control codes to give it. Simple solution, write a manual controller. That took all of 2 days of spare time to add all the features I wanted and with this I set about making the rectangular hole for the LCD. After much standing and watching the machine produce fine swarf as it slowly ploughed through the metal I had a nice rectangular hole. I de-clamped the box to admire my work when I realised I hadn’t drilled the display mounting holes which would be a lot easier under numeric control. Unfortunately while edge finding the rectangular cut-out, I crashed the machine into the top corner of said orifice (hit “End” instead of “Page up”) then I got the holes slightly in the wrong place but that’s one reason why I will make 2 of them. The first to screw up one and second so that I can test new code and features on my own one before sending the updates of to a beta tester.
The other minor annoyance is the lack of M2.5 nuts to fit the M2.5 LCD retaining bolts. For reasons of stupidity, I ordered M2 nuts. Well it will have to wait until I have a few more bits to order. There’s no point in paying postage on only one tiny bag of nuts.

Anyhoo. Piccies of the box so far
