  • I’ve been reading everything I can get my hands on regarding the electrical design for this machine but I’m still most stumbling around in the dark. Everyone else seems to find is trivially easy and I suppose in some ways…

  • Limit switches or sensors are not absolutely required on a machine, it will work just fine without, but they are a very good addition as they prevent potentially expensive and dangerous crashes. There are three levels of safety when it…

  • I always knew that the electrical side of this project would be difficult but I hadn’t realized quite how difficult it would be. With the mechanical aspects of the build at least you can look at either the part or…

  • Since the last article all the way back in September the build hasn’t move very far forward but I thought it was time for an update as a few interesting things happened in the last couple of days. My main…

  • Those of you following my build logs will have noticed that the Wyvern machine build seems to have ground to a halt (as of Sept 2013). There was nothing inherently wrong with the build (although I can now see several…

  • Yet again it’s been a while since the last update because I’ve been debating what the best way forward is (read being indecisive for debating). As I mentioned in the last entry the bolting together plan was working, mostly, but…

  • I’ve not managed to get much done over the last few days as work has been getting in the way, I suppose I need to do something to pay for all this CNC equipment though. I’ve got all of the…

  • If you have been following this build you’ll know that I’m new to engineering so this may or may not be the best way to go about the task of fitting a bracket but what I can say is that…

  • It’s been a while since the last update, I’d like to say that’s because I’ve been busy building the CNC but the truth is that I only got a few days to work on. I’ve made a good start on…

  • Well I’ve found my new favourite paint in CombiColor. It goes on smoothly with very little odour and the coverage is pretty good considering it’s yellow which doesn’t tend to cover very well. That lot you see in the picture…

  • Before I piled into drilling holes in the actual steel that will make the frame I thought it was best to do a dry run with some of the off-cuts that I have. I’m really glad I decided to do…

  • The big clean up continued over the last few days. I was beginning to think that perhaps this coating on the steel should be left in place and that was confirmed by someone on the CNC forum. It seems steel…

  • The last few days have been devoted to the steel for the base. Someone I met through the CNC forum offered to source and cut the steel for me which has saved me a big job and I collected the…

  • Before I got all carried away and did something all unnecessary, like spend money, I thought I should try hand routing some aluminium. The compound table is only £100 but that’s £100 I wouldn’t have to spend on something else…

  • For the last few days I’ve mostly just been doing research into how I’ll actually build the frame and the rest of the machine. I found a really cheap welder (stock clearance) which I almost bought but I’m glad I…
