Not touched the mechanical design for a while as I got distracted down the route of designing my own stepper driver...
So here's a small update. I'm feeling quite bad for how much this is looking like one of JAZZ's machines! Believe it or not I am not trying to copy you Clive!
I am still not happy with the way I have the Y axis plates attached to the steel box section. Think I need to come up with something better?...

If you was, I would be more than excited,:pride: but I don't see the resemblance to mine if it is me you are referring too. ..CliveQuote:

All steel plate is currently 3mm ("Y axis "end stops" and end plate attaching bed), should I make this thicker? Will there be any problems welding it to 3mm thick box section? I have a friend who works at a laser cutting place so I'm hoping to get those pieces cut there.

Any comments on the above would be appreciated =) I think I need to start looking at places to get the aluminium milled soon!
I've been a bit distracted with designing my own stepper drivers but going to put that to the side until I have the mechanical design all done.
I think it would be better to extend the Z axis rear plate to meet up with the bottom plate, like this; it's not shown on this photo but my ball nut fits on the inside of that plate.

3mm plate is too thin I reckon, I used 10mm flat bar for brackets, maybe 6mm would do, see what others say about it.
Thanks for the input Eddy!
Well it's been a long time since my last post and since then there have been some large changes... Now, I am fully awaiting the groans and face palms when I say this....
I have decided to return to using aluminium profile for the frame. The reasons being:
1) My welding skills are not quite there. They aren't bad but I envisage a lot of trouble trying to get things square and aligned correctly.
2) I now have free access to a water jet which I plan to cut beefy steel brackets from to connect the profile together with.
3) I have re-evaluated what I will mainly be realistically cutting and steel may be OTT!
Anyway, enough excuses. Here's the latest design. I would really like to get the ball rolling with the custom aluminium parts. Am I best posting on the job request page and going from there?
