New build with recycled parts on a ridiculous budget 120cm*60cm work area

[Desertboy]

I made last minute design change it's now going to have a working area (Hopefully) of 1.2m*0.8m also trying to sort 2 slides for the other axis. The frame you see the long bits are 150cm and the short lengths are 100cm, width of extrusion is 4.5cm*9cm (It's the heavy duty profile).

Not for the first time I'm waiting on China post lol but at moment seems really good got arduino mega in 11 days, capacitive sensor took 14 days and my heated bed for the 3d printer was 16 days so seems a good time to order.

I am going to reinforce with steel angles before I put it together properly so the corners are more for alignment than anything else, I have considered having the frame welded I can get it done free ;)]

Just can't afford it at moment but eyeing up ballscrews in case I can sell a kidney ;) so we're still looking at belt drive at moment which works well as all my nema 23's have cogs permanently mounted on them.

I will buy a new nema 23 for the z axis (Unless I find one with a shaft) so I can mount it easily to the ballscrew.

I realise I can recover proper stepper drivers 4amp+ from the machines so will upgrade the drivers as and when but (If I can) will still use an Arduino to drive them.
