Web Goblin cnc has begun

Hi all,
I havent managed to get much done at all in the last few weeks. I have a few jobs to do around the house and I have also been waiting on my ballscrews and nuts for around four weeks now.
Anyway the ballscrews arrived on Thursday and I got them unwrapped tonight. Now I`m totally hacked off to find that one of them is short by a long way. Its completely useless for my job. So I will have to speak to the supplier on Monday and get it sorted out.
Think I`ll go and take my frustration out on some baddies in Dead Space 2.

Right several weeks on now and guess what? My ballscrews turned up, well nearly. One of them is wrong again and I am going to have another two week wait, at least, to get a replacement.
I have managed to get some time in the workshop and have been able to get some more of my build done.
The Z axis is more or less complete and fitted to the machine as per the photos.



I have the ballscrew for the Y axis and have fitted the ballnut and mounting nut and the end bearings and it is just sitting on top of the frame at the moment for me to get some measurements. Next job on Monday is to mill a spacer block of aluminium 95mm x 75mm x 16mm thick to go between the ballnut mount and the Z axis frame.
The Z axis took quite a bit of work to get right. After it was made and assembled I ended up with about 1.5mm of movement in the screw from end to end so it had to be taken apart and a new spacer ring made to suit. Once this was done and re-assembled there is no movement at all that I can see so I`m happy with it now. :dance:

Regards

Ian
