Crumbs, dont time fly by, hard to believe that it is not far off a month since my last update.
I have been working on this, but it has been a bit stop-start (more stop than start) as I have been just grabbing a bit of time where I can to work on it, so this post covers a few weeks of stop-starts.
I mounted the x-axis on the mill and it worked great, all it needed was a couple of 1-2mm thick packing pieces to go either side of the ballnut flange to fit neatly into the pocket from the old acme nut, then jsut tighten up the 2 grub screws and it was fine. Testing went exceedingly well and I am very happy with it.
That being done I replaced the X-axis back to the original manual acme nut and screw, and set about making the Y-axis stepper mounting, which is basically identical to the X-axis, so see the earlier pics for the details. Then I mounted the Y-axis stepper and mount onto the mill.
As you can see, there was a slight design flaw in that the gib screws of the x-axis would crash into the stepper mount, therefore limiting the x-axis by about 4-5mm. So as a quick and easy solution I just cut a little ledge into the mount with the bandsaw.
And here's a shot of both axis's
So now I can use the X and Y axis as computer controlled to help make the Z-Axis mount. It certainly is easier to just type in a command to move one direction by 72.3mm than counting turns of the handwheel. And being able to spot-drill all the holes at once and then go back to drill all the holes without worrying that you are drilling in the wrong place is just great. I guess it is like having a DRO, but instead of reading off the coordinates of where you want to be, you just type in where you want it to be.
So, onwards and ummm ....... sideways?!?!?
