I take it you are printing the scale as 1:1 and not fit to page!!

Yeah :D tried fit to page first.. scratched my head when the print was 22cm instead of 16!
Now I get something like 16.8 :(

Well there is something wrong as even with a bad printer it should only be about .5mm out.

Can you measure the print exactly and work out the scale and then adjust it.

can you post the dxf up here and I will try and print it for you or adjust it in Acad

Ok edit: I have printed out in SW direct from the part on screen but you have to go into "file/print" and then page setup my printer shows "scale to fit" and "scale "100%" choose 100% It works for me.

Will try with new settings, maybe I have a scale error in the printer setup! If I can't get it to work I will pm you with the dxf Clive :)
Thanks in advance!

Hello everyone - bit of progress on the z axis... need to revisit the circuit diagram, the mechanical stuff is getting close now

[JoeHarris]

Following on from the pictures in the previous post above, another short video of the dry run assembly of the z axis below: https://youtu.be/_0nJBaUaBBA

I still need to make the bracket which fits between the top bearing mount and the z motor mount, the bottom bearing plate and the front z axis plate where the spindle will be mounted.

I'm going to open up the holes on the plates which pull the z bearings forward to allow better alignment. Align them with one another using the dial indicator... the problem is then I cannot get to the bolts which fix the vertical plate to the bearing plate to get that adjusted - wish I had foreseen these problems when designing the thing! Nothing some shims can't fix?!

getting close now joe!! great build.... if this is your first machine the feeling you get when your creation first comes alive is very strange ...
