Build log at last

[Gregor]

Thanks for all the advice
I have made a start on the design off the z axis which i am not sure if i have worked out the travel right so any advice would be great,I change the profile for the Y axis L shape to 90x45 I think it was in a post by Jazcnc that I was reading that it is handy for fitting the Hiwin rails to. Here are some pics with the measurements
Cheers Greg

Why have you gone for the square shape on the gantry sides as your previous post you shows it different. It might be better to show the z axis in more detail as you will need a cutout on the back plate and the front plate to accommodate the ball nut.

Sorry I posted the wrong pics here are the ones I should have posted.If my calculations are correct the spindle should be 25mm from the edge off the front off the gantry

If you have not bought your screws yet the Y screw could be made shorter and the pulley and the motor could be inside the gantry as you won't be using the full length of the screw.
Are to still at the drawing stage or have you started with the build?

Hi Clive
I have the base made which i welded for a friend but then he moved house and didnt have room for it so got it back but thats about it.I think i understand what you are saying something like this



Cheers

Yes because the ball nut is in the centre of the z plate you could also put the screw on the back but its up to you.

edit When you order the screws make sure you make the F length about 30mm you can always cut it off but not put it back on

Gregor not sure you have done enough checking etc to make sure things will fit correctly.
I know for fact how you have it designed now the ballscrew won't fit on the gantry without lot of messing about. You'll also get clashes from Ballnut brackets etc which will result in loss of travel.

While my design works great there's very little spare room so if your going to copy how I build them you need to follow exactly of at least check for clashes etc. This means more detailed Cad model with accurate models of parts used.

How you have it now won't work very well. These might help explain better.

Ok Greg the master has turned up. Take notice, I don't think he will mind copying it is easier that doing it for one's self

So look very carefully at the pics you will learn a lot.
