on another note what do you think of the idea of a counter balance on the Z... please dont shout your reply its only a question...:heehee:

[whisper]I think someone on this forum is considering it / has done it...
As I'm sure you know it should improve your Z-axis feedrate, but when do you actually need a high feed there? Possibly small drills (definitely with PCBs) and maybe with 4th axis in some situations but that's about it?
You can use an 'oversize' (i.e. greater than the mass of the head) counterweight to eliminate backlash in the Z-axis.

Are you using a rotating ballnut on Z, just out of interest?

I'm playing with the idea, primarily because I think it looks good, effectiveness be damned! :twisted:

On a related note, I also asked similar questions about the under-table mounting, the consensus seemed to be that it wasn't a problem. The following thread might have useful things for you: http://www.mycncuk.com/forums/showth...or-under-table

I will be using the Double ballnut if needed when i fit the ground Ballscrew but for now with the rolled i will use just the 1 with the ability to encorperate a double in the design..

LOL well here is the Vcarve output for the endplate for the Z with a side mounted stepper, or if prefered it can be hung on the end infact ive desinged it so you could hang it on the left rignt or even underneath,Ive not included the tensioning system yet as im still working on it. I still think it looks bodged on the end but that is just my opinion lol




I will make the prototypes out of a non metalic material i suspect...

Oh and ive made it incorperate the ballscrew Double A/C bearing housing as well.
