Hi Andy
Yep,Aluminum plates,not steel,typing error.
Yes,that would be option 2,I would have to make a 15mm spacer to mount everything together.
Option one is preffered,since milling two faces would not cost a fortune,if I go with handcutting alu plates,and It would reduce overhang by 15mm.I’ve put 240mm long gantry sideplates versus 280mm you did.I’ll have to finish z axis (spindle and mount)and run center of mass analysis,so then I’ll see where I am,if is needed to elongate sideplates or not.
Well steel frame didn’t seem that big of a hassle.I’ll check both options!Thanks for that.
If alu is chosen,kiln dryed sand is an option if resonance and vibratins occur as Lee sugested.
Yes its a bit offcentre so when ballnut and mounting bracket are connected nothing is sticking out of that T bracket,but yes I can beef it up a bit.
Andy you used 2010 ballscrew,so do I in this stages,but did you consider 1610 and making it both sides fixed?Did anybody do that?Rotational mass would be significantly lower with 1610.��
Never went in calculating critical speed for 1610 in fixed fixed arrangement,but I will,just to see what would be results in comparison to 2010 ballscrew in fixed/supported arrangement.
