How is a machine that tall cutting aluminum?!?!?

[@RajanNarasimhan]

very cool!

[@jamiekawabata7101]

The reasons for making it so tall are 1. as a challenge to see if I could do it 2. room for an automatic tool changer (kzbin.info/www/bejne/hYXEoKFom9uYhpY) 3. room for a possible 4th or 5th axis The method for stiffening the Z axis is by constructing a "double-decker" MPCNC, essentially two MPCNC machines stacked one on top of the other with a Z axis that runs through both. This is shown briefly here kzbin.info/www/bejne/moqTZIBtm62SkLc and a more detailed discussion here www.v1engineering.com/forum/topic/double-decker-build/ Even though the double-decker build takes about twice the material, the cost is still less than $600. X and Y dimensions are about 3' by 4', which allows approximately 2' by 3' of working space.

Brilliant

[@istvanmaasz6771]

Amazing, especially for such a big height! What's your calculated work area? What spindle are you using? Rpm? Thx 🙂

[@lindsay5985]

Please show us your custom bracing for such a tall machine. Thanks

[@JWGasner]

Why so tall? Great seeing the MPCNC cutting aluminum.

[@benh8core212]

Awesome, but whats your current size X/Y/Z of your mpcnc ?

[@jamiekawabata7101]

This machine has approximately 36" by 24" by 10" working volume.

@@jamiekawabata7101 thanks, this means X: 36" (91,44cm) Y:24" (60,96cm) x Z:(25,4cm) ? Normaly US conduits ? without support in conduits /etc `?
