ok …so i really like this MPCNC concept & i can see me making multiple of them. a CNC, a Plasma cutter & a larger 3d printer. not sure about a plasma build but hey ill give it a try. will probably melt the PLA. but maybe i could cast the 3d parts in alu?
i already own a cnc or a few lol
its the ebay 6040Z… a shenhui G350 laser. 7x14 mini lathe & well a couple 3D printers. so a CNC is nothing new to me & ive modded all mine a fair bit,
ive been planning on building a larger CNC for a while & i came across alteds design & been in love with it on the Price front for a few weeks!
your a top man alted & making it open source is just awesome! do you have a paypal for donations
now about the design!
I want to build a larger bed CNC using this design with some modifications of course. I want to do a 1.5m x 0.75m build & its actually just for 5mm acrylic sheet.
the few things im thinking of doing are basically adding a mid brace to the outer tubes along the 1.5m long sections.
so im basically thinking of this for modifications overall
1’’ solid steel bar for the conduits.
larger pulleys & belts like T10’s with idler’s etc instead of clamping or zip tying.
mid braces along the 1.5m long length (welded) to Metal base frame & bar?
Nema 23’s with a 6 axis bob… will only use 3 of them & maybe add a fourth later… i want to use mach 3 & my tradititional solidworks & well i just know my around these to well & dont want to change.

pulleys & belts http://www.beltingonline.com/timing-pulleys-bars-272/t10-pulleys-281/
I will also be remaking the Z mount for an acme ballscrew & will be using a 1.5kw spindle with a VFD.
this is just a basic idea & ive started to print the basic parts & will go from there. got the 4 corners done with clamps. 2 middle ends. 2 middle Z’s & printing the rest will be a few days.
any thoughts anyone on what else could improve it anymore?
