Help needed!!! Hi just wondering if anyone can help, I saw a remix for the MPCNC by Ashraf Rizk aka dude9001. I am wanting to print the newer MPCNC and use some of his 3d files to make a really cheap 3d printer, however his hole sizes are 23.5mm, pretty much impossible to get in the UK, so i need to resize the lower4.obj file https://www.thingiverse.com/thing:1337765/#files and the extruder mount https://www.thingiverse.com/thing:1500668 to 25MM.
Im hoping with these files redone and a simple ramp 1.4 MOD to have a under £200 large dual extruder printer, all parts from aliexpress, heres how to modify the ramp 1.4 to turn the cnc into a 3d printer.
If I want to print or mill or engrave something 2 feet ( or 610mm or whatever) long, how long do the metal tubes (rails, this term is carried over from other projects I have looked into) need to be to allow the working area to be that big?
This is to figure the size of an area I need to have this do what I need before I get started on the build. So, I have studded the Mechmate.org machine, and it is about 2 feet wider and longer than the cutting area. (To cut a 4x8 sheet of plywood, the machine takes about 6x10 footprint on the shop floor).
