VERY newbie question. I don’t currently have a 3d printer, Im going to buy these first printed parts.
I want to build this first MPCNC (3d Printer) with the capacity to print more iterations of this machine. I notice that the Z parts require 120mm space. Does this mean that for this first build I would need to increase the usable height of my MPCNC to 5ish(4.79) inches? Or can I rotate the print orientation and print Z parts horizontally.
Additionally, have any of you found difficulty with raising the height above the suggested 3″ for a first build?
Thanks in advance.December 10, 2018 at 2:28 pm #78931
If your plan is to make a 3D printer, it really is best to build a 3D printer. The MPCNC is a great CNC that can print really big things, but it is not as good as a small standalone printer for printing.
In other words build the machine you need for your primary purpose.December 10, 2018 at 3:18 pm #78935
Said the guy who built this beautiful monster 😉 https://www.youtube.com/watch?v=DeVeyUas5vU Hahaha.
Say I had to build the extruder into this first build, would I need to raise the height to 5″ish to print the XYZ parts for the MPCNC?December 10, 2018 at 3:51 pm #78939
Really, Ryan is right here. Build an MP3DP and use it to print the parts for each successive MPCNC. It’ll be a lot easier and you’ll be able to get a lot more help with the 3D printing learning curve using a reasonably standard printer.December 10, 2018 at 3:56 pm #78940
Tool mount is the tallest.
How many CNC’s do you plan on building?December 10, 2018 at 4:01 pm #78941
I’m shooting for 3. Dont 3d print much, but I do want the capacity to make additions to the machines I have, and print new ones/features if needed.December 12, 2018 at 9:14 am #79135
I’ve never used my MPCNC as a 3D printer, but I did originally build it with a 5″ usable height. It gave me some weeble wobbles right off the bat, so I cut it down.
That said, if you are determined to use the MPCNC as the replicating machine for more MPCNCs, I think you’d be clear to build it taller if you get creative with some sort of wooden sidewall setup. Basically build the CNC as normal, then add a structural box, or some kind of bracing, around the sides.
I wouldn’t reorient the parts on the print bed, personally. Ryan has optimized them pretty well to print as is. I say try out the tall build, and don’t look back! At the very least, you’re gonna learn something- and changing Z height is super easy.
