Is they are any way you can release source files?

 

I'm curious what control board you are using. Looks compact but I don't recognize it.

 

you can use ramps or anything that runs marlin.

 

yo indie is it possible to get the solidworks files for this?

 

Very nice. I like the design. Thank you!

 

Hey indie, pretty nice.

Do you mind sharing overall cost for the build. Thinking on doing something similar but would like to get myself calibrated cost wise. Thanks

 

what is the tool you used for simulation?

 

How are you able to make sure that the free end of the x-arm doesn't sag or bounce? I like the build style, but worry about print accuracy the further down the rail the head travels.
Looks awesome

Cheers,

I'm working on a similar "one arm" design with a 8x8 build area. I mounted a dial indicator to the back side of the x axis arm out to the right side of the build bed and set it so the dial depressed half a revolution all along the y axis. I then printed (without filament) a first layer of an object the full size of the bed with 90 and 45 degree angle settings. Bounce or sag should show up on the needle as vibration. I tried it at 30, 100 and 150mm / sec, with a bowden extruder and a direct drive. The 20x20 rail showed no vibration with the bowden or the direct drive. I was contemplating going with a 20x40 x arm but I think the 20x20 is rigid enough.

 

How much Eccentric Spacer you use and which size?

 

Nice build. Looks a lot like this one on Kickstarter:

Minimalism is at the heart engineering. I'm not sure I've seen the sweet spot for this type of machine yet, but I like this build. I'm not convinced the bowden tube can handle flexable filaments. That's a bit of a drawback. Nice build though, I'm gonna have to do something like this soon.

 

Show me a printer or extruder manufacturer that claims boldly that they can print flexible filament with a bowden configuration at anything above crawl speed. I've not seen one.

 

Yeah, I wasn't speaking specifically about this build. Just the bowden design in general. That's the main drawback I would weigh against its advantages. Probably worth it though.

 

adamcooks found another that looks even closer http://www.openbuilds.com/threads/h-bot-corexy-cube-with-fixed-build-plate.1528/page-2#post-16816 (https://www.kickstarter.com/projects/deezmaker/bukito-portable-3d-printer-take-it-everywhere).

Supposedly semi-flexible filaments like SemiFlex from NinjaFlex (http://www.ninjaflex3d.com/products/ninjaflex-filaments/) will work with Bowden - I will probably try some with my printer when I complete the build. To support other extrusion alternatives I am also still investigating a compact direct drive geared extruder or a cable driven extruder for a fourth extruder option.

 

Definitely appreciate the minimalistic approach as well...

 

This built talks to me ! I like the minimal designs like this. And your diagrams are really clear and clean. Maybe I'll try to make it but since I have no built to my curriculum for now, I'll start first with a small E-Waste 3D Printer using CDs and Floppy drives mechanisms saw on Instructables. Seem a good and cheap start to me !

 

This looks sweet, really tempted to give it a try, quick question on the hot end, does any one know if the "Quick-set Hot End Kit and Loom" from RepRapPro will be a simple drop in?

This be the one im looking at hehe........

Apologies for my un-knowing, one assumes you mean the "Bowden Hotend" (referring to the technical drawings) when you mention the X-Carriage?

P.s, the tech drawings - Fantastic! brings back memories hehe.

Edit: yep Im the dumb a**. they are in the tech drawings, Labelled 3
