I should ask a help: I should calculate the size of the printer profiles in order to have a 'print area of 400 x 400 x 500 mm (xyz), can you help me? thanks a lot Beppe

 

Hope its ok, but I decided to share some pictures and changes I made to this design.
Compared to my Makerfarm 12" i3V, its much larger. Its set to print a volume of 400mmx400mmx400mm.
Take a look and see what you think. The most notable change was to move the z axes to the sides, off of the x carriage to avoid z banding.

 

Great design! I don't know if I'm missing something, but I was looking at the cad files and couldn't seem to understand how the 2020 pieces attached to the X gantry plate for the universal extruder mount.

I plan on building one of these soon!!
Thanks!

 

Marshall the C beam version is awesome! I can't see from the pictures but I'm assuming your X axis is going to be leadscrew driven as well?

also wondering if you could give us an update on how it worked out with the spindle for milling...

 

Here are some pictures of the print quality for those wondering what this design is capable of. I had to twist the drive belts at the idler end of both the X and Y axes. The machine is so ridged, I was actually getting some "ghosting" from the belt teeth running on the smooth idlers. I ran a z wobble test to see what it would do all the way up to the 300 mm mark. Looks real good. I have a 400mm silicon heater on order, so for now Im just printing on blue tape.

 

Nice prints! Almost all of the parts for mine have arrived, these pictures made me even more excited!

 

Love the build! Simple and rigid. Ever tried using one motor to drive two screws on the z-axis? It's clear you don't need to since you have some awesome prints, just thinking about doing a similar build with one z-axis motor.

 

1 z motor would work fine depending on the size and weight of your x carriage and beam. Mine is about 470 mm long and I will eventually run duel extruders so 2 will give me a little more head room. Also keep in mind that running the auto bed level feature will work your z motors harder than without.

 

Love the design and I'm looking to build one next month myself! Have you tried any dual extruder set ups for this? I'm concerned that the size of the gantry plates could never fit 2 extruders without too much sticking out, and thus limiting print size.

I'm also considering doing a horizontal x carriage using 2x pieces of 20x20 v slot for the axis, so that the hot end can sit between them for a bit of a neater configuration. Will try and get some drawings up here at some point to show you what I mean

 

Love the c-beam for the frame. I'm sure there is much more rigidity. I was curious about whether your X was screw driven as I was worried about speed. Now, to convince the Mrs. that I need to start ordering parts soon.

If space is a concern, you can always try this option: Cyclops/Chimera (Dual Extrusion Hotends) | Filastruder. I've never used either one but I'm finding the idea interesting.

 

I have considered the Chimera, but to be honest the limiting factor is the extruder. I've opted for direct drive, but even then 2 nema 17's take up alot of space. I've considered a bowden set up but I havn't found a decent solution to the backlash, if there even is one.

 

What open build plate is used to mount the motor to the back of the X axis? because it really doesn't show it and the .step file doesnt help all that much.

 

According to the parts list it is Threaded Rod Plate™ for Nema 17 Stepper Motor.

 

I printed the extruder in the project files because my current one doesn't mount the way I want it to, and was wondering (this is probably an extremely nooby question) what hardware is needed? Which bearings was it designed for (Nvm, I think you intend to use the wheel bearings), and what hobbed bolt should I use?

Thanks! I have built every part of this printer, but don't have an extruder yet for it. It seems incredibly awesome, I'm using an Azteeg x5 mini as a control board with 1/64th microstepping, and this thing is INCREDIBLY quiet and seems to be super accurate.

 

Really do want to build this one. Gonna just buy 5 20 x 80 x 500 mm and 1 20 x 60 x 500 mm and start from there. Where did your get you extruder. I have no printer to make one myself.

 

Find someone to print it is the best option. There is usually a local makerspace with a printer. If not, use a direct drive extruder such as mk8 which has the the hotend with it, or buy the adapter plate for an E3D. You can mount the motor directly to a gantry plate with mounting holes on the motor, or buy one of the metal motor brackets off ebay.. They only cost a few quid

 

Finally have my voxel OX up and running. Would recommend this build for sure. major improvement over my prusa i3 that it replaced.

Overall construction went smoothly, aside from a m5 tap brea king off inside my Z rail. ended up building it with 3 wheels on one side but for 3d printing I can't see it making a difference.

Extruder is direct drive Dyze, a new canadian Manurfacture that I decided to try out.. really great design had no problems at all.
Dyze Design DyzeXtrudeur for 1.75 mm filaments

I also used a printed Y motor and Idler mount designed by Sonny Lowe for a different project.

Quick question. Does your BOM include parts for the Wade extruder?

 

Question withdrawn. I finally figured out how to open the drawing and look at the parts.

 

Im working on a remixed version of this great design. mainly changing to one Z stepper and moving acme screws behind the gantry to maximize X travel
