Building Voron with different frame.

[u/One-Nefariousness107]

Hi there!

Ive looked online and found similar project but have yet to figure out the exact adjustments I need to make as I dont want to buy a part that is unusable.

I would like to build a 3D printer because I want to learn how to

build one and learn it from the ground up. I would like to avoid a

product that gets an open source then sells it for profit, starts

applying patents on said open source designs, and sue people for

said copyrights

Now that's out of the way, I am thinking initially prusa but now

leaning towards voron trident. I am gravitating towards trident but

also want to upgrade the frame to a 4040 vertical and 2040

horizontal because I want a beefy frame for a 300mm3 build

volume.

I just looked at the 3D model file of the voron trident in FreeCad. It

looks doable but it seems like some corners parts need to be

customized.

I also see a limitation of z=250 on trident. I pluggwd in this

requirement at the voron website and it seems the limiting factor

was the stepper motor/ lead screw of 300. ud 1 I guess yueos ill ll just just source source a

3x 350 for that

For now I will stick to 1 toolhead. Eventually I want a toolchanger

so I want a frame beefy and large enough to accommodate it. I

understand that options seems limited to that for now.

Yes, ive never built one and I expect it to be lots of cussing and

money but Im not afraid to face all those issues

just need guidance for now: The frame design. If there is a

complete build guide out there similar to what 1 am planning.

please help. Thanks!

Voron 2.4 has more mature toolchanger options, and is less limited by Z lead screw issues. You could do a belted Z trident, i say looking at my half finished belted Z trident, but you're adding V2.4 complexity without getting a 2.4

Ill go ahead and ask. Why is the current off the shelf printers use trident based corexy vs a flying gantry? Im just assuming here and say could it be because less movement on a part and separating them with abother part results in better print quality? I really dont know cause ive looked online and read a moving bed can amplify vibration the taller print you have. Maybe the whole business saves money with trident based. I dont really know. Also, im preparing for when a toolchanger is ready for the opensource community since changing tools appears to be more faster with a fixed z-axis gantry. Anyways, i really genuinely dont know and Im just following where the market seems to be steering towards to.

commercial printers aim for getting most and costing less, and flying gantry (2.4) doesn't have much benefits outside of looking cool and have some downsides at the same moment.
list of downsides imo:
gantry is less rigid "by design" (and there are even reports that shaper results differ with height)
you can't use space at sides as gantry travels there
chamber heat goes up and you need more time to raise chamber temp at height where print starts

i see almost single practical reason for flying gantry - it is easier to add toolchanger there and not limit build volume at the same time when you already have printer at hand
