Voron going fast ... vertically

- Solved my vertical speed problem.
Stealthchop starts skipping steps at 40 for some reason.
Spread spectrum + 48v goes up to 300 with no sweat.

Great system! Using the vertical axis of the tap for tool change is brilliant. Simple solutions are the best and the most difficult to engineer. I've just started to incorporate your system into my current Voron 2.4 build.
Nice job! It also made a huge speed difference for me when I switched from stealthChop to spreadCycle.
Beautiful, speed fixes everything!
i would definitely look into getting some of the steel parts made at send cut send, ultra cheap and you could get some fairly precise/repeatable parts. awesome work
Dude, that is just amazing. Maybe I will build one, for my Voron :D
I love it I think this made my decision on which one I am going to build. I was on the fence between the 2.4 and the trident, the tool head changers on the trident from what I see feed from the back (unless this can also be used in a trident because I still like the idea of a tiltable Z axis)
That's so cool. Good to see a tool changer on the 2.4. Gives me ideas to do this aswell
I'm not normally a fan of Vorons, but OMG wow that's awesome. I never thought of having the tools be the highest Z height. I hope you figure out the other 5 problems you mentioned.
Nice project!
This is a beautiful build
Idk what all this means, it sounds like some spaceship and that's very damn cool
I suspect you can probably push the acceleration higher! That sounds like the default, so a significant portion of the movement isn't at top speed. I have mine at least 5x stock (I forgot the exact value) and I didn't even have to push the current beyond the default 0.8A.
Will definitely build this when you are done, also volunteer for testing if you want
I LOVE that toolchanger, is it yours? Did you share it?
Edit ah I see the description, frigging amazing man this'll be the first big upgrade to my voron I think
Wow! That's fast.
what driver and board are you using sir?
what does your voltage look like on Z?
may i ask if that one magnet is sufficient enough to hold the tool head while printing in fast speeds?
also, have you tried doing prints with the multi tool head changes, was there any alignment issues appearing on the printed object?
Nice workout
Wow... Just wow
What type of endstop finally works the best on the voron? Thanks for the video. I'm planing to make the tapchanger mods.
oh my goodness gracious! my enders look like a toy right now......could this be the ultimate! it'll be so cool if I can build one...and that's A ONE BIG IF....
So, 24V and stealthchop disabled was working at 150mm/s? Did you try it with 48V and stealthchop enabled?
Hello, are you using can bus? if so, how did you chain multiple of them?
Cool. But all EBB36 are installed. How did you connect them? Did you all connect them with U2C? I saw your git but couldn't find it.
Yes all conected to a single u2c.
There is a canbus page in GitHub.
@@viesturz I'm curious about the distribution box. Many people only use one toolhead.
I've never seen multiple toolheads connected to U2C like you. Can I share the picture?
@@viesturz Sorry! I couldn't see the image on github yesterday, but I can see it today
Have you seen Josh Murrah's V2.4 with dd z drives and keybaks?
Are u saying U drive all Z-motors with 48V for better acceleration ?
It's cool but from a practical and complexity perspective the tool-changer is better suited for a moving bed / fixed gantry printer like a Trident or RatRig or VzBot
It depends. If I think about a Jennyprinter 650 (650by650by650), the bed is quite heavy. So this might be the better solution to add a toolchanger there. While there are printers with big size (like the Vcore 3.1 up to 500by500, I doubt any bed with bigger size should be designed with a moving bed.
Also it depends what you use the toolchanger for: Full multicolour, swapping tools multiple times per layer? Or just support interface layers (soluble support or PLA/PETG trick)? Or changing nozzle diameter after a certain height?
It does matter if you need 500+ toolchanges in a print or just maybe up to 50...
But you might thinking about adding two extra z-axis for the tool holder as an alternative solution. So the tools are always near the level of the gantry. If the mountain will not come to Mohammed, Mohammed will go to the mountain...
@@oleurgast730 I'd want a tool-changer to be efficient and work well in all situations... what you're proposing are workarounds for a less than ideal situation, not solutions or alternatives.
@@hd-be7di Why shouldn't it work well in all situations, to simply add an extra z-gantry to lift the toolbay accordingly to the xy-gantry on a Voron-style printer? A fixed bed has a lot of advantages, as thickness (and therefore weight) doesn't matter. It's a valid solution and alternative for thoose printers. Of course, if you have a smaler printer based on a voron 2.4-design and doing it just to keep your existing well working printer instead building a new one, you might call it a workaround. But for big size printers it's a solution, even if you develop it from scratch.
@@oleurgast730 I agree it can be a viable solution for some setups but not exactly ideal for the V2.4
@@hd-be7di Yes, but in my opinion you should say it the other way around: If you want to add a toolchanger, you shouldn't use a Voron 2.4 as basic design. Exept if you already have it and do not need another one or you have other reasons to use a z-fixed bed.
Esto ya es sacársela pero mucho....
Have you considered putting the extra toolhead rail on the gantry, so it's always at the Z of the toolheads?
You could even get fancy and seperate it on its own set of screw rods if you want to seperate the mass.
lol and ....those poor idlers
They will be fine, 4x slower than XY idlers.
@@viesturz I absolutely love what you're doing,do you have a patreon?
What stepper drivers where?
tMC5160 all around. RussianCatFood mentioned that for Phoenix he is using some cheaper 48v capable TMCs but I cannot find the model now.
@@viesturz have a Leviathan coming....its 5160 for ab
How does the Z endstop work on these?
Each tool can move up and down and has a sensor, same way as voron Tap.
The sensor is used to check if the toolchange was successful and also as a bed probe/ z endstop.
@@viesturz if you push too hard, won't the tool pop?
@@Hajtosek it can, in practice never has with over 20 hours of printing. The movement is constrained to exactly up on rails for the first 4mm, so normal XY jerk does not affect it.
@@viesturz Does this mod require the double 2020 extrusion in front of the printeR?
@@viesturz Whats your V2 size on the video?

Bambu printers are cool, Bambu fans are not.
sorry to bring this to you... but voron is quite a bit older than bambu
@@xav6427 That's the joke, Bambu fans think any fast core XY printer is a Bambu copy. In reality, if they want to think that way, Bambu "copied" Voron.
