Solved my vertical speed problem. Stealthchop starts skipping steps at 40 for some reason. Spread spectrum + 48v goes up to 300 with no sweat. Tool mount: github.com/vie... Wiring harness: github.com/vie...
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.
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
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)
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.
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?
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
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.
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....
@@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?
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.
@@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.
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.
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.
@@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.
@@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.
