I'm looking at multi toolhead options right now for my 2.4. This looks like a great solution! Looking though the macros, are you using includes to enable or disable a printhead to keep klipper from have a panic when you remove one?
Yes, But also, I am using a macro called `[gcode_shell_command]`, which is an extension that can be installed with KIAUH, to swap in and out the printer.cfg. It just got finished today, and I just pushed it out as of this comment.
@@jace055 I am actually not too familiar with CAN bus and the terminologies around. Nevertheless, you can fine my wiring diagram here: github.com/VIN-y/MissChanger/tree/main/STLs%20and%20Instructions/v1.0%20-%20MVP
Nicely done, one small recommendation, adding some inrush protectors before the plugs would be a good idea now. (in the distribution board) plugging and unplugging them frequently will ablate the contacts.
I like the direction you are going. I'm planning something similar, but not similar. Just the concept. The execution will be very different, but I've used some of the ideas you have already, and enjoy seeing the ideas that differ. Can't wait to see what you come up with for a finished product, as this seems to be mirroring ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-lwFKDuF7oC4.html. Like, eerily similar.
FreeCAD hits soon version 1.0 at last, and they done a lot of work in development version now. But if you had worked in FreeCAD as it was before, you are a superhuman = ) I tried FreeCAD multiple times and have no luck. Only in development version I kinda understand how it all works = ) So I waiting for stable 1.0 version to start using it. = )
Nice work! I have to do the docs for my toolchanger design now too. (Since I have it printing nicely with 2 materials now). ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-9IsZiHBQRe4.htmlsi=uLbcH8fKsLdfAOvG
Tapchanger has a single mechanism for both probing and tool-changing. MissChanger separates them. The probing is done with the MGN9 rail that is attached to the gantry, and is used for all tool-heads. The tool-changing is done with 4 x 3mm pin-&-sleeve.
Great to see an update on this project! Freestyle is good if it means more updates :) With the new mechanism attaching using z movement, what would the docking station / tool holder look like for the 2.4? Keep up the great work!!!
hei its an awesome project and i think i want to try too contribute maybe i could hel you with buyng some filament and some coffee to chug along, i also have a 2.4 and i would realy like to use a tap compatible tool changer fully reversable
I've noticed you're using contact pins for the Heater/fans/thermistor. Just a few questions. Once it disengages from the system won't it cause an error because the thermistor is not connected? Also, For multi-color/multi-material... Won't this make the hotend fan stop working while the hotend is still hot? Causing Heat creep and possible clogs? Overall looks INSANE. Please update us soon!
the pogo pins are only for the tap sensor, everything else is connected through the canbus umbilical. Therefore, everything on the toolhead works as normal regardless of whether it is dock or not.
I do not think that printed parts will be sufficient for big prints with thousands of toolchanges... look at the E3D motion changer or a machine that was derived from that (Makertech Proforge 4)... I really think something like they implemented is needed... I also heard of the prusa XL being inconsistent with the toolchange or even fail the toolchange completely at one point... I think there needs to be a strong, self centering coupling system that is highly repeatable... maybe you could use a lighter electromagnet instead of a servo
I'm gonna follow this quite closely. I'm super interested in making a toolchanger machine but, despite the brilliance of the TapChanger, I find the the DragonBurner toolhead way too limiting cooling-wise on my V0. So a toolchanger that can keep the Stealthburner is exactly what I am looking for! Side question, what's the size of your 2.4? Is it a 300 or a 350?
Amazing video, it gives me hope in more open source multi-material/color open source 3d printers, I think it would be a great idea for you to have a patreon if you dont have one already, I think many people with vorons or may want to build one as myself would want this mod to be out for the public and would consider very much helping you to develop this great mod!
Awesome, great job that will absolutely cut down tool changing times, because i am currently planning my next build and also trying to add speed to it, one difficulty is it to move up and down with a heavy gantry
Awesome work, and THANK YOU for being willing to share it in its early stage. It's going to allow both better feedback back to you to improve it, and allow others to learn from your own work for their own development. Really cool stuff, excited to see it develop.
@@vinny5915 If it was stationary, could you add multiple of them and double or triple the amount of toolheads? or would the print interfere with the the tool change?
@@thecamarokid4230 Just to clarify. This docking system is not stationary, it is attached to the gantry and travel with it. Nevertheless, there are stationary dock design in the Tapchanger repository, which (theoretically) can be doubled up.
@@vinny5915Yup yup. Just wondering. I do like the design. Having it move up and down with the z axis will probably make the tool changes a lot quicker right?
Thank you for your great work! Cutting time of z movement as in tap changer is really significant, I’ll try to add helpful input with the published design 👏🏻👏🏻👏🏻
This is awesome, great work! I'm glad you started to release these, I don't have a full size voron to test with but I'm building a salad fork so maybe this can be shrunk down for boop!
