- 'WP-DAKSH' Voron Trident 3D Tool Changer is a fully 3D printed tool changer compatible with different CoreXY platforms like the Voron Trident, 1.8, 2.4 and RatRig VCore 3.
It features state of the art advanced features including:
* Reliable tool changing mechanism powered by a single servo
* Servo Burnout protection for enhanced life and efficient tool changes
* Intelligent Error State Detection and Recovery minimizing failed prints
* Automatic XYZ calibration across the different tools
* Ultra Fast tool changing times of under 10 seconds
* Capable of High accelerations and print speeds
* Minimal loss in build space with the tool changer addition
* Integrated nozzle cleaning mechanism for clean prints without the need for a purge tower / ooze shield
* 4x4 LED Display on toolhead to display the current state of toolhead
* Custom Klipper configuration, modules and macros for an integrated software package
* Stiff Wire Looms and recoil management like Prusa XL - wire looms are contained within the printer frame itself.
* Stiff Wire Looms and recoil management like Prusa XL - wire looms are entirely contained within the printer frame itself.
* Fully Enclosed Design in the same design ethos as the original Voron Trident design - giving it the ability to print high temp materials like ABS, PA6-CF and PC-CF etc which require enclosed chambers.

thanks - new videos coming soon.
I just finished your latest video, awesome job!!! I have wanted a tool changer for a long time and have been following your progress videos. Congratulations it looks amazing!!! ......awating eagerly the source file drops.... 8-)
Thanks - the next videos in the series as well as the files are just around the corner.
Heeey!!! I'm looking forward to watch all your videos in these series! Glad you decided to make them!
Thanks much - glad you like them. Stay tuned for more...
Thx so much for sharing your incredible work in details! Looking forward to learn more for the whole series of your video.
Thanks for watching!
This is amazing, can't wait to see more!
thanks - will push out new videos in the build very soon.
It's a great system for the Trident.
With a ERCF tool head for "occasional colours" this will be amazing.
Absolutely - thanks much
Awesome video! Can't wait for the files to drop to check it out in detail.
CAD Model + Firmware + Updated Files for Dragon Hotend and Docking system released. many thanks to @edcasati for his efforts in building the Fusion 360 models for the community to use. - github.com/ankurv2k6/wp-daksh-toolchanger
Thanks for the video, its great. Kind regars from switzerland ❤❤
Thanks much.
This is really great man, im planning on doing my own design for one, but if that doesnt work i may just go with building one of yours. ❤. Thanks for going through all this trouble for the community, youre the type of person that keeps this hobby rolling forward! 😊
Good luck!
thank you for sharing the information and very inspiring.
thanks much - really appreciate it.
Its extremly cool and a very nice update for me Voron 2.4 r2 350 (in work).
We have a new version called DAKSH BOLT which is an addon that attaches to the front -build specifically for printers like the 2,4. Please look in the discord for more info.
I love this system's design and it is definitely going to influence me to get a voron soon. Do you think it would be possible to rework the system a bit to have it work on the 2.4? Possibly have all the tools stored way at the top and the gantry can return to the top every time for a tool change?
Yes, absolutely - this should be compatible with mot of the corexy platforms - but will need some modifications.
Loving this idea. I hope that version compatable with Voron 2.4 is in the future. Would love to add this into my belt print bed machine.
I have project that involves swapping to a 0.2 nozzle for the last 2mm of layers. Not requiring a manual nozzle change during the print will be amazing and let me switch to printing in ABS.
I have ideas around adapting this to the 2.4 - with the new V2 mechanical tool changer. That will be next once the V2 is completed
@ankurv2k8 can't wait to see more.
I really like this implementation of multimaterial in the trident. I have a couple questions. Can you provide a ballpark figure for just the toolchanger in regards to cost? Trying to exclude the cost of a stock trident as I already have a one and I am looking to upgrade it to have this capability. What speeds are you currently running with the setup like this? As in, can you keep stock voron speeds or do you need to run a system like this slower?
Hi - please check the newer version of the tool changer - its fully mechanical and more sturdy than V1
This is exactly what I've been searching for! Nice work!
What would you estimate build costs at?
Thanks - its essentially a trident build + about $75-$125 per tool depending on the hotend used. Add in about $200 for the extra parts in electronics and wiring etc.
Great Job. I think this is a great Project. Do you Think about a Carrier with one mgn12 rail instead of the 2 mgn9 ?
The 2 MGN9 was a requirement for the original woodpecker - my design of the WP-DAKSH variant uses a single MGN12 instead
Thank you for the great work.
Some questions:
- Do you use CAN for the toolheads?
- Why is the probe attached to the cariage? Wouldn't it be better to mount it to the least used tool, as it's only needed for leveling before starting the print and is a useless weigth afterwards anyway? (for allother tools you have to find out the xyz-offsets anyway)
- Also the servo is only used for unlocking the tool, if I understand correctly. Could'nt it be replaced by some sort of longer lever and a servo next to the tools parking lot, pushing the lever? (yes it means you need one servo per tool - but you do not carry the servo...)
- If I understand correctly, you only use printheads. There are other tools possible, like pen, pick&place, cutter (but I do not recommend laser on open frame printers). Also the part cooling might depend of the printhead you use. Wouldn't it be better to attach part cooling to the tool instead of the carriage?
- As with the points above the only remaining electrical component is the endstop, this might be moved to the x-axis. So no cable to the carriage and no cable chain needed.
Just some ideas.
Thanks for the appreciation - in reply to your questions.
1. I am upgrading to EBB36 with TL TCHC hotends - but will be using USB instead of CAN on all 6 toolheads via a powered USB hub
2. The probe weight is negligible as compared to the toolheads and makes for faster homing/tramming without having to pick up a toolhead.
3. Servo is used both for locking and unlocking the tool - the current design requires a servo to be present on the carriage - there could certainly be a way to use a servo per toolhead - but the current system is so reliable that i am not looking to modify it. There are other designs out there that are exploring a servo less system - you can find more details on the DAKSH discord.
4. The part cooling can certainly be moved to the tool - but my requirement was to fit 6 tools in the limited frame space that was available and maximize the Y travel. You can attach the part cooling fans to the front of the toolhead.
The design is extensible and can be modified to suit your requirements as needed - the current design is as per my specific requirements and is working very reliably - with a less than 8 second toolchange sequence.
Danm! Now I've got to decide between an IDEX and a tool changer! Unless... 💡
there is a new version of the toolchanger - please check it out.
Hi there, nice work. What was the weight of a complete head? is it possible to modify the carrier as I have 2 mgn9 and 2020 carbon fiber, up/down. Also the docking station as I have 3030 profile.
Best regards
M
Thanks - have not weighed a tool actually - so cant give you a definitive answer. The docks can be modified for 3030 without much issues - and the toolhead should be doable on the dual mgn9 - infact the original woodpecker build from MrBean was dual MGN9. But i have modified things so much that you will have to use the CAD (to be released shortly) to modify the latest iteration as per your use case.
@@ankurv2k8 thanks for the reply. are the step files available for download? modifying myself, is no problem.

@@mh-laser2886 The CAD files will be available shortly on github
@@ankurv2k8 thanks
Is this marlin or klipper ?
This is based on klipper - also V1 has been superceded by V2 which is a fully mechanical tool changer
@@ankurv2k8 I was planning to integrate this to marlin 5 axis firmware , so i guess ill change to klipper but 5 axis on stable klipper firmware ive never looked at it even ...i ll try .4, thanks for your answer .
What size printer do i need for 6 tools, thanks.
My build is a 350 x 350 trident frame which fits 6 tools on the back extrusion. But the frame will need to be about 75mm deeper to allow for the use of the full build plate in the Y axis.
@@ankurv2k8 I have a bare 350 voron frame, how much Y would i lose eith this build?
Thanks for your reply, amazing work btw!
Edit: i mean you did say 75mm deeper but I mean does that include some wiggle room or will my 350 become 350x275
@@davidbinenfeld489 i am getting 320x280 on my build - the loss in x is due to the 90 degree rotation that i did with the belted z. I dont think there should be any loss with a leadscrew build in X as long as the leadscrews do not collide with the xy joints or the carriage when rotated 90 degrees
I might actually look into the other belted z designs that other members of the community have come up - they might be better than mine at avoiding the loss of build space in X
@@ankurv2k8 I might not be able to build my voron soon but I'll try to figure something out myself to minimize the loss of build volume
Do you have contact? I want to show you my 3d printer with tool changer
Hi - sounds great. You can contact me on discord if you dont mind joining the discord server for the daksh-toolchanger. The link is in the description above.
