You are right, now there are extruders that are much more efficient and lighter. I am working on a new version of the direct tool changer

@@Alex_Railnolds looking fw to it, cuz i also wanna make a toolchanger

This idea of ​​multi-color printing is not new. Bambulab has nothing to worry about :)))

You're mistaken. This has big problems, and it can be seen in the video. The problem was that I could not properly configure the cleaning tower in the slicer when I was filming the video.

@@Alex_Railnolds oh okay, i thought you avoided priming towers and tuned retracting/ramming ^^

Hi. The project is not intended for distribution. I'm not a professional designer and I'm not sure it's worth repeating my mistakes. There are some disadvantages to this method. What specifically interests you?

Дякую. Насправді багато людей роблять різні генератори диму. Це лише моє бачення для конкретної моделі. Плата керування - це моя особиста розробка.

@@Alex_Railnolds я також розробляв свої плати для мікроконтролерів Atmel для керування маленькими роботами (мізки+драйвери моторів). Замовляв тоді ще на київському радіозаводі (ви, мабуть, вже в Китаї ?) і розсилав нашому невеликому ком'юніті. Тому я розумію вас. Поважаю, тисну руку !

Hi. There is the first test print is shown on this video. Of course, to get the clean print you need to use wipe tower or nozzle cleaning system. Any of that are not showing on this video.

​@@Alex_Railnoldsdo you think that with very fast toolchange movements and a bit of retraction it could avoid oozing ?

@@alexiscapt5819 HI. I think no. While the tool head is on the docking station, even using retraction cannot guarantee filament loss. Especially when tool heads are changed frequently and they do not have time to cool down to idle temperature. I think physicall blocking of the nozzle will give a better effect.

Hi. Yes, I will make a nozzle wiper soon.

Hi. The printer is continuously upgrading, so all parts had changed now. What are you interested in?

@@Alex_Railnolds it just looks very sturdy. I just ordered 4 hemera xs for my tool changer. What slicer are you using?

@@brian2k1 I use Ultimaker Cura slicer.

Hi. I didn't use reprapfirmware configuration tool, I made my config by myself. It is too long to post it here. Try to see it - drive.google.com/file/d/14X3qBhzq1tQ7BBmX_-xvLP3iPZ-8WWXB/view?usp=share_link - this is my last configuration. Unfortunately, now my machine structure was changed, and now I back to servo tool changer and the configuration for the locking system you can see in this video was lost. You can see another video on my chanel with the last structure of my machine - direct drive toolchanger.

@@Alex_Railnolds Thank you so much!!!.... for your time and sharing your file I respect the fact that you didn't use tha reprap tool I think it will be a lot better for me to follow and understand your setup....peace!!!

It's a magic. 😀 The tool head is placed on the dock lower in 1.5 mm that the original position for full engagemened gears. When tool is selected the gears are not collide. The needed position of the gears is achieved when the locking mechanism is locking.

Hi. No, not HBot, it is classic CoreXY kinematic with crossing belts.

@@Alex_Railnolds Thanks for the answer! I've went through other videos and comments and now I see. I'm amused that belts don't rub against each other at the back/twist. Could you post a short with close up at the belts in the back? Thanks in advance.

@@piotrgrabowski2137 In generally, a single plane CoreXY schematic is classical. You can find more information and photos by the link - 3dtoday.ru/blogs/railnolds/kastomnyy-3d-printer-s-toolchanger. Also there, in the comments, some people interested the same question like yours, you can find there some photos and my description.

Hi. No, this is not a Black box. The idea is similar, but not the same.

Hi, Stephane. Thank you. I didn't understand your question about shipping, what you meant?

@@Alex_Railnolds hi Alex you are most welcome I understand this is a project to be build I see some videos on UA-cam that people have to print lost of part and that’s ok for me I already have a printer to print parts for the build What is not clear is does it come with the complete parts besides the ones needed to be print The power supply ,the cards for the drivers ,the complete cables sets,the screen ,the step motors or does it have to be ordered separately like the choice for the extruders I’m looking to order that printer with the direct drive option Have a nice day Stéphane

@@bruce12000 Hi, My printer is not serially produced. I designed and made it by myself. If you want to order the printer with toolchanger, you can find the E3D online shop and order it there. For example, here - e3d-online.com/pages/toolchanger

Hi. This idea is not mine. Jubilee 3D printer was the first.

Hi. More details you can find by these links: 3dtoday.ru/blogs/railnolds/kastomnyy-3d-printer-s-toolchanger 3dtoday.ru/blogs/railnolds/kastomnyi-3d-printer-s-toolchanger-cast-2-direct-drive-toolchanger Or ask Google about E3D Toolchanger. My system is based on this idea.

Hi. By default the number of the first extruder in Cura slicer is zero. But it can be changed if you need. I didnt changed it. Yes I saw the head with cutting tool proposed by E3D. Maybe in the future I will think about it.

Hi, Saint. Thank you. I have looked your videos, and I should say that it is an excellent job! Some ideas are interesting for me, I will take them :) Yes, you are right. I am not using the wipe tower and any anti oozing system now. I use Cura to slice the models, and in this slicer the wipe tower is used for all extruders the printer has, even if some of them are disabled in the slicer. I don’t know why, maybe I am not fully understood the settings. And I am not finished the anti-oozing system for my printer, I am thinking about it. Of cause, to get good multicolor printing, something should be made to avoid filament leakage from the docked heads. I didn’t see Prusa XL printer before, but I will see it, because you talked about it. So, now I can’t answer about possibilities of the Duet2 in heads calibration. I also do it manually.

Hi. The design is not ready for sharing, for example, like E3D project or something like that.

Hi. Thank you for your comment. In general, the tool changer is not my idea. The E3D proposed this idea few years ago. On the video you can see only my interpretation of this idea. It is a little different in realization, but the main idea is still the same.

Hi. Not too much. It is enough. :))))

Hi. It is just a cable from the bed to the board. I didn't use cable chain for it. Maybe later.

Hi. The temperatures of the heads are regulated by G-code commands, which are generated by special program - Slicer. I use Ultimaker Cura slicer to generate G-code. G-code is generated automatically, so you just need to set the printing temperature and standby temperature in slicer. When the head is on the dock, the head temperature is decreasing to standby temperature to avoid plastic leakage. Before choosing the head, the head temperature is increasing to printing temperature.

Hi. The tool is placed on the dock at a little lower level than the main gear (about 1 mm lower). After the locking mechanism locks, the tool is placed on the needed position and the tool gear meshes from bottom to top direction. Also, before locking the extruder motor is disabled by the script.

H-bot not CoreXY

@@Rasle500 0:50 Look behind the leadscrew. The XY belts get twisted and cross each other. It eliminates the need to offset the belts vertically and you can do a single plane coreXY.

@@robertgcode965 I stand corrected, thanks for the explanation.

Hi. Thank you. A 3D printer is a part of my hobby. As you can see from other videos of my "UA-cam chanel", my hobby is radio control car models. So, I use my 3D printer in generally for this purpose. But also of cause for printing other interesting things. In real life I am scientist. But solid modelling is also helpful for my scientific investigations.

@@Alex_Railnolds okay, got your channel recommended. Scientist in physics? I am a hardware developer at some photonic research institute. I plan also to build such a printer, I am used to Prusa, but I want to build my own.

@@maxhouseman3129 Heat driven cooling technologies

I use Duet2 WiFi, not original. It is clone from MKS. And also original Duex5 expansion board.

Hi. I have neve used serially produced printers, espesially with moving bed.

I guess every head is calibrated (distance to the head bed) by its own.

Hi. Each head is calibrated and the result of calibration is added to the firmware for each head separatelly as Z ofset. Also, X and Y ofsets are measured and added to the firmware. It is very easy to do, because the firmware is configured through the G-code commands.

Hi. Not need to track absolute position of the extruder motor, even at tool changing. The same extruder drive is set for all tools by the firmware. So, the firmware thinks that printer has only one extruder motor.

@@Alex_Railnolds thanks yes I've just seen your answer on a similar question I was thinking about the meshing of the gears and thought you moved the teeth to the correct position before every tool change

@@TheLordinio No, I use another method to avoid collision of the gears. I hope you found my explanation about it. If no, just let me know.

Hi. I didnt mesure the repeatability of the nozzle position, but visually no defects from tool change cycle. Defect are only because the filament leacking. As for as other sudgesstions - I will think, but maybe it is too complex to realize them on present dimensions.

Thank you.

Hi. I use Duet2 WiFi board, so the RepRapFirmware is used. This firmware is configured by G-code commands, so it is very easy to change any settings. As for the tool changing commands - all of them done like a script file with the command what printer should do at the instrument changing. From the slicer it just need the command like T1 or T2 with the instrument number to change the instrument, other the script is doing. You can find alot of videos in UA-cam about how to configure this firmware for toolchanger.

Да, спасибо E3D за идею.
