Another advantage of the printed plastic carriage replacing the metal part is that the weight comes down enough so the head does not drop anymore when the motors are disengaged (for me anyway).
Just noticed on the CoPrint wiki there is a page I have not seen before. It think it might be quite recent - was last updated 16 May '25 and thought I would mention it in case anybody wants to check it out. Seems quite software technical but the page is titled " Setup KCM Set Creality K1 and V3 Series" and then the blurb says: “There are some incompatibilities in Klipper for Creality K1 and V3 series. You can solve this problem by following the steps below;” https://wiki.coprint3d.com/en/Setup-KCM-Set-Creality-K1-and-V3-Series
Just when I thought my printer was working and my prints are beautiful again.
Never. It automatically levels before every print.
I’m thinking about buying the +4 extruder and the ECM. So far, this Coprint stuff has worked 100% for me. I make pictures with Huefor, and the +4 color would be useful there. I’m going to modify Frause’s method so that I can fit the ECM under the cover.
How long did it take to complete? How much fill did you use? It’s cool by the way.
I don’t fully understand this table leveling, for me it levels everything before printing. Can this be turned off? It doesn’t really bother me, it only takes a few minutes.
I haven’t printed for more than 16 hours.
I haven’t experienced any problems recently. The bed level is also good, I’ve never had a problem with that. I see one thing wrong at the moment, when changing filament, it pushes the previous one back a little, in which case the filament can go under the drum on the spool. My drum rotates on bearings. But this is not the printer’s fault. I’ll figure out some kind of spring buffer for it.
Normal multicolour prints work fine, but when I don’t want to build a huge wipe tower for a single colour change many layers higher up in my print and just put in a pause for a manual change, I get this behaviour too. It pauses as it should, I do a retract but then when I later hit extrude after changing filament it goes to the print and poops all over it, messing up the print. And there is no resume button, almost as if hitting extrude means resume and extrude.
Hi Guys,
I have the Coprint set installed in a regular Ender3v3. I got the kit on Preorder so when I received it there was not too much help in regard to the regular Ender 3V3 - just for the Plus. I ended Scratching a plate and spending, expending a few hours with a tech from Coprint who remoted in to help, and ended doing a few hours of AI tweaking the config files.
I am not sure if there are now official config files for the E3 V3 as I am somewhat happy with the current files I have, but I am happy to share them if someone needs them.
I understand that the firmware for the Ender 3V3 and Plus is the same. Everything is available here. Ender 3v3 KCM Set Setup Page | Co Print Wiki
You don’t need to modify any config files. At least I didn’t do anything. I installed this, reassembled it, started the Orca slicer, selected the printer, and that’s it. I modified the head carrier so that the printable area remained the original size, so I had to modify this in the config files, but nothing else.
I’ve encountered one error so far, but as I see, it’s the same for others. The error occurs when the filament runs out or when changing filament manually. In this case, the rinsing before continuing is performed on the printed surface, and this ruins the print. We haven’t found a solution for this yet.
Got my Ender 3V3 Plus + the CoPrint 4 color set today. Set it up with FW V1.2.3.63 and now it is kind of running. I have printed a single color object successfully so far.
The problem I am having is with the printer.cfg file. Without the printer.cfg update I always got error about not able to talk to nozzle mcu, and I saw the printer.cfg from coprint does comment out the part of nozzle mcu, so it makes sense. And replacing the printer.cfg with the one from coprint does work after klipper restart. However, my issue is that whenever I do a power cycle of the printer, the printer.cfg went back to the original version, and I will have to update the printer.cfg again. It is not a blocker but really annoying.
Hi Richard, If you meant to reply to me.
I tried connect KCM to the USB port directly as well as with a USB hub, no difference. And the KCM is getting power from the original Creality head cable.
Also, I just noticed something interesting this morning. After updating the printer.cfg, there was no error message, however, the UI on the enver display keeps rebooting itself. But in the meantime, OracSlicer has no problem of connecting to it to start a print. And even more weird, as soon as the print starts, the UI stops rebooting…
Yes, I wrote to you. Based on my experience, the USB hub can cause problems, it doesn’t work with all of them. It causes exactly this error. Secondly, I got a KCM set from coprint that has a separate power supply (quite powerful), and only later did I find out that the KCM set sold by Creality uses a converter cable to power the KCM. My idea is this: I think the Creality head cable can’t supply enough power to the new head, the KCM, and the 4 or more extruders at the same time, and I think this could be the source of the communication error. I would try to replace the Creality head cable with a more powerful power supply with the right voltage, and I would try with the original printer cfg. I completely disassembled that cable in particular. I can’t tell you offhand what voltage power supply is needed, I installed it in the printer housing, so I can’t read its data anymore, and I don’t want to say anything stupid. But someone above had this problem, and they changed the path in Fuid, then saved it, and it was fine from there. If you read back, you’ll find it. It might help you solve it.
I have one more question. Do you have a filament sensor on your filament distributor? If not, you may need the older 1.2.3.30 firmware. This is how it worked for another user above. Coprint KCM Set - #60 by Leo_Cavallo
Some learning result so far. I have no idea how you guys could get it to work without modifying something.
I tried to use the config files on the device under /usr/share/klipper/config/F002/color4 and my UI rebooting issue is not happening anymore.
In /etc/init.d/S55klipper_service, when Klipper starts it will update the config files. I have not found any code path that could copy the config files from what I found above, yet.
So I manually copied the config files, and commented out the “copy_config” from the Klipper service file. This part of change (the “copy_config” part) was inspired by the link from Coprint KCM Set - #82 by JJEX , but the rest of that page does not work.
Now the SW part seems be fixed, and next is to HW… I tried to do multi color print today, but it seems one of the input path in the 8-in-1 is not very smooth? I can see the extruder trying to extrude the filament but it just cannot pass that bottleneck and I had to manually take the filament out and put in again…will do more research later
