CR-10 Ultimate Y-chain MK2: Y-axis drag chain for bottom mounting

would it be possible to create a bigger template for the drilling card ? maybe a template that wraps around one edge (knob area) with a hole where the knob goes to hold it tight of the Y carriage, that way it wouldn't need measuring. Really want to make this mod but would rather have a better template.

Please show me how to place the hole drilling card because I don’t understand what to do

What mods would be needed to make this work for the cr10 s5? Anyone done it yet?

I dont think it can be edited very easily. I'm sure some parts of the design can be reused, but basically every mounting point is different for the S5. It would nee a full redesign.

95% of my prints are failing due to layer shifts after this mod is this happening to you guys?

I see no reason why this mod would cause layer shifts. If you did everything correctly, drag in the Y should be similar or less compared to stock.

Common reasons for layer shifts are a loose grub scew on the pully or a loose belt. I would check those.

I wish I would have seen this mod before I did the control box delete on my Tornado. Everything is wired up on the same side this sits. I mirrored everything along the Z-axis and will do the mod this weekend. I'll be sure to post a make!

This is an amazing design, you have made something truly brilliant here. U don't suppose you have an X and Z one in the works that utilises that same cable chain, I see you have a Z one up already, but using 3D printed chain. Great work, will be printing this soon to go on with my Tornado overhaul.

By the way, I'm very interested to hear if it all fits on the tornado. Be sure to post your make!

Thanks dude! I think for the Z chain my design with the printed chain is fine. The Z chain doesn't move that much compared to the X and Y. There will not be any noticeable wear. A advantage of the printable chain is that i could connect the first and the last chain link onto the housing instead of using a mounting system. Personally i think a C drag chain isnt a great idea. There is no need as the braided sleeve does a great job already. A drag chain could add friction and vibration to the X axis, and only over complicates things.

Sweet! Im not entirely sure your Z design will fit the Tirnado OOTB, but ill give it a shot, i did a lot of looking ariund at pucs of each of our y carrages gowever, abd i di believe they are the same, and issues ill tweak and let you know. I jist ran out of PETG, so ill get a start on this as soon as my order arrives.

As fkr the X, my issue was the cables hanging down and sventualky interfearing with the prints, but right after my cimment, i found a little bracket that holds it to the side near the extruder, so i di believe that ussue is solved :)

Why design it with a chain tray instead of just a chain?

Because i dont think chains like these should be printed, and i do not like placing the chain on the side of the printer sticking out the back.

Why can't the stock cable be used?

because its probably less then 1/5th of the length you need

Hey Kristiaan, I am planing to make a stand alone restructuring for my printer, I was planing to design a control box and a drawer under the printer. I wanted your opinion. Do you think it is possible for mo to raise the chain tray to the extrusion level? Would it squeeze the chain?

I'm afraid that wont fit. There are drag chains that have a smaller radius, but i dont know if there are drag chains that have a radius that is small enough. If you choose to use such a dragchain be aware that the cables might not like it.

Thank you for your answer, I really like this and want to implement to my stand alone printer. I can design a work around for electronics with extrusions. Would be okay to share your CAD files with me?

Hi, very nice design!
Do you think it can be merged with this thing: https://www.thingiverse.com/thing:2764920 ?

CR10 Portable

Thank you!

I dont think those can be compatible. Both would need a full redesign as both the dragchain and the electronics mod are mounted in the space under the Y carriage. I guess 1 side of the printer should be used for the electronics, the other for the drag chain.

Anyway, personally i dont like the idea of the electronics sitting underneath the heat bed. In a enclosure this would put a lot of extra stress on the components.

Yeah if the enclosure is designed to full cover the printer then yes it will be a problem with extra heat, but if is designed/mounted at frame height IMHO it will be fine. I really hate CR-10's big noisy box and the stuffed cables that are a nightmare to arrange, they are too long or too short...
