A1 Z-Axis Drag Chain - V2

Please read carefully! This is a working prototype. Use this accessory at your your own risk.

For the main part that connects on the x motor house, there is a version with a extruder cable chain connector and one without it.

ASSEMBLY:

Bring the extruder to the lowest Z height.
Click the side box into the grooves. You can use some double sided tape betweeen the box and the printer too.
Close the back of the side box with the extra hinge part.
Bring the extruder to max Z height.
Add the main part to the motor house. Slide it from the right then add scews. 4 pieces of M3 (min 5 max 12mm) You can srew on the bottom part first if its easyer for you. Also here you can add the first link since its easyer to snap before tightening the screw fully.
IMPORTANT: Start assembling the links from the TOP while straithening the cable until you reach the bottom. The links direction must be alternating to hold the cable and to have a good curvature at the end. Use all (min 13) links but if you need more lenght you can just print individual links.
Test if the bending of cable is good.
ENJOY!

I Printed this with Bambu Lab - PLA Basic - Light Grey (Same color as printer main body)

Awesome design I love it, I love all 3 of the chains, I have printed all 3 and the A1 looks so much better now, specially because I printed them all in red PETG and it just pops.

beautiful! thanks!!

can I ask what is the print on the left of the print bed? thanks

Har du noget om til slutning på dette billede?

The design is fantastic and clearly shows a lot of effort! However, I instantly noticed that when the z axis is fully lowered it bends the cable at about a 130-degree angle, causing my black shield to splay out and leaving a small crease in it. Although overall this curvature is similar to normal, the snug fit leaves little room for the cable to naturally flex, forcing it to bend around the corner. My main concern is that this could damage the internal cables over time, so I’ll leave it off for now. While the lower portion didn’t click in perfectly (would have just put some 3m VHB to hold it) and the L bracket needed some filing, those are nit picks compared to the perceived cable damage risk. There’s enough slack on my cable with about 1-2cm left of play however the sharp bends do worry me for long-term use. I really love the design though, and would like to use it if you have suggestions to reduce the pressure on that one spot?

Yes I followed the instructions (top down), and referred to the photos for chain orientation, printed with sunlu pla+ using your profile. Your photo also shows it pulling around the same corner/angle that I was concerned about

@user_3958794390

Hello, I did it differently. I turned all the open sides to the back and only put a small cable tie on the second and penultimate link. This way, the chain cannot block and the cable does not have any tension towards the back and has space.

Replying to @arzhanglotfi :

Thanks, I spent a few hours today testing different orientations (including the suggested one) but I’m not sure how they achieved those bends without the outer links popping off. Even after modifying mine for more flexibility, facing them outward like that still led to issues. Have you modified the chain at all since a few days ago? Anyway I'm happy with the fit now! If you don’t mind, I have a few of suggestions: Changing the inner ChainC/D joints to have a 45-degree angle instead of 90 could smooth out the corners a bit and reduce stress on the cable during bends. I basically de-burred my edges to remove the corner. Adding a similar angle to the outer edge of the 'chainC' links would improve backward articulation, Ive sanded mine down a little which allows greater articulation. I noticed the new side box with the original 'L bracket' replaced with the 'side box extra part', but my modification of cutting the overhang off and rounding it off seems to give the cable more freedom when exiting the side box. A larger U channel might also help on your new version too? Just my thoughts/observations—feel free to take them or leave them!

Best design I've seen! Awesome job to the creator! Printed with matte PLA, I think one chain link broke during install, no biggie. Looks good with my Fallout 4 tinkering.

@quirkyturtle

pictures of assembly would be nice if have two parts that I have no idea where the go the the bigger part doesn't stay put either

The designer has replied

@quirkyturtle

Replying to @arzhanglotfi :

can you please share pictures? I tried to click the bigger piece at the bottom it absolutely doesn't stay in :/

@arzhanglotfi

Replying to @quirkyturtle :

hi! sorry im not home to make pictures as im on vacation. Please check the others and mine photos. Everything should click and slide together.

@quirkyturtle

Replying to @arzhanglotfi :

it definitely doesn't only one notch clicks into place the other doesn't why not include pictures of assembly when you make a files that doesn't make sense....

@GalaxyRiver

Thank you for this; it's something that should come with the A1. Some feedback. 1) (Edit - sorry, missed the hotend drag chain link in your description - thanks!!) 2) When XYZ control is put to max Z and "home" is then pressed, the side drag chain is not long enough and slips a link somewhere as the X-bar is taken a little further up. 3) I printed in PLA. The top bracket seems too tight on the A1 and I cracked it putting on, not necessary to be so tight as you have screw fixings. See photo for where break occurred. 4) I couldn't push the main bottom piece fully into the Z-axis upright so sticks out a little proud. 5) Lots of support needed during printing. I'm guessing it could be optimised a bit, especially for the big bottom piece - instead of having the bottom link connection sticking up, maybe change the design and have it connect lower so that the large bottom piece can then be printed the other way up and far less support needed? (I used PETG as support interface material for PLA print and it worked fairly well.) Thanks again for your work.

@arzhanglotfi

1) yeah cool 2) Sorry Im not shure if I understand but if I get it right you might have a shorter chain then me. Also you should try disassemble then adding the chains from the top to the bottom that way there will be more playroom. 3) Sorry to hear. mine works but i adding one soon with a bigger play. 4) I made it like this by design but i made it a little closer. I will upload soon. 5) Thank you for this tip. Good point. I will upload it in 15minutes. Also I made it more hollow to save even more filament.

@arzhanglotfi

Sorry. Updated now. Last time somehow it didnt uploaded. Thanks!

the bigger piece that is supposed to click into the printer doesn't fully click in also the chain is extremely stiff when it reaches 0 on the z axis the chain just snaps off the part that's supposed to click into the printer. Also asked for pictures of assembly because I had 2 parts that I have no idea where they went because there isn't assembly pictures. when I asked for pictures I was told to look at other people's printed pictures..... file creator wasn't very helpful.

@quirkyturtle

Replying to @arzhanglotfi :

another thing that should be in the description that isn't. Photo's of assembly should have also been included when they file was uploaded.

@user_339483855

It really is completely self-explanatory where these parts have to be fitted. You only have to look at the shapes and then there won't be many possibilities where these parts fit - to be precise, there is exactly one possibility for each part where they fit. What's so difficult to understand and why are you acting like a Karen here? Here - I uploaded these photos just for you.

Great design! I wish there were some room for excess cable, otherwise the bottom part just moves away from the printer. No biggie, though!! I needed to add support to some parts ;)

The bottom can click in in place. Thank You for rating my model! :) If you like it, please push the BOOST button. Thats the way creators get points for their work. Also please follow me if you like my stuff. Thank You!
