A1 Y-Axis Heat Bed Drag Chain (Cable Chain) - No Offset & No Sagging

 

I wanted to make a cable chain that is good looking, functional and is easy on the cable.

• The offset problem is solved by designing an S shaped offsetting base to the heatbed to shift the position of the cable.
• The sagging  problem is solved by making 10 of the bottom chainlinks only bendable upward and the rest of the links till the top freemoving in both direction. This way the cable is not touching an tapping the table.
• The heatbed base is fixed in position with the printer's own screw. You just have to screw and unscew it with the small hex key.
• The bottom base is designed so it fits snuggly to the printer but optionall you can print the screw-on version. For that you have to drill two small holes on the printers back with a Dremmel Tool. Mine works perfectly but do this at your your own risk. 

Important Assembly Steps (also check photos): 

1. Start from the bottom: Add one of the drag chain base options. One for the fixed triangled printer version, this can be just pushed on or screwed on. And 3  version for A1 printers that comes with a removable plastic triangle or bump. Here you should remove the triangle or bump to have space for the base. If you use the screw on version add two pieces of bt3x12 self tapping screws. And put the cable chain fixer inside the housing so that the screws have a solid block to grap into.
2. Add the bottom part links (the ones that can only move in one direction staired end end long back) alternating as seen on photos.
3. Then continue with the top part links (the ones that can move more freely round end and short back.)
4. Before adding the last piece, screw out the one little screw with the little hex key.
5. Place the base. Push and bend the cable in place.
6. Add the last link piece.
7. Screw back the little screw.
8. Check if everything is ok by pushing the bed back and fort by hand.
9. Done!

I printed mine with PETG but PLA works fine aswell. Although since the top base is quite close to the heatbed I think PETG is preferable.

 

ENJOY!
