IGUS drylin Y-axis upgrade for Ender 3

thingiverse

EDIT: I previously updated the parts to a new Version 2 because of some issues I had with them. Hi Makers! This is an upgrade for a much stiffer Y-axis-carriage on your Ender 3. This is built on a standard Ender-3 but I guess it should work pretty well on an Ender-3 pro, too. The main reason for this upgrade was the fact I was not happy about the wobbly bed of the Ender from the first day. On your stock bed you can push down any corner very easily. Even if this will not be an issue at all, I did not want to live with that and figured out a solution. What you have to get: 450mm of WS-10-80S https://www.igus.com/product/732 (without holes) 1pc of WW-10-80-15 https://www.igus.com/product/933 1m of any GT2 timing belt, e.g. https://www.amazon.de/Anyasen-zahnriemen-Riemenscheibe-Umlenkrolle-Inbusschl%C3%BCssel/dp/B07ZGLQXVZ/ref=sr_1_3_sspa?__mk_de_DE=%C3%85M%C3%85%C5%BD%C3%95%C3%91&crid=II3VERUS5APG&keywords=gt2+zahnriemen&qid=1577306542&sprefix=gt2+%2Caps%2C182&sr=8-3-spons&psc=1&spLa=ZW5jcnlwdGVkUXVhbGlmaWVyPUFQNjhQSUMwT0JPTUUmZW5jcnlwdGVkSWQ9QTA3MjM1NjAzTU9LS1JNNUdJSTE4JmVuY3J5cHRlZEFkSWQ9QTA4NjYxNjczQlhKSFdLRFVaUEFaJndpZGdldE5hbWU9c3BfYXRmJmFjdGlvbj1jbGlja1JlZGlyZWN0JmRvTm90TG9nQ2xpY2s9dHJ1ZQ== 6pc EU-20-M5 fasteners https://www.amazon.de/gp/product/B075WVP4S8/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1 If you want maximum stiffness you want to get 250mm extrusion as you can see in my pictures to set the IGUS-rail onto in the front. This is not necessary and can cause problems if you do not install it in a proper way. I only suggest doing so if you are able to drill precise holes into your original extrusions. You will also need to place your mainboard-case to the back of your printer. https://de.banggood.com/Machifit-100-1000mm-Black-2040-V-Slot-Aluminum-Profile-Extrusion-Frame-for-CNC-Tool-DIY-p-1342020.html?rmmds=myorder&ID=515968&cur_warehouse=CN And some bolts and washers in various sizes from M4 to M6. Sorry, I do not have any documentation about them since I had them lying around. You'll figure it out! While everything is beeing shipped, print the parts uploaded. I printed them with PLA and 100% infill for stability. You will have to drill holes into your IGUS-rail as shown in the drawing attached. You will also need to drill 4 holes Ø6,5mm into your Y-carriage-plate to attach it to the new IGUS-slide with the original M6 threds found in the guides of the silde. Place the carriage on top and mark the spots for the holes. Drill one hole M6 into the slide since you will not be able to fit the carriage plate to all 4 existing threads. Also drill 4 holes M3 into the middle of either side of the slide to attach the Y-Belt-Clamps. When all the drilling is done, put everything together as shown in the pictures. Put 4 of the M5 nuts into the extrusion to attach the rail to the existing frame. Measure to have it in the middle. Adjust the endstop to a proper position. Tighten the belt with the two bolts of the front belt-mount. You want to put the slide onto the rail first without the carriage-plate attached so you can loosen and tighten the bolts for the 4 guiding pieces of the slide. You will need to try a couple of times to get the slide move easily without beeing too loose or too tight. There is one configuration of the guides where this will be the case. It can take some time. When everything is built together, edit your firmware to the new endstop positions and you are done! Enjoy!
