Question: does this still allow the Ender 5 S1 top cover to go over?

looking at converting to core xy anyway you can design the belt clamps for that use?
loving the mod tho have about 500 hours of print on it and have yet to as any issues after i fixed my bed spacers

what speedups can be achieved with this project?

For those who get all the way to the end of this project, and discover that they still don't have enough bed travel to reach the nozzle...

Loosen the coupler between the Z-axis servo and the threaded rod and add some gap between the rod and servo shaft before re-tightening. It's an obvious fix in hindsight, but it took me a day or two to think of. :D

@grnbrg_563658 or just print thicker bed spacers.

@TrentonPhill_1092784 Thicker spacers don't help when you run out of bed screw, and there are no exposed threads for the adjustment knobs to grip, and the nozzle /still/ doesn't touch the build plate.... (edited)

Overall this project is amazing. Great job o the guide and bom. I used very cheap rails off AliExpress they were like 12$ a piece. Cleaned them with ipa and packed them with superlube grease. I did spend a bit on hardware from boltdepot. Came out great. No more Pom wheel dust. I have the full enclosure with the lid and I can confirm it does fit with this mod installed. I printed in green petg 5 walls 40% cubic infill .2mm layer height.

Also, I have the NBR board and I had to make extensions for most of the cables. I ordered a mx1.25 pre crimped kit off Amazon for the extruder. (edited)

After probably a year of looking at this, I finally pulled the trigger! Getting all the screws was initially a pain, then I just gave up and bought some kits from Amazon. Spent more than I had to and now I can do this project 20x more! The actual build took a day or so and still tinkering here and there. Thank you for such a well laid out project. The BOM, instructions, and images were awesome!

This was a pretty big/new project for me. I'm mechanically inclined but mostly with car stuff. At the end of the day though all you need are tools and a willingness to buy a new printer (or car engine or whatever you're working on)! I learned quite a bit on this project. I used the MGN9H and MGN12H rails, and because I'm impatient, I printed just about everything with a .6mm nozzle, .28 layers, 4 walls, 30% infill, 60mm/s using PETG. The biggest problem I had was trying to figure out the best support settings for some of the bridging. I also had to cut one of the lugs off the fan that was hitting the x end stop...took 2 seconds.

Seems like it's humming along well. When those dual fans kick in it sounds like a hair dryer! The attached benchy photo is the first print with the new setup. It looks so so, but, again, I'm impatient, so I just grabbed a spool of PLA sitting out in my humid garage for months and used the same settings for the PETG parts with a different temp. So considering all that, I think it printed a pretty good benchy in just 26 minutes. Here is a clip - https://youtu.be/F3wCb7-SriU

Only one minor issue/question... On the x axis the printhead moves smoothly when I manually move it but I feel a little more resistance about 2/3 of the way to the motor. It's not a binding feeling, and everything is aligned. I also don't see any print issues. Any thoughts on this?

I'm happy to help anyone if there are any questions about my experience.

Thanks again for such a great project. Arlen.

@arlen_2178829 Not sure about the resistance issue, maybe a belt rubbing issue? Regarding the fan noise, I actually run mine slower than full speed so it’s quiet but with adequate cooling. Nothing wrong with full blast though for even better cooling lol. Also the type of fan makes a big difference in noise. Great write up and glad to hear you enjoyed the mod and thank you for the accolades!

@Hoon_781548 Thank you... Seems like I fixed the resistance issue. I think it was just slight inaccuracy in the alignment tool. I just cracked open the rail bolts and let the print head smooth it out, then tightened from the center out. The fan sound is actually kind of satisfying but for PETG I'm barely running them.
