E5s1 inspired by Merc1

[vagrant root]

I decided to try and make my E5s1 a mercury but found some remixes during my decision making process that I am going to use. Some more custom parts will be needed for sure since not too many E5s1 - mercs are out there.

Remixed Mercury 1. I am using the front stepper mounts for my build

Rear stepper mounts moved on top of the frame: https://www.thingiverse.com/thing:5430682

Evantis toolhead. I am using basically the original and there are newer revisions but this is what I am using:

Hoon rails mod for E5s1. I keep mentioning this, and I used the MGN alignment tools from this kit:
https://www.printables.com/model/505869-ender-5-s1-linear-rails-kit

Edge of 3d alignment tools. I dont think the tensioning tools are valid anymore and Im only using the extrusion squaring tools:
https://github.com/ZeroGDesign/UserMods/tree/main/Mercury_One/Rudra

I started out with wanting to the Hoon rail kit so I orded in my MGN12s. Then I was thinking about it while driving around one day it dawned on me that I have rails, klipper, and extrusions kicking around. Thats most of the way to having what I would need to corexy. That of course led me here.

I also have a Rapido UHF that I had bought when they first came out and never used. So that made sence too. I'm a big fan of pushing more plastic instead of more speed so cooling had to happed and the S1 had one 5015 already so I ordered in some more.

after digging through the user mods channel, I found the Evantis toolhead and was on board almost right away. I like the set up of the Mantis toolhead and having it already configured to run on this build was perfect. I'm not sure I like the location of the bed probe in there, but I'm going to try it out and see how it goes. Im going to put a sherpa mini on top, but I'm waiting on screws to get here first.

I also want to use this remix from @tall marlin but I cant use the entire thing because his is designed to hold the MGN directly and I'm going to keep the gantry extrusion mostly because my 300mm rail wont fit all the way across.
https://www.thingiverse.com/thing:5438468
I like the motors up front though. So hopefully his design can work for me. If not, it should be really close and easy to find a solution. On top of having less pullies and in turn less friction, they also make it so I can put a top enclosure on it much more easily.

i believe he said that the stock x joints work i believe. also might want to post a link of the remix

[vagrant root]

thought I had, sorry

Spent some time today getting the tool head sorted out and test fit on some extra extrusion I have. Now that I know I have all the right pieces and everything lines up, I can comfortably say it's ready to go.

Printed these gantry alignment tools from Eo3D

And these mgn alignment tools from the Hoon rail kit. That's just where I grabbed them from, they are hundreds of them floating around

after talking with @tall marlin about his design and another one he did prior, Im going to use the front motors from the link I posted before, but instead of those idlers, Im going to use these stepper mounts he did previously as a stronger idler set up. For those interested, this link is designed to move the motors on top of the back corner giving 3 points of attatchment to the frame and make itenclosable easily. I'm not doing that, just using them as my idler blocks.

[tall marlin]

Nice. looking forward to seeing the build. If you need some help, let me know!~

[vocal kestrel]

do you have the link to the STL for these?

[sharp sequoia]

I believe it's this model, https://github.com/ZeroGDesign/UserMods/blob/main/Mercury_One/Rudra/X_Extrusion_Squaring_Tool/stl/X_Extrusion_Squaring_Tool x2.stl

[vocal kestrel]

I found it by rewatching the video

[vagrant root]

all links are in the first post

[vagrant root]

Between the smooth face of the 5s1 and the front steeper mounts, I needed a different belt tensioning method. Messaged @tall marlin and he wipped up a design that is part the tapped extrusion plates and part matching his stepper mounts. No links for this because he sent them directly to me..... and trust me you don't them the way he sent them. I had to edit out some embossing that wouldn't be allowed on some servers. Lol

[tall marlin]

Bwaaaaaaaaaahaaaaaassa

[tall marlin]

I will make them more generic and post to thingiverse. Actually, I should re-post the setup you use. It confusing to use rear mounts for one thingiverse link and other parts for another. But they were intended for other reasons.

[vagrant root]

hold off on that. I'm keeping a running log of everything so that a 5s1 remix can be assembled

[vagrant root]

So it's been a few days since I updated. Not much has happened progress wise. But I have been working with @raven hound to develop an adapter bracket to hold the sprite break out board for Evantis toolhead.

This should make it much easier for sprite machines like my E5s1 to convert.

I'm not 100% sure on this piece yet because I haven't actually tested it in the machine. But all my test fitting has gone well. One it's actually tested and ready I'm sure @raven hound will release it as an optional part for his toolhead.

[vagrant root]

started last night with taking everything apart and starting the build. Its been a little bit of figuring out to get this far because I'm using different modified versions together, but I think I might be pretty close to having it sorted out

I need to figure out endstops still, but I think I can manage that loosely off the stocks and the ZeroG set up

[vagrant root]

everything is hooked up and plugged in except the steppers. Turns out the steppers I have use dupont connectors and not jst. I dont feel like cutting and splicing them especially since I need the dupont connectors on my cnc build.

I need to work on cable management still but that can wait until I have the motors in

[vagrant root]

fans tested correctly, rapido tested and calibrated correctly

I need to figure out the sherpa's motor config and see what I get there. End stops tested correctly. Motors are ordered but I tried to get sneaky and plug in some old anycubic motors I had laying around. FAIL lol

E5s1 Merc1 trying to keep factory parts

[vagrant root]

it moves

not correctly, but it moves

[vagrant root]

ok, everything is wired up and homing on all 3 axis. Just need to tell kilpper how to work the new extruder but my brain hurts so I'll have to do that tomorrow. I'm done for the nigh

not sure if that counts as printing, but its getting close

E5s1 inspired by Merc1

I was told that this is too different from a mercury1 to get a serial. So I have changed the name of this build so that there isnt any confusion.

Awesome printer @vagrant root, however, this doesn't look like a Mercury One.1 so we cannot issue a serial for this machine. Good work though!

not angry or anything and I'm not leaving or causing a scene. I just don't want anyone to follow my build thinking they are going to have an official mercury one.1 when they are done.

but if it cant be a Mercury One.1 then I will still give credit where credit is due..... its inspired by Mercury

[tall marlin]

I can get you a serial # no problem. Where are the test prints and ADXL readings?

[lavish pollen]

Did you end up going further with this? I found it interesting.

[crude yew]

indeed both idler and stepper towers are different, I wonder how you tension the belt. I found it interesting as well

[obtuse sluice]

the motors are the tensioner

[crude yew]

so you pull the entire motor tower to tension the belt?

[obtuse sluice]

you can see in these images. #1200481619987939409 message

[crude yew]

that looks nice! thanks, I wonder, if the belt is reversed, how a slightly modified stepper tower could still have a pulley to grip the belt (and getting a 4 motors merc 😛)

[obtuse sluice]

idk if the belt path is the same but i believe it is. @tall marlin can confirm. but in theroy you can do a 4wd merc with these. i have thought about doing an awd conversion.

[tall marlin]

Yes, the belt heights are the same. AWD possible with this for sure.

What is tough with the mercury 1 is the typical 2020 frame. There is not much room for the stepper motor mounts and they really need to be more rigidly mounted.

[crude yew]

like with the metal stepper towers?

[tall marlin]

Plastic mounts are not really good. What is better is to use a plate on the top, bottom and standoffs in between + plastic. This way the heat from the motor goes into the aluminum, no worries of heat creep and very rigid. But with 2020 extrusion it's not really wide enough unless you capture bolts on the left extrusion and another bolt on the front extrusion for a total of at least 3 bolts.

easy to make the plates by hand or have SDS make them for you.

[obtuse sluice]

well good thing @surreal elm made metal steppers lol
