New Mobious Robotics sE1X designs.

z brace_v1.1

So the last week or so I have been working on a few different CAD projects, lets dive in!

 

Okay for starters, let me remind everyone that all these will be available for download on our github page, linked here: sE1X Github Page

First, I started out with some new corner brackets for the sE1X, which will allow for 40mm more movement in the X axis which results in getting the full 300mm of available heated bed you pay for.

The new corners offer a TON of rigidity and strength to the lower frame assembly and are a great replacement for the metal corner brackets(which you can still use with the X axis upgrade if you wish..) and will soon be a standard part in the sE1X kits. It is 2 parts which makes it easier to print and no filing nec. for fitting..these will slide right on. Just requires 4 t-slot nuts and 4 M5-10s.

Second, to accommodate the larger X axis design, I needed to lengthen the Top X extrusion on the gantry. So I created a extrusion extension:

sE1X Extrusion Extension

Again, 2 parts for easy printing and is plenty strong. Simply cut the extrusion in half and add this extension in the middle and your ready to roll!

Thirdly, so with all this enlarging going on..I decided that some better support is needed for the gantry, so after much trial and error I finally designed a excellent support system. Using 2 150mm 2020 extrusions and some support brackets, the gantry will now have MUCH more strength and rigidity which I believe will result in not only being able to handle higher speeds with less vibration, but overall resolution and quality to your prints..

I am very pleased so far with the new gantry support, took a lot of work but it paid off in the end!

Ok last but not least, the original Y axis smooth rod holders gave me grief as well as a recent customer. I decided some new, stronger ones where needed ASAP! So here they are:

These will simply slide on and lock into place using 2 m5-10s and 2 t-slot nuts and will offer much more support to the Y axis smooth rods.

 

As I said above, all new creations will be uploaded to the Github page so please check it out, and keep checking back for new designs! Thanks!

Nylon printed wades gears on the sE1X!

sE1X Z and X assembly finished

So lately Beardedbuddha has been working with Nylon (Taulman I believe) on his sE1X and has recently had some great success! He originally received ABS gears for his Wades extruder which turned out to wear very quickly on him. So, he decided to replace them with nylon gears and the results are very impressive! Good Job beardedbuddha!!! 😀

Here is the ABS gear wear n tear and proof that ABS is not a good solution for gears as it tends to be softer then PLA. From now on we will only be printing the gears in PLA/Nylon and currently in the works, polycarbonate.( https://lh3.googleusercontent.com/ZNVqwiCUjbAvHxyc8sM8wQ4G2pVxd3KUSgRbi0TOfGc4=w1390-h1031-no )

New fully printable corner brackets for lower frame!!

Okay so I have managed to come up with a pretty solid corner bracket here. I cut the top off to make it a some what easier print while still maintaining its strength. I also added some recessed slots for m5 thin nuts where you can use a m5 screw as a set screw to hold the extrusions in place. I will continue to keep my updates posted here and check back soon for more!!

(06/20/15)UPDATE: So I decided to make it two parts so its easier to get on as well as offering more stability with a brace across the center of it to reduce and give. I’ve included a picture of the lower frame assembly with the new corner braces!

P.S.  A newly improved, 10mm and 8mm X carriage coming next which will offer more support for the Wades extruder and allow clearance over the top gantry. 🙂

sE1X printing in Polycarbonate!!!

275c HE / 120c HBP

As promised, the sE1X can fully handle the beast known as PC. The only issue has been with adhesion but from what I’ve read, kapton tape is the best way to go. In this photo, I used just a strong concentrate of ABS juice which worked ok until I got to the layers above 10+ where the part would then peel away from the heated bed. I will post more when I have tried it out on kapton.

sE1X delivers results!

se1x_2

Here is a recent print off a sE1X I wanted to show everyone how well they print. I am currently using 1.75mm ABS from Atomic filament.

The bridging work on the shroud is stunning..the smoothieboard 5xC runs flawlessly and the Hexagon has put out some fantastic prints. I am really proud of this 3d printer and cant wait to see what else she will do!!

More to come soon!!
