New Gantry produces promising results

DSC00513

So far I’ve been spending quite a bit of time calibrating my newly rebuilt gantry design. I want to get more testing time in on it before I release it to the public, so that I know its not going to give anyone trouble.

When it is released, customers with the previous version will have the opportunity to upgrade their gantry’s to the new design. I will be putting together a tutorial on setting up the new designed gantry system along with links to the STL’s needed to do so.

Thanks to everyone who has hung in there and continued to show support for Mobious Robotics LLC., it is very much appreciated!

New sE1X gantry design underway!

by: papabur

I have been working on redesigning the sE1X Z/X axis design in solidworks so that the Z axis motor will be placed at the top and make for better printing with less hassle. The current design(by tjb1) is great and it works well but can be a bit difficult to get assembled and requires quite a bit of filing which nobody likes to have to do.

In my previous post I submitted a link to a article by Protoparadigm which talks about Z axis motor placement and why its better to have the Z axis motors on top vs. on the bottom.

So far I have gotten about halfway done with the new design and from now on I will be posting updates along with photo’s of the CAD progress. I spent the day working on making a assembly in Solidworks with the new Z axis top motor brackets which is posted above.

I will post more as soon as I can, this is my top priority right now so expect to see it finished soon!!

Accuracy vs. Precision and Threaded Rod vs. Leadscrews

protologo

So, after reading a very informative article about motor placement in regards to Z axis, and being tired of the current design, I’ve decided to design a new Z/X Axis system and the first big change will be having the Z axis motors mounted on the top(Will be in separate post).

For now, the new design will be made for 5mm threaded rod(same as what we currently use) but I will also be making a version to fit ACME lead screws. Lead Screws will offer much more precision and accuracy in the sE1X print quality and less hassle down the road as threaded rod has a tendency to get bent..

I will be making all the STL’s available on the github page for previous customers to update their current sE1X’s Z and X axis. If you would like to read the article that made me decide to tackle this project, link is posted below:

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!

sE1X tames the beast known as Polycarbonate!

DSC00410

So after much trial and error, we finally found what works for adhesion when printing PC! 😀

So with the heated bed set to 120c, some kapton tape roughed up with sandpaper, and a thin layer of ABS juice, we’ve managed to get great adhesion when printing the beast, Polycarbonate and will hopefully be able to start offering polycarbonate printed parts with our sE1X kits!

Hotend: Hexagon AO

Temp: 285c (bed@120c)

Speed: 40mm/s

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!!

New sE1X corner brackets

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!

Github link to sE1X files: https://github.com/papabur/sE1X-10mm

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. 🙂
