A lot of work, but worth it By Alan C Reiner

A lot of work, but worth it By Alan C Reiner 

Getting the hard to stick filaments to STICK... no questions asked!! 

I just spent quite a bit of time battling the Taulman 618 Nylon filament. No matter what I did, it would not stick to the build platform. Now that I figured it out, it works like a dream. I removed a star for the moisture issues, the amount of work required to print with it reliably, and the extreme contraction it exhibits making it difficult to do anything precise. But it still gets 4 stars because it really opens up the printing possibilities once you have it working.

To get the Taulman 618 Nylon filament to stick, I did the following:

(1) Buy some canvas: http://www.amazon.com/gp/product/B000WFT9Z0
(2) Get some epoxy: http://www.amazon.com/gp/product/B0002BBV46
(3) Get something totally flat that can replace or be attached to your build platform
(3a) If you add something to the build platform, make sure you add something of equal thickness to the part of the printer that hits to the Z-axis endstop. i.e. if you add one inch to your build platform but don't also add 1 inch to the endstop, the machine is going to ram the board into nozzle and push an extra one inch past where it should go.
(4) Using the epoxy, glue the canvas to the flat surface. Try to make sure you get the epoxy all over the board without gaps.
(5) Relevel the build platform, but make it a slight bit tighter than you normally do.
(6) Set your print job to 240-245C and print!

By leveling the platform a bit tighter than usual, you are forcing the first layer of Taulman 618 Nylon filament to extrude into the threads of the canvas fabric, giving it a stronger grip. Somehow, I was able to print a medium-sized piece at 40% infill, and it stuck! And even better, I was able to remove it with my hand when it was done!

Also, as others have mentioned, the Taulman 618 Nylon filament needs to be really dry. If you leave it out too long in moisture, it will feel really soft and bendy before it goes into the printer. It feels good, but it's not ideal. You'll know that there's too much moisture if you hear popping sounds and see steam. It's a little concerning at first, but it really is just water boiling and escaping from the nozzle. I don't have a good system for removing the moisture, but I have been able to print some things with slightly moist nylon anyway.

The Taulman 618 Nylon filament is a highly-recommended print material if you put in the time to get it to work!

Robot Track System Lawn Mower Build Pt: 1

RoBO Lawn-Mower So, I work at our church on the grounds team and my job is to use a push mower on the VERY steep hills around the main building; I would say there is about 2 acres of this extreme hills that need to be mowed every week. Whew... it's pretty rough sometimes!! Of course my inner-geek always comes out while I'm mowing and I think of how I could make it easier... well, what about having a robot do this for me!!

But what sort of robot could manage these hills and do a GOOD JOB of cutting God's grass... hummm...

I have been doodleing and drawing for about 6 months on this and finally started building last week!!

Here we go...



I had a small push mower that I had just bought so I was going to use that for my platform and started researching what sort of motors are best for robots and battle robots; and found that wheelchair motors are awesome work horses.

I found some on eBay for the Jazzy Pride 1 wheelchair, perfect!! I also found …
