First try with flexible filament

I decided to purchase some sample flexible filament to see if my printer could handle it without any modifications.  I decided not to go with the Ninjaflex as I would most likely have to modify my extruder (bowden style) and tube as it might be too flexible.  I ended up going with the Sainsmart brand….just purchased some clear off of Amazon.

All I did was turn the heat up a little (205 deg) and slow the speed down to 30mms.  No heated bed on my printer…just did my typical glue-stick and I am highly impressed with how my prints came out!  I started with just a hexagon shape just to see what would happen and then got more adventurous with an iPhone 6 case.  Came out amazing!  Ended up going with 3 layers on top and bottom and 2 layers for the shell.

Only problem is…I don’t have an iPhone 6…=(  I am sporting the Samsung Note 4 currently (I’m an Android guy at heart) but couldn’t find anything on Thingiverse that looked like a good print for this and it would take me forever to design my own.  Going to take these cases in to work and have some co-workers give them a try.  Might post an update.

3d Printed wiper sprayer

Thought I’d make a little post on a 3d printed part I just did for my van.  The wiper washer broke on the driver’s side blade and just for kicks, I searched Thingiverse to see if someone had designed something similar and someone did!

I printed one out and with a zip-tie to hold the hose on, it works pretty decent.  It seems to shoot the spray right at the blade but at least now it’s not flapping around like it was before.

P.S. this is for my 2006 Chevy Uplander…in case anyone is interested

Update on the tessel arm

Figured I’d give an update on how the tessel arm has been coming.

I have since purchased a 3d printer kit…which was a little pain-staking to get going but now that I’ve got it working, I definitely know it pretty well…which was the point.  I mentally prepared myself for the trials of getting it working and am continuing to learn still.

Using the 3d printer, I’ve been using a guy’s design and tweaking it as needed.

Here are some pics.

I’ve got it using pretty simple gcode right now.  The software is going to be the kicker for this.  I will end up having it work pretty similar to 3d printer to pic things up and move them.  I’d like the software to be pretty intuitive to the user, drag and drop “locations” and loops to handle tedious tasks.  =)

A buddy an I went in on a 10 pack of some 84oz/in torque steppers….and those things hold pretty well.  With the motors engaged, I can pick up the whole thing by the end of the arm and it doesn’t budge.  =)

Will post more as I progress.  Time for this is short but still fun to play with when I can.

Delta 3d Printer Build (He3d DLT-180)

So I sold a few other things and ordered the cheapest delta 3d printer kit I could find. It came in and took a bit of learning curve… but that is the point when you get into 3d printing, isn’t it? =)

First off, my stepper motors were wired incorrectly. Thanks to the help of those into he 3d printing community, I found I could just play with the wiring till I found out what worked. It did help that I had my little tessel board already programmed to play with a stepper.

Once I got the wiring corrected the motors were still extremely loud when moving. Finally a user on reddit mentioned I should check my jumper settings. Jumper settings?! I just assumed the firmware could do all that. Guess not. Of course, the kit I got was missing all the jumpers needed. Between some help from my awesome neighbor and some old computer drives I had laying around and was able to get all that I needed (12 in total). Once those were in, no more shaking and buzzing! Still not done though.

After scouring through the G-Code wiki and reading up on the firmware that I had (micromake) I found the key setting that I really needed to tweak was the z-endstop-offset. Using the “paper test” that many refer to, I was able to home that setting in. Then came the fun of learning how to load filament in this thing.
