My first 3d printer: A journey of not burning my house down and having fun.

A journey of not burning my house down and having fun.

3d printing has been in the news the past few years. I have been wanting one for quite a while (my first post was about 3d printers)

I ran across a great sale on, where you can get a Sixth Gen Prusa i3 kit, it starts at $255 USD and has some nice upgrades that don’t cost to much. I purchased the larger build area and the auto level sensor.

It uses a Marlin compatible board that can easily be flashed with the Arduino IDE. In order to get better prints, I was able to find on a forum the right settings and a guide to upgrade my firmware. Also enable some of my feature and make some tweaks. I like the openness of even this kit, I have made some upgrades (you will) read about them bellow. And this unit is quite flexible. I spent sub $500 and I have feature that some of the $2,000 models don’t have yet.

And so it begins!

Some parts were damaged in shipping, but I was able to glue them together/tape. The nice thing about a 3d printer is you can always print new parts! If you happen to have the same printer as I and need the STL files here they are.

So it begins! So it begins2!

Coming together

My initial setup, I used a old Lenvo tablet to be my main printer. I used Printrun (Pronter) as my first 3d printing host software. That has since changed. You can read more bellow.

My Setup

Inital upgrades

Before and after I started my first print I did some minor upgrades. First thing I did was go buy a good solid 3 pin AC power cable. The one they sent was very cheap, and had no netrual/ground. So before I did anything with the power supply I went to Homedepot and picked up a good one. I also changed out the gage wire to a thicker one.

First print!

It took a while to get my first print done, the tool chain was a pain to wrap my head around. I use Cura 15.02.1 as my slicing software. Then I had to find a good print host software. Its not as simple as open STL and click print. Even though commercial ones I hear it is.

This was a calibration cube printed in ABS. Not very good bed adhesion. I have since gone to almost 100% printing PLA, just easier to work with. I want to enclose the printer, but due to the frame being acrylic; I worry about warping.

First Print!


So this is my first big project where I put something together that has a power supply. I did some upgrades as I went along, putting in thicker gaged wire then what came with my printer, since I could feel the wires outside plastic coating start to get soft on the original cables.

So after I put in thicker gage, it was hard to get a good connection. But it was good enough, or so I thought. I learned a valuable lesions that night about current AMPs and resistance; and about listening to my wife when she smells burning plastic.

What seemed to be the issue was I did not have enough of the cooper touching the connector. So the contact surface was poor, which caused resistance, and heating of the connector and the melting, smoke and almost fire.

But I was quick enough to turn it off and there was no damage to the components or the PCB. But that connector was fried, so I removed it and attached a new one/better one. Have not had a heating issue or connection issue since then. Did many, many hours of printing with no issues.

Fire damage... Repairs start...

Last Upgrades (for now…)

I did some upgrades and put a Raspberry Pi as the new print host, I am using OctoPrint. I cannot say enough good things about this software, its simple to use. I just drop my GCODE files into the browser window. Then I click print! Fantastic, also I have a Wi-Fi dongle so now my printer is wireless. On top of that I bought 24v to 5v USB adapter and wired it up to my printer so I only have one power cable.

I have as much fun and enjoyment upgrading and learning as I do printing. My kids love what can be done. They had a mustache day at school and I forgot. But luckly for me on Thingiverse there was this neat mustache made by Microsoft (I know right?). I printed a few out for my boys to use and share and I heard it was pretty cool.

Current Status

So this is the current status of my printer, I made a mod to get closer to the set screw to tighten it up and well it kind of ended up doing the opposite. As of this post, that’s the status of my printer. I have yet to work on getting it running, even thought its only 15 minutes of work. But my day job has gotten me pretty busy as of late. I hope to get back to it soon.

Repairs start...

I love 3d printing!

See above!

Also, this kit was pretty cheap and is not a out of box experience. But if you want to have a cheaper decent quality 3d printer and learn and upgrade things at the same time. It maybe the printer for you.
