Reprap: Print Replacement Parts for Household Items

Looking for something useful to do with your Reprap?  I used mine to fix a couple of nagging issues around the house. First, one of the rubber feet on my Vitamix blender had gone AWOL a few years ago.  It actually balanced fine on 3 feet, but after I got my Printrbot working, it was […]

Case Protoype for LeafCAN

I’ve been having a lot of issues tweaking my latest Reprap design, so I haven’t been able print a case for my LeafCAN SOC meter.  Late last week, the printer was stabilizing, so I took a break to whip up something in OpenSCAD.  It’s just a basic box, which I printed in natural ABS.  I don’t like […]

Reprap: Don’t Throw Away Your Cracked/Weak Parts – Fix Them!

Sometimes, my layers don’t stick nicely, or I print a part that’s too thin, and the part cracks between layers when I try to use it: There’s no need to throw them away and reprint them.  Just use a q-Tip soaked in acetone and paint it liberally.  Junk ABS bits dissolved in acetone works even […]

Did Termites Eat My Print?

I was printing out the x-end-motor for a new Reprap I’m designing yesterday. The bottom was printing beautifully: I baby sat it for the first 2:15, and went to bed during the remaining 15 minutes of the print.  I woke up the next morning to find this: At first, I thought my hot end had […]

Raspberry Pi Case

I was not fast enough to get an order in for a Raspberry Pi on launch day.  Fortunately, a kind friend of mine thought of me, and bought an extra one for me.  I received it yesterday, and printed this case: The case I made is a copy of HansH’s excellent Raspberry Pi case, modified […]

Marlin for Printrboard Updated

I just synced my Marlin branch for Printrboard with the latest code from ErikZalm’s branch. I noticed that there were a lot of changes in the planner, temperature control, etc.  Hopefully, it will be an improvement, rather than breaking anything.  Please report here or on github if you find any anolmalies with the new code. […]

Printrbot Build

My Printrbot from the Printrbot’s Kickstarter Campaign was supposed to arrive in February. Unfortunately, due to the huge number of supporters they received, the schedule has been pushed back, and I doubt I’ll receive mine until late May. In the meantime, I’ve been getting antsy waiting for mine to arrive, so I decided to go […]

grbl CNC Firmware Ported to Printrboard

If you want to use your RepRap for CNC use, such as milling PCB’s, regular 3D printing firmwares might not be ideal. For instance, Marlin is not able to handle the slow step rates used for CNC work. I have ported grbl, a firmware specifically for CNC use (from which Marlin derived its acceleration routines), […]

Repetier Firmware Now Runs on Printrboard

I spent this past weekend porting Repetier-Firmware to Printrboard and Teensyduino. It took me a while to get it working properly, because the code intermixes calls to fastio and Arduino, and the pin definitions in fastio.h were different from the Teensyduino Arduino library. It is now working pretty well, so Printrboard and Teensylu users now […]

Running Marlin Firmware on a Printrboard

As of this writing, the official version of Marlin firmware from github does not yet work with Printrboard.  Printrboard is a fork of Teensylu, designed by the folks at Printrbot. Printrboard isn’t yet available for purchase, but since the design is open source, anyone can download it and get the PCB’s manufactured themselves. Sprinter is currently […]
