Hot end anatomy and dissection

Since the beginning of the RepRap Project, people have fought jamming hotends. Me too. And even though there were some rays of hope lately, I didn’t build the “jack of all …

Filament drybox from paint bucket

Most likely this feature was already depicted in a post about the Junkstrap or TronXY X5S: my hacked-together dry box for the filament. When the junkstrap got OctoPrint and moved …

Finallizing RosTrap (and discarding it)

Spending a few days at home I printed in the bedroom by day and in the kichten by night to get the parts together and finally re-build the mechanics. The …

Messing about at the status quo

As already posted the slides were in development. But for the rest: why reinvent the wheel? The Delta-Pi was already on Thingiverse and I choose to adapt to MikeP-NZ’s effector. Later I …

RoStrap gets floor heating

Under close supervision and with some restrictions the “RoStrap” was producing useable parts now – time for upgrades. The NEMA 17 Stepper Mount by ElectronicKit was designed for 80/20 aluminum T-slot …

Destroying and rebuilding the hot end nozzle

The metal sheet I used as a flat, machinable build plate was not the proper surface, so I attached a PMMA sheet, covered with polyimide, using bulldog clips (from the writing materials …

First prints – first PLA jams

The mechanics were bolted, glued and zip-tied together, the headers of Rostock-Marlin somewhat configured for the dimensions of my RoStrap, pronterface was able to issue some commands (move to X/Y/Z, …

Driving the base frame by means of CNC

After the mechanics seemed to work I invested into the CNC parts: NEMA17 (42mm) stepper motors and a motion controller. The three pulleys did fit (the fourth motor is assigned …

Linear carriages and the wrong rudder horns

As you might have discerned from my last post, I had no intention to go for a proper 3D-printer straightaway. More specifically: I wanted to see, what could be archieved …

More intro to bootstrapping a “Rostock” style RepRap 3D-Printer

The mechanics (I am loosely condensing my old posts under http://www.metalforum-owl.de/viewtopic.php?f=21&t=2008#p51995) are where the proliferation takes place. As everybody uses a 5-pack „NEMA 17“ stepper motors, Arduino-based control units and Hot …
