Some days ago I spent some time with my friends from Hackerspace Frankfurt and Protoworx. They helped me to do some machining needed for my UP3D Super-WIFI project: Here is the story: First some cutting to the existing housing of the router. Then making a lens from acrylic glass. Left: new lens and changed housing. Middle: I2C […]

UPDATE !!! IT’S WORKING !!! scroll down for more info 🙂 A friend of mine got a replacement of his UP! mini CPU board recently and when opening the machine after repair a new CPU board with quite some interesting features showed up: You clearly can see some unpopulated ICs on the left and the […]

Due to the demand I wrote a small how to for the UP3DTOOLS You can find small notes also on my github directly: https://github.com/MaikStohn/UP3D A nice GUI application is in the works, but this will take some time. The tools now can be used like this: 1.) slice your object and save the myobject.gcode file to […]

I found a set of nozzles on ebay. They been supposed to fit on up mini / makerbot style hotends but… … the UP mini nozzle (on the right) had a much bigger hole (3.5mm) inside since my UP mini has a metal pipe which inserts in the nozzle (good solution to avoid friction caused […]

Printing first object transcoded with G-Code transcoder: Simplify3D, 0.1mm layer Acceleration 3000mm/s^2 and travel moves with >300mm/sec caused some missed steps. That’s why this little friend is looking a bit strange. Reduced the settings and next print came out a lot better: UP G-Code-Transcoder full source code (and now also pre compiled binaries) available […]

Today I made the first test prints. 20mm calibration cube, sliced with Simplify 3D: 0.2 layer height, no infill, 2 perimeter, raft The 1st print (left) had a much to big extrusion multiplier, which I changed for 2nd print (middle) to a much too small value. The 3rd print (right) almost had a good value […]

Finally I managed to decipher the last machine command (CMD4) and was able to build a encoder for it. In the video below you can see my UP! mini running at insane speeds (700mm/s). In the video: Move 100 mm in x and y at 200,250,300,…,700 mm/s, then a test sequence I use to track […]

In the video you can see Marlin running 1/64 microstep @ 13000 / 16000 mm/min feed rate, using HTD3 with 12 tooth pulley –> apx 77khz / 94 khz –> quad stepped 19khz / 23 khz timer freq. The first part (before Y move as a delay ;-)) uses same positions and speed like the […]

USB repair of my A1278 (MacBook Pro 13 – 2012)
Since Apple decided not to manufacture a new usable MacBook Pro (Minimum: Core i7, 16GB RAM, 2 TB SSD) I have to continue to use my old MacBook Pro 13″ from 2012 (Core i7, 16GB RAM, 2x 1TB SSD). Unfortunately due to some mistake I connected reverse voltage on one of the integrated USB3.0 ports. […]
