Home Made 3D Printer

Hi All,

I wanted to 3d print this 2014 pulse motor build off, but I still have to calibrate it.

This is my 3D printer:

Tommey it looks like you are pretty close. 

One comment:  I would think that you would want something flat and dimensionally stable like a sheet of glass for the platen.

BTW what did you end up using for your step motor driver boards?  Those amazingly cheap Chinese Allegro A4988 based boards are really only good to about 1A.  I like the A3979 which can really and truly handle 2A, but a clean PCB layout really requires 4 layers.

Hi Mark,

I'm using at90usb1286 board, it was a pain to load but it's a good board.


My 3d printer is fast, but have problem when printing and the extruder goes very slow when running code.

When in control mode, its as fast as it can melt the plastic....

Tommey, I was asking about the motor drivers themselves, the devices that actually connect to the motor, not the microcontroller.

The problem with the extruder is probably a bug in the code.  If you send me what you are using I might be able to offer some suggestions.

Hi All,

Did a little calibration on marlin software, I think this is not bad at all.

My heat was a little too high, but it's alive
