My3dP: printing…
After some months since my last blog post about my 3d printer, here’s a couple of shots during the printing of the classic hollow calibration cube…
My3dP: first movements!
This weekend I spent some time to complete the setup of my 3d printer. First I replaced the extruder – I broke it during the assembly – with a new one from MakerFarm: After the fine positioning of the endstop microswitches, I could make the printer move!
My3dP: a little mistake…
Today I noticed I made a little mistake during the building of my 3d printer: the plastic holders for the rods of the y axis were mounted rotated 180 degrees and therefore the printing plate was too low: The proper installation is as follows: Now the endstop for the y axis also works fine:
My3dP: power supply
I chose, as power supply for my 3d printer, a common ATX power supply for desktop PCs. The Printrboard has a connector for the power supply’s 12V plug: To turn the power supply on, you need to connect the green wire (PS ON) to a black one (ground). I therefore opened the power supply, cut the…
My3dP: the electronics
The kit I brought from MakerFarm includes the Printrboard as electronic to control your 3d printer: This board, developed for the Printrbot project, has the following features: Atmel AT90USB1286 microcontroller (can run the most famous firmwares like Marlin or Sprinter and manages the USB communication to the PC); 4 Allegro A4982 stepper drivers (3 axes + the extruder); MOSFET outputs for extruder, heatbed and an optional fan;…
My3dP: the extruder
I’ve just completed the assembly of the extruder for my 3dprinter… MakerFarm’s kit includes the one designed by Greg Frost: at the bottom of the extruder you have to connect the hotend; I’ve already blogged about it in a previous post: extruder and hotend are then mounted on the x-carriage:
My3dP: hotend
Here’s the hotend for my 3d printer, a J-Head Mk IV-B that MakerFarm sells pre-mounted: I had only to wire and insert the resistor and the thermistor:
My3dP: body completed
Last night I completed the body of my Prusa: Here are some photos about the three axis:
My3dP: main frame completed
I completed the building of the main frame for my Reprap Prusa: Unfortunately the z-stabilizers had too small holes for the nuts: when I tried to put them in the right place, I stuck them. Colin, MakerFarm’s owner, has graciously offered to send me two new stabilizers!
My3dP: frame triangles
I’ve just finished building the two equilateral triangles (29cm wide) that create the main frame of the 3d printer:
