Electronics Robot arm 3D-printing
thingiverse
I need four stepper motors for the robot arm, one each for X, Y, Z arms and extruder, plus a fifth motor to rotate tubes. My existing electronics only have space for four stepper motor connections. To overcome this limitation, I've upgraded to an Arduino Mega 2560 R3 control board and a Ramps 1.4 board. I've also added a 2004 LCD display and five A4988 drivers. The power supply unit is a Techsolo Micro ATX 12V-400W. To house the electronics, I've modified a box found on Thingiverse (http://www.thingiverse.com/thing:1437311). For printing the robot arm itself, I used the model from http://www.thingiverse.com/thing:1725519. Here is the link to another related project: https://www.thingiverse.com/thing:3846234.
