MakerBot Percussion

Calling all cars, I need some help! I\'ve uploaded the housing for a solonoid, (link). If it works, we\'ll have a really awesome solenoid drumbeat to control through gcode to compliment your Makerbot music. The goal is to make it so that as your playing music on your machine with the steppers, a solenoid can hammer out the beats. I\'ve been having fun working on it, but I\'ve hit a wall.

Here\'s where I\'m at:


The maximum number of voices a Makerbot can produce is three (x, y, and z axis). Harmonies can be made with these three step motors, yet the tempo and pitch of the motors are not always consistent. My initial idea was to build an external percussion instrument with a solenoid, which would perform along with Makerbot step motors. The extruder module includes: OWM driver board, DC motor driver board, temperature sensor board, RS 485 comms and arduino.



Pressure valve control can be toggled on the control panel or called with the M command (M126/ M127). I chose the
