Alpha Support for E3D

thingiverse

This is a customized support designed to fit E3D V6 Hot End for the Hatchbox Alpha perfectly. You will need four 5-40 Socket head Machine Cap Screw 1-1/4", and nuts, which connect the support both to the delta arm and to the hot end with two screws each. The Hatchbox Alpha firmware is included, which needs to be compiled and uploaded using Arduino IDE 1.6.5 only (later versions won't work). In the firmware, you will find the file configuration.h where you have to search for (#define EXT0_TEMPSENSOR_TYPE) and change its value to 8, as this is the correct setting for the E3D V6 Hot end. The E3D thermistor worked better when switched from Repetier's temp controller Deadtime (which was on by default on the Alpha LCD) to PID controller in the configuration menu. You will need to perform an extruder PID tuning using command M303 E0 P180 C3 in your slicer, then take the average of each iteration and add the values of kp, ki and kd to the P, I and D value for the controller, leaving Max and Min at 230 and 40.
