GRBLDuino Mega Shield V1 Assembly Guide

Here is the step-by-step process to assembling your GRBLDuino Mega Shield V1.

First, lay out all of the parts and group them together.

Place the Arduino header pins into the PCB from the bottom side. Only these 7 headers will be soldered on the top side of the PCB.

Insert all of the remaining header pins into the correct locations on the top side of the PCB. These will be soldered on the bottom side of the PCB.

Next, insert all of the components. Bend the leads to hold them in place (the large capacitors will likely stay in place without being bent).

Pay attention to the orientation of the resistor network (the single line, 6 pin, yellow or black package). The dot on the one end gets aligned with the box printed on the PCB.

Finally, Insert the stepper driver sockets, making sure they are sitting straight.

Finally, some Arduino Mega variants have a USB A connector with a large metal housing. This housing interferes with the X axis driver socket pins. I trim the pins nearly flush, touch them with the soldering iron to round them off, then insulate them with UV cure solder mask.
