2 helpful observations

1st. Install the fuse in the upper hole, not the lower like Mark does in the video. If you install the fuse in the lower hole, the back cover will not fit because you will be ramming the back of the fuse into the PCB.

2nd. This might depend on how far forward or back you drilled your hole for the powersupply. I originally thought the back panel went on the outside of the front, but its actually the inside. In the first video when Mark tells you he likes to set his back a smidge. He doesnt say why. Well the bottom tab of the back enclosure needs to go where the power supply is. And to be honest, in Marks video he doesnt quite have his set back far enough either for the back panel to fit (You'll notice he never actually puts on the back panel in any of the videos)  My first time turning on the Extruderbot I heard a continual chirping sound. The spool turned, but in pulses in sync with the chirp. I pulled the back cover off and the chirping went away and the spool motor turned smoothly. I left the unit running and carefully put the back cover on and as soon as the bottom got close to the powersupply the unit would either chirp or power off. Well, the solution that worked for me was to take a hammer/mallet and bend the bottom tab up and flat against the back wall of the back cover, this way it doesnt get close to the power supply. Now my unit runs fine :)

Thanks...I've had the same issues.  BTW what schematic did you use?  Mr Dill's or Mr. Winter's?

To add on to the second tip, I found that there isn't a true need to drill and lock down the power supply. Looking at the position the power supply lays (after screwing the bolts and back panel, it simply doesn't ever get too close to the heater band because the screw that locks the heater band in place puts a safe distance between itself and the power supply already.

Of course does that prefer secured parts should do the necessaries, but I opted otherwise. (since I don't have a drill, or one that works anyway)

3rd. The crimp connectors that were supplied with the kit are very large compared to the provided wires. I found the wires slipping off the connectors even after crimping them. I don't know if anybody else has done it like this or it's common knowledge, but this is what worked for me.

Sorry for the slow response, I ended up not using either schematic, I just ended up pausing and rewinding the youtube videos A LOT and verifying I had my wires in the same positions as the videos. I would reccomend using Mr Winters schematic though, as Mr Dill didnt bother to verify his own schematic, or offer it as a download.
