A quick run through of a few mods to my latest toy. Inductive auto bed-levelling (£9 Ebay) or Z axis endstop mod (free), Skynet V2 Firmware (free), improved filament cooling fin (free), psu cooler (free - old pc fan), motherboard cooler (same) and spool hub with bearings (a few quid off EBay). Links to useful vids on setup and reviews below:

Please note. If you are using Skynet V2 (as linked) thn the Z offset should be adjusted on the printer's LCD screen per instructions in the download link. If you are using v1.1 then it is done in Arduino as per the linked video. I hadn't fully figured it out when I made the video :) Good luck all.
