Back up for sale as buyer was not willing to continue repairing/adding to it due to my error, and was thus returned and refunded. A new trigger and board have been fitted which got it working, but it seems the eyes is the last remaining problem, so could do with replacing, aswell as a new macroline. I will be confirming with the previous buyer just in case he encountered anything else, but do take note there are some small things that need fixing, hence the very low revised price of the gun. All information is in the original post.
