First off I'd like to say that I am no guru myself when it comes to electronics. Swapping out the connectors is really not that difficult to do. Just take your time and read up on it and ask questions in this community. There are a lot of people that will guide you through things. I've never worked with circuit boards myself and was in the same boat as you are. I was very nervous about the fact of removing components and adding new ones. But I said to myself, "what the heck, if I mess it up, I can get new boards anyway". So I went and ordered the parts I needed and went to work. Parts are cheap too. I've replaced all of the male headers and all of the female connectors for all of the circuit boards including that 40 pin connector. It really wasn't as bad as I thought. It WAS a little tedious for me as I don't have steady hands but I took my time and went slowly until I finished everything. A couple hours here and a couple hours there each day after work and I got it finished. I must say that one of the things that helped me the most were this cheesy magnifier head strap for $4.99 from Harbor Freight Tools: https://www.harborfreight.com/magnifier-head-strap-with-lights-38896.html I may have looked foolish wearing them, but they really helped me see what I was doing. In a nutshell, I'm just trying to offer you some encouragement. Don't sell yourself short. You can do this if you put your mind to it. I have the same machine and I am working through a few different problems myself. I have parts coming tomorrow to rebuild the high voltage section of the power supply. You may not have to replace ALL of the male headers and connectors like I did but that 40 pin inter-board is a must that really needs to go. Good luck with what you decide to do. Hope this helps you decide. If you have any questions at all, ask away. I can try to help and I'm sure there are others that are more experienced than I am will chime in to help out.
