Couple weeks ago tried selling my so3 but the offers I were getting were downright ridiculous so instead decided to keep it and modify to better suit my needs. There’s number of things that I like about this machine like really robust extrusions (that I was trying to find and equivalent of but could only find a t-slot ones) and very sturdy base with added aluminum bed. Things I don’t like are clearly motion system (especially the v-wheels that were rocking my hdz back and forth while cutting) and sorry to say but the controller. I just can’t get over the fact that it can work okay and few days later for no reason I’m constantly getting disconnect issues. Anyways, decided to keep the frame and install linear rails on all axis as well as bigger motors, ballscrews and use new controller (that Ive already had laying around).
I’ve seen another user make a similar conversion so I know it is possible and should be fun project to work on.
This is where the things are right now and a picture of how I aligned and tapped the extrusions for the linear rails.
