After having issue with the stock bed chipping and the cork from the heater falling off, I've decided to move to an aluminum bed. Luckily, a local company sells their cut offs for really cheap $2/lbs. As a result, I got a 1/4" MIC6 replacement piece for $8! To go along with the new aluminum bed, I've order a 200mm x 300 mm 600W silicone bed heater to run off of AC Mains. I am planning on running it through an SSR but haven't selected one yet. I am wondering if anyone has wired an SSR for the Robo and if they have recommendations/pictures? Specifically, how have people grounded the bed (or have you) due to the Robo being all plastic? Secondly, are you running a separate power cable just for the bed or running it off of the stock plug? I've discussed this with an electrical engineer but wanted to see what has worked in the Robo community.
