Going to be building a bit of a Frankenstein Printrbot Play in the coming weeks. Already placed orders for a Matrix Precision EX-105 upgrade, Gearhead V2, Ubis 13S, 4 start lead screw and Azteeg X5 Mini with SD6128 drivers.
My goal is to maintain the robust and portable nature of the play while also having a large enough build volume to print functional parts. I’m very interested in comparing the performance of the Ubis 13S side by side with the E3D V6.
One area I am currently struggling with is the heat bed (and power supply). Normally I would opt for the 203W/16.5A Xbox 360 power supply because they are cheap and relatively compact, but the silicone heat bed I have my eye on is more demanding than the MK2 PCB heatbed I’ve used in the past and well beyond what those power supplies are capable of.
This has led me to look into using a 120V AC silicone heater in combination with a solid state relay. While obviously this requires significantly more care to be done safely, I think it may be the best solution to have an all-in-one printer that doesn’t require me to lug around an ATX size power supply with it.
Looking forward to any feedback/thoughts on this approach.
