My printer doesn't have a heated bed, but I want to build one myself. I have found some great tutorials for that so that must be possible. But I want to turn it on and off automatically when starting a printjob, so I was wondering if I can use Octoprint for that. I don't use Octoprint now so I totally new into this, but before buying the needed hardware I will try to find the answer to this.
So can I connect a custom build bed through USB and can Octoprint control it? Are there some thing I need to know before doing this? Or are there some ready to use heated beds which will work out of the box with octoprint?
My printer is a Rotrics DexArm (from Kickstarter) which is more than a 3D printer, but when I change the module then I will manually disconnect octoprint and the bed, so there is no need to think about that.
