Which panels are you using to heat that large aluminum heat bed?
Would love to see some finished print results!
Thanks for sharing,
Im using 2 mk11b pannels driven at 28v.
The pannels are screwed to the back of the plate, with several sheets of high absorbency paper soaked in sunflower oil. There is a insulating mat below tgat to stop heat escaping from the back of the bed. Each heatbed is connected to its own 28v psu (24v psu with its output wound up a little), and is connected via an automotive relay, so that the printer controller is not responsable for routing the current.
Im still setting it up, but i have been getting some great prints off it. Its as slow as hell, but very accurate and stable.
The best slicer i have found for use with it is KISSlicer, i have tried slic3r and CuraEngine, but they dont give anywhere near the quality i get from kiss.
Since i took this photo, i managed to burn out a hotend, when the thermistor became detached and the board drove it up to over 300 degrees. So i have removed one of the extruders while i wait for a replacement to arrive, that seems to again have improved quality. I was supprised as to how much of a difference that made, removing the weight of the extruder and motor. So my next project will probaly be a bowden conversion to cut the weight.
I will get some shots up of the output this weekend.
