BigBox Hemera with MGN12H Linear Rail
prusaprinters
* This is still a work in progress *The goal of this upgrade is to replace the horizontal X carriage of the BigBox with a vertical MGN12 linear rail. And to do so with the least amount of additional parts possible.You will need to buy a 400mm MGN12H linear rail and some M3x5 screws to mount the carriage to the block. I would also advise getting new GT2 belts (3m is enough).But other than this you should be able to reuse what you will take apart.You can find modified Marlin 2.0.9.3 firmware here : https://github.com/I-am-me/BigBox-TMC2130-RevoHemera-BLTouchIt is configured for my machine, with a BLTouch and TMC2130's but you can adapt it for yours.As of this version you will loose about 30mm of Y bed space. I am currently working on an improved one where this will not be the case anymore.
