![]() ![]() You can download our dev image from the user name, and the make scripts pretty much automate everything except a marlin boards configuration. Most of our stuff is made by volunteers for other club members… We support each other, respect the efforts involved, and encourage measurable improvements. ![]() We are also of the opinion that solving our own needs was more important than trying to satisfy the unrealistic expectations some users have for low-volume club electronics. It really is a shame, as we all liked how well the RAMPS boards were so well documented. The cloners simply fragmented several other open-projects with incompatible motives from irrational commercial interests, and content-publishers tended to to get their “hate on” before submitting a bug report. However, I do understand about the Alpha/Beta design doc withholding though… while we do regularly publish our software config back to the community… we also now keep Beta schematic/pcb info within the legitimate core developer/users/parent-project/contributor community after seeing the hazards off-version RAMPS v1.4 clones became. This is mostly due to everyone already extensively documenting the 2560, and parts should be easily replaceable 5 years from now. We build something less creative, as we wanted to preserve the existing Arduino use. I like that people are exploring alternate designs like this 32bit rig… The board has an automatic cooling fan to help keep itself cool, and with an XT60 connector for power, it should even be relatively easy to take your printer on the go with suitably beefy RC batteries. The board is powered by a 72 MHz STM32F103 chip, and uses state-of-the-art Trinamic TMC2208 stepper drivers to achieve near silent operation. Marlin powers the majority of 8-bit desktop 3D printers (even if their owners don’t necessarily realize it) so sticking with it means that users shouldn’t have to change their software configuration or workflow just because they’ve upgraded their controller. Being small and cheap is already a pretty big deal, but perhaps equally importantly, his board is running the open source Marlin firmware. With this board, is hoping to create a simpler upgrade path for 8-bit printer owners. It should also go without saying that they aren’t cheap. Of course, there are already a few 32-bit control boards available on the market, but these are almost exclusively high-end boards which can be tricky to retrofit into an older machine. Surely we can do a bit better than that in 2019?įor his entry into this year’s Hackaday Prize, is working on a 32-bit drop-in replacement board which would allow 3D printer owners to easily upgrade the “brain” of their machines. In fact, the common RAMPS controller is essentially just a motor driver shield for the Arduino Mega. It might not be the kind of thing you’ve given much thought to, but if you’ve ever used a desktop 3D printer, it was almost certainly being controlled by an 8-bit CPU. ![]()
