So my question is, would there be any interest in a board like this? There are things still to test and improve in the HAL, but I have contributed all the code to the Marlin 2.0 bugfix branch, so anyone can test, contribute, or use it as they wish, so there is no barrier to add support for more commercial boards.Ĭurrently producing this board in quanties the price may be around $60-80 depending on the final options.

I am using the excellent ESP3D code in an ESP01 to use as a wifi bridge, and printing remotely with Repetier host, and both that and printing from the local SDcard work great. I have been using this board now for a couple of weeks to 3D print and laser engrave, and I'm really happy with it. 6 end stops, including support for BLTouch.

4 high port Mosfets for hotends or anything else.

Other options I have considered, and have planned pins for them, but not built in my current version of this board are:

Multiple pins in expansion connectors, including hardware SPI and Serial ports.

LCD and SDCard connectors for standard displays.1 Hardware SPI port available in LCD connector and a separate hardware SPI port in SDCard connector.

64Kbit eeprom on board to save settings, bed level mesh points, etc.

1 PWM controled fan, 2 more 12V outputs for fans or anything else.Separate heatbed in and out, up to 24V.4 endstops inputs (can be used an output too, and pins available for more endstops if needed).6 Pololu format stepper drivers, pins for up to 8, could add a expansion board, or a second version of the board with 8 steppers.Could use STM32F103VET with 512KB of flash and 64KB of RAM, or STM32F407VET with 512KB of Flash and 192KB of RAM. STM32F103VCT, with 256KB flash, 48KB of RAM.Several options: STM32F1 Cortex M3 at 72Mhz, or STM32F4 Cortex M4 at 168Mhz The board has been designed from the ground up for Marlin. May be able to run stm port of smoothiware, but have not tried it in any way. These are the current features of this board: In the last couple of months, I decided to write a HAL for Marlin 2.0 to run in STMF1/F4 boards, using the libmaple based stm32duino core.ĭuring that process I started designing my own printer board to fit my needs, and I am wondering if there is any need from other people for a board like this, in which case I'd try to do a kickstarter to get volume production and volume pricing. This is my first post here, but I have read many threads and found great advices and comments, so I am posting here to get opinions.
