Standing on the shoulders of giants, there will be more possibilities in the 3D printing world.
.
This solution uses the high performance of RPi to drive the printer motor directly. It has more potential, e.g integrate the software octopi, add the big lcd to display 3D view later.
.
What makes it special?
.
3d printer firmware run on raspberryPi and control printer directly. for increasing print speed and smooth. control 3D printer directly,except the temperature control which is just to maintain the temperature. 1)the GPIO being able to signal at 10+ Mhz for the 2B+ as compared to 8/32bit MCU limit of about 10Khz/200khz for steps. Test results: 3.5Mhz GPIO test on RPi3+ 750Khz run marlin on RPi3+ 2)Real Time linux kernel 3)opensource. 4)it can work with Octoprint in one raspberryPi. package list: 1 PandaPi shield board […]
