It's not meant to be fast or silent though you are trading those in for a much more precise control and quality in the print. Now there's still other considerations for speed and this machine will never be quiet. Also the 32bit board has much more RAM for running Marlin effectively. This means a much higher top speed without bogging the CPU down and causing issues. Now on a board with a faster CPU like a SKR 1.4 Turbo at 120MHZ can run the steppers up to 100MHZ pretty easily. This limits the step generation to about 10MHZ before the CPU gets bogged down and begins to miss steps, this is with a single stepper too, divide that across 4 and you can quickly run into issues. The CPU is what generates the pulses required to run the motor.Īs an example a RAMPS with Arduino MEGA 2560 runs at 16 MHZ. The speed a stepper can run at on a controller is proportional to the CPU speed. I forked Marlin FW on Github, the latest firmware built and setup for the 3DLS is available on my Github page Why the SKR 1.4 Turbo? With the conversion you use the A8 Y carriage so do not print the Ender3 bed carriage. #LION TWEAKS ZIP FULL#12864 RepRap Discount Full Graphic LCD case is included.400mm long 8mm 4 start lead screw with Anti-Backlash nut x 4.Your favorite extruder, I like this one.
