I have two minor problems. Please help with the solution
I have two minor problems. Please help with the solution.
1,If I first switch on the main switch on to K40 and then plug in the USB cable to PC, I will not find the display. If I do this in reverse, everything is fine.
2, Instead of the A4988 Stepper Motor Driver I used the Drv8825 Stepper Motor Driver. All images after burning are half-sized. Can I set a different number of steps in the config file? Or is HW intervention necessary? So far I have only changed it through the display. For the time being, I’ve modified it in config:
alpha_steps_per_mm 315,15 # Steps per mm for alpha stepper
beta_steps_per_mm 315,15 # Steps per mm for beta stepper
gamma_steps_per_mm
Everything else works as well, and thanks for such an excellent control board.

The drv8825 will default to 32microsteps on the c3d board. You will need to double the steps_per_mm in the config.txt. 315.15 would be correct.
I turn on the computer first before the laser. The display usually initialize correctly that way.
