Machine: Blue laser, 6 year old machine 900x600 - Cohesion3d
Firmware: “I have a new board and I’m using whatever it came with”
Problem/ Question: Hi all. I am upgrading the ancient controller which i have no control software to run it. I have been able to nut out everything to get the machine to go the right directions, home the correct way etc. But i cannot get the steppers to calibrate correctly.
I am running external stepper drivers on the X and Y. Currently the steps per are
alpha_steps_per_mm 157.575 # Steps per mm for alpha stepper
beta_steps_per_mm 157.575 # Steps per mm for beta stepper
gamma_steps_per_mm 157.575 # Steps per mm for gamma stepper
So I test using Lightburn and the go to function. I tell the machine to got to 100mm from the home position. It only goes 55.5mm. I calculate the correct steps per and it should be 283.9189.
I replace the value using notepad and save it. Remove the SD from the computer, plug it back into the LaserBoard and power it up. When i test it again, the steppers make a hell of a noise, and it only goes 27mm. Regardless of what i do, the machine only works smoothly and nicely at 157.575 steps per, and only goes 55.5mm.
Anyone have any idea on what I can do to get the machine to calibrate? Also, have i missed something??
