Machine: OMTech K40 (blue box)
Firmware: Smoothie (I assume, I didn’t change the LaserBoard firmware)
Hey all! I got the LaserBoard for Christmas (you rock MIL!) and I am having some trouble these days with the Y Axis. I am not sure this is related to the LaserBoard but it only started happening after installation.
Lately I have been getting some occasional hitches in my Y axis movement and even more recently it has turned into every job it hitches in some form. Quite annoying.
I read the “How to tune your laserboard” article and tweaked the following values in hopes that it would do something in the way of slow the movement down and give it more power. It hasn’t seemed to help much or at all:
beta_current: 0.6 -> 1.0 # Y stepper motor current beta_acceleration: 2500 -> 300 # mm/sec²
I recently replaced my Y axis stepper as well (with like kind, OMTech actually send me one) and the issue persists.
Any hunches or help would be greatly appreciated. I was in the middle of making party favors for my wedding this July so I’d love to get this fixed. If not I’ll be upgrading to a larger laser sooner than expected.
