I have a CBeam XL and I'm getting missed steps on my Y axis, which is dual motor. I use a TinyG and have it dialed in, but I tried to up the velocity, feed rate, and jerk and it caused the missed steps. Would that be too low current? I have room to increase it and try again, just want the machine to move faster. A few suggested binding as an issue...
What speeds does anyone else get from theirs? I don't know what the motors are capable of, and this was nearly no load - I was running a drag bit.
CBeam XL and speeds
From the original Synthetos forum (2011–2025)
Hard to tell from YouTube, Is machine screw or belt?
Do you have a heavy spindle?
Too much jerk or too much velocity can result in missed steps.
Turn Pots all the way up, then slowly reduce jerk until it stops skipping., may work.
NEMA 23s?
