Hello! First post here, so not sure if this is the right category. Looking for help as well as showing off what we believe is the first high power metal cutting fiber laser powered by LightBurn.
Our company built a Carbide3D-based 1KW fiber laser that is controlled with LightBurn and uses a TF-6225 controller. We finished the build yesterday and are now trying to get it tuned.
We are really struggling to figure out a good starting recipe. It doesn’t help that the Trocen manual is pretty horrid, but I digress.
Love the LightBurn software since it can connect to the controller via USB as well as ethernet. Without LightBurn this thing would be pretty useless.
Right now we’re finding it hard to get perfect circle shapes in addition to the Z axis ‘jittering’ for the plate height tracking feature. Playing with the accel and jerk settings doesn’t seem to be helping at all.
I realize this may be the only machine of its type on this forum compared to normal Co2 lasers, but help is appreciated! Thank you!
Some machine specs:
48V at 1.7 amps to all steppers (Nema 23)
15mm wide belts on X and Y axes.
Leadscrew on Z axis.
RF height sense amplifier for plate tracking in real-time.
Calculated distance per pulse for each axis:
12.5 µM for X and Y axes (3200 pulses per rev @ 1/16th microstepping)
5 µM for Z axis. (1600 pulses per rev @ 1/8th microstepping)
