I’m hoping someone with the right experience could weigh in with comments about some visual bands while Bi-directional vector engraving. 2.5% Overscan, 0.1mm Interval. Cross-grain on 3mm birch ply.
It looks like the laser isn’t at full desired power on occasional scans, and primarily on right-to-left scans and then resumes to full strength. These marks appear randomly and not consistent when engraving the same file again.
Reci T1 (75W) and Cloudray MYJG-100W power (rated 80-100W)
I’m using LightBurn and the LaserBoard, onboard drivers, with the following config if it matters:
alpha_step_pin 2.0 # Pin for alpha stepper step signal
alpha_dir_pin 0.5 # Pin for alpha stepper direction
alpha_en_pin 0.4 # Pin for alpha enable pin
alpha_current 0.4 # X stepper motor current
alpha_max_rate 24000.0 # mm/min
alpha_acceleration 2000 # mm/sec²
beta_step_pin 2.1 # Pin for beta stepper step signal
beta_dir_pin 0.11 # Pin for beta stepper direction
beta_en_pin 0.10 # Pin for beta enable
beta_current 0.6 # Y stepper motor current
beta_max_rate 24000.0 # mm/min
beta_acceleration 2000 # mm/sec²
Please let me know if I’m missing anything useful.
Thanks in advance for anyone who recognizes this, and could offer some advice.
