RedShift Laser Parameter Tuning Checklist

Pre-Cut Inspection

• [ ] Lens is clean and free of debris
• [ ] Mirrors are aligned properly
• [ ] Focus is set correctly for material thickness
• [ ] Assist gas pressure is verified
• [ ] Nozzle is clean and undamaged
• [ ] Material is flat and secured
• [ ] Exhaust ventilation is on

Test Cut Procedure

• [ ] Use scrap material from same batch
• [ ] Start with "Optimal" speed (not "Max")
• [ ] Cut simple test shapes:
  • [ ] 50mm straight line
  • [ ] 20mm square
  • [ ] 20mm diameter circle
• [ ] Inspect results for:
  • [ ] Complete cut-through
  • [ ] Edge quality (smoothness, no charring)
  • [ ] Kerf width consistency
  • [ ] Dross on bottom

Parameter Adjustment

If cut doesn't go through:

• [ ] Reduce speed by 10%
• [ ] Re-test
• [ ] If still not through, reduce another 10% or increase power 5%

If cut is burned or too wide:

• [ ] Increase speed by 10%
• [ ] OR reduce power by 5%
• [ ] Re-test

Important: Only change ONE parameter at a time!

Results Recording

Record in your parameter library:

• [ ] Material type and supplier
• [ ] Thickness (measured)
• [ ] Power setting (%)
• [ ] Speed (mm/s)
• [ ] Focus position
• [ ] Gas type and pressure
• [ ] Result rating (1-5)
• [ ] Notes/observations
• [ ] Date tested

Troubleshooting Quick Reference

Problem	Likely Cause	Solution
Top cuts, bottom doesn't	Focus too high	Lower focus to mid-thickness
Burning/charring	Too much power / too slow	Reduce power or increase speed
Incomplete cut	Not enough power / too fast	Increase power or reduce speed
Tapered kerf	Focus wrong	Adjust focus position
Dross on bottom	Insufficient gas flow	Increase assist gas pressure
