1st production job after lead screw upgrade. Text at 50 in/min. Laser cuts at 60 in/min through 1/8 thick balsa.
10 passes using JTech Photonics 3.8 Watt laser. Very precise cut.
Occasional vibration with rapid moves on Y with $110=$111=4000 mm/min. (may drop to 3500 and check tension on Y V-wheels).
All in all excellent result!
