Thank you BossLaser! The FM-D Desktop Laser Marking Machine has been absolutely amazing. It's become to most used tool in the machine shop. Marking beautiful high-resolution permanent logos on aluminum is only one of many production uses. Production is now become very dependent the FM-D for so many tasks. I appreciate being able to phone and/or email BossLaser for technical support and/or sales for upgrades. I'm so lucky they are local in Sanford, FL, only a 30 mile trip from Orlando. Customers are treated professionally by BossLaser team members from reception (Elaine), sales (Steven Engen), demonstrations (Ken), tech support (Kyle). BossLaser has "had my back" since I first walked in their front door as a fiber laser newbie. I'm a happy customer.
