Why does it matter if the printer shakes around. Just so the print surface is in sync with the extruder. Movement from printer to floor only matters if it is shaking your house or something next to it that needs to be still. If you are setting diamonds or painting pin heads on the same table as printer --- the movement induced to the table by printer is a problem. Should you be concerned andby cozmicray - Developers
Keep this printer to print parts. Build up another printer to meet all your requirements / desires Sounds like you want MAJOR update! You can get all the parts on eBay or other outlets. Gears?

I would review your test procedure for a diode driver this is pulsed DC to diode and ammeter may not show current and can you measure this pulse --- perhaps a O-scope Why does uncle_ding call this a 15W laser when spec says Model Number: LJ450nm1.6w Output power: ≥1200MW Operating mode: tunable Motivation method: electric incentive Working substance: Semiconductor I would ask "uncle-ding" foby cozmicray - Laser Cutter Working Group

Outstanding thread Bravo on New RAMPS ?? Where does the arduino plug in ?? MOSFET Why not MOSFET with large tab off the PCB, that can be thermally synced with radiator?
