It became obvious that I needed to fully document the parts in my 1400x900 machine. Now hopefully I can identify bottlenecks and make the right upgrades to milk optimal performance from this heap.
1400 x 900 130 watt Chinese laser
Controller: Ruida RDC6442S-B(ec) firmware 8.01.22
Laser tube: ZS-1650 Beijing Laser Company (replacement)
Laser power supply: Light Object upgrade 100-180W
Controller power supply: Chinese 24V (stock)
X axis driver: Just Motion Control 2DM542 Micrstep Driver (stock)
Y axis driver: Just Motion Control 2DM542 Micrstep Driver (stock)
Z axis: none
X axis stepper motor: 23HD450Y-31A1 FH170713 (stock)
Y axis stepper motor: 23HD450Y-31A1 FH170713 (stock)
Limit switches: PL-05N
Mirrors: 20mm Light Object upgrade
Lens: Light Object upgrade 38.1, 50.8, 63.5mm
Obvious standout to me are the power supply and steppers. As per my usual luck, the steppers are not listed on the Smooth web page and searches turned up no data sheets. I’ll keep investigating.
The 2DN542 stepper drivers seem well-rated. I can upgrade the voltage to 36 or 48V. I don’t think they are bottleneck.
