LaserCAD using the network interface is a great way to communicate with your laser cutter. Unfortunately the program seems to choose the wrong interface card on my desktop and there appears to be no way to change this besides disabling all other network adapters and running the program again. https://r1ch.net/projects/forcebindip Download the Zip file install…

Laser cutter stepper motor driver upgrade
by Chester Lowrey • • 0 Comments
It was definitely time to clean up the wiring inside this laser cutter.. Something that was lashed together as quickly as possible and now has some wiring issue somewhere, best replaced with newer tech. Original double sided hand taped and etched PCBs made in 2004 for my CNC mill project – partly still working 2016

DIY gigabit POE network switch – Works with Ubiquiti 24V passive gigabit POE devices
by Chester Lowrey • • 4 Comments
I had the idea of modifying a TP-Link 8-Port Gigabit Ethernet Desktop Switch (TL-SG1008D) to be a 24V gigabit POE switch. I recently started using Ubiquiti’s gigabit WiFi gear and needed some devices to run directly off a 12V DC battery, so I could not use the provided 120V POE power injectors.  (12V to 24V provided by…
