Been working hard. Most of the modification is done. Cabling is nearly done. All I need is to put new 12v pump, flow meter, water level sensor and finish programming Arduino which takes care of reading, displaying and reacting for events.

K40 Laser Update 2
Slowly, but we are moving forward. Air assist with selenoid valve (madness!) and flow adjuster. Air provided from airbrush compressor via 1/8 BSP coupling. Cable/pipe chain, stepper cable holder – small things but still improvements. Testing 3″ 12V bilge fan with PWM motor regulator – on full power it sucks like… never mind, and is also a bit noisy. Half speed is enough to suck out any smoke from plywood cutting. 3D printed smoke manifold. Things left to do: cooling sensors cluster, switching panel.
