Current Status: Still under construction (It's a K40…)
Fixes implemented:
- Bad connection on the power inlet between the hot and fuse. Re-soldered.
- Jumpered water break detection since detector is NFG.
Fix needed:
- need to replace K+/K- cable. We should have a pile of the correct kind in the through-hole connector bin (hooked up to thermistors, but one can be sacrificed for this)
- Figure out proper solution to water break sensor (a: try better pump? b: replace sensor?)
Laser does work, though not yet from triggering on the front panel (or via Gcode)
Software: I suggest K40 Whisperer, as the LaserDRW thing it came with is not so hot.
Usage: It's not ready yet, so DON'T USE IT. That said, turn on the outside exhaust fan if you do eventually use it.
Safety considerations: https://techbravo.net/hosting/knowledgebase/4191/CO2-Laser-Engraver-Safety.html
Upgrades to consider in the near term:
- Dedicated Raspberry Pi w/ K40 Whisperer?
Fire Extinguisherdone- Air assist
Fume Extraction (http://www.instructables.com/id/Build-a-laser-cutter-fume-extractor/)(got one from HGR)- honeycomb base (http://www.scorchworks.com/Blog/spring-loaded-k40-laser-platform/ for a good way to do it)
Thermometer & flow meter for cooling pump (i.e. https://www.amazon.com/Thermometer-Cooling-Liquid-Cooler-System/dp/B074SDFW51/ref=sr_1_3?s=electronics&ie=UTF8&qid=1521656040&sr=8-3&keywords=LED+Thermometer+3+Way+Flow+Meter+FlowMeter+For+Water+Cooling+Liquid+Cooler+System)orderedimproved chiller pumpdone- improved exhaust fan?
- Better coolant flow detector? The one it came with is either non-functional, or our pump isn't pumping hard enough. Flow meter definitely needed
Upgrades to consider eventually?:
- improved controller board (Smoothie? DSP?)
