- Class IV
- 60x90 cm bed
- 90W CO2 Laser (dont run above ~70%)
- ~10l of destilled water
- CW-3000 water chiller
( updated 2019/01/20 by jglauche )
- fix outlet ground wire issue
- fix cable management
- get the water out
- replace laser tube
- find a better spot for the water cooler
- rinse the whole system with a couple more liters of fresh water and discard the output to flush the rest of the crap out of the system
- get a beam combiner for adjustment
- level Z axis
- find a way to get exhaust fumes out
- new 90W 80mm diameter laser tube
- Hose for the exhaust (longer)
- beam combiner
- can only take 80mm tubes, for different diameter, the plastic mounts have to be replaced/modded
- laser tube length is limited to 120cm to fit the frame.
- Couldn't verify the electrical connection on the cathode.
- there's a 80W power supply for tubes in there and a 90W tube.
- the power plugs on the machine are NOT safe to use unless used with an erect male ground pin plug. Also the middle one misses its ground pin connection. A plan would be to install European sockets and add some smartness. For example, let the water pump run for 5 minutes prior to startup to make sure there is no air bubble left.
- We should move the location of the laser power supply. It's too close to the water inlet and outlet; if any of those fail in operation it will pour water directly on top of it
suspected Exhaust fumes extraction problem
- Remove window above hallway door, replace with wood. mount pipe onto wood.
- Cut hole in door, fit pipe over hole in door
- Cut hole in air duct, mount pipe over hole
- Decide on coarse filter, as the supplied filter will clog if use without.
- Open door and toss out hose when in use. Revert when done.
suspected Electrical problems
Hook up groundThe machine's ground is wired internally to the euro socket, so no need for external ground.
- Unless there is no ground on the socket so when connecting the ground must be checked.
10/4 Laser cutter does not give output power anymore after first successful test run. no high frequent buzzing anymore one should expect. Only what appears the sounds of sparks on first fire. then nothing.
16/4 Opened up laser power supply (I know what I am doing) (famous last words) and it appears the flyback transformer is toast. the secondary of the transformer measures fully open. (or the resistance is >30 M Ohm)
Also the power supply appears to be a 80 W model whereas we have a 90W tube. Thoughts ?
- get new power supply. about €200 ish
- get new flyback transformers and just hope it works. This is the cheaper option.
Power rating is 90W. Tube length is 120 cm.
- chaos chaotically ordered a PSU on 2016/04/27(or around) to replace the broken one ; http://www.aliexpress.com/snapshot/7615321008.html?orderId=74879451300975
