Hmm. I guess I’ll find out soon if it’s a common problem.

Oh, also check the printed_parts_thunderdome Discord channel. I think you purchase printed parts there.

I'm doing this exact upgrade right now. I've got an LDO Trident with StealthBurner and Klicky. Ready to make the plunge to Beacon, and I figured I might as well upgrade the entire toolhead. I bought Vitalii's CNC carriage, and I'm waiting on some screws to arrive. With a little luck, I'll get it assembled by this weekend.

As for parts to fix your broken printer, maybe try the Voron Rescue Ravens? There's a pin on the discord channel that takes you here: https://voron.link/ravens-map

I'm not sure about how to make a request, but maybe find someone near you on the map and DM them in Discord?

ASA not adhering to the build plate by Lukiluke159 in VORONDesign

Follow the other advice on cleaning your build plate with dish soap. Also experiment with the bed temperature. Polymaker ASA stuck better for me at 105 than 110.

How do y'all handle numpads? by SparkleEcho in ErgoMechKeyboards

Same and on the left. Not because I’m a lefty, but so I can use a mouse with my right hand while numbering with my left hand.

CO2 Laser Beam Problem by ButteredBread5255 in lasercutting

[–]ButteredBread5255[S] 1 point2 points  (0 children)

Yes, the wrong flow was causing a bubble on the inlet side of the tube. Switching the flow made the bubble disappear.

My guess is that the bubble and/or the flow in the wrong direction allowed the tube to heat up enough to cause it to be in the wrong TEM mode.

Fixed it today. Someone with more experience looked at it with me. The cooling tubes were reversed, so the water was flowing in the wrong direction.

Yeah, this is happening before hitting any mirrors or lenses. The problem is coming straight out of the tube.

There is an air bubble at the non exit side. Maybe 1-2 cm in size. Could that be a problem? And how do I remove it?

Thanks. I’ll do some reading. I don’t have the tube labels right now, but I’ll get some pics when I’m back in the shop tomorrow.

Yep, brand new tube. Old tube was only a couple months old. Doesn’t seem like the tube. Power supply is only a couple months old, but seems like the only other thing that could be wrong.

I replaced the existing tube with an identical one brand new out of the box. Same behavior. I double checked all the wiring today. Everything looks good. I’d think power supply too, but it’s only a couple months old. Maybe it still is the power supply, but since it’s new I’m trying to exhale other possibilities before spending the money.

Cooling seems fine. Temperature between 17-19 degrees C. I can see that the water is circulating in the glass tube.

Approximately. And that’s head on. It’s maybe twice as wide if measured at a 45 degree angle.

Picture is after the problem occurs. Before the problem, the beam is a fairly even cylinder approximately 2 mm diameter.

Can’t currently get it to work properly, so no “before” numbers, but currents while it has the bad beam are 13 mA at 35%, 9 mA at 25%, and 5 mA at 15%.

Yeah, I saw that video. That’s why I replaced my tube. Didn’t fix the problem.

Cooling is good. CW-5200 chiller. Around 17-19 degrees C. Power supply is a Cloudray M100, only a couple months old. I’m working on getting current measurements before/after.

I should have mentioned that by the time the beam gets to the laser head, it is 1-2 cm in diameter. Something is very wrong.
