    The baud rate is definitely 9600. I always connect to the Navigator firmware with no handshake. Try turning off XON/XOFF and if you still don't get a response, try swapping pins 2 and 3. I have always had good luck with PuTTY. It's free. Another super basic test is to loop pins 2 to 3 and make...

    Hello, I am trying to establish serial communication with no success. Serial port is 8-N-1 Xon/Xoff, varied baud rate from 1200 to 9600, checked serial cable, it is straight through (2-2, 3-3, 5-5). Tried commands ?V and ?WARMUP% with CR at the end. Tried two different terminal programs Termite and...

    ... as lasers will add a bunch of other (partially unresolvable) problems, my best bet will go back to ceramic blades in a rotating head and/or upped with ultrasonic energy :cool: Viktor

    You're on point. Dust is a real problem. But it's a problem even without lasers involved and a regular maintenance is a necessity. The hope here is that correcting a laser is easier than a metal blade. Sometimes, packages are reinforced with metal braces like this: A metal blade...

    One other consideration here is that you will need to deal with combustion/ablation products from laser cutting. The material that is removed during laser cutting doesn't just "go away", it's converted into other substances including smoke and soot and other particulates and volatiles that like to...

    Wiring them as you describe will likely fry the drivers, at the very least the negative voltage regulator will be toast. Wire them in series as buffo describes.

    This is weird. I put "Grainger Performing Arts Center" into Google Maps, and it took me to "Kinston Lenoir Performing Arts Center" (2601 N Queen St, Kinston, NC), which is another PAC in Kinston, but it's right next to a high school (Kinston High School) with all the amenities we're looking for. ...

    Not quite. If you do this, both positive terminals will be +24 volts. What you need is a +24 volt supply and a -24 volt supply. Instead, you want to connect the positive terminal of one PSU to the negative terminal of the other PSU. This common connection point will be your new DC ground. ...

    I just got a set of new DT50B. It arriwed with 2 pcs of 24V DC PSU`s insted of 1 pcs that i have for all other scannersets. The PSU`s don`t have the normal +/common/- wireing but just plain positive and negative terminals. So in my mind, I can wire this up hooking up both PSU`s with the nevative...

    To the main topic: I just bought some cheap 352nm torchlight and will be testing if scotch tape is transparent at this wavelength. If it's fully transparent at 352nm, my only remaining option would be galvo CO2. If it's absorbing a reasonable amount, I will consider buying a galvo 352nm...

    Looks terrific! galvo + CNC is a great combo. Recently, an even better one has become somewhat affordable: laser + 6 degrees-of-freedom robot arm. That allows to go beyond x/y/z and beyond flat objects, but more heavy on software. galvo + XArm6 is the route I am currently seriously...

    Got it, thanks! These 445nm diode modules are amazing. Yeah. In my case, there are three primary materials: - corrugated carton; light brown. I kind of able to get through it with my fiber laser, but it mostly burns than ablates. - thermal shipping labels. Bright white. It's extremely hard...

The fiberlasers were at 1064nm and cuts coloured/dark paper or adhesives without problems, but could be problematic with white or transparent materials. For samples/images -- read through this thread...

    The fiber laser itself is fine; I have no problems engraving steel / aluminum / brass. As for parameters, it's certainly possible that I just failed to find the right combination of frequency / power / speed. If anyone has a hint, I will very much appreciate it.

    I like it! The term definitely fits! My next post I'll have a short video of my dimple glass. Ions are still king when it comes to uniform divergence, beam quality, and of course, there is no mucking about trying to get your beams lined up to get a good white. Also, the range of wavelengths...

    IF THAT IS aLL your fiberlaser did at 20 watts, it sounds like it was not programmed correctly, set up properly, damaged, or driven with the wrong signal. Was there an F1 lens in front of the fiber to focus the light? STEVE

    I took a look at the satellite view of Grainger Performing Arts Center in Kinston, NC and see a couple pros and one major con. Pros include a community center and gymnasium right next door. There is also a small park behind the PAC that might be suitable for droning activities. The con is that...

    Hi Viktor, Speaking about the 20W pulsed fiber laser: which wavelength? I did try using 1065nm 20W Q-switched fiberlaser to no availability. It would not cut tape or paper at all. At best, I could burn paper (very slowly). Same question about laser diodes: which wavelength? Also, if you...

    That would be amazing! Thank you in advance. Unfortunately, the boxes are from multiple third-party vendors (mostly from China). There's a zero chance we can influence them to change the box design.
