    TIG Brazing a copper boiler?

    Nevermind, I found the answer in "The Home Machinist". In a nutshell, the answer is NOPE, it won't work.

    You said that was a spray used with a laser? Did the laser actually etch the metal because of the spray, or did the spray get vaporized and bonded on the surface of the metal? Either way it looks pretty good in the picture. Don

    TIG Brazing a copper boiler?

    Just sitting here thinking, which can be a dangerous activity at times... Would TIG brazing a copper boiler using silicon bronze rod be a viable method of assembling the boiler? Has anybody tried it? If so what were the results? Just wondering. Don

    Use a non-contact infrared thermomator as a pyrometer?

    If a video shows up on YouTube of somebody putting blue painter's tape on top of molten aluminum to get a Harbor Freight IR thermometer to register the temperature, remember it wasn't MY idea, it was Andy's. I'm not taking the rap for this one! You guys will back me up on that right? Don

    Use a non-contact infrared thermomator as a pyrometer?

    I can guarantee that the Harbor Freight IR thermometer won't work. They don't like reflective surfaces. Mine won't even give me a reading off my aluminum hot block or the aluminum print bed on my 3D printer. If I put a piece of blue painters tape on the print bed or the hot block, I can take...

    Filament Splicer

    Andy: When I was using Slic3r for my slicing software I hated their supports, both the original Slic3r and the Prusa Slic3r. It always put a platform on top of the support columns, and that was a royal PITA to clean up. So I also avoided supports like the plague. Then I went to Simplify3D...

    CNC controller

    Ray: Good luck, and I hope you still have your hair by the time you get it built. The TB6600 controllers, I've heard some good things and some bad things about them. How are they working out for you? I'd read that they were marginal for a Nema 23 motor at 3A, so I went with the DM542's that...

    CNC controller

    Unfortunately, due to the tremor in my hands, soldering up a kit is no longer an option. Crimping a terminal on a small wire can be a challenge too, but I'm building work-arounds. I'm still waffling between ball screws and belts. How big of ball screws did you use? (Diameter)

    CNC controller

    When I get that far I will, I figured that I had procrastinated on this project long enough. I thought that If I bought enough of the motion parts, that not being able to use them might just be the kick in the butt that I needed to finish the project. I've got what will probably be the most...

    CNC controller

    For better or worse, I finally pulled the trigger on a DDCS v3.4, 4 axis controller. Don't NEED the 4th axis, but if/when I do, it's there. Don

    3D Printer problems - Monoprice/Wanhao D6

    It's been a while, but I have actually accomplished something. I have received the replacement boards that I ordered from Aliexpress, and I received the replacement relays that I ordered from Omni-Pro Electronics. I was only going to order 3 of the relays, but the way Omni-Pro had their...

    3D Printer problems - Monoprice/Wanhao D6

    RM-MN: I had considered just replacing everything with a standard RAMPS setup. But in addition to having to replace/reconfigure everything if I did that, the Wanhao board is a 24V board and most combo offers like what you listed are 12V boards. I ordered several replacement relays this...

    Small Weekend Projects

    I agree with you Cogsy. When I looked at the drawing all I could think of was "How's this supposed to work?" Once it was explained that became "Now that's a really neat idea." I also go along with what BaronJ is asking about restoring a post. More than once I've spent a LOT of time putting a...

    3D Printer problems - Monoprice/Wanhao D6

    That's the advantage of a 24V board over a 12V board, you're halving the amperage. So those MOSFET's that were at the upper end of their range are now operating at an more comfortable level, at least as long as THEY are rated for 24V. The Wanhao control board has got the LCD drivers, the SD...
