    Hi, what is the price on this? I mean, is it less than the Bambu A1 combo? Is there a reason to NOT get the Bambu and get this one instead? A like for like with a proven track record on one seems like the price would have to be VERY attractive .

    The Anycubic Kobra 3 Combo is currently on sale for $450, which is about $40 less than the Bambu A1 combo on sale. I don't yet have enough testing to be able to compare them, but that proven track record is a good point to keep in mind.

    This hardware DESPERATELY needs better software. At launch there doesn't appears to be a way to adjust the filament change waste or even remove the purge block. So multicolor prints literally use more wasted filament than filament for the actual print.

  • @HoffmanEngineering
    @HoffmanEngineering2 күн бұрын

    I'm still getting to know the machine, but there is a purge setting in the ACE tab on the printer that you can tell it to extrude more or less when wiping. You can't change if there is a purge block or not from the printer since that's part of the gcode, but the Anycubic Slicer does let you remove the purge block. There is a crazy amount of waste though when switching colors. The 4 color gyro example print is 60 grams of filament, but produced 221 grams of waste. It's certainly something I'm keeping track of to see if there's any good way of reducing it.

    What about motocycle or car parts. I guess if it handle a full body, might be good for motocycle but not sure for a car.

  • @HoffmanEngineering
    @HoffmanEngineering3 күн бұрын

    With markers, I'd expect car and motorcycle parts to work pretty well. Creality has examples of a full car body on their website. You'd need to use a laptop for it, since you'd be moving around a large area.

  • @Todestelzer
    @Todestelzer3 күн бұрын

    They have to improve the software. No orthogonal view what it makes deleting stuff complicated and it’s deleting the original scans after merging. No alignment function to a coordinate system. No auto alignment using markers when fusing 2 body’s. (As far I know. There is no check mark to select for Auto alignment)

  • @HoffmanEngineering
    @HoffmanEngineering3 күн бұрын

    That is a good list of suggestions right there! The alignment workflow could definitely be approved, it was the only part where I struggled.

    The otter and raptor are really an amazing contribution to so many fields of technology. Thank you so much Creality, I commend you for your tireless efforts to help progress humanity. I had a thought/ brainstorm, could you use a clear transparent base to locate the octopus on. That way you could scan right through the underside of the base, and create data without having to flip it over? Food for thought. Please keep making informative content on how to use the Creality scanners. 🇦🇺🤜🏼🤛🏼🍀😎☮️

    @HoffmanEngineering3 күн бұрын

    I appreciate the comments! I agree, the Otter is a pretty good leap compared to similar handheld scanners of just a year or two ago. The transparent base is interesting. I'll have to see if I have anything that's transparent to infrared light. But if you can find a base like that, then I think that would work!

    Unfortunately I have not had the chance to try the Revopoint Mini. I'll try and get my hands on one though to test out. The Otter gives better results than the Revopoint Pop2 I last used, but that is a few years older and less expensive, so not really a fair comparison.

    It would be nice to have some kind of test to check the accuracy. For example scan screws of different diameters and print them. Than test what is the smallest diameter which fits the corresponding nut.

  • @Todestelzer
    @Todestelzer3 күн бұрын

    That wouldn’t be accurate. You need to measure points in the point cloud. If you print it you add the printer tolerance. The printer x/y calibration, Flow calibration, pressure advance calibration and material shrinkage. The accuracy of the scanner is listed as 0.02mm. In general that means around 0.05mm accuracy in real world scanning. You can use cloud compare to measure point cloud distances for example.

    The 14k screens are also physically larger, so just because the resolution is higher doesn't mean the pixel size is smaller/denser. The math checks out for the longer's subpixel to be 10.5 microns.

    Be aware of Tyvok products!! They do not preform has they advertise! The 20wlaser is equivalent to other brands 5w laser. Worst part is Costumer service! They will not refund or resolve if you have any situation going with the laser. Be also aware of their "free Shipping", its is free but only until you receive contact from the customs saying you have taxes and shipping to pay

    Note that - unless yours was different the Jiccota is a class 1 laser (which does not require eye protection - unless of course you stand and stare at it.) What that means is that in normal use as long as you dont constantly look at it, the reflected laser won't hurt your eyes. HOWEVER you are right to warn people to use protection because there are so many variables that not taking the chance is a good thing. PS a Class 4 laser is the one you have to be paranoid about.

  • @HoffmanEngineering

    This is definitely a class 4 laser (as indicated on the side of the laser module and the front of the control panel). Eye protection is REQUIRED for anyone around the laser, or you will damage your eyes.

    You forgot to mention that support for this item is trash. First of all, you cannot purchase spare parts such as certain cables, the x-axis adjuster, or even a laser module to use as a spare. My autofocus failed. which seems to be common for this model (google it), and support could not fix it. The flame detection failed and the laser continued to burn and did not return to the "home" location causing the laser head to melt. Atezr would only replace the laser head with a 5w laser and stated it would work on my machine. I'm still fighting with them to honor their warranty... 3 months later.
