OOOOOO T-1 Desktop 3D Scanner Digitizes Objects in Full Color

My keyboard is working fine. Thanks for caring. 3D printing has taken off in recent years, but if you plan to copy an object, you’d have to reproduce it in digital form in AutoCAD or other program, which may be difficult and time consuming. An obvious solution is 3D scanning, and I initially thought that 3-in-1 3D printers that scan print, scan, and copy object would really bring such products into more household, so I wrote about somewhat affordable printers such as AIO Robotics Zeus or Blacksmith Genesis, that would sell for $2,200 and up. The company doing the latter appears to have closed business, and the Zeus is still for sale but some users reported various issues with 3D printing. So if you’d rather not put all your eggs into one basket, it may be smart to purchase a 3D printer and a 3D scanner separately. The price range […]

JGAURORA A5 Review – A Large Build 3D Printer That Works (Mostly) Out of the Box

Karl here and today we are going to look at the JGAURORA A5. I specifically asked Gearbest for this printer. Features and specs looks good. Not to mention that you can go from opening the box to printing in 20 min. Nice large build volume of 305 x 305 x 320mm. Color touch screen. Filament runout sensor. Power Fail feature. Power Fail is so nice. I have lost some long prints due to power going out. I have not lost any for filament because I have always been conscious of it but it’s nice to have peace of mind. The A5 has an assisted leveling feature that is nice. When using this feature there are 5 point that it will go to. One in each corner and one in the center and you adjust the bed. It saves a little time and I believe is standard feature in Marlin now. […]

Embedded Linux Conference & IoT Summit 2018 Schedule

The Embedded Linux Conference 2018 and the OpenIoT Summit 2018 will jointly take place next month, on March 12 – 14, 2018 in Portland, Oregon, USA. The former is a “vendor-neutral technical conference for companies and developers using Linux in embedded products”, while the latter is a “technical conference for the developers and architects working on industrial IoT”. The Linux Foundation has already published the schedule, and it’s always useful to learn what will be discussed about even for people who won’t attend. With that in mind, here’s my own virtual schedule with some of the talks I find interesting / relevant to this blog. Monday, March 12 10:50 – 11:40 – Progress in the Embedded GPU Ecosystem by Robert Foss, Collabora Ltd. Ten years ago no one would have expected the embedded GPU ecosystem in Linux to be what it is now. Today, a large number of GPUs have […]

HE3D K280 Delta 3D Printer Review – Part 2: Upgrades, Calibration, and More 3D Prints

Karl here with part 2 of my experiences with the K280. In the first part of HE3D K280 3D printer review, I spoke about some of the challenges with the K280 getting it calibrated and getting Marlin to work and the initial build. In this part, we are going to look at the new effector, cooling solution I designed, calibration, and general use. If you purchase a machine now you get an injected molded effector and 2 24v cooling fans which HE3D sent over after they saw my initial review. If you purchased a kit before they started including these parts you can pick them up here to upgrade. I would like to point out that this is my first Delta printer. I don’t want to really call this a review but a way to show my experiences. First things first If you purchase this kit I urge you to […]

Year 2017 in Review, Top 10 Posts, and Some Fun Stats

2017 is coming to an end, and as I do every year, I’ll take a look back at the year that was on CNX Software. The pace of development boards launches has not slowed down this year, and we get an even wider range from the low-end with Orange Pi or NanoPi boards, to much more powerful ARM boards, and some new entrants like Libre Computer. The same is true for TV boxes, most of which now support 4K HDR, ranging from ultra cheap models selling for less than $20 to higher end Android TV boxes, while mini PCs were dominated by Intel Apollo Lake models, although some Cherry Trail products were also launched. Processor-wise, Amlogic launched more Amlogic S905X derivatives with S905W/S905D/S905Z, which are popular in the TV box market. Rockchip’s most interesting processor this year was RK3328 quad core Cortex A53 processor designed for 4K HDR Android TV […]

HE3D K280 3D Printer Review – Part 1: Build, Tweaks, and First Prints

Hello Karl here again with another 3D printer review. Today we are looking at an HE3D K280. I saw the brand for the first time on Gearbest a couple months ago and asked for it to review. I never heard of this brand before and have been wanting to review a delta style printer. In my case, I should have been careful what I asked for. It took me quite some time to get it to print utilizing the whole print bed. I experienced several challenges and after defeating them I enjoy this printer quite a bit. Delta style printers mesmerize me with the movements that they make and all the math that goes into moving the extruder in the X, Y and Z. Regular Cartesian printers are rather simple in this respect. Build Volume – 280×600 mm Heated bed No Parts cooling 2020 aluminum and all injected molded parts […]

Tronxy X3S 3D Printer Review – Part 3: Upgrades to Fix Bed Leveling Issues (Permanently)

Karl here. I have had the Tronxy X3S 3D printer for a while now. It prints well but as I mentioned in previous articles I had to level for every print. Actually near the end I would just overpower the stepper motors while the skirt was printing and level. Leveling front to back was not affected. Only the z height. So this worked but it was frustrating. Before that I tried several different things to mitigate. I thought maybe the endstop for Z homing was inconsistent and replaced it. I tried heating the bed for extended period of time thinking that maybe some thermal expansion. Didn’t help. I finally did a major change to the X carriage with success. I even moved the printer to our local library and the bed stayed leveled for a demo. I call this a success, and will show how I did it. Inspiration for […]

Tronxy X3S 3D Printer Review – Part 2: Upgraded Heatbed and RAMPS Board

Karl here. So the bed I mentioned in the first part of Tronxy X3S review is not very good. It took about 10-11 minutes to heat up to 60 deg Celsius. I also mentioned I was going to upgrade the board to a RAMPS board. Today we are going to look at both these upgrades. New Heated Bed I can take no credit for this one but I wanted to pass this along. Folger tech sells a 12v 280w heated bed stick on pad. I picked this up for $20, but is now $22. In order to do this upgrade you will need a MOSFET, 12V/30A power supply, and of course the pad above. Super easy installation. Remove the bed and stick on the self adhesive pad centered. Replace the power supply with new one. Should be self explanatory. In order to power this bed a MOSFET is needed. A […]
