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 […]

Voladd Cloud-Connected Linux 3D Printer is Powered by BeagleBone Black Board (Crowdfunding)

So far, all of the 3D printers that have been reviewed on this blog require you to design or download a 3D object on your computer, and print it from an SD card. But thanks to OctoPrint software and cheap ARM Linux developments boards, it has become possible to add a Linux computer with webcam to remotely start and control the 3D printer for a few dozens dollars. Karl has even released an OctoPrint image for Orange Pi Lite board. Voladd 3D printer already embeds a Linux board, namely the BeagleBone Black running Debian, which allows the 3D printer to be easy to use since no software  installation is required. You can start printing by selecting an object in a web browser or an app in your smartphone, and they’ve also taken steps to eliminate/reduce maintenance tasks, such as the inclusion of a filament cartridge. Voladd 3D printer specifications: Internal […]

XYZPrinting da Vinci Color Low Cost Full Color 3D Printer Combines Filament with Inkjet Technology

3D printing has become even more affordable this year. If you are on a budget, Anet A8 3D printer going for under $150 is often recommended on the web, but if you have a bigger budget, you’d get printer with a metal extrusion frame, larger build volume, and overall better quality, and Creality CR-10 3D printer is often recommended by reviewers for people with a $300-$400 budget. All those printers print with a single color, which depends on the color of the filament used. The cheapest way to get a colored sample is to paint it yourself after printing. There are printers with dual extruder allowing to use two filament rolls with different colors, but when Karl reviewed Tevo Tarantula 3D printer with dual extruder, he found it was hard to print, was unconvinced with the results, and found it to be an unnecessary upgrade, preferring painting instead. At the […]

$99 101Hero PYLON is a Poor 3D Printer, But Could Prove Useful to Learning 3D Printing Technology

Anet A8 was one of the first sub $200 3D printer I found last last year, reviews were surprisingly positive. It is now sold for around $150 shipped (with A8PRINT coupon), and experienced reviewers often recommend it to people wanting to get started with 3D printing on a budget. But last week, as I browsed products on Banggood, I found something even cheaper with 101Hero PYLON 3D printer going for $107.99 shipped with coupon 349da5, and further research lead me to the official website where they sell it for $99 excluding shipping, and provide documentation and video tutorials. 101Hero PYLON 3D printer specifications: Printing technology  – FDM (Fused deposition modeling) Host Material – Steel + ABS XYZ Bearings – Steel Print Size – 100 x 100mm Layer thickness – 0.1mm Nozzle diameter – 0.4mm Printing material – PLA Material Diameter – 1.75mm Power Supply – 20W Dimensions – 260 x […]

Tronxy X3S 3D Printer Review – Part 1: Build and First Prints

Karl here with part 1 of Tronxy X3S build. It is another large volume printer to fully assemble on your own. Taking between 8-10 hours to put together. I have high hopes for this printer. Key things I like: metal frame, dual X, large build volume. Just from looking at it I don’t like the fact that it has no parts cooler but is easy to remedy. Tronxy X3S Specifications Let’s look at some specs. 300 x 300 x 400 mm hot bed (Actually get 330x330x400 build volume) Hot bed temperature: 40 – 110 Deg.C Nozzle temperature: 170-275 Degree Marlin 1.1.5 Frame material: Aluminum Extrusion I have not taken the hotend apart yet so not sure about the nozzle temperature going over 245°C. I will take it apart for the next part. If you are not familiar you don’t want to get lined nozzles above 245°C, or the lining starts […]
