GMK NucBox2 Review – Windows 10, Unraid OS on a Coffee Lake mini PC

GMK NucBox2 Review

Karl here. Today we are going to look at a mini PC. It is by GMK. GMK’s first foray looks to be the NucBox, a super tiny mini pc. I would call the NucBox2 its older, bigger, more capable brother. What stood out to me was the M.2 4x NVMe slot. I don’t anticipate a superfast SSD to come with the NucBox2 but we will see. The NucBox2 only had one 8 GB stick of memory and I had an extra stick laying around so I installed it to get dual-channel support. I think they are doing this mini PC a disservice using memory in single-channel mode. A quick Google search shows an 8GB stick is about $50 and I would highly recommend this upgrade.

Ortur Laser Master 2 Pro laser engraver – First impressions

Ortur Laser Master 2 Pro review

Hey Karl here. Today I am here to share my initial experiences with the Ortur Laser Master 2 Pro laser engraver. That is a mouth full so I will refer to it as the LM2Pro for the remainder. The LM2Pro is the successor to the Ortur Laser Master 2. I have only had 1 experience with a diode laser and that was quite a long time ago and a lot has changed in the desktop laser department. I have used the LM2Pro for almost 2 weeks and I am blown away by what I have been able to achieve in such little time. I don’t know if it is better software or the machine itself. Probably a mixture of both. There are 3 different models with different power lasers. The 20W version was sent for review. It is dishonest to call this a 20w laser. I am not sure which […]

Genmitsu 6060 XY-Axis Extension Kit for PROVerXL4030 – DIY desk and folding cart

Genmitsu 6060 XY-Axis Extension Kit

Karl here. I teased this article in the final review of the Genmitsu PROVerXL 4030 CNC Router. I was really happy with the base kit. You can check out all my thoughts there. SainSmart recently released an extension kit that I have now had for a few weeks. It increases the stock size from 300 x 400 to 600 x 600. That is what we are here to check out today. When I inquired about the kit I didn’t realize how boring a review of the kit would be but I will do my best to bring some additional value beyond just unboxing and building experience. Unboxing The parts list is minimal 2x Y-axis Aluminum Extrusion (lead screw included) 2x X-axis Aluminum Extrusion (lead screw included) 2x Front/Back Plate 7x Drag Chain 9x Drag Chain 4x Hexagonal Wrench, 4mm, 3mm, 2.5mm, 1 mm The original kit came with some decent […]

Genmitsu PROVerXL 4030 CNC Router Review – Mods & Projects

Sainsmart Genmitsu 4030 review

Hey, Karl here. Today I am writing about my opinions on the Genmitsu PROVerXL 4030 CNC Router and sharing the projects that I have done. My initial review was published back in January. I have been working with the tool for several months now and I have had a lot of fun. I have also gained a ton of experience and am really proud of what I have been able to make. I attribute my success to doing my homework and not doing my usual feet first approach. Let’s start with my opinions then showcase the projects I have completed. First opinions. The machine is well thought out and the build quality and materials are good. Other than a few modifications I outlined in the first part I have done nothing else. I installed an rpm meter but found that it was unnecessary. I don’t even look at it anymore […]

Sainsmart Genmitsu 4030 review – Unboxing, mods, and first cuts

Sainsmart Genmitsu 4030 Review

Karl here. This will be a long one but I haven’t had this much fun with a product review in quite some time. I don’t consider myself a complete noob with CNC routers but I have only scratched the surface. Learning new things really drives me and being able to make more permanent things is very satisfying. I have some experience with the Sainsmart 3018 CNC router. I had a lot of fun with it but the build volume was on the smaller side so really limited on what can be done with it. I still recommend it as a starter CNC router and as a good stepping stone to get your feet wet and the Genmistu PROVerXL4030 as the next step. I was able to make some cool things with the 3018 and I hope now to take it to the next level with the Genmistu 4030. Before we […]

Ender 3 Pro 3D printer in late 2020 – Build and first prints

Ender 3 Pro review 2020

Karl here. How does the Ender 3 Pro 3D printer stand up in late 2020? The short answer is pretty well. With just a few minor gripes it is a solid printer. According to All3dp the Ender 3 Pro came out in September 2018. Over 2 years ago. It is the successor to the most popular 3D printer: the Ender 3. I usually don’t do any research so I won’t be influenced by other reviewers but I did in this case so I could see what the differences are between the Ender 3 and Pro versions. It has been upgraded to a Meanwell power supply. Better mainboard layout. Wider extrusion for the bed to ride on, which should make the bed more stable. If you have done any research on 3D printers I would say it is impossible not to have heard about the Ender 3. With its low price, […]

Kywoo Tycoon 3D Printer Unboxing and User Experience Review

Kywoo Tycoon 3D printer review

Hey, Karl here. A lot of our readers know I do most, if not all of the 3D printer reviews for the site. I feel very fortunate to be able to review them. It does take quite a lot of time but sometimes a gem comes along. I was fortunate enough to be chosen to review and share with you a new printer from Kywoo. The Tycoon 3D printer ticks all the boxes I have been asking for. Easy assembly Direct Drive Linear motion (Rods and rails in this machine) Smooth filament holder Touch Screen Auto Bed leveling (Until now I didn’t know I wanted this…more on that later) Rock Solid frame There are a few shortcomings and I hope what I am sharing is addressed before the final shipment. I will go into more detail later on. As far as the physical printer I am super happy with the […]

Testing PTFE Tube for 3D Printing

PTFE Tube for 3D Printer

Karl here. I’m back with a short article on some testing that I did on PTFE tube. When I received the Sovol SV02 3D printer it came with some baby blue replacement PTFE tube. It came preinstalled with the regular white stuff that most Bowden style printers come with. I have also been thinking about different ways to use the Retraction Calibration Tool I created. I recommend reading it first to get grounded on what this tool does before going further. I have always heard that Capricorn brand is the best so I purchased some on Amazon. I will test 3 kinds. Generic white, Baby blue Sovol, and Capricorn XS tubing. (Now that I am finding the links to add to the article I see that it is through the Sovol Amazon store. This is just a coincidence.) For the uninitiated, this little tube plays an important role in 3D […]
