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 and just run full speed all the time. I test […]

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 get started here are the important specs: Working area – […]

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, print quality, and community support I can see why it […]

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 one exception. The rest of the critiques are user experience. […]

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 printing. It provides a filament path from an extruder to […]

Sovol SV02 3D Printer Unboxing and First prints

Sovol SV02 3D Printer Review

Hey, Karl here. Back in September of 2019, I reviewed the Sovol SV01 printer. I had a very good experience and still recommend it to this day. Fast forward a year and Sovol is back with a new version, the SV02. The SV02 is a dual extruder single nozzle printer. This will be my 3rd dual extruder 3D printer… The first 2 I did not have a very good experience with. Sovol sent over this printer at no charge for review purposes. I am going to share my experience a little differently this time. Instead of 1 long article, I will break it up into bite-size pieces. In this one, I will share my initial impressions and first prints. The new 3D printers I have been seeing have not been very exciting lately. They all basically have the same features and only minor differences and the SV02 is no different. Sovol has 2 avenues to differentiate themselves. Customer service and […]

3D Printer Retraction Calibration Vol II – Calibration Generator Program Release

Calibration Generator Program

Good day. Karl here. It has been a while since I have submitted any articles. I got burned out and my normal day job picked up considerably. I have been keeping busy but not with anything I would share by itself. I will start out with an update on what I have been up to. You can skip to the 3D printer retraction calibration section with the release of the Calibration Generator tool if you are not interested. What have I been up to? First, I have been doing a lot of gaming. Been playing Fortnite, Red Dead Redemption 2, and some other random games. I am trying hard to keep up with my son. Unraid OS. So many things to explore and learn. Docker, VM’s, and storage. There is so much goodness in this OS. I was able to consolidate several services into one box. I had a standalone NAS drive that I went way too long trusting my […]

How to Recover from a Bad Firmware Upgrade on Anet ET4 3D Printer

How to flash Anet ET4 Firmware

Hey, Karl here with a really quick how-to. This how-to is to help everyone who has bricked their Anet ET4 printer after upgrading firmware on the printer. Anet reached out for a review of the ER4 and I recently gave one printer to a buddy of mine and he showed a lot of enthusiasm. I thought it would be interesting to do a review from someone less experienced. I asked him if he would like to do it and he accepted. I wanted to help him with unboxing and initial setup so we fired up a YouTube Livestream. The build went smooth but because the UI is lacking finish I went searching for updates. It is not uncommon to flash firmware, and after a little googling I found updated firmware and was hoping to fix the UI. We followed the directions but the machine got hung at the logo after rebooting. Damn. After a little more searching found directions from […]
