Review on 🖨️ MINGDA Rock Pro: Top-Notch Pre-Assembled 3D Printer - 12.6x12.6x15.75 by Fernando Beck

Speaking of which, I knew absolutely nothing about 3D printers. I did a little research and finally settled on this model. I checked out a few YouTube reviews and they all seemed to have mostly positive things to say, especially when compared to other models in this price range. Assembling the device was very easy as only three main parts needed to be assembled with few screws. Once you have everything unpacked, attach the frame to the base, the print head to the frame and you're done. I checked the belt tension and Z-axis alignment and everything was fine with my unit, but I suggest checking yours before proceeding just to be on the safe side. The first days were the hardest. Making the bed was something I didn't know how to do, or even need to do. I've looked at a few tutorials and tried them out. It's a trial and error process, so don't get discouraged if your first few prints look like junk. Your printer is fine; You're just doing something wrong - I'm speaking from experience here. Once you get the hang of what you're doing while leveling, you'll quickly make everything look good. Then the next adventure begins – the software. I'm not talking about bundled software. on the SD card. I didn't even bother installing this and went straight to Cura instead. Cura has a very user-friendly interface, but once you start delving into the advanced options, you'll see how complicated the 3D printing process can be. And that's not this printer's fault. That's the way these things work. I must have typed half a dozen benci before it looked like it should. The two most important tips I can give you are: - Update the firmware. At the time of writing this article, the current version on the Mingda website is 2.8.2. I don't remember what version I had before I flashed it, but I know it was several versions older. - After you have finished updating the firmware, connect the printer to your computer with a USB cable, download Pronterface (google it) and run the automatic PID tuning. I won't go into detail here, but there are many tutorials on YouTube. These are just a few simple commands to help you properly calibrate your printer. I tried to print the first two things using the starter filament that came with the package. Don't even bother. I bought a PLA+ coil from eSUN and when I switched to this thread the difference was day and night. The photos I've attached were printed with eSUN filament after correct alignment and PID auto-tuning. For the 3D printer test, I left it exactly as I took it off the desktop. There was no bridge and VERY minimal strings. Nothing to affect the final quality and easily removed. Satisfied with these results, I set about printing a few useful things. The following images show a desktop headphone clamp with lag screw and solder fume extraction. All threaded parts came out perfectly and everything aligned as it should. As a newbie to 3D printing, this whole experience was a bit frustrating (not for the machine itself) but very rewarding. Once you understand the basics of how it works, you can 3D print anything you can imagine. I have nothing to compare this particular printer to, but I can tell you that after more than 40 hours of printing I have not had a single print error or printer malfunction. If you want to immerse yourself in the world of 3D printing and don't want to spend a lot of money on something, you should buy this printer.
