Fixing the issues related to the software and performance, you will get your money’s worth.


Product Highlights

The MySweety company has had its highs and lows, but at the end of the day, they offer good quality machines for a fair and affordable price.


Now, you should know that this one is not ideal for commercial use, and while you can still go ahead and make it a part of your production line, we recommend you try it out at your own home, and then if you like the efficiency, move it onto the factory floor.


There are a number of upgrades from the previous model. First, it is compatible with most operating systems up to Windows 10 and above Mac iOS 10.9.


Also, it is highlighted by a 775 spindle, and over 10,000 rotations per minute, which is a significant improvement to the 3018 (over 50% less) of the previous model.


Also, one of the most important things, if you are looking to do some high quality work, is the working area – this one sits at 300 x 180 x 45 mm which should be enough for personal use. Talking about the assembly process, this milling machine is not a full-on DIY.


In fact, some parts are already pre-installed while for others you will need to follow the instruction manual, and thus get those set up. Still, the process is quite easy and it shouldn’t take you more than an hour to do.


This product can work with a number of materials both soft and hard, including PVC, wood, plastic, acrylic, and aluminum.


Still, you should be aware that if you are looking to cut some hard metal, it will not be as easy using this CNC router. As for engraving, it can be efficiently done with all the aforementioned materials.


One of the biggest upgrades is that now you can run this machine offline instead of having it connected to the internet or a computer.


By manually opening the spindle, fan, and positioning the starting point you will be able to set the controller and do the work without further steps.


As for the design, we are talking about a lightweight machine made of plastic and aluminum, ensuring its sturdiness on the edges.


Still, it seems that the technical support for this product is not ideal; thus, you should take care of the way you handle the machine unless you want to end up throwing away your investment.
