Twotrees CNC Controller Kit with Nema 23 Stepper Motor,TB6600 Stepper Motor Driver,GRBL CNC Shield Board，Switch Endstop-6.35mm

Everything assembled & operated properly. A couple of reviews indicated they expected a genuine "Arduino" Uno. The picture only shows "Uno", which indicates that's its a compatible model as all of the 3rd party versions I've come across do. If it were an "Arduino" Uno, the kit would be more expensive.

This is certainly a nice kit for the price, but a wiring schematic would have been helpful. The Arduino board works, but yielded erratic performance, so finally I replaced it with a real Arduino and it solved all my problems. The motors work great and I guess I got what I paid for with the cheap Arduino.

Edit; the machine has been running for 3 years now no trouble, limit switches were a pain, one needs to be hooked up...I cant remember how you have to plug into the board, . I made a 40 inch by 33 inch router and these run great more than enough power.

I bought this kit for a project and it comes with everything you need to build a CNC gantry, the motors work great and everything is basically plug and play. When the package arrived some of the pins on the Arduino were slightly bent, and there appeared to be some corrosion or water damage on the underside. This didn't impact functionality though, just something to note.

Just perfect for some mid range hobby projects. I'm using them to build a new CNC and this kit covers just about all the electronics except for the power supply. The limit switches with pull up resistor and capacitor was a bonus. I ended up getting two sets so I have something for another project. ;-)

Not as advertised. Shipped chinese clone along with no wiring diagram

Todo correcto.

Ordered 2 kits for an upcoming large CNC router + CO2 laser build due to being a full + complete kit at a reasonable price. Didn't need all the parts that came with it, but a better value to get them anyway and not use them. Both kits showed up without the Adruino board. Based on reviews/comments, it is a common problem. Contacted Amazon to send replacements, asked if the warehouse worker could verify kit completeness before shipping the replacements. We will see what shows up in a couple days and possibly update the review at that point.
