HiLetgo 2 x CNC uitbreidingsplaten, V3 Engraver Shield 3D-printer CNC Expansion Board A4988 driverboard voor Arduino

Arduino互換機でステッピングモーターを回してみましたこれで少し自信が付き、自作ＣＮＣ用にモーターと共にもう一台注文しちゃいましたこの値段で、こんなことができてとても満足しています

The CNC shield just arrived yesterday and I haven't had a chance to put it together and run it. But from what I have seen of the board so far.... It fits the Arduino uno with no issue, The soldering is good, the sockets are solid, and it's well labeled. I would say at this point that it was money well spent and I look forward to completing the build up to a finished CNC controller.

Muy buena calidad, instalado en un grabador laser, funciona muy bien con GRBL

I’m using one for an “Eggbot” clone (running EggDuino firmware) and one for an X-Y drawing machine (running GRBL firmware). Both are working well with no issues.One thing to watch out for is the way this shield is powered. I recommend you ignore any Instructable (or other project source) instruction that tells you to draw power for the CNC shield from the Arduino VIN pin. Instead, run a 12VDC adapter directly into the barrel jack on the CNC shield. The shield is built for the high current require to run stepper motors, the Arduino is not. Besides, you will have a computer attached to the USB port of the Arduino anyway and that will provide all the power the Arduino needs.

レーザー加工機の制御に利用しました。不具合無く動作しています。容易にCNC制御が可能となり次回も利用したいと思います。
