CNC Shield. This is a faithful copy of the V3.0 board produced by www.protoneer.co.nz There is some great info on this setup at http://blog.protoneer.co.nz/arduino-cnc-shield/ with a step by step at http://blog.protoneer.co.nz/arduino-cnc-shield-v3-00-assembly-guide/ One important thing - NEVER power up the board without there being stepper motors connected to each driver module. Failure to do this WILL destroy the driver modules.

- Haute qualité 👍 - Emballage fin 📦 - Et reçu en moins de temps ⏰. Honnêtement la meilleure expérience de magasinage en ligne 😍 😘 👏👏
This is a good controller for CNC machines. Heatsinks have double sticking tape for placing them on top of chip. Drivers have no led to see if signal is present. I found solution of motors not responding by reading ALL reviews and one frenchman said there has to be a jumper at EN/GRD pins, close to button. No jumper in package so I made one. The drver chip gets very hot with stepper 42BYGH47-401A at .98V reading in driver. Have to tweack a lot and learn much more electronic theory to make it run well.
Purchased to run a GRBL build as a CNC router controller. Beware the pin alignment between the UNO, CNC shield and A4988 boards - i had to re-align some of the rows of header pins / sockets to allow the boards to assemble. Tested the UNO board - connects to the Arduino software and have downloaded a test program without issue. Note this board uses the CH340 USB-to-serial chip which is known to have an Rx buffer over-run issue with GRBL. On the CNC shield, the EN/X/Y/Z/A/5V headers (blue - top left) are not inserted all the way and are misaligned with the matching yellow headers - in my case a jumper won't fit to these without re-soldering. These headers are only used for development so i don't think it will matter initially. The shield is stamped as v3.00. The latest GRBL build (v1.1) and genuine Protoneer CNC shield (v3.51) have swapped the mapping of spindle enable and z-axis end stops; if using this shield with the latest GRBL the user needs to consider the implication of this. Solder quality seems fine across all boards. Entering into this project i was unaware of the specifics regarding the genuine vs. clone boards. I'll try these to see if they will work (i expect that they will) but i do so knowing that if they don't i'll be purchasing genuine boards to finish the build.
Good controller board for this price. Comes with arduino uno clone and stepper motor drivers. (and heatshink for drivers) Just need make motor-cable and burn grbl software to arduino and get a cnc controller. Arduino borad has excelent quality. Some drivers, and a shield comes with curved, crooked pins (maybe the shipment, post office handling badly.), but easy to fix this with a plier.
Packaging was good delivery time only 1 week. The product works very good no parts missing.

Alles was man braucht für eine Motorsteuerung. Gut verpackt und eine schnelle Lieferung. Prima
Good and useful. this is my second order for laser engraver.
