Good kit.
Very good kit, however I had some problems setting it up. Those problems were due to wrong firmware on my computer though, so this kit is not at fault. Everything pictured was nicely packed in individual static bags for: 4 A49888 Stepper motor drivers, 1 CNC shield V3.0, One Arduino uno clone, and one 2 ft usb cable. Jumpers needed for operation are NOT included.

COUNTERFEIT PRODUCT!!!
ATTENTION: This is a counterfeit Arduino UNO board. The product description clearly states “Arduino UNO R3 Board.” However, what I received was a knock-off counterfeit board. If I order and pay for an Arduino brand board, I want to receive an Arduino brand board.

Garbage!! Don't waste your time!
Extremely frustrated with the CNC Sheild. Never got this to work after spending a long day debugging and reinstalling grbl multiple times.

Does not support GRBL 0.9
I just bought 6 of these to teach a class with. 1st - They are not GRBL 0.9 compatible. They are GRBL 0.8 compatible. The difference is they swapped pin 11 /12. This means if you run the latest GRBL(1.1 at the time of writing this) the Z axis will not work and the spindle enable / laser enable pin Will not work.
