CNC Shield Expansion Plate + 4pcs A4988 Heat Sinks Stepper Motor Controller for 3D Printer Engraver

The CNC Shield Expansion Board + 4 Units A4988 Heat Sinks Stepper Motor Controller for 3D Printer Recorder seems to be a great value for money product. It was bought by a user to convert their old Makerbot Replicator 2 3D printer into a CNC mill and they were very happy with the results. They even mentioned that they decided to attach a laser instead of a spindle, and the shield worked perfectly with both GRBL 0.9 and 1.1. However, they did note that the pinout changes for GRBL 1.1, so potential buyers should be aware of that. Overall, customers seem to be satisfied with the product. Some mentioned that they were building their own CNC machine and this product was meeting their expectations. However, there was one user who pointed out that they only received one stepper motor controller instead of the advertised four. In terms of delivery, most users were happy with the fast delivery and affordable price of the product. However, one user mentioned that the packaging arrived damaged, which is something to Consider. Overall, the CNC Shield Expansion Board + 4 Units A4988 Heat Sinks Stepper Motor Controller for 3D Printer Recorder seems to be a good purchase for those looking to convert their 3D printer into a CNC mill.
