How to run two CNC shields (other one as clone) with one Arduino UNO

I learned a nice thing about Arduino CNC shield today. I have a project coming up where I need 3 axes. On each axis, there will be 2 motors (cloned, running in sync). That means I need a total of 6 motors and drives, but CNC shield only supports 4 drives (axes). So I needed

Wiring and running TB6600 stepper driver with Arduino

A quick post about wiring TB6600 stepper driver which is based on TB6600HG chip. Here I use one without black plastic casing. It has model marking on the back that says “BL-TB6600-v1.2″. Stepper motor used in this demo is 23HS22-2804S (2.8A, NEMA23). Drive looks like this and it’s rated for 4.5A. Looking for more info and photos?

How to use H-bridge HG7881 (HG7881CP) module with external power supply and Arduino UNO

First-time use of H-bridge HG7881 (HG7881CP) module was pretty confusing for me. I didn’t find good (if any?) information about wiring this module up and running it with Arduino. But same time it seems to be quite popular. Here I share how I connected it to an external 12V power supply. You can use any other voltage

Accidentally blew a fuse of Arduino CNC controller by reverse polarity
Today I was messing around with my CNC shield (version 3.00) and GRBL. But somehow I managed to accidentally reverse the polarity of my power cables. Until today I had no problem keeping that in mind. The fuse was blown and like it’s not enough yet- drives also. DRV8825 drives have no reverse polarity protection-

Arduino CNC shield version 3.0 with GRBL v0.9

My experience with arduino cnc shield was bit frustrating at start. This article is about version v3.0 CNC shield. I didn't know anything about this shield, GRBL software and how gcode is sent to CNC machine. So I was pretty unsure about everything I was doing.
