\"\"<\/a><\/p>\n

For a while now I’ve had an old\u00a0TB6560 Stepper Motor Driver board kicking around, which never really saw much use. I used to drive it from a PC\u00a0parallel port (remember those?) with a very big, ugly old desktop PC running LinuxCNC<\/a>. Because of the size, this\u00a0was pretty inconvenient. Recently, I decided to resurrect it and try to drive it from an Arduino Uno with GRBL<\/a>. It took some time to find the pinout online, particularly since there are several variants of this board with completely different pinouts, so I decided to make notes here…<\/p>\n

This manual appears to correspond to my 3 axis board: (TB6560 3 Axis Manual<\/a>) and here’s the pinout that I’m currently using successfully:<\/p>\n\n\n\n\n\t\n\n\t\n\t\n\t\n\t\n\t\n\t\n\t\n\t\n\t\n\t\n\t

This works but these blue TB6560 boards are absolute junk and have numerous well documented design flaws<\/a> (e.g. skipping steps) which require DIY modifications<\/a> to fix, so if you are considering buying one… don’t. There are plenty of better options available!<\/p>\n","protected":false},"excerpt":{"rendered":"
