Pitfalls of Pi-CNC board with external drivers

Post by eriklundh » Tue Jul 17, 2018 11:53 am

Last year I bought a chinese 4 axis CNC Router (https://www.aliexpress.com/item/VEVOR-C ... 16122.html)
The software and the copy of planetCNCs proprietary hardware sucked.
I bought the PI-CNC HAT and some driver.
Quickly found out that the currents of the steppers was to high.
Luck had it that I had ordered the Pi HAT with the external driver option.
I bought these TB6600 external drivers: https://www.ebay.com/itm/TB6600-4-5A-CN ... 2385377686
Now I have some time to assemble it all. I will use the PSU and the spindle driver board the Chinese controller box, but scrap the PlanetCNC clone board, replacing it with Pi_CNC with the external TB6600 drivers boards.

Any quick advice on pitfalls?

Have you managed to get the TB6600's working. Lots of people struggle to get them going...
