Dual TB6600 Stepper Driver External Box for common cartesian printers (Tevo Flash, Tarantula Pro etc)

thingiverse

This is a custom-built TB6600 stepper driver external mount box and lid. Made specifically for Tevo Flash, but this enclosure will likely fit Tarantula Pro, Ender-3, Geeetech A10 etc. which have similar structures. This setup allows you to provide proper power to the motors, adjust VRef until motors reach around 70C mark. Typical steppers should be safe up to 110C. With extra power, you can significantly increase your speed settings, making 8-bit ATMega based boards a serious bottleneck. Even with quadruple stepping, a typical 8-bit board is limited to 800mm/s at 1/16 microstepping. On the other hand, you can ensure that no steps are skipped and even increase microstepping to 1/32. These drives are cost-effective and can handle north of 40V 6A. You can get these cheaply from MakerBase (MKS). This total kit will run around $30-$40 depending on how much DIY you want to do. You'll also need an M3 assortment, some wire, a few M5 T-Nuts for 2020 extrusion, and a few M5x10 or M5x8. The box has printed threads, but at M3 size don't overtighten them. I used M3x4 on the drivers, M3x8 on the lid. https://youtu.be/y6aa6glxFno
