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

thingiverse

This is a dual TB6600 stepper driver external mount box and lid. Made this for Tevo Flash, but this will most likely fit Tarantula Pro, Ender-3, Geeetech A10 etc etc. which have similar structure. This allows you to put proper power into the motors, adjust VRef until motors are around the 70C mark. Typical stepper should be safe upto 110C. With the extra power you can increase your speed settings dramatically, to the point where 8bit ATMega based boards can be a serious bottleneck. With quadruple stepping a typical 8bit board is limited to 800mm/s at 1/16 microstepping. On the other side, you can ensure you never skip a step 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 you at the 30-40$ mark depending how much DIY you want to do. You also need M3 assortment, a bit of wire etc. A few M5 T-Nuts for 2020 extrusion, and a few M5x10 or M5x8. Box has printed threads, but at M3 size do not overtorque them. Used M3x4 on the drivers, M3x8 on the lid. https://youtu.be/y6aa6glxFno
