I’ve previously tested the TMC2100, TMC2208, TMC2130, but still wanted to try out the LV8729 as a ‘silent’ upgrade option. Especially since there is an opinion that TMC drivers are not suitable for use in the extruder.
This video is a step by step to fitting the LV8729, including mainboard jumpers, VREF and firmware changes for both 1/16 and 1/64 microstepping. The steppers are tested in terms of print quality and volume.
Finally, I try to summarise which applications each stepper driver might be most suitable for.
Some notes:
- Never plug in stepper drivers or stepper motors while the power is on.
- Set VREF with the 12V/24V power connected, not 5V from the USB.
- Set VREF with the stepper unplugged.
- Stepper current should be as low as possible to limit heat. If too low, the stepper motors will skip steps. If too hot, they will be too hot to touch.
- The VREF values shown were correct for my Ender 3. Always go through the calculations yourself rather than simply copying mine.
- I am not liable for any damage your cause to yourself or your printer from following this guide.
