This model is designed to make the missing steps issues on drv8825 stepper drivers more observable. If you're noticing weird artifacts on your print and your printer is using drv8825 stepper drivers, chances are your printer is affected by the issue.

I've "fixed" the issues by installing TL-Smoother, If you want to buy the ready-made diode boards that I've explained in the video/pictures, Link to buy TL-Smoother - https://goo.gl/MLxAy0 (updated: set of 4)
This is probably the first torture test designed to make the print looks bad. if your print looks bad, my design served it's purpose :P
- Print speed 50mm/s
- Outer perimeter at 20mm/s or lower (if your slicer can't specific that, just drop the overall print speed to 25mm/s)
- 2 perimeters
- must be printed with the default orientation.
