Summary

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)

#SomeRandomThoughts
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

Can I use 1N5408 diodes?

For the TL smoothers to work, you need the boards with 8 diodes.
The boards with 4 diodes do not make enough difference to be worth it.

Which printer did you do this with? I've read people say that TL-Smoother doesn't make a difference in prints for cartesians, only Deltas.

Did you have the high-pitched whine before, and did the TL-Smoother get rid of it? All I'm really interested in is getting rid of that noise.

I made my own and I didn't find that it helped much. I did the mod that forces the DRV8825s into fast decay mode. I've noticed better prints since then.

I tried this model with A4988 driver and no artifacts at all. I think that rather than add the diodes to the DRV8825 drivers why not just replace them with A4088's at half the price?
However the TL smoother would be useful to anyone that has a MKS SBASE controller as they have DRV8825 soldered in.

Yea, you're right. It makes most sense with controller boards that come with integrated DRV8825 or you have specific reasons to keep using the 8825. MKS Mini have DRV8825 soldered in too,

is TL-smooter works on a4988 drivers?
