Trinamic’s new driver chips are all the rage these days - but there is a catch!

This is pretty much exactly my experiences with them as well. I was able to get printing done on the DeltaMaker with no skipping, but the spreadCycle still wasn’t able to keep our extruder motors going without skipping backwards. Honestly, the way things were situated thermally wasn’t ideal. I was able to get a full 6-hour print out of it though, with minimal underextrusion. Might be worth pairing these with a separate DRV8825 based driver for the extruder, given that it’s typically not moving fast and generating a bunch of noise anyways.
Keep in mind we’re using a direct drive extruder, and our hot end is somewhat known for additional back-pressure due to the 0.35mm nozzle that comes standard. So these drivers may be perfectly fine for driving a 0.5mm nozzle. Additionally, a geared extruder likely won’t have any issue with driving filament. So getting a near-silent machine is very VERY possible given the right attitude and engineering prowess.
@Watterott_electronic has been incredibly open to feedback this entire time, and also makes a lot of great stuff. I hadn’t heard of them before these drivers became available, but they’re very similar to Sparkfun, or Adafruit, just based in Germany.
@Watterott_electronic rules - it’s so much fun to work with Stephan, Abdreas and the team! I can’t wait to try the final version myself.
