I have never been able to find much info on how to tune the trinamic drivers in our printers, so i assumed it was cause their was no real need but i have found that it is a huge way to improve performance for free. The biggest thing is if you get jams from your extruder motor getting to hot as i saw a 20c drop in temp on my orbiter motor.
