Hi all, im having trouble and frustration for the past week. And finally my issue is solve and wish to share my experience to all. But of course, its just happen to my setup only. Machine; Ender 3 Mainboard: SKR Mini E3 V1.2 BL touch For installation of the direct drive kit, please follow Teaching Tech guide on youtube "Complete Hermera Setup" VREF setting for TMC 2209, please change to 840 instead of 940. Im using Sainsmart 95a TPU and the setting is Layer height 0.24mm Reaction Distance 1mm Reaction speed 20 mm/s Print speed 40mm Hot end temp 215 Other den VREF setting, the rest is quite easy to solved and the Hermara prints good. For V6 hotend, some PLA or Petg will just clog and had to open up and service. Sorry for my poor english and hope everyone have a happy printing exprience.
