Performance & security by Cloudflare. 0 board and am planning to upgrade to BIGTREETECH TMC2209 V1. One of the first longer prints I tried had terrible Z axis + extruder step loss suddenly about 2/3rds the way through the print, resulting in the nozzle being dragged along the printed surface while grossly under-extruding filament :/ Anyhow, my main question is whether anyone else has made similar modifications to their printer and if they can provide me with their settings for acceleration, Vref, etc. I connected everything up correctly I believe; motors wiring correct, 24V on motor input voltage, 3. 936 or so if you have a rsens of 110, for the extruder anyway, not sure for 2. I did a little research (in case anyone sees this in the future) the TMC2208 are the better option over TMC2209 because of be I bought a set of TMC2209 stepsticks to use with a microcontroller (not a 3d printer project, really just a Teensy spinning a stepper). TMC2209 max out at 1720ma (based on its internal current reporting). If Vref is 1V and the target RMS is 150mA, you can enter a UART value of 375mA which will result in a CS value of 11. Any ideas what could be happening? I'm using the LDO-42STH25-1004CL200ET from my LDO kit with 2209 drivers. 7 V and I have tried different values all the way up to 1. The vref clocked in at 1.
