Hello, I've purchased two TMC2100 steppers from amazon (Ihttps://www.amazon.com/gp/product/B01I4JCABA/ref=oh_aui_detailpage_o03_s00?ie=UTF8&psc=1)
I've enabled spreadcycle on the two TMC2100's I purchased and am having v-ref issues. I'm running a nema-14 for my extruder which is rated 500ma and a nema-17 for Y-Axis rated 1.5A. Both initially work with sufficient torque and are dead silent until very shortly later when they heat up too much. (stepper driver and motor) I assume I need to adjust the V-REF down more but it doesn't allow me to tune it below 1.0V . If you have any ideas please let me know. I calculated that for the Nema 14 to run optimally, I should have a V-ref of about 0.69 V.
Thank you
