Hi Considering the TMC2100 driver for my i3 that has Nema17 1.7A steppers. I see the specs on the TMC2100 drivers are : I see the specs of the TMC2100 list : Default Vref is 0.65v, Max 1.3V,Min 0. Default Current is 0.5a, Max current is 1A ... does this mean that I can not run my steppers using the TMC2100 driver ? https://reprap.org/forum/read.php?1,764731,764731#msg-764731 Fri, 07 Aug 2026 11:36:08 -0400 Phorum 5.2.23 https://reprap.org/forum/read.php?1,764731,764741#msg-764741 https://reprap.org/forum/read.php?1,764731,764741#msg-764741
If the current is too low the torque is not enough and they skip steps, if its too high they get too hot and skip steps.]]> DjDemonD General Thu, 27 Apr 2017 18:51:36 -0400 https://reprap.org/forum/read.php?1,764731,764739#msg-764739 https://reprap.org/forum/read.php?1,764731,764739#msg-764739
If it will work depends on the friction involved on each motor/axis and the torque delivered at the current provided.

easiest just to try it...]]> Dust General Thu, 27 Apr 2017 18:41:07 -0400 https://reprap.org/forum/read.php?1,764731,764731#msg-764731 https://reprap.org/forum/read.php?1,764731,764731#msg-764731
