TMC2209 v2 (Watterott) low VREF Hi, I just reveived one TMC2209 v2 from watterott and wanted to use and configure it in legacy mode for my MKS Gen L Ender 3 Pro (extruder driver). If I try to set VREF, i can only set values from 0 to 0.09 V. Yes, I measured on the correct pin (middle one), and yes, 24 V are on the machine. Why isn't the VREF in normal ranges? https://reprap.org/forum/read.php?13,861630,861630#msg-861630 Fri, 04 Sep 2026 12:31:31 -0400 Phorum 5.2.23 https://reprap.org/forum/read.php?13,861630,861632#msg-861632 Re: TMC2209 v2 (Watterott) low VREF https://reprap.org/forum/read.php?13,861630,861632#msg-861632 Dust Controllers Wed, 30 Oct 2019 17:18:14 -0400 https://reprap.org/forum/read.php?13,861630,861630#msg-861630 TMC2209 v2 (Watterott) low VREF https://reprap.org/forum/read.php?13,861630,861630#msg-861630
