Issues With Skipped Steps Recognition

I recently got the Duet WiFi for my CR-10S5 and i'm working on tuning skipped steps recognition. I thought I'd start with the X-Axis, and then move on to Y. The command I've put in config.g is as follows: M915 X Sxx F0 H50 R2. If I set the S-Value to anything below 30 it falsely detects lost steps every time the axis moves, however if I set it at 30 or above, it wont detect lost steps, even if I force the axis to skip. I am very frustrated and would greatly appreciate some help!
S30 is much higher than normal, and H50 is much lower than is typically viable for reliable stall detection. The Trinamic datasheet for the stepper drivers states that 1 rev per second is typically the lowest speed at which an impending stall can be detected, which is why H defaults to 200 in the M915 command. I suggest you start by leaving H at the default value of 200, which should allow you to use lower S values.
