A new user in the IRC channel noted that the area where DRV8825 drivers are mentioned in the mm-per-step area contains a grievous error. Where it should day "if using DRV8825s then double this value," it currently says "If using DRV8825s, half (halve would be the correct form, nit pick) this value."
This must be causing considerable confusion. I suggest whomever maintains the forum correct this error.
Thank you
