But the comment doesn't actually seem to have made it into the firmware. I recently upgraded an old Rostock MAX v1 to what is now effectively a v3, which is great, but ittook me a while to figure out why my extruders were skipping - would have saved me some time if the comment had been sitting there in the firmware where I would have seen it right off the bat. Maybe look into if the commit got lost somewhere along the way?
