I suspect in Dermot’s case he was using Inches/sec for speeds, meaning everything was going 25.4x faster than he expected, and the controller was capping it at the maximum speed. For this, use the Inch / mm/sec mode so speeds are still in mm/sec.
For Ben, since you’re on an Eleksmaker diode, your controller probably has a maximum speed set as well, and you might still be in mm/sec mode, not the more common mm/minute used for slower systems.
