Someone however posted stepper motor characteristic with lower torque at higher speed and this is as expected if flux is lower at higher speed. With this characteristic lower max_accel would make sense for higher speed since more torque is needed to accelerate faster. ------------------------------------------------------------------------------ Transform Data into Opportunity.
