Setting Axis max feedrate?

Setting Axis max feedrate? was created by EmcRules
Is there a way to set a max feed rate for a single axis within EMC? The reason I would like to do this is due to the Z-axis on my BP Knee. It's a small servo so I need lots of gear reduction to get the tourque I need (30:1). This forces me to slow down all of my feeds to what my Z-Axis can handle due to overspeed faults. Long term I plan to use a larger servo but for now im stuck.

Well the feed rate is set with F in your g code. The maximum velocity for an axis can be set in the ini file.

So if I set [Axis] Max Vel to .1667 = 10 in/min feed rate. in a program i ask for F50. What will happen?

EMC will not exceed the maximum velocity for an axis. In a move with two or more axis the velocity of the move will be such as to not exceed the maximum velocity of the slower axis no matter what speed you program.
