Gantrykins G0 Z axis max speed was created by alexMV
Hello! I have a problem with my 3-axis gantrykins machine. X and Y have max speed 15000 mm/min (rack and pinion), Z just 4000 mm/min (ball screw). I wrote the same MAX_VELOCITY for each axis, but when I do G0 the machine drives Z with max speed 15000 mm/min (MAX_LINEAR_VELOCITY ). How to solve this problem?
Thanks!
Thanks!

In your ini file, change this for your Z Axis
it is in mm/second not per minute so 4000/60 = 66.667
[AXIS_Z]
MAX_VELOCITY = 66.667it is in mm/second not per minute so 4000/60 = 66.667

In ini file I have already write MAX_VELOCITY=66.667 for Z and 250 for X and Y. When I run G0 code the machine do this command with max speed by X/Y=15 m/min and Z=15 m/min despite Z speed limit. This problem appears only in gantrykins. When I try to control the machine in trivkins all is well. How to set Z speed limit correctly in gantrykins?

You should consider switching to version 2.8 and using the gantry-compatible trivkins there.
