plugin for joysick

[valhallaCNC]

I have pokeys57E and using an analog joystick. Works fine ,but noticed one odd thing. For step moves I have been using AddLinearMoveRel(int Axis, double Step, int StepCount, double Speed, bool Dir) . In the speed field. If I use the variable from the joystick analog it changes the base feed rate from the entered amount. I have to manually change it back. I can use a fixed number in the speed field. It still changes the entered feed amount by some sort of ratio for example if I use 25 instead of the variable, the feed is about 112 on screen, how is that calculated? Is this how it is supposed to work ? Am I missing something. Thanks Joe
