When homing, slow movemwnt on left side

Greetings all. I`m very new to Gsender and i have a problem. After switching on and connecting i home the machine, the y + z stepper motors move very slowly to a point of misalignment as well as error code.

Im running a jackpot 3 controller with fluidnc webui. If i start it and home using webui a change over to Gsender then everything works perfectly, homing included.

Any ideas ??
