hi, this is the first time i write here, i hope somwon can help me and maby teach me somthing new (im new in this world)

 

I have an old Flying Bear Gost 5 whit marlin software (2.0.9.3), and yesterday i installed TMC2209 v1.3drivers from BigTreeTech. i dit becouse i wase experiencing several problems whit the Z-axis during prints (like layer shifting or very poor quality), and i hoped this would solve them. however, afther setting the vref (following the instructions in this link: [https://all3dp.com/2/vref-calculator-tmc2209-tmc2208-a4988/](to mee result 1.7 for X Y Z and 2 for E)) and changing the drivers in Marlin, when i start auto homing or try to move the z-axis by 10mm, the Z-axis moves non stop until i turn of the power
