@oleksii_solntsev you will need to calculate the maximum linear carriage speed that you need for your printer to achieve the desired XY speed. Our EMF calculator does that for regular delta printers, but not for your inclined tower kinematics.
One thing that worries me about your kinematics is that the Z resolution will vary with Z height, being (I think) worse at low heights and better higher up. Are you certain that you have sufficient Z resolution? Don't rely on microstepping to increase resolution, because microsteps are not necessarily uniform.
