Flashforge Adventurer 3 crack printed same height every time

[Nirel]

Guys I need your help.It appears that Flashforge slices my models wrongly (there's also a defective nozzle which doesn't heat enough)But this model, which is without errors in the 3d modeling program 3dsmax, is wrongly sliced in the Flashforge software.Try it yourself, model attached.1. Is there a different slicing program that makes gx code?2. If someone suggests an stl repair service first, please give me the name of a good online stl repair software for free (I can only find payed stuff)Thank you,
