Hi, I have a Kloner3D 300H, a machine produced by a local company here in Italy. I have some troubles with z axis. You can watch it in the video posted below. The motor starts moving at steps, then smoothly, then steps, then smoothly again. It happen with all the latest versions of Cura, but not with the software the producer gave me with the printer. It's a very old version of Cura, year 2016, that they edited a bit. I can't use their version becouse of the poor settings avaiables, so I'm trying to understand why the printer z moving like this. I specify that I can print correctly, but this strange moving doesn't seem to be a good thing for mechanics.https://drive.google.com/file/d/1YiN...ew?usp=sharing
