I too have been to this rodeo. The maker will not, cannot supply an english version of the vfd manual. Then I noted it was turning backwards so I swapped 2 motor leads, and it ran fwd for about a month while I'm finishing up the rest of the setup. While the vfd has a very plainly marked fwd and rev terminals, they can't be made to work, having no effect. Then last week while wriring up home switches, I noted it was running backwards again, without changing anything that touched the spindle controls in LinuxCNC, so I said screw it and ordered a another 110 volt vfd from the same maker that supplied the vfd for my Sheldon lathe conversion. Then today, while adding the last home switch, I noted it was running fwd again. You will likely be time, but not money ahead to pitch that whole box and do what I did, which was replace the motor drivers and their psu with something that can actually do the job, a 500 watt 40 volt psu and a stack of 4 2M542 drivers. The supplied 24 volt supply goes into foldback when the rotary is plugged in, running at 14 volts. Ditch it and put in something that can actually drive motors at 200+ IPM. And since the vfd isn't sure which direction to run the spindle motor, just ditch the whole box. The rest of the machine isn't too bad although it could use bigger X rails for improved rigidity in the y direction. If you could buy the machine sans that box of crap for around $800+freight it would be a good buy. For $1350 with freight and zero support, leave it in the box in the Chinese warehouse and get something else. You'll be happier in the long run. I've got it, I'm stuck with it, so I'm sinking additional money into it to get a working machine. Probably close to $2500 by the time its running well.

im sure in one of the setup videos i watched allowed u to change motor rotation in the mach3 software
