My respect to those here,
I bought a 600mm Vevor machine on Ali-express, which I kept with appropriate compensation, I sold it after informing the buyer about the defects. After that I bought the MX-S716G. If I find this forum first, I will definitely not buy. Since I found it mechanically fine, I kept it with $260 (price 883$) compensation. The agreement was reached after more than 10 exchanges of letters, I threatened them with the EU review body. Rewiring the electrical wiring is easy, the On/Off switch must be connected directly from the spindle protection switch. The wire of the direction changer that goes to the On/Off switch must be thrown away, For me, this wire is red. After that, there is normal mode,no need to mess with the direction switch to work properly. Switching sequence Green button, main spindle stop , display lights up or shows the revolution. Unfortunately, it also rotates at 126/minute by default, there is no 0 position. I installed a spare switch which interrupts or closes the input wire of the direction changer (R - L switch). This is how I exclude immediate spindle rotation after switching on. I am currently building the digital threading (automatic feed), so the end of the spindle is bare. Sorry, the comment was a bit long. Regards, Imre from Hungary
