Dof reality P3 Nigthmare / need help

Hello everyone i have a big issue with my " 3 dof reality p3 simulator " I punched the P3 rig from them and everything was great for 1 month. The rig broke down and bent a few things. After listening on them for another month i intensively tried to fix my rig. What happened was the BTS760B 43A motor driver that broke. So they posted another one for me. While i was waiting i ordered x6 of them from banggood.com.
But all of them did not work from banggood.com x3 of them exploded and started a fire....

So i told them again and they send send me another control box. Happy days !!! BUT
after i plugged in the new box it took ( 1 day ) And same same the motor 2 BTS760B 43A motor driver went again stop working. So i removed it and use 2 as "2 dof" little later another one went. Then i got one working again and installed it back. Then One week after the USB stop working and i worked it it out that the " fake 9 dollar UNO they have in the box stop working.

So I went online and got me a genuine Uno for $44 au dollar and now the BTS760B 43A motor drivers don't work.

What happens is they don't move up or down when i spin the coupler sensor, they only spin hard ass when i hit the blue line in Smc3 utils and when i turn everything off and adjust it "level" and start it , then the motor lags bad and moves the sensor line up for Evey time it hits it. I have no idea whats wrong and i really want to fix this issue. And is there a chance to avoid the BTS760B 43A motor driver braking down? I nearly spend more money fixing it soon then what the box it worth. If i knew that a $4500 sim would brake down like this i would never buy it !!

Please help i can provide all information clear if it is needed

Thanks

Hi .. somehow it keeps popping the BTS760B 43A motor drivers. why i don't know. I can see the lines in the smc3 utils but its like the green line don't lock on blue line. Its only spinning one way and don't stop.
So i have decided to make it my self.
only need to figure out why its gets overheated and stop. I will buy 3x BTS760B 43A and one sabertooth 2x32. Maybe you know why it keeps breaking down like this?

If you have given up on DOFreality, then the members here would need allot more information to have a chance of helping. Even then, it would be 'best efforts', no guarantees. You say that things were 'bent' when the drivers originally failed, were these bent items fixed?

I took a few pictures of the smc3 utils. All it do is spinning one way and wont lock in sensor line. Motors dont move up or down only spinning..

I have try all options same same spinning violent around one way when green hits blue line.

I learned the hard way Dof reality great support
