To bad you can't feed the MKS bords from the RasPi. AFAIR, it's 5V regulator is much beefier than the faintharded Arduino stuff.

So after a lot of swearing and googling every single parameter I found something interesting about the PWM Scale (Y Axis Overdriving and Blowing Driver)

One of those guys got in touch with Watterott and was told that the USB Cable (more the 5 Volts) which is connected to a raspberry Pi in my case, can cause some wierd stuff on the Y driver (high current... just read it yourself). So I thought what can I lose ordered a new MKS Gen1.4 and connected everything except the Raspberry.

And now everything works just fine and this damn y-motor is quiet. :D

Seems to me, the register got overwritten by a FW-routine. You have to find a different pin for Y_CS. Preferably ALL Y-pin assignments should be in the same register, but we don't know, since MKS is closed source... :(

At first I had a connection problem where the y-rigster in the M122 output said

Recv: 	Y = 0xFF:FF:FF:FF

since I had no idea what I can try anymore I got me a new MKS GEN 1.4, i uploaded the FW connected everything and started the printer. I than moved the Y-Axsis and no noise. So I thought, great the old board was broken. Than I checked the M122 Output and it was similar to the one i posted two day ago. I noticed the wierd numbers but thought if it works that is fine with me. But after that I moved the Y-Axis a second time, again high pitch noise.

Well it is not a hardward problem right? Since the there is a connection? I am currently using the D64 pin as CS pin. All other CS pins are default. Could it be that I cannot use this pin?

I used the default y pin before, obviously same result.

So is there anyway to change the register by hand?

Right, I missed that.
It seems the Y-driver didn't communicate over SPI and hasn't received it's setup. This could be related to the different register, but I'm no expert.

Whats up with the numbers at treshhold and [mm/s]?
Well I dont know why it shouldn´t work with another register/timer?

Recv: Driver registers:	X = 0x80:0D:00:00
Recv: 	Y = 0x81:0E:00:00
Recv: 	Z = 0x80:09:00:00
Recv: 	Z2 = 0x80:0D:00:00
Recv: 	E0 = 0x80:0A:00:00

The Y-driver seems to be controlled from another timer/register.
That's the only difference I could find, but don't know if it matters?

Hey guys :)
I am currently building a 3D Printer with much inspiration from that: [www.thingiverse.com]
However after a lot of troubleshooting I got most off it working, expect the y-motor is making a highpitch noise when it stands still.
I am running 5 Watterott TMC2130 on a MKS GEN 1.4 with Hardware SPI.

I´ve tried everything: switching motors, connections, stepper. So I guess no Hardware problem?

I think, I setup something up wrong in the MarlinFW. So I tried different configurations but cant get this damn motor quit. :?

I have no idea what I could try anymore. I know there are some strange things in the M122 Output at Y, but I dont know what I have to tune to get it right.
Any Ideas?
