TMC2208 Noisy/grinding when connected to UART #12062

Closed MotoGP1199 closed 6 years ago

MotoGP1199 commented 6 years ago

Description

I recently changed only one of my stepper drivers on the X axis (TMC2208) from legacy mode over to run on UART to test it out. When I did that the stepper now makes a loud grinding/rattling noise when doing fast movements only. I have hybrid mode and stealth chop enabled. Marlin-bugfix-1.1.x.zip

I have a 2130 on my E0 with SPI and it works fine.

The TMC2208 (Watterott) is configures the same as this article. https://www.instructables.com/id/UART-This-Serial-Control-of-Stepper-Motors-With-th/

I have the UART pin from the 2208 hooked up to PIN 40(TX with 1k OHM resistor) and 63 (RX) on the MKS GEN L board. I was running the current (for x axis) at both 800MA and 1000MA and it operates the same.

Marlin (the most current 1.1.x BUG FIX Board. MKS GEN L V1.0

Never mind I figured it out. I was finally able to find some data on the steppers that I have. I increased the MA to 1100 which got rid of the grinding. Also Lowered the Hybrid threshold which helped make it run smoother.

@MotoGP1199 How did you do this, I have the same issue is it a case of changing the

define X_CURRENT to 1100

What did you lower the hybrid threshold too?

Thanks
