UART Mode not working even on 24VDC #41

arnaud21270 commented 3 years ago

Hello, I have TMC2225 Drivers, I put the jumper regarding the tutorial and configure marlin bugfix 2.0.x to use uart mode on 4 drivers (X, Y, Z, E0), I switch on 24vdc but when I test the UART state I got this :

any idea? Thanks in advance.

Hi! Are you set driver type in Configuration.h file image

arnaud21270 commented 3 years ago

Hello, yes I have done it like in your example as it says that for TMC2225 we must adjust TMC2208.

mks-viva commented 3 years ago

Use uart mode:

  1. Jumpers set(X Y Z E0 use uart mode) and you need use MKS TMC2225 connect to MKS SGEN_L V2 motherboard image
  2. Marlin configuration.h file set image
  3. You need use DC12-24V power on。

It is exactly what I've done, but when I send M122 I get the message I've post on the first message. Subject is not closed! thx

arnaud21270 commented 3 years ago

ok it is still open but what next?

mks-viva commented 3 years ago

Provide your firmware to me and i will use it test.

arnaud21270 commented 3 years ago

Please found here: picture of the jumpers, picture of the stepper in position, firmware.bin, configuration.h, configuration_adv.h, a screenshot of the results of M122. I have now 5 stepper because I just ad a second extruder to my machine.

mks-viva commented 3 years ago

Oh No! I always thought that you are using MKS TMC2225. If you are using MKS TMC2225, then you can use Uart mode directly by plugging it in, because MKS TMC2225 mode supports Uart mode. However, if you are currently using the TMC2225 module of another manufacturer, you may need to set the TMC2225 module to Uart mode according to the manufacturer's instructions, and may need welding or flying wiring.

arnaud21270 commented 3 years ago

ok thanks, I just see the issue with the stepper. The pins doesn't match with your version.

mks-viva commented 3 years ago

Yes, if you use MKS TMC2225 directly, then no welding is required

arnaud21270 commented 3 years ago

I will check if I can try to wire the drivers I have to use uart mode. Thanks for your help, you can close the subject.

mks-viva commented 3 years ago

Ok! I will close this issues temporarily.
