[BUG] TMC2130 + Rumba32 TMC Connection Error #21650
Comments
Marlin.zip |
What jumpers do you have set under the stepper driver modules? |
Currently i have the pins set like this, this isnt my board but what i used as an example: The stepper driver is a TMC2130 V3.0 from Bigtreetech |
Hi, |
Unfortunately i have a Rumba32 v1.0 from Makerbase, and i tried them all in the lower position without success. |
This is a known fault with the V1.0 Aus3D and MKS boards. There is a connection error in the Chip Select track used for the SPI connections. The workaround is to either modify the board or as I've found, more easily, to mod the TMC2130 driver with a wire link between two pins. The Issue detail and fix is described here: makerbase-mks/MKS-RUMBA32#2 My V1.0 MKS board works fine with TMC2130 with the link in place on the drivers and the TMC2208 drivers work fine in UART mode with the appropriate jumper settings. The link is easily removed from the driver should you upgrade to a V1.1 RUMBA32 board. |
Since this is a hardware design issue, I'm going to close this bug report. |
As stated above I have already tried this fix... |
You do have 12/24volt power applied I presume? I see TMC connection issue if just connected via USB without the main PSU switched on. |
I have 12v applied. |

Bug Description
Hello,
I'm having trouble using the Rumba32 board and my TMC2130's.
M122 gives the following:
I have tried this fix: https://github.com/makerbase-mks/MKS-RUMBA32/wiki/About-RUMBA32-TMC-SPI-%22CONNECTION-ERROR%22-FAQ
But i get the same error. No change.
I know for a fact my drivers are set in SPI as they came like that from the manufacturer.
