Description
I want independent control of a fifth stepper driver for G34 bed leveling in Marlin by using the EXP-MOT v1 module. My SKR Mini E3 v3 is connected to a TFT35 E3 v3, and thus does not have an open EXP port. There are two open EXP ports on the TFT35, however, so is it possible to connect the EXP-MOT module with a stepper driver to the TFT35 directly? How would I do this? If this daisy chaining is not possible, can I still use both the TFT35 and the EXP-MOT or do I have to choose one?

Research direction
Start by reviewing the EXP-MOT v1, SKR Mini E3 v3, and TFT35 E3 v3 hardware documentation and connection diagrams. Determine whether the TFT35 EXP ports can support the module while retaining the display connection, and document the supported wiring or the incompatibility. Done means the connection requirements and whether both devices can be used together are clear.
