Changelog
Compiling changelogs from previous releases
- TMC E-Stop handled even during calibration by pausing and disabling driver
- E-Stop checked correctly after startup. You can now disable force and delay startup by setting E-Stop during startup.
- Digital and Analog sources are disabled by default

Status: IN DEVELOPMENT! Not a final design
Info: If you experience issues with the stability/usb connection/noise with the TMC driver and the FFBoard in versions until including 1.2.2 try to isolate the middle 2 standoffs between the stm and tmc board or replace them with nylon standoffs. It seems like they are a bit too closely coupled to the power part of the driver and cause a ground loop depending on your setup. In the next version i will try to increase the impedance and path length a bit between the power and the digital sections. Increasing the groundplane distance reduces noise coupled in from the power stage.
