Hi Everyone,
Im post yet another TMC Connection Error issue. With all TMC2208 drivers installed I am seeing this error from Pronterface, as has been noted in the past.
Connecting...

Printer is now online.

Testing E1 connection... Error: All LOW
Ok, so fine. I read the forums and the help center, and the two paths forward seem to be define the TMC2208 driver as standalone in Marlin and upload it to the printer, or just remove the TMC2208 driver and plugin the A4988 driver, define it in Marlin, and upload to the printer. However, when I do either of these two workarounds, E1 seems to disappear in the checks when connecting with Pronterface:

So my question is...this isnt normal right? This same question has been brought up here before:
However this user also had an LCD issue, and a new board was just issued for that. I apologize in advance if this question was already answered. If there is no workaround except a new board, then Im just going to abandon the dual extrusion.
A workaround can be found here:
The issue stems from a manufacturing error of the control boards, replacing the board unfortunately won't make a difference.
