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... start Printer is now online. echo:Marlin 2.0.5.3 echo: Last Updated: 2020-03-31 | Author: (none, default config) echo:Compiled: Nov 1 2021 echo: Free Memory: 3141 PlannerBufferBytes: 1232 echo:V76 stored settings retrieved (704 bytes; crc 6522) Testing X connection... OK Testing Y connection... OK Testing Z connection... OK Testing E connection... OK 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: Connecting... start Printer is now online. echo:Marlin 2.0.5.3 echo: Last Updated: 2020-03-31 | Author: (none, default config) echo:Compiled: Nov 1 2021 echo: Free Memory: 3229 PlannerBufferBytes: 1232 echo:V76 stored settings retrieved (704 bytes; crc 48653) Testing X connection... OK Testing Y connection... OK Testing Z connection... OK Testing E connection... OK So my question is...this isnt normal right? This same question has been brought up here before: https://www.forum.makertech3d.com/forum/assembly-1/tmc-connection-error?origin=auto_suggest 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.
