I have many Pi4 with 4M and many TMC2208 and TMC2209 drivers. Is anyone using these items?Is there a video that I can watch to see how OpenScan is used and the results?I like what I see!Thank you!
Hey Alan, due to the current circumstances, shipping to the US is currently not really practicable (as shipping alone would cost 70-100USD). And it is not guaranteed when and how those shipments would be processed by DHL... I hope that the situation improves and that we could go back to normal soon(ish). Stay safe and positive,
Thank you for your reply. I guess there will be no shipping of board to US for a while? Hope you are safe!
Regards - Alan
The Pi 4 is working with the provided image. The only thing worth noting is, that the Ringlight-Connector has to be flipped 180° as the Pi 4 somehow swapped USB and Ethernet Positions... Concerning the TMC drivers, I think, that they won't work as the Pinout of the A4988 is a little bit different and I have connected the MS1-MS2-MS3 connectors on the PCBs. This might be a problem for the UART connections of the TMCs.
I am currently working on a video of the whole workflow, showing all the details of the interface. I hope to finish and upload this video within the next two weeks... You can see some results here: https://sketchfab.com/3d_TM/models and here: https://instagram.com/openscan.eu
