Actual behavior: [What actually happens]

They don't.

Additional Information

Error in octoprint terminal:

Changing monitoring state from "Error: No more candidates to test, and no working port/baudrate combination detected." to "Offline (Error: No more candidates to test, and no working port/baudrate combination detected.)"

reverted to a previous release: Smith3D-E3V2-2.0.x.14-3x3.bin

everything works.

Which board are you using?

alexeyatbluescape commented 3 years ago

4.2.2 seems to be the right one

firmware-20210324-210154.bin.zip

Try this one. It is the latest compiled for a BLTouch (If you do not have a BLTouch do not use this)

I have been running it for 2 days and it has been flawless with respect to basic operation. Note: this is a user compiled version of the Smith3D GitHub repository i am not affiliated with Marlin or Smith3D. It works for me.

alexeyatbluescape commented 3 years ago

Thanks @tfaz099 I will tomorrow, once current print is done. I do have BLTouch, this should work. How are the configs across all version here are persisted? I with I could get one that I like and play with couple settings. Does yours have m600 command as well?

Note, this is probably not the best place to have a discussion, we can move it to the "discussions" but to finish this off... My start script (i am using Octoprint also and just recently started running off an SSD) any more discussion please start a thread in discussions and tag me)

I encountered the same problem. Octoprint can't connect to the printer with "Error: No more candidates to test, and no working port/baudrate combination detected." When connecting the printer to my PC it shows an unknown USB Serial connection in the device manager, with no compatible drivers being available.

I flashed the firmware from the marlin firmware service and it worked "fine", at least in regard of connecting to and controlling the printer. Other Issues with that firmware stemmed from the "nightly"-nature of those builds, not related to the problems I have with the Smith3D release. The user-compiled firmware provided in the post above doesn't seem to fix the problem either.

I have now solved the problem by using the Smith3D-E3V2-2.0.x.17-Fast-5x5-230x230-180321.bin and changing the detection baud rate in octoprint to 250000. Evering seems to be working, I'm running my first testprint right now.

tfaz099 commented 3 years ago

@philipphoh @alexeyatbluescape if you both have solved your issue, please close this issue so the actual developers have less on their plate. thank you.

alexeyatbluescape commented 3 years ago

@tfaz099 Can confirm, when changing the detection baud rate in octoprint to 250000, it works. Thanks @philipphoh for the hint! Not sure why auto was not detecting that rate before, now seems to be fine. Using Smith3D-E3V2-2.0.x.17-Fast-5x5-180321.bin
