Bug Description

<I am using MEGA_S_TMC_BLT_10_v1.3.0.hex on my Mega S with BL touch. Also octoprint. After print starts, printer randomly stops and looses connection with octoprint.
This is what I see in octoprint terminal window:
Send: N66 G1 X105.403 Y124.354 E5.11206*85 Recv: Error:checksum mismatch, Last Line: 65 [...] Communication timeout while printing, trying to trigger response from printer. Configure long running commands or increase communication timeout if that happens regularly on specific commands or long moves. [...] Recv: Error:Line Number is not Last Line Number+1, Last Line: 65 [...]>``
I have to power off/on printer. If I disconnect the connected camera on raspberry it seems to print next project ok.
I did reflash version 1.2.0. and it is working perfect with camera and octolapse. No problems with version 1.2.0.

Steps to Reproduce

  1. [First Step]
    Start print using octoprint and connected and enabled camera.
  2. [Second Step]
    Wait and see if it will manage to print or not.
  3. [and so on...]

Expected behavior: [Like version 1.2.0, but with added features of version 1.3.0. ;) ]

Actual behavior: [It randomly stops printing after loosing connection.]

Additional Information

Thank you for all your work so far!

You are the second person who reported the issue. But it's weird, because it works on 99% of all other machines with octoprint.

Can you give me some more information about your setup like

  • Octoprint Version
  • Raspberry Pi Version
  • All Installed Plugins
  • Comm speed

Did you try another power supply for the Pi and/or the camera?

The communication may be more "fragile" since there is a second serial interface in use. But technically it should not make any difference.

To test that, I built another version for you which disables the wifi-functionality completely. Please let me know if this fixes your issue.

I am testing this version and so far it seems to be perfect! I did print some calibration cubes and no problems with camera on and octolapse running.
Really appreciate your extra work!

Thank you so much for testing!
Would you mind to test another version linked below?
It's the same as 1.3.0 but with decreased wifi module frequency, so there is more room for the cpu to handle USB requests.

I need to find the sweet spot where both serial connections work reliable. If it's not possible at all, I'l deactivate Wifi for all USB/Octoprint users.

MEGA_S_TMC_BLT_10_v1.3.0-115k.hex.zip
MEGA_S_v1.3.0-115k.hex.zip

Please use it like before! Don't change anything in your configuration! Just use your printer connected to octorprint with 250.000 bps.

Hi Olli

I just tested the 115k version, but it is not working. I get the same error. I attach a screenshot from my octoprint.

erorr

But I canceled the print before I made the screenshot.

@Daddycool2708 : The Octoprint speed should be 250k as before. The 115k only applies to the Wifi Module, not usb

I did set it back to 250k but the result is the same. I get timeouts.

last one.. I promise!
If this doesn't work with Octoprint, I'll disable Wifi per default.

Hello! Sorry for my late response.
I went straight for MEGA_S_TMC_BLT_10_v1.3.0-250k.hex.zip and it is also not working for me.
Thank you for version 1.3.1!
