Dear octoprint community,
I’ve recently upgraded my Ender 3 Pro with the SKR 1.1.5 board with a BL Touch.
Sadly since this upgrade I cannot print reliably with Octoprint any more. I’m seeing errors like:
Send: N1047 G1 F2250 X98.922 Y141.349 E650.56694 10
Send: N1048 G0 F11250 X99.488 Y141.349 122
Recv: Error:checksum mismatch, Last Line: 1047
Recv: Resend: 1048
Before the upgrade i had occasional blobs from the printer microstopping (discussed in another thread here, but at least prints were finishing.
I’ve done the usual, reinstall the Pi, change the USB cable, change the powersupply (3000 mah). I don’t see undervoltage issues.
I've also increased serial buffer from 4 (standard) to 16, but it did not cure the issue. SD card printing works great all the time, only Octoprint causes errors which ultimately make the printer reboot.
I’ve uploaded serial log (error f.e. line 2448) & octoprint logs (error f.e. line 1166) here: Octoprint logs
I've also worked through the other posts here and tried all the fixes in there.
Here is my configuration:
Printer: Ender 3 Pro
Board: Creality Silent 1.1.5
Firmware: Marlin 1.1.9
Serial Buffer: 16
Controller: Rasberry Pi3b+
Puglins: Bed Visualizer
Usb cables: various
Storage: USB HDD
Power supply: 3.000 mAh
I’m honestly a bit lost what to try next to get Octoprint stable again as it is a great too.
Thank you very much for your help!
