Creality CR10 S Pro wont heat or start print

[msdosfx]

What is the problem?

Newly Installed Octoprint on Pi won't heat bed or print from uploaded g-code to CR10S Pro V2. Have printed from SD on this printer for over a year with no issue. Get the error: Your printer's firmware reported an error. Due to that OctoPrint will disconnect. Reported error: Heating failed, system stopped! Heater_ID: bed - Printer halted. kill() called!

What did you already try to solve it?

rebooted and retried. took out the SD card and retried. tried a different file. Tried to update firmware with the firmware updater plugin but doesn't seem to work with my board.

Have you tried running in safe mode?

Yes

Did running in safe mode solve the problem?

No

I assume the printer is powered on?
With some printers it can happen, that the LCD and the printers MCU are powered up by backpowering from the Pi's USB.

See more on this here:

Printers known to have backpowering issues

Printers that show backpowering issues try to draw their 5v power from devices connected via USB. In the case of a connected Raspberry Pi, that can cause undervoltage issues and thus negatively affect stability and performance - we've seen crashing Pis, vanishing WiFi and so on. There's a simple fix that involves putting electric tape or otherwise disconnecting the 5v line in your USB connector. Here's a list of printer models currently identified to exhibit this electrical design flaw in their…

Put tape on the 5V pin - Why and how

First of all this whole tutorial isn't a mandatory mod - you just need it if you run into issues (weird things are happening and you've already ruled out the more common suspects) or if the always running fan and illuminated display (even when the printer is turned off) disturbes you. I'm starting with the why part: If you connect a 3D printer via USB to your Raspberry Pi it can lead to all sorts of power related issues. Most of the time those issues occur only if you turn on your pi before …

Thank you so much! This community is so responsive and helpful. I hope I can contribute once I have learned more. For folks from the future who have the same issue as me, I had assumed that the fact that plugging the Pi into my CR 10S Pro V2 turned the machine on, that it functioned as a switch intermediary and turned on the power supply since I could see the LCD interface and heard it turn on. Not the case. First turn on your machine, then plug in the USB. I didn't have to do the tape trick, just turn on the machine, duh!

you should do the 5v tape mod. Having the printer pulling 5v off the pi even with the printer turned on can lead to problems.
