Checksum errors (OctoPrint 1.3.10 / OctoPi 0.15.1)

[jatmn]

I get checksum errors when using this plugin with OctoPrint 1.3.10 running on OctoPi 0.15.1

Octoprint will tell the printer (Ender 3) to Preheat the bed..
Once bed has reached correct temprature, I instantly get flooded with checksum errors.

This results in Octoprint becoming unresponsive (cant stop/cancel prints) and have to restart Octoprint.

As soon as I disable this plugin I no longer have these errors..

Just ran into this issue myself, found out what was causing it through https://www.reddit.com/r/ender3/comments/ajpl77/errorno_checksum_with_line_number_last_line_with/

Same issue with CR10. As @tg44 said on #13 , the colon in the command line is the problem (in oldest versions of Marlin) : MarlinFirmware/Marlin#1568

Hi Everyone.
I know that this issue is an old one, but just for anyone who finds it, I have fixed this bug after taking over maintenance of the plugin. See https://github.com/AlexVerrico/Octoprint-Display-ETA
Cheers,
