I have upgraded my CR10 to the V4 motherboard.

I have BLTouch bed leveling and run octoprint.

Issue 1. I cannot get it to run bed leveling with the firmware I have.

2. when i run octoprint i get the following:

Warning: Firmware Broken

Your printer's firmware is known to have a broken implementation of the communication protocol. This may cause print failures or other annoyances. You'll need to take additional steps for OctoPrint to fully work with it.

Can anyone help with the right firmware to correct these issue and operate the bed leveling?

Also, does connecting octoprint to V4 require a special cable? (the early motherboard I had would only work with the genuine cable)
