Hello everybody
Recently I have a problem with Octoprint and BLTouch
( OctoPrint 1.5.3 - Python 2.7.13 - OctoPi 0.16.0) running on a Rpi 3 (system updated) and MarlinKimbra 4.3.9 on Radds 1.5, Original BLTouch
Error reported by printer
Your printer's firmware reported an error. Due to that OctoPrint will disconnect. Reported error: STOP called because of BLTouch error - restart with M999
This happens when the printer starts to move during G28.
If I reconnect octorpint (not reboot or restart ) and send the same print the error donesn't happen and all works fine to the end.
Sometimes the print goes at first attempt.
I was two times in front of my printer an I saw a strange behaviour
On G28 printer goes to X0 Y0 then moves to the center of my bed, rises Z (this is correct) and then it goes to error or sometimes the BlTouch pin start to move up/down many times and then goes to error..
It's a problem I am recently facing, may be after octoprint update, times ago it wasn't present and a friend of mine who has my same DIY printer, same exact firmware (we flash the same .hex file to both printers) and old octoprint don't ges to error state.
Here is my beginning Gcode (Ideamaker slicer) for a given piece
