I have E3 V3 SE and tried CP-6.0. When I export gcode to file and then to print, the heat does not turn on and if I have the bed heated up, it gets turned off.
As a side note. I accepted defaults for first print and my bed got obliterated. The default settings of 0.08 for first layer destroyed me PEI coated bed so quickly I didn’t realize what was happening.
Sounds like your z-offset is totally wrong and needs adjusting up.
I can’t get my V3SE+sonic pad to work with CP6 at all. I’ve stuck with Orca.
Additionally, at the end of the print it just sat there and subsequently melted into the print and stayed hot until forced the extruder up and manually shut down the heat.
Sorry for the time folks but I’m done with this software and returning to Cura.
Give Orca a bash, its what CP6 should have been but failed.
