Turning of the SSR heated bed immediately kicks the printed part

Are you using Bang Bang heater control or PID
A long time ago i was using BANG BANG and i put a indicator on the platform and i could see movment in the platform of up to .2mm. I changed to PID and that variation went away..you can use PID with SSR without a problem.
Also if i were you i would use a seperate power supply for the DUET controller and one for the bed heater that should control your 24vdc variations. (Personally i would use mains to power a bed heater but that means purchasing a new heater)
One other thing that i noticed was the way you are pulling the filament off the spool. With that arrangement you are going to be twisting the filament. This may cause issues with the extruder. -

@danzaywer I did it. Powered the board with adjustable power supply to see the current it draws. 0.18A at idle and 1.80A when hotend is on.
Ac outlet 230volt stable. PSU output 24.2volt stable. Board power input connector 24.0 v stable.@percar It is in a PiD mode. I'm using two PSU. The 24V psu is for the board, 12V psu is for leds and 12v fans around enclosure. Filament spool made by a turntable. It is a free spinning bearing.
@rjenkinsgb I understood what you mean. I tried it. Nothing seem works really right now.
I don't know if this macro shows a layer height change or over extruded layer? I think layer height is different than others.
Anyway I'm tired. Don't shut off the heater bed and problem is solved.
