This machine does not have a probe, right? In that case there's no z-offset.

yes no probe and does ot make sense install on ramps? Z offset would be convinient anyway - I must use babystep each print 😭

Sure you could use some kind of probe on a ramps board.

#

And you could apply a semi-permanent offset to your Z by homing, babystepping to what you want to be (0,0,0), then running M428 followed by M500 . (https://marlinfw.org/docs/gcode/M428.html)

Marlin Firmware
Home Offsets Here

Use M428 to set a persistent offset to the native home position and coordinate space by assigning the current position as the native home position. See the example below.

ok so I can add probe of your suggestion

#

I have only one or two cables left to use

You could re-use the connector for the z-endstop. My only experience with probes is with inductive ones, but that requires a metal print surface (can be coated). Some kind of *touch sensor could work, but you've got to ask around for a recommendation on which one.

my idea is to put 18 mm chipboard and PET 2mm to print cold bed

#

alu is 25mm below so for sensor too far

#

I could remove chipboard and silicone

I need babystep to be remembered
