Cleaning the bed table between the prints in printing queue
I am curious if it would be possible to add a possible "cleaning GCODE" for bed cleaning in between the prints.
I tried printing a small, simple cube one after another without manual cleaning, and it worked to remove the testing model from the bed, and it worked - the cube was small and simple to detach the previous model and yet the moves of the head before the printing of further model removed the cube itself.
But I get that it might not always work and that quick moves of the printing head might break the model.
So, I imagine a GCODE in which the printing head slowly moves across a cooled bed in a zigzag pattern to allow a model to be slowly pushed out. Possibly with some scraper attached to the head.
That might allow us to further continue with the printing queue without stops.
Did anyone try something like this?
RE: Cleaning the bed table between the prints in printing queue
I've seen people using custom gcode per part where the print head was lowered and it was knocking off the printed models.
This has some disadvantages such as it applies a force to the print head and it can effectively end in damaged/skewed/twisted print head or any parts - I believe 3d printers are not a a full blown CNC full metal devices that are adjusted for noticeable forces.
You should rather look as something like JobOx with replaceable beds.
See my GitHub and printables.com for some 3d stuff that you may like.

I've been able to add a simple bit of GCODE to the "End G-Code" portion of the filament tab that turns off the hotend and moves the nozzle away from the part, then simply waits for the bed to to cool down and then rams the part away using the X axis rods. I'm using it for mass production of some very tall and quite narrow parts so they release perfectly with very little force every time! 👍
I'm still looking for a better way to start the next print. Currently I first export the GCODE from slicer then open with notepad and loop the printing part which is a bit cumbersome and leads to huge file sizes.
