Z height with permanent printing plates

Recommended Posts

hello .... can you install a function where you can set the z height in the menu a bit higher? especially for permanent printing plates it would be interesting so you could use the automatic active bedivelierung again .... had such a function on sigma ... you have the bed automatically leveled and then you could put it a little higher in the menu, this was synonymous then saved as a new z worth ....

Hi, ok I think your solution is to use a Z-offset command. Printing uses absolute positioning and the z-offset command changes the physical position where the 0 absolute position is located. I think you are asking to bring your bed a bit closer to the nozzle when you say "a bit higher" ?


You need to put your G92 z-offset command into your Start G-code. You will find your Start G-code in the printer settings. Go to Menu item Settings, then select Printer, then select Manage Printers. A list of printers will be displayed in a dialogue box, select your printer from the list displayed and then select the "Machine Settings" tab on the right-hand side.


You will then get a dialogue box showing details of your printer and on the left hand side a box called Start g-code. This is where you enter your command. You need to do your positioning in relative mode, i.e. relative to the z axis position when this command is processed. So


G91              ;set relative positioning

G92 Z+0.050       ;set z-offset to move bed closer to nozzle by 50 microns

G90              ;return to absolute positioning


This assumes you want the move to be 50 microns


Oh, if the dialogue box already has g-code in the Start gcode box then best if you post it here, before doing anything. Especially if it has G90,G91 or G92 codes


IMPORTANT: This is very important. I think G92 Z0.050 moves the bed away from the nozzle and G92 Z+0.050 moves the bed towards the nozzle, but I am not certain. I have only used the G92 command withabsolute positioning and the Reprap paper on commands I am looking at, does not comment on negative vs. positive positioning when using relative positioned commands.


Hopefully someone on the Forum can give a definitive answer. 


Anyway I will advise you to test this. 

I assume your gap between the bed and nozzle is 0.1mm and so I chose 0.050mm as being midway. 

After the G90 command enter the command for an emergency stop -  M112

This works with most firmwares but not Sprinter; I do not know what firmware you have.


Before running the g-code, slide a piece paper between the bed and the nozzle, you should feel some slight friction.

Run the gcode and check again; you should feel an increased friction; if you feel nothing then the codes are the wrong away around - the bed has moved away from the nozzle.


And finally change the 0.050 measurement to what you want.

    • "Back To The Future" using Generative Design & Investment Casting
      Designing for light-weight parts is becoming more important, and I’m a firm believer in the need to produce lighter weight, less over-engineered parts for the future. This is for sustainability reasons because we need to be using less raw materials and, in things like transportation, it impacts the energy usage of the product during it’s service life.
