Description

THE TEST DISC

The Bambu Printers do not have an easy Z-Offset baby steping interface. If you notice your prints do not have a perfectly smooth first/bottom layer (you see layer lines), you can change the z-offset in Bambu Studio to give it more squish.

Goto to Printer Settings | Machine G-code |Machine start G-code. You will need to scroll down until you find the section for z-offset on textured build plate. Change the value one at a time (from the default -0.04 to -0.05 etc.) and retest with a Test Disc. change this to a higher negitive number brings the bed closer to the nozzle. WARNING if you change this number incorrectly, you could cause damage to your bed, nozzle or other parts. Do this at your own risk!

 

BAMBU X1C Example Above: I started at the default z-offset = -0.04, using this calibration disc, my z-offset ended up at -0.10 (perfect smooth 1st. Layer, if it was to close, backoff to -0.09). Your Z-offset results may be different. This process can also be done for other plates as well, you notice I also changed the “Cool Plate”.

 

Can be found in the middle of Machine gcode - Example:

;========== For Textured PEI Plate, Cool Plate =========================================
;curr_bed_type={curr_bed_type}
{if curr_bed_type=="Textured PEI Plate"}
G29.1 Z{-0.07} ; <-------for Textured PEI Plate
{endif}
{if curr_bed_type=="High Temp Plate"}
G29.1 Z{-0.01} ; <-------for High Temp Smooth Plate
{endif}
{if curr_bed_type=="Cool Plate/PLA Plate"}
G29.1 Z{-0.01} ; <-------for Cool Plate
{endif}
{if curr_bed_type=="Engineering Plate"}
G29.1 Z{-0.02} ; <-------for Engineering Plate
{endif}
 

❤ Dont forget to Like and post your results! ❤

 

UPDATE: By request, I've added the Z-disc “collectors cup” save those smooth disc's like trophy swatches.

Sorry K2, that’s wasn’t supposed to be. I’ll rerun and take a picture and edit review.

Test disc, did what I needed it to do. Use it for calibrations and testing things.

Perfect for making sure my z-offset is fine, my printbed is clean, my printhead is good, and my desk doesn't have rings from my drinks. Start with the default print profile, adjust as needed. (I now use this print to adjust my elephant's foot calabration.)
