I would like to know if it is possible to calibrate the xyz axes to have perfect measurements. I made some 40mm test cubes but they didn’t come out perfect. How is it possible to calibrate the boards to have perfect measurements?
On older printers (Creality, Tronxy, Prusa and clones) this would be tweaking the e-steps of the motors. Can’t do that yet with BL.
Hi, You have to calibrate the filament, if you are not using Bambu Labs own. For me, I‘m do a ‚Pressure Advanced‘ and ‚Flow‘ calibration using the OrcaSlicer for each filament. This enhance the precision a lot.

Is it automatic in the sense that the slicer produces an already set design or do I have to take files to print and calibrate manually?
Download OrcaSlicer and run it. It has a menu “calibration”, which has some semi-automatic calibration methods for use. Here you can get an overview: Calibration · SoftFever/OrcaSlicer Wiki · GitHub
So as I read the preyious posts there is no way to calibrate the Z-axis on the X1Carbon?
My printer prints a little too low in height. I printed a 120mm high housing part and it is about a millimeter too small at a height of 119mm, so it does not fit the target device.
Out of curiosity I just checked mine using a 40x40 mm cube. Tried two configurations:
-
Generic PETG / Tex. PEI Plate / .6 nozzle / .3 layer / No Flow Calib. = 39.6 x 39.6 x 39.6 (X, Y, Z)
-
Bambu PC / Eng. Plate / .6 nozzle / .3 layer / Flow Calib. = 39.5 x 39.5 x 39.25 (X, Y, Z)
Not sure what the Z toleratnce should be but this is close to what I was getting on my MK3S.
Hi, I have also issue with not perfect measures. A 100 x 100 square comes out as 99.75 x 99.95. One could say it’s not a big difference, but it’s a slide in part, and when rotated by 90 deg it slides with resistance. I can make increase clearance, but it’s not the best workaround. It would be great if x/y could be calibrated like it’s possible with e-steps in old good Marlin. Any idea if it’s possible in A1?
Not possible for BBL printers. You have to scale your design to make it larger or smaller to compensate for that.
Just keep in mind, the nozzle is 0.4mm so the tolerence is about ± 0.2mm across X and Y. And all the plastics do shrink when cool down.
BTW, if you set your expectation that high, like tolerence less than 0.2mm, you should consider other method of manufacturing like CNC milling, it can achieve greater dimension accuracy than a 3D printer.

I use this for the Skew and the filament shrinkage works amazing and easy to use
Use this
Have you tried calibrating each filament for shrink?
