STACKER 500KS USER GUIDE 42
8. Calibration of X/Y/Z Motion System.
Your new STACKER 3D printer is fully calibrated at the factory. However, the shipping process can
throw off tolerances and so too can environmental conditions like hot and cold temperatures, heavy
humidity, etc. Also, as your 3D printer goes through the breakin process things like belt and
bearing tension may require slight adjustments from time to time.
There are four basic calibration/adjustment areas associated with your X/Y/Z Motion System:
1. Bearing Clearance/Fit
2. Belt Tension
3. X/Y Gantry Squareness
4. X/Y/Z Motor Steps/MM
Please take each one of these calibration steps in order. For example, it’s important to get your
gantry square and belts tensioned properly BEFORE you change the motor steps in your EEPROM,
as changes to either of these two things will have an obvious impact on your step settings.
Step 1. Bearing Clearance/Fit.
To adjust the bearing clearance on the Y and Z axis, use a 2.5mm hex wrench, as shown. Be VERY
careful not to overtighten the bearings. If your bearings are too tight, simply loosen these screws.
Only do this step if you can feel a lot of slop.
To adjust the bearing clearance on the print heads (X axis), begin by removing the hot end heater
block with the 1.5mm hex wrench. Then, loosen these two screws, as shown in the photo below.
