Most 3d printers control head position using stepper motors and end stops with no position feedback. The stepper motor does not actually know its location.
The printer's control system can only know the location of the head by keeping track of the relative number of steps the head has been moved by the stepper motors.
Homing moves all the axes in one ...
What is homing?
From the tag wiki homing we can read:
The process of determining the location of a 3D printer nozzle in
three dimension using a reference point (home location) is referred to
as "homing". Homing should occur before every print and involves
bringing the X, Y and Z-Axis motors to pre-defined limit locations
(usually these are ...
What are ABL and UBL?
ABL stands for Automatic Bed Leveling
UBL stands for Unified Bed Leveling
Level the bed?
A level bed (twisting knobs under the bed), or a surface that is exactly followed by the nozzle is a prime requisite for 3D printing. Without a proper bed setup (not only level, but also the initial nozzle to bed surface gap; usually the paper ...
Consider the environmental conditions where your printer is.
I have my printer in a garage, where the door is sometimes open, closed, or slightly ajar. This leads to gusts of wind, causing lifting and ruining multiple prints.
I surrounded the printer on three sides with walls made from the original packing foam, and my lifting problems have utterly vanished....
If you will be printing PLA, no, or at least not without active cooling of the chamber. PLA's glass transition temperature is sufficiently low that the ambient temperature matters a lot to whether layer N can cool enough before layer N+1 is laid, in order to have a firm surface to extrude against and bond to. This especially matters with overhangs and ...
