I am new to 3D printing - have just built my first printer - a Prusa i3.
I have calibrated it to a few decimal places and done a few test prints - a 10x10x10 cube measured 9.93mm on my digital callipers.
But, for my first ‘real’ print, I seem to be having a problem and I’m not sure which area it lies:
When I print (using PLA), my print starts out fine, but as it continues, the print head drags on the print, eventually hitting it hard enough to miss steps and thus, screw up.
As it seems to get progressively worse, is it more likely to be calibration or have I got my steps per mm too far out (they are within a couple of decimal points - so 100mm = 99.25mm)?
