I have a strange situation it seems. I've got my 300 Trident printing quite well but have been wrestling with Skew. Using Vector3D's Califlower, my pre-correction skew is 0.23 degrees. I've printed multiple post correction califlowers and I get a skew of .01 to 0.02 degrees. Gantry seems properly racked. Belts seems to be good, they ring at the same pitch. I've checked to make sure screws are snug, including on the frame. I've checked full_steps_per_rotation for all the motors.
Trouble is, even though the califlowers show low skew, printing actual parts shows more and I can't figure out why. The center of the items (this is close to where I install screws) seems good, it's getting further out where there seems to be issues. I've done both where I've printed multiple parts at the same time and one by one, but still seems to have significant skew.
Starting to wonder if somehow my calipers have become inaccurate. I've had excellent results with the Califlower for my 2.4 and V0 for both skew and part shrinkage. To me it almost seems like my linear movements might not be linear. Or perhaps the shrinkage isn't being calculated right?
Thinking of trying a different skew model just to see what I end up with but given I've nailed skew with just 1-2 go 'rounds using Cali on my other printers, it feels like something with the printer I'm just not seeing (even though my post skew cali test prints seem quite accurate).
Any thoughts or suggestions?
