Retraction values and stringing?

Post by DITAmech01 »

Hello! I'm trying to eliminate a stringing problem. I'm running a MAX v2, MatterControl with Repetier 0.91, PLA @ 178 deg C. I'm trying to print the standard open pyramid.
Current settings:
    Retraction length on move: 7.5 mm
    Speed: 100 mm/s
    Z-lift: 0.5 mm
    Outside perimeter print speed: 10 mm/s
    Inside perimeter print speed: 20 mm/s
I've tried adjusting every possible setting, one at a time, and achieved absolutely no changes. I have noticed something odd - The retraction should be happening every time the hot end has to move from one place to another without printing anything, correct? Mine's not doing that.

Imagine that each of the four posts of the calibration pyramid is numbered 1 to 4. I can see that the EZstruder is retracting as the hot end moves between 1 and 2 and between 3 and 4, but it's not retracting between 2 and 3 or 4 and 1. So there's a stringing problem between 2 and 3 (big time) and between 4 and 1 (not as much, but still not good).

So if I should be seeing retraction for every non-printing move, and I'm not seeing that...what's going on?
