MakerFarm i3v first layer issues

[jheikkila54]

Hey all,

im having an issue with my printer making wavey lines on the first layer, it looks as if on side of the line sticks and the other side doesn't as much, picture attached. I have an auto bed leveler, printing abs natural 1.75 at 230, but 235 for first layer. Any thoughts?!

I can't quite make out what's going on in the pic, but a couple of bits of info from my recent "learnings" regarding ABS.

1. If you are running a hexagon HE with the stock MF cooling fan..., that can easily cause first layer and warping issues. If this is the case, you can start by simply reversing the fan so that it exhausts, i.e., draws air AWAY from the HE cooling fins. There are a couple of solutions for doing a nice job of this provided by clough42 and printbus. There is also a somewhat unsightly, but effective solution provided at:

2. What is your bed temp? These days, with a couple of exceptions, I use 110C continuously for ABS.

HTH.
