Hi Heidi, I have an eight shaft Baby Wolf and sometimes have dealt with this issue myself, depending on the pattern and number of heddles per shaft etc. I definitely find that the BW has a very small sweet spot and keeping the warp tension just right and staying in the sweet spot really helps. Also, if there are many heddles on a shaft, using the treadle aids that Schacht provides or jazz bands (Lunatic Fringe) help keep shafts lowering well. Also, if it’s been awhile since you maintained the loom, clean well, removing any yarn dust from everywhere, and use silicon spray (recommended by Schacht) to squirt down the sides of the metal groove that holds each shaft. The shafts move up and down easily then, creating a nice clear shed. Oh and one more thing that has helped me. I typically use the slim Schacht 11” boat shuttle, but recently got a 13” one and find it skims along the race very nicely. Not sure why the length makes a difference but it doesn’t seem to ever pick up warp threads by mistake.
