Today something strange happened.
I was weaving, weaving, weaving... when suddenly the pick count got all wonky. A few tight picks, then the advance advanced more and more.
I had to fiddle for mear to half-a-meter before I was back to (approximately) the same pick count I had before. As there are several pictures, I posted a more detailed story on my blog - here.
Some questions: when you adjust the a-a arm - how long does it usually take before it shows in the fabric? Can the warp beam brake be part of the problem? How?
Any suggestions as to what happened? (And - how do I avoid it in the future...?)
