Debugging Compu-dobby I

Hi weavers

I've finally gotten a computer and software to talk to my AVL Compu-dobby I on a 16-shaft production loom. I've got a sampling warp on and was proceeding to weave just a straight threaded tabby and have found that only some of the shafts life each time. When I look at the dobby box it looks like some of the wires aren't clicking into place like the others. Has anyone else had this problem and how did you fix it?

I'm feeling rather depressed about it all at the moment, it's taken me several weeks to get this far setting it all up and I had fully expected to weave off that sample warp today and get into some real weaving *sigh*

's ok, I figured it out. Turns out it was all the first half of the shafts not lifting, the problem was that the dobby box needed to move backwards towards there loom a couple of millimeters.

If you are not a member of the Yahoo group WeaveTech it's where many AVL owners hang out.  There are some great trouble shooting files on the group's website, too.

Thanks Laura, I'll join that group now and see if I can debug my other issues ;)

Hello all,

I've been hanging back since I first got this vintage (1980s - manual converted to compu- in early 90s) 16-shaft, 40" FDL last February, trying various suggestions given here and on WeaveTech for wayward shafts. My problem is that shafts 15 and 16 are very unpredictable - rise when they shouldn't or don't rise when they should - with the result that I have to watch every lift to check (gives new meaning to "slow cloth"). What seems odd to me is that as soon as I hit "unweave," the correct lift is made every time! Ditto on the way back when I cancel "unweave." I've been in touch with the AVL and software (Fiberworks) folks, but we can't seem to resolve this.

My latest attempt was to put on a 15-shaft warp, but shaft 15 is still wayward--sometimes. It's the unpredictability of it all that is truly frustrating. At least the pattern on this one was only 8 picks long, so I pretty much memorized the lifts and didn't have to keep looking at the computer screen to see whether the shafts called for were actually lifting. Anyone else out there with this problem? Suggestions welcome!!
