got it. Went to yet a third set, the white from the crimp kit (once again ever so slightly different that the white ferrules in the Duet kit... Metric vs imperial?). But even those wouldn't fit all the way in, so I did a second crimp of just the very tip, which crunched the end to the point where i could remove that little bit, an which point I could force it into the terminal.
Am I the only one w ferrule issues, or did some just skip them (like I almost did)?
Well the hardware is about done (just need to extend one of the FSR cables... they are too short to reach across the bed, any issues if one of them is longer than the other two?), then on to the software setup, which I am not really looking forward to, as I expect there will be issues based on my limited knowledge of such things.
This won't be my last plea for help...
