That's what I've been chasing, too. That first point visibly deflects the hotend, and it's been frustrating me. It's also somewhat intermittent. (my posts/rant were here: http://forum.seemecnc.com/viewtopic.php ... 974#p91442 )mhackney wrote:So to change the subject just a bit...
I've been running FSRs on all 7 of my delta printers. I only have 1 Rostock Max though, the others are mini Kossels and Kossel 250s. I get EXCELLENT calibration results on those smaller printers and acceptable results on the Max.
Has anyone else observed this?
I was chasing rigidity, and just picked up a set of Brian's aluminum arm mounts (which look awesome, by the way!) because the stock plastic arm mounts have never really set flat on the trick trucks, and I think that they can flex a little bit. I'll install those tonight, check my belts, and re-test. I've checked for loose belts, but I haven't made an effort to match them precisely. I'll let you know if it helps!
Another note, you can add another jumper to the JohnSL board to make it more sensitive. With my 6# aluminum bed, I found that it helps decrease the pressure needed to trigger the board, which on at least a placebo level has helped
