The bed is a real pain in the Kossel.

What extruders design do you use ?

....The biggest problem is that is got difficulties to unwind the spool and you loose parts. Indeed, in PLA, I lost 1 part on 3 due to unwinding problems....

About the PETG, in my own words 'it is pretty much experimental'.
However, while the tuning is more delicate than for PLA, it will constitute a good alternative to ABS at cost ZERO, because it doesn't need a heating bed. And :
1/ It is easier to extrude than PLA, so I never had any extruder skip with it
2/ The filament is more slippery and I never had any unwinding problem (with my piano wire filament guide)
I got some other problems and it need survey, but I don't loose as many parts as with PLA.

As there is now a separate subforum for the Fisher at [forums.reprap.org], I suggest we close this thread. PRZ, you may wish to use your experience to assist another user who has posted a couple of questions there.

Dc42 the Kossel is very fast but it feels like any bump will let the print fail and the machine get out of calibration.
Interesting, I haven't had that problem. Perhaps you need a little more motor current?

True is that i have not co spidered any bed calibration and that the choice of a moothieboard did not help, I the end I might disassemble everything and get rind of the smoothie board.
4-point calibration is not hard to do manually, see section "Calibrating the endstop positions, delta radius and homed height" in [miscsolutions.wordpress.com]. Unfortunately, 4-point calibration was insufficient for my initial Kossel build because the towers were leaning slightly.
My Kossel extruder failed yesterday, so I am back to using the Ormerod as my only printer until I fix it. My Ormerod 1 works well enough, since I upgraded the bed support, Y belt clamps, X arm and IR sensor. I find VortyZA's spring loaded version of the Ormerod extruder drive works well and I'd like to adapt it for the Kossel, but unfortunately the files are not available in OpenScad format.

If you need, send the step files to me and i try to convert them. Or make an account for Autodesk fusion360 that should allow to import step files. It is an amazing software to design stuff and free for maker and hobbyists, while profs like me need to pay for it.

As response to OnShape (I think), autodesk has made Fusion360 Ultimate free for non commercial use including personal use or use for things not being sold. Not for 90 days, forever.
