Geoff's Mini Kossel Adventure

[nka]

Altrougt I love the Delta design. I'll be moving to the CoreXY. Just becose I dont have the time to tune it right... and I'll wish to have something a little bigger than 170mm. And it should be more solid (less chance of having to recalibrate when moving it.

Can you clarify something for me please?

The Core X/Y.

Is that basically what my flashforge is? Z moves up down, the carriage moves X/Y?

I agree strongly on the moving the printer comment, I can put my flashforge on its SIDE and it will still print (I am not joking... it will print at 90 degrees and the steppers are strong enough to hold it all ) I flipped it up to check underneath when it was printing once, I left it standing on its side and the print was not affected at all, should video it actually!)

The delta, if you pick it up the frame can flex and thats bad as you know... luckily the autolevel does do a good job and compensates somewhat.

Yes, exactly. Everything is printed from top to bottom (Z Axis bed is moving to the bottom). XY are drived with 2 stepper using crossbelt and three carriage (2 for Y, 1 for X).

www.corexy.com for the "XY part", just need to add the "Z".

Ok I got it now, I think that would be like the Mantaki I saw where the head is on an X and Y slider with cross beams coming out all 4 sides of the head.

I am not sure now what to build next lol... I am so happy with the Delta and the fact it not only doesnt wobble, but can print when something isnt even stuck to the build plate (literally.. when I say mine has no backlash, I don't know whether my belts are just super tight or what but man... i have never seen a printer work so well when a print is failing.

I printed a 10cm tall bust, I heard a cracking noise about halfway, and I knew the crappy first layer I saw go down came off, it was my fault for not restarting the job when I saw it, but I saw to hell with it, print away

... but it was a 4 hour print and I was 2 hours in... oh man what do I do??

I paused the job, positioned the bust back to where it was supposed to be (which was easy to see thanks to the brim) and resumed printing, I held my breath... HOLY CRAP.. it worked. It printed 2 hours worth of 0.1mm printing without so much as knocking the model more than 0.5mm. A couple of small step lines - but for a job that was not stuck to the plate, i have to say for zero wobble at all, kossel seems to be the winner there.
