I have an A350 and am quite new to this thing. I’ve been trying to tinker with various settings so the prints come out nicer, because they theres always some kinda junk going on someplace.
Anyhow…
This happened to a print last night, but I thought it was just because it was a real flimsy print (it was a clockwork spring) and just threw it away
So I am printing right now a simple 3d model of a charmander (for a contest prize) and for some reason, the hand is not attached to the body.
you can see that it has the arm above it, but its shifted out of place (on the support) instead.
Is something wrong with my linear modules or something?
Typically a lateral shift would mean missed steps somewhere due to the stepper motor driver overheating, which can happen with these machines (there’s a silicone cooling pad on them that on some people’s linear modules was not making good contact or fell off). But in this case the lateral shift doesn’t look like it goes thru the entire model being printed, only that arm.
That looks more to me lie the floating arm (which would have been an independent ‘branch’ before the layers got higher) maybe sagged or got ‘bumped’ while it was soft by the head during a travel move. I just don’t see clear evidence of the same shift at all over that entire layer. Then again I also don’t see ‘sagging’ in the next layers above it which would no longer have had support…so maybe as the part was being printed further up due to cooling it just fractured down there and the part you indicate slowly sagged after that.
It’s a weird case, that’s for sure. Looks like you don’t have an enclosure. Make sure there’s no ceiling fan or AC vent cooling the part as it’s printing and maybe rig a partial enclosure (cardboard box or something) to try and keep heat in around the part.
You can try and re-load the g-code file (if you saved it on the memory stick) back to Luban, or to another Slicer to look at it, make sure there’s not just a digital bug in the code itself.
Thanks for the suggestions. I do have an enclosure but i have not assembled it yet - i was eager to play.
I used Cura to slice it after trying the Luban many times, and I must say I much prefer the Cura options, although I don’t quite understand many of them, it gives you descriptions on everything and there are so many little adjustments to make.
I abandonded that slice and tried a few other variants on it and I finally got one i deem acceptable quality, so yes it may be just a random fluke for some reason.
I thought maybe it got bumped so I had added z-hop to it.
