Hello,

As some of you may know I recently built an Original Rostock Delta machine and I finally got the levelling sorted out but the quality of the prints is quite bad.

I think It's because of the printed arms I am using which is creating a lot of vibration/backlash.

My hotend is an E3D clone, I'm also thinking it could be the source of the problem, well one of them anyway.

I've attached images to this post.

That was printed at 0.2 layer height at 50mm/s.
.
Thanks.

When you say vibration/backlash do you mean the motors sound like they're skipping?

Thanks for responding.

I mean that the arms have a lot of flex to them and they shake a lot during printing, effector too.

Which slicer program are you using?
What material?
What temperature is the hot end?
Heated bed? If so, what temperature?
What speed?
What are your retraction settings?
Have you calibrated the extruder?

Have you tried slowing the speeds down until the arms are stable?

I'd recommend printing some of the calibration objects available on thingiverse so you can get a better idea of what's causing the failure.

Cura and Simplify3D
PLA
190-210c
No heat bed
50mm/s
30mm/s 0.4 distance (I've tinkered with this a lot)
Yes.

I haven't tried slowing it down but I will.

I'll do that.

Cheers

I just bit the bullet and ordered carbon arms. I will do testing once those arrive and are installed.

I tried printing something really slowly and the quality improved quite a bit. I will upload a pic tomorrow.
