I have an interesting problem. i have a delta printer with a smoothieboard x5. arm radius and length have already been checked. if i move the head accross the bed in 10mm increments its fine, but if it move in 100mm steps then it moves in an arc kind of like powerlines or telephone lines hanging from poles if that makes sense.
Try to fine tune the arm radius again.
If you have probe maybe auto calibration should figure that out for you, if not then manual it is.

Someone else was having delta configuration issues. He probably has a different effector size after swapping his out though. I do not know smoothie firmware, but you might want to make sure that setting is correct too.
there is no effector size adjustment in smoothie config, just radius and length. mabey ill just try a fresh config file.
@Wolfmanjm ohhhh…i set it to 0 and was going to use mm segments and i set it to .3. so you can only use segments per second with deltas?
Okay. This explains it. The “radius” is actually a difference in two radius. It is the horizontal distance between the two ends of the diagonal arm (I imagine measured at the center of the joint on the end). Well, that was confusing.

it is the recommended way to do it yes. but if you had set mm_per_line_segment 0.3 it would also have worked ok.
it was…
but i just reset it to 100
you need to use one or the other not both.
yeah, i had the one at 0 and the other at .3. should i have commented the first one?
