When smooth curve cuts have “wiggles” or “vibrations” I think of mechanical problems. In the past, these problems can be solved by changing configurations (speeds, accelerations, etc.) or making mechanical adjustments (upgrade steppers, oil bearings, etc.) However, this “wiggles” problem has us stumped.
Compare the design below to the cut below.
Note the wiggly lines that occur periodically in the cut.
Those cut lines are not a single pass but two identically flawed passes.
(If the problem was mechanical then it wouldn’t present exactly the same way twice.)
Does anybody have any idea what the problem could be?
For background, this is just an image that was traced using LB.
Also, we’ve lowered both speeds and accelerations but to no affect.
For the record, we run RuiDa controllers (6442G) and currently LightBurn 0.9.21.
