I need some technical advice. A few months ago, wide horizontal ribs started appearing on my prints along with vibration-like patterns on the sides. -See pictures attached-
I've been tinkering with the settings on a basic level (acceleration, for example), even if I'm not entirely familiar with the whole set of G-codes for the Reprap/Marlin system, so I might have screwed something up. Now I'm stuck...
The code was generated in Cura with 20mm/s print speed, 0.15mm layer height and 95% flow rate to make the flaw stick out more.
XY acceleration is 1000mm/sˇ2 , Z is 250mm/sˇ2
"You mean you had such waves? I'll definitely try this then."
Could very well be worth looking over, any case, it's on more thing that you can rule out.
Here is a picture of the test block that was on the printer from the factory sitting next to a white test part I printed a few days ago. You can see the horizontal bands in both parts so the issue was there from day one. (I knew there would be a reason to keep that block :-)
The printer was a year old last October.
Obviously it would be better if the parts didn't have this artifact but fixing it would likely be difficult and expensive. I saw a Makerbot printing some parts in a store the other day and the surface finish on those parts were not impressive at all.
I'm a little spoiled of course since at work I get all my parts printed on a fancy polyjet printer. Those parts are perfect with a tolerance of +/- .001". Of course that printer costs about three times the cost of my car!
Just thought of something that can be worth checking. How is the tension of the X/Y/Z axis belts? Also, what about the linear bearings, are they running smooth?
I just realized that on our old printer, we had similar problems with irregular horizontal lines, in this case the printer had been in action for a while, without any actual maintenance.
We went over and tensioned the belts, lubed the bearings and calibrated, since then we haven't seen this issue.
Maybe worth checkin in to ?
Done... different material (ABS instead of PLA), an object twice the size of the previous one. Same 5mm ribs on sides 2 and 4, semingly fitting into each other. That looks like the wobble you mentioned.
-Does anybody know a way to correct this?
