I got my printers belts changed
Now it has started fixing the layers
I’ve tried tightening and loosening
x and y axis belts all it helped was that before it shifted on the second layer now it shifts after 30 minutes of printing
So if the print is less thn 30’or around 20 minutes it won’t shift the layer
Please help what to do
Thanx
Did you tighten the belts enough? When you “pluck” them it should make a sound similar to the low end note on bass guitar.
Are the belts TOO tight? This can cause problems too.
If the gears your belts go on are “open”, that is the belt could move off if overtightened, tighten to just below where the belts hop off. If you strum the belts in a repeatable way with a guitar tuning app, you can get to an optimal tightness.
I’m trying to get a more reproducible method of correctly tightening them. Most places I see just say they should be “tight enough” or, as @Adam_Steinmark above, they should strum like a low bass note. Very imprecise.
@Lars_Clausen I don’t really understand how what I said what imprecise. The belt tension doesn’t matter so significantly that if it’s slightly off the accuracy will be different, if that were true you’d have to adjust the belts after every print or mid print for longer prints. Tighten your belts and pluck it, does it sound like a low bass note? If it’s too high pitch you over tightened, if it’s too low or doesn’t really make a sound it’s either hitting something which could cause an issue or it’s too loose.
I thought I had mine strummed. I plucked them and they sounded bassy to me. Once I tightened them as much as they could handle, my print quality increased a lot. So either the definition is too loose or I don’t know what a low end bass note sounds like. In either case, a more specific instruction would have helped me.
I’ve never worked with a machine where they recommend a very specific belt tension…
@Nathan_Walkner I guess Lulzbot, Ultimaker, Prusa, Printrbot, Markforged, and Voxel8 don’t make “real” machines…
Oh well yeah but I figured we were just talking printers since @David_Sherwood said a nicely engineerined kit should tell you
