yeah i know, i just want to see if mine is similar with other or different, i set mine on xy axis around 0.7, below than that on the second layer or when it want to make solid infill the y axis make annoying noise

edit
the fastest shipment i received from china is 10days using free shipping also

is like a loud buzzing sound? If so yeah, i think thats undervoltage.

i dont know, if that sound appear, it like my whole frame is vibrate, so i change the vref from 0.5 to 0.7 and now my y axis stepper motor is a little bit hot from the x axis stepper motor, is it normal?

Vref control current flow. so yes, it is normal to get a little hotter. Although you need to monitor how hot it gets. 0.5 to 0.7 jump is quite big actually. thats almost an extra 0.6 amps. cant drop to like 0.6?

Just a question, if you drop from 0.5 to like 0.45 would it make any difference? Whole frame vibrating seems like a resonance issue.

0.5-0.4 not good for me
0-5-0.6 also not good, louder when it print solid infill

now on 0.7 something like that if quieter but the motor a little bit warm, can the belt tension cause the motor warm also cause my y axis belt is tight.

i set my x axis vref to 0.5 and it a lot quieter then the y axis, it almost like no sound coming from x axis when it moving.

shouldnt affect the motor too much. The bearing on those NEMA17 are rated much higher than breaking point of GT2 belts. Y axis is much heavier than X axis is it?

I think so, my y axis is acrylic->pcb->glass

owh movable bed design. Yeah alot higher mass and ur X axis is a bowden setup. It should be fine.

corexy box project, sudah lama stop sekarang masa untuk siapkan semua

yea movable bed, prusa i3

i think i already fix my banding issue or atleast 90% of it, by tighten the extruder screw it seem fix my problem lol i didnt remember how long i didnt tighten my extruder and i didnt use spring with the screw also

then now i will move to y axis, try to fix and find best vref for my setting

Cool, for me, i not yet figure out how i want my z axis for my new build

I have a prusa too. I dont like this design tho. Its too wobbly. I cant go above 80mm/s without it shaking too much

I never try 80mm/s on my printer, maybe i should try later and see how it go.

what frame do you use for your prusa? mine is acrylic and thanks god i didnt have so much problem with my frame.

aluminum. But without rear braces. like the original prusa i3.

much stronger but it lacks rigidity and the resonance frequency is quite low.

you cnc your frame? im searching to cut aluminum for my next printer bed

Until now i'm still not getting a good print. Initially thought the bed not even. But i try to turn it upside down still the same issue. Turn the x smooth rod 180 degree, same.
Finally found that is the weight of x carriage cause the head touch the bed at the center.
Going to change to bowden type extruder plus make a support for top lead screw for more stable print.

waterjet cut. cutting fee is around RM 200 for the whole frame. materials another RM 60

What is the thickness of the push rod on the X axis? Is it one of the hardened chrome ones or the bare steel ones?

Maybe getting a smaller stepper motor might help.

Edit:
Could also be due to the belt tension, bending the push rods.

CNC mills have this problem too solution. counterweight http://millhillsupplies.co.uk/wp-content/u.../CNCproj6b1.jpg

of course not as feasible in a 3d printer
