Hello
Could one of you more experienced fellas help me identify what’s causing this ripples? Yesterday was printing fine. My heated bed cable got caught and the bed vibrated since it couldn’t get to y stop. I checked all bolts. Find 1-2 where it needed a 1/4 turn more… But nothing mayor. I don’t think I missed anything else. Belts are tight.
Im right now taking bed off, making sure all bolts are nice and tight. Will print a test pattern soon to see…
It looks like there is shifting of Z layers. Help to know the type of printer or see a picture of it. not sure why Y bed block and motor skipping would cause Z axis issues. In pic it looks like the waves are on X and Y vertical faces alternatingly, which would be from the clockwise or counterclockwise oscillation around center from a bent lead screw. The offset will be more on Y and more on x depending on the angle of rotation of the Z screw. Linear rods should hold minor screw issues in check but it looks like this one is overcoming any frame and rod restraint and causing the nozzle to move in a circular pattern depending on Z screw rotation, so it changes regularly as the model gets taller. That is my assessment from one photo so it could be wrong
Actual printing settings not changed… All i did was take down the bed, go thru most bolts on the frame and X,Y axis… and the bed only had 1 bolt that was about 1/2 turn loose… the rest of bolts i found around, were like 1/4 turn or less. Only thing i did different from last time was not tighten the bed too much on springs.
