Ghosting solution

Hi prusa user 🙂

I own prusa mini for 1 and half year. I work very well for long period. Usually I just lubricant it every month. Just yesterday I recognize my print piece have ghosting problem appear. This are my problems.

1. What procedure I need to precise identify the problem of this ghosting?
2. I found prusa tension meter but it need to print with petg which i do not have. Can I use a free replica model and print with PLA+
3. Other suggestion to solve this ghosting.

thank you in advance 🙂

ps. my print piece in attachment

Best Answer by bobstro:

Ghosting is normally a rippling effect along vertical surfaces created as the X or Y axis moves. Yours looks like the 1st layer which is printed horizontally. Such rippling on the underside of the 1st layer is typically created by being too close to the bed (Live-Z too low). Verify that is the bottom of your print.

If you have not already done so, try Jeff Jordan's "Life Adjust" procedure for calibrating your Live-Z setting. It is much easier to use and understand than the onboard routine and much easier to make mid-print adjustments accurately with. In general, start high (less negative) and work lower (more negative) in large increments (e.g. 0.1mm) until the filament starts to stick on its own. When you've got your Live-Z setting adjusted properly, you should be able to gently rub the extruded lines on the PEI surface without dislodging them. Then start lowering (more negative) the level until there are no gaps between layers. You should not be able to peel the lines apart after printing, but the top should be regular.

Looks more like 1st layer issues
