I’ve only had my A1 for a week or two, and I’m already experiencing the printer scratching my prints and sometimes the filament does not stick to the build plate. How can I fix this?
By cleaning the plate with water and soap and not touching the printing surface with your fingers.
Was having this issue for a week now, with multiple failed prints on the same model; but all of these changes 100% fixed the issue. I’ve read dozens of forums and reddit posts the last few days and this was the only thing that gave me results. Much appreciated!

i also wound up here with the same issue. i purchased both an a1 and an a1m in december both are dragging on the infil during travel on every print. i have been trying to figure this issue out for 2 months now. i am testing the suggested settings on my a1 as i type this.

i have printed multiple models with these new settings and i can confirm that the dragging on infill issue is gone. even with grid infill and .6 z hop it works perfectly fine. i do believe the main culprit was reduce retractions on infill that was causing it to skip z hops.

In the settings, there is an option called
“Reduce Retraction in Infill” — and in my case, it was enabled.
When this setting is on, the printer doesn’t perform retraction during infill moves.
As a result, the nozzle drags over the filament that’s already been laid down, which can cause rubbing, surface defects, or even filament grinding.
After disabling this option, the problem was completely resolved.
The nozzle now moves smoothly over the infill without dragging, and overall print quality significantly improved.
Make sure Z-hop is enabled, especially if you’re using fuzzy skin or have delicate outer walls — this helps avoid any potential nozzle collisions.
Thanks for bringing this up
This helps only in single color prints. But with multicolor prints, after every layer change when printhead moves to the purge tower, there is no z hop and it hits everything through it’s straight path.
