what is the best way to clean the a1 parts, ams hub and surrounding getting a bit dirty, thank you
A little isopropyl on a clean cloth is probbaly OK. Just don’t pour it on the printer directly.
For the plastic body and AMS hub, a microfibre cloth lightly dampened with water or a little isopropyl alcohol does the job without harming the finish. Avoid harsh solvents. For dust in crevices, a soft brush or a quick blast of compressed air works well. Just power it down first and keep moisture away from the electronics and rails. For the rails, wipe old grease and re-lube rather than just cleaning.
