z-hop during long prints

Recommended Posts

I have been experimenting with z-hop while printing some parts with vertical wires that often make that horrible combing noise when the print head moves across them. Imagine running your finger along the tines of a comb and you'll know what I mean.

I'm using a Ultimaker 2.

I'm wondering if anyone else has used z-hop much and whether I should be worried about the z-axis motor overheating or anything. I don't see a good reason for this to happen but I imagine that z-hop wasn't first in the mind of the engineers designing this printer.

The z motor is always on during print. Otherwise the z stage would drop. So there should be no difference wether the z motor moves or not. But if you are afraid of an overheated motor you may try to reduce its current in the UM2 menu. Just never go above the default setting by Ultimaker.
