Weird Z movements

Recommended Posts

Hi,

I'll like someone else opinion. I just was printing some stuff and started to notice that the print was like 'crushed' down. I just printed something 40-50minutes ago and now was doing a larger print with some modifications. The think it's that after each 'z' movement I could hear a Z stepper sound, something I never heard before between layers and that sounds almost like if the Z was moving (I tryed looking very hard at the Z but didn't noticed anything).

My theory it's that the Heat it's doing something with the stepper. Mine it's a UMO+ (v2 board). And here are some photos of what the print was looking like.

This it's the heat that my thermal camera sees (and that's on the bottom of the printed, so that's how hot it's the bottom wood where the board it's.

The second print that failed was done with the same settings as the one before that went perfect.

But just in case here they are:

0.2 height, 65 speed, 50 for inner/outer shell. Infill 26%. PLA cheapblue, 210C. Also I print with 1.75mm filament (I could easily print at 200C) but I forgot to adjust that just because worked on the print before and this it's just a super easy flat think to print.

Should I start looking for some cooling for the lower bottom of my UMO+? I get that electronics get hot and here the room was at 28C so It's perfectly understandable if that's the problem. Maybe the heat it's making the Z motor failing ?

If anyone has the answer, thanks!

Steppers can handle tons of heat but the stepper drivers can't. Do you have the white board? It shouldn't need fan but 28C is a bit hot. I would tilt the UM by 45 degrees or even print on it's side (it prints fine even upside down). And put a desk fan blowing on the white circuit board to see if that helps.

    • "Back To The Future" using Generative Design & Investment Casting
      Designing for light-weight parts is becoming more important, and I’m a firm believer in the need to produce lighter weight, less over-engineered parts for the future. This is for sustainability reasons because we need to be using less raw materials and, in things like transportation, it impacts the energy usage of the product during it’s service life.
