Any idea on the lifespan of a nozzle. Basic PLA exclusively.

Also check the belt fitment to the belt clamp that rides on the X axis.

What are you printing on? Is the print surface moving around?

Any chance we can see a pic of the damage?

PLA.

I'm using just a plate, no PEI.

Using it with hairspray. Many successes, but at the same point, a high rate of failure.

Wondering that if the heat is measured at the HBP is it significantly different (lower) at the top of the MIC 6.

I'm hoping to have some discussion on bed heat and how it effects warping. Currently I am running into some problems with a particular model that likes to lift off the plate. The effect is increased when I print more than one of these items at a time, and therefore to me there is additional cooling ...

Here is a version I made. I gave up on the project, but perhaps this will save you some time.

I'm going to guess that this is due to firmware settings for acceleration and jerk. There were changes in the settings between these 2 machines firmware.

I would make sure that in S3D that you use the configuration wizard, and set the machine to the M2 Dual V4.

Sounds like there is some junk in the fan. It happens when stuff falls into the fan opening.
