Up 300 bed raises and lowers between printing raft layers - is this normal?


I’ve had my UP300 for a week or so and I’ve only just noticed this behaviour:

I’m printing in ABS on perfboard using rafts.

I’ve just recently noticed that the printer prints the first layer of the raft, then the bed is lowered and raised, the second layer of the raft is printed, the bed lowers and raises again and then the print continues.

Is this behaviour normal? I didn’t notice it initially because I typically walk away as soon as see the filament is adhering well.

My previous UP printer (the first model) did not do this and I’m not sure this is normal for the UP300 or some potential new issue that has just begun.

The prints themselves are coming out perfectly.

Any feedback is appreciated.


For Raft, this is normal.
