Nozzle stops for a bit after the 1st layer leaving a small b

[a4jp.com]

When I print the 1st layer of almost any model, it looks okay but at the end of the 1st layer the print nozzle stops on top of model for a short while leaving a blob of PLA just before the other layers start printing. Is this to do with the keep warm setting?

Is your first layer temp lower than the main print temp?

[a4jp.com]

No, I made the temp almost the same at the main temp to try and reduce the time it stops for now.

PLA

Main: 210
First Layer: 212
Keep-Warm: 210
Bed: 65

Any ideas would be great. I can't figure out why it stops after that 1st slow layer before it speeds up and prints beautifully.

[a4jp.com]

Here is a bit of the code when it stops after the 1st layer and waits for some reason.

Maybe it has something to do with this line: [INFO] RECV: echo:Active Extruder: 0

Code: Select all

No, that means that the first extruder is active (computers like to start counting from 0).
But what cought my eye was this:

There's a W parameter there that seems to count down until what seems like a stabilization period. That should be set on your printer firmware.
What printer and firmware is it?

[a4jp.com]

It's a Japanese printer: Scoovo X9H. It runs Marlin 1.0.0 and has a RAMBo board. I can't change the firmware yet but after I hope I can. Can you see any way around this countdown problem?

[a4jp.com]

I didn't get this problem in Slic3r so maybe there is something in Kisslicer that can help or some G-Code.

[Mikk36]

Well, if you know it works fine in Slic3r, you could replicate your settings there (first layer temp 2 degrees higher than the rest) and see what g-code comes out of it and then compare those two.

You propably also don't need those funky g-code commands during the extruder swap (first layer to second with temp change also counts as that): M542, M551 and M543. Marlin doesnt normally understand those.

[a4jp.com]

I commented out everything from

Printer G-Code > Select Extruder

and

Printer G-Code > Deselect Extruder

with semi-colons and maybe everything is good now.

Thank you very much for the advice Mikk36.
