Start print

How do I sort out startup print. It starts to extrude in the Center then moves to bottom right. I want it as before. Extrudes at bottom right. Home position.

If you want people to help you, you have to give a minimum of information. Which printer, which version of ADVi3++, what are you doing, what means “before”, etc.

It’s a cocoon plus with the latest advi3++ V 4.0.6.


By before…l I mean… the printer started extruding from bottom right, now after the firmware update it starts from the Center, extrudes the filament then creeps to bottom right before it starts printing

This looks like a problem in your startup script. Can you post it here? And what kind of slicer do you use?

I use cocoon cura. This issue only started after the firmware update , like I mentioned before

Please post your startup script.

Your startup code contains nothing to move the head on the corner. That’s why it stays where it is (in the middle). It is better to use the gcode I recommend in the User Manual.

Like I said… this only started after v4.0.6 update. My slicer has not been touched. Got nothing to do with the start code. How come was working well before the update.

And which version do you had before? And do you have a BLTouch?

i have a bl touch and i had ver 2. something prior.

With version 4 and a BLTouch, the safe home is in the middle of the bed. You have to change your startup script to move the head where you want.

You just have to move the line

G1 X20 Y0 F140 E30

higher. For example after G28 Z0. But as I said, you should use the startup script I recommend.

What startup script?
