Hi guys. Can anyone tell me what needs to be changed to fix this? Thanks

It looks like your filament has moisture in it. Or dust.

:slight_smile: How far through printing your MPCNC?

+Peter van der Walt Could you please elaborate on what packing is and how acceleration fixes it? Thanks

+Peter van der Walt​ by packing you mean material build up? If that the case then it would mean I have to increase acceleration?

Well im getting overall great prints on this customer built COREXY but is always good trying to reach perfection

just need to lower the flow rate and higher the temperature of the filament. and maybe need to higher the retraction lenght…use “coasting at the end” will help.
