Support Touching Buildplate not printing fully

[Firepower]

I have a Cocoon Create/ Duplicator i3 v2 printer and can not get the Support touching buildplate to work with out breaking up all the time with PLA+. I just used PLA and it worked all right but PLA+ comes out bad as per the photos.

I just changed the Fill Amount from 15% to 30% but it works slightly better. I have tried Bed temperatures from 40 degrees to 70 degrees and the print head from 190 to 230 and still bad Support.

It starts to print good but after a few rows the print is all broken up in the Support only. I just changed the Fill amount from 15% to 30% and is was good enough to print the item but the Support was not too good.

Can I make the thickness of the Support thicker in the Cocoon Create program as that would work as the items print good.

I can not attach this photo to the previous post. This is what it turns out like with Support all broken.

check print speed isn't higher for the support.
I know infill speed is usually higher than print speed - so maybe it's the same with supports.

[Firepower]

Yes. You are correct the Support prints way too fast.

I'll keep looking on the attached photo to see if I can find out how to slow it down.

Can you see any suggestions where I would slow it down on the attached photo. Maybe it is the Infill Speed and there is no separate speed for Supports.

Thanks. Much appreciated for your comment. I may be able to print well almost properly after all these years.


EDIT: I reduced the infill speed but it did not slow down the printing of the Support.

I just lowered Travel Speed and Inner Shell Speed and that did not slow down the Support.

I am using an old Cura. Looks I need to use the new Cura.

In Cura Select Preferences Click
In Preferences select Settings Click

Type Speed in the Dialog box

Put A check in Support Speed boxes that apply, This will allow you to view and change these settings.

If they do not appear Then upgrade to Cura 4.0.0

Roberts_Clif - Thanks for the reply.

My version of Cura does not have speed settings for Supports. Thanks for the link.

I have wasted a lot of time with the printer over the years but hopefully getting there now. Firstly I did not know to install my printer profile and never getting the Support to print right has been a problem. But recently putting on lock nuts on the bed has made a big improvement to getting the first layer right. The wing nuts that came with the machine were useless and moved all the time. etc etc

I should be right now after I work out how to get the first layer of PETG to stick properly. Guess it must be getting the bed perfect.

pet-g needs to print slower than pla.
anything much over 40mm/s and you'll struggle.
Also needs to be a little hotter than pla.

buy simplify3d :-)

The first layer is your most important layer.

I believe you are retracting to far try 4.5mm with a Z-Hop of .075 reduce fan min to 40 and fan max to 60.

I slowed the speed to 40mm/s and looks like it is working now.

So many things to know about the 3D printing.

Thanks

Thanks for the good information. I got most of what you said and I think you mean the 4.5mm in Minimium Travel. I'll check out that link also.

I'll try those settings after the current print I am doing and let you know the difference.

EDIT: With slowing down the speed with PETG and your changes I can get a reasonable first layer which is an improvement on what I was getting.

But before I go any further I will load the latest Cura which will take a while for me to get going I guess.

Thanks
