ChangeAtZ values incremental ?

Posted · ChangeAtZ values incremental ?

Example: Flow is set to 107% in the profile. So flow will be 107% during printing, even though the controller (UMO) says it is 100%.

 

Then I use the ChangeAtZ plugin to change the flow to 102% at a certain height. So I enter a value of 102% in the plugin.

The controller now says flow is 102% (after reaching the height set in the plugin - at least this was the case in Cura 14.7, haven't checked this for 3.6 yet).

 

I am assuming that means that the flow is then actually 102% X 107% = 109.14%. So to actually get the flow to change from 107 to 102, I should enter a value of 102/1,07 = 95,3% in the plugin.

 

So to keep things more transparent, it is probably best to leave the flow setting at 100% in the profile, then use the plugin to change it to 107% in the first layer, and another plugin to change it to 102% at the desired height. This way the controller will always show the actual flow value during printing.

 

Am I right here ?

 

Also: if I use several instances of the plugin to change the flow a couple of times, do the subsequent changes replace the value of the plugin that came before, or is it incremental every time ?
