TweakAtZ 4.0.2 Behavior issue

[dav19e 0]

Hi guys,

Im having some behavior issues with cura's tweak at Z 4.0.2.

When i tweak at a certain layer height, it works fine but when it comes to the printing speed for the rest of the print, it just goes back to the initial printing speed... It's quite weird as the tweaked temperature remains the same but the speed won't follow for the rest of the print.

I've tried 3 different tests but i can't find what the issue is. Do you guys have any suggestions ?

I'm also using the "print one at a time" settings

There are 3 pictures of the 3 different tests i've tried.

Thank you, David

Goodday to you,

Last days I am working out the TweakatZ feature and it does not work the way I expect it should. Also it has been difficult for me what exactly is the reason. I simplified my tests with a testfile. Tweaking in printingspeed with "Tweak value and keep it for the rest" does the job, but only for one layer and next layer it comes back to the former speed at 100%. I found out that the code of doing this is in this Gcode file "G1 F900" (slower speed) or "G1 F1800" (full speed), I changed some more layers with this codes and it printed more layers at this slower speed. I wonder what is wrong. I used the version of Cura 15.02.1 (with TweakatZ version 4.0.1), 15.04.4 and 15.04.5 with TweakatZ version 4.0.2

I copied and pasted a part of the code hereunder;

Good day to you,

As far as I have the same problem as Dav, (printing speed going back to the original speed) I copied the link from Dim3nsioneer (that is a TweakAtZ_4.0.4.py file) in the opened plugin location on my computer. I had to change the extension by renaming the file to TweakAtZ.py.

Thank you for that.

Now it worked and my print is keeping the printspeed.

First part solved. I wonder if I can find more information how TweakatZ works;

"No. of layers used for change", does not do anything special. I would expect something like a lineary scale of change, that would be wonderful. Can anybody help me with Tweak at Z?

On the wiki ultimaker site, I could not find information to gain better understanding.

Thank you Dim3nsioneer for your help,

Would it be possible to find added information about the Gcodes somewhere, so I can see in the Gcode file where what command does what? Should I also have a comment on my printerscreen when a command is in action? Should I be able to see a lineary change in the Gcode and in which commands should that be? I am learning every day

Thanks,

Minke
