I am using Slic3r. Actually it seams I identified the problem. Slic3r had a threshold of layer time above which it turnes off the cooling. On my object that happened exactly in these layers which had the bottom structure for the wider screw hole... but is it possible ghe absence of cooling makes such a difference on the outer surface?

For better understanding: my holes start with a small diameter and then become wider to embed the screw head as well. The first thickness shift appears when the hole in the middle increases its diameter. The second one when the other 4 do the same thing...
Oh and the problem is reproduceable.

Hi I am facing a very weird phenomena. My walls generally have a really good quality. When I print a solid cube there are no deviations observable. Nevertheless when printing an object with screw holes inside, a change in diameter ob the holes causes significant expansion on the outer surface. Does anyone have an what could cause it?!

@droftarts I tried a G4 as well. It also paused the execution of the trigger Script, so unfortunately not a solution.

@bludin I have faced that problem 2 weeks ago and also tried to find held in the forum. Unfortunately it seams not a lot of people are trying to use triggers that way and even the developers couldn't really help. In the end I found a messy but functional work around by adding a number of M400 right after the M582. I needed one M400 for each G1 command in the trigger script to make sure the main code is paused long enough. But I am not sure if that is a general rule
I hope that solves your problem.

Ps: Am I right you need one trigger per tool? That might be possible with just 4 tools but since I am setting up a tool changer with 8 I simply use one switch on the carriage which causes a message for the user to remove the tool. Maybe that is also an easier solution for you

@cdl1701yahoo-com ah interesting
What did you use as a T-lock? And is there a reason not to try an electromagnetic coupling?

@cdl1701yahoo-com why exactly do you need another axis. Is it a special kind of tool changing setup?

Hi I am trying to create a more advanced menu structure in my user macros. The idea is to have a Button with changing text that shows the currently chosen tool. I tried to rename the directory with M471 inside the tfree and tpre scripts and it actually works. But the problem is the DWC is not refreshing. I first have to open the directory (shows an error) and then it recognizes the new name.
Is there a way to make the DWC update immediately?
Best regards and thanks

For those who might be interested
I found a solution: Right after the M582 a couple of M400 commands have to be included. It looks like one needs as many M400 as there are G1 commands in the trigger file. It is more a workaround than a clean solution, but works fine for me
