Re: V 4.0.1 Start point to specific location works not anymo

Perhaps a summary of the finding (I'm confused as to exactly what the issue is) will help the devs to diagnose and resolve the issue.....

An easy hit is an easy hit! ;)

As mentioned in the 1st post.
To specify the start point closest to a given point does not work anymore in 4.0.1
unless "Print Island Sequentially without optimization" is UNCHECKED

Re: V 4.0.1 Start point to specific location works not anymo

Hi,

I don't believe it!
Here are attached another exemple with settings as every day, only the ooze shield is set for demonstration and shows definitivly the startpoint near X0 / Y0 and near X200 / Y200 when the print head changes between the model and the ooze shield.

The 3rd picture shows the same with setting to Random Start Point.

S3D 4.0.1 on Win 7 Prof.

... without sequentially print. This option has no influences to my results.

Here is the real existing print:

The objects high is 6 mm and the nobbles are caused only by my settings without a Restart value (normal used -0,13 for ABS and PLA but this is a new special filament. Lift also set to zero).

Re: V 4.0.1 Start point to specific location works not anymo

Another example:
I have the start point set near the center of the part - offset slightly to one side so i should get a 'zipper' up the side. i don't want any start points on the vanes. here's what it looks like in 4.0 (this is what i want to have)

If i slice this in 4.1 I get scattered start points, and some of them are out on the vanes which clearly are not the closest point to the specified coordinates.

Re: V 4.0.1 Start point to specific location works not anymore

This is not fixed yet? I am having the same issue. I haven't had to print anything for a long time where i needed specific start points. Now I go to do it and it doesn't work anymore.

Is there a fix?

Re: V 4.0.1 Start point to specific location works not anymore

I would do that, but I no longer have the 4.0 install file. :(
