prepreg cutting file problem

[luiging.]

in creating a nesting file for cutting a prepreg skin, I found a strange problem. This file is part of a long series of files that I have created following the same steps and using the same save formats, but this file in particular seems corrupt. in detail I proceed as follows.
using special software I get 2d templates from 3d mathematics. the templates are in dxf format. the amount in autocad and I process them by correcting the profiles and any artifices. I set the layers, one for cutting and one for writing, respectively 0 and 3. I organize a new nested file and save all in dxf. I send it to the cutting department and usually everything works. this file in particular manifests a strange and for now irresoluble problem: part of the square is decomposed. a portion of about 1 meter left and another portion with the writing layer is transferred rigidly to the right. This effect is not visible either on autocads of other stations, nor on draftsight..... visualization, layers..... is always correct. when loaded on the cutting machine station is corrupted in the manner I described. (the cutting machine is a bullmer and the station uses a dedicated proprietary software)
resolution ideas?
similar experiences?
half of yesterday's day we have it (underline two, I new engineer with the support, though not massive, of an engineer who has been working in the industry for 8 years) spent looking for solutions that we did not find. in order:
- copy paste the placed into a new file
- recomposition from zero of the nesting with integral recreation of the writing layer
- recomposition from zero of nesting with integral recreation of the writing layer with a macos system
- layer verification
- verification of the correctness of geometries
- obviously check the file extension
- as I have already said check with other cads and other posts
Does anyone have any idea, in addition to the tautological but remarkably frustrating, to redevelop the dimes from scratch?
thanks to all those who will dedicate time to answer

Hi.
First of all welcome!

First of all I would recommend you try to use not too "specialistic" terms or maybe even give a brief explanation for those who are not exactly of your industry but can still give you a big hand if you can understand of coast you are talking (for example I understand what you mean by "flat" and I know what nesting is, since it is part of my daily work, but maybe some extremely experienced autocad user may not know, but you and you

some images always helps

I don't know how the service of the machine you use, but if they have a dedicated software, they will also have a service service, and they can help you understand why a design that in autocad looks fine, is not properly interpreted by their software.


ps: the layer you define "writing" would be to mark instead of cutting?

check that there are no abnormal entities that increase the size of the useful cutting space and deceive the laser.
for example very small points or lines, maybe on layers off or on default layers, or blank blocks.
usually just zoom extension to notice it; then with a quick selection verify that there are no blocks. Finally do not forget the purge

hello thanks for suggestions.
I apologize if the language is not understandable, I thought I climbed it sufficiently but I will further explain the contents.
I don't even know how car assistance works since they haven't hired me yet, and the environment is uncooperative, which is why I'm going to take more responsibility in this sense or collide with staff who don't give me feedback. I'll see if that's feasible.
The writing layer writes its own, has a marker instead of the cutter.... is a cutting machine of the same type as those used in the textile industry. therefore owns two tools, one cutting and one writing to give directions to the worker on how to move during the lamination process. I think, however, to "mark" you meant something very similar if not the same.
I'm sorry about the pictures, but I can't resort to them. they cut my hands if they see what public internal material. although this has no chance of providing no industrial advantage to anyone.
Thanks again

I looked for those, too. but not with all the procedures you have explained. For example, I may not know what purge is or what you mean by quick selection.
would you be so kind to explain?
Thank you.
