Does EstlCam can be used for creating plt files ?

Hi I'm working on a Stepcraft D series 840 with a Winpc Nc as the driving software, there is a ton of issues with this software and i don't know where to start.

First point i use EstlCam because a Stepcraft employee told us it was a good solution. And from what i know now it isn't !! it might be the worst software i have ever seen !

Let me explain. I was doing a simple task cut through a 2 mm plastic window. So, i place the plastic window on top of an mdf plate to avoid destroying the T slot table or the tool. I created a plt file with estlcam with as the reference the top of the material and cuting with a 2 mm depth. Then i went on win pc nc and i parameter the x and y 0 coordinate i save then use the tool length sensor to get the z=0 exit then start my program. As you can imagine nothing works. the cut wasn't 2mm deep but close to 1 mm so i stoped the program on the software( not the emergency stop). Then because it didn't cut as deep as i wanted i decided to create all over again a new cuting program on estlcam this time i put the refernce on the table and said that the material was 2mm thick. I put the programm and start the cuting program. and it was even worst than the first time ! in a first place the x and y origin coordinate have changed between these two program and it didn(t cut for 2 mm as i asked but for almost 4 mm !

For the moment my opinion is simple it's on estcam or winpc nc but one of them is pure garbage and i don't know which one of them now( looks more like estlcam) because it is obvious that when you parameter a 2 mm cut it will cut for 1 or 4 depending on their mood and in the middle of nowhere the origin can change ... this software is no joke the worst software in terms of dimension

If someone can proove that i'm wrong i will be more than happy to hear from you.

I attached the dxf and plt file so you can take a quick look !

Thank you
