How to make exact size svg fiels for eleksCam software? Answered

I bought this DIY Chinese laser machine. After some trials. I got it all fixed and yes it cut and engraved. They gave me 2 softwares. One is Engraver Master which i found useless as non of my dxf files show up properly. it's always warped. Then I tried EleksMaster. This software is great. But there is a major problem. It cuts only texts and engraves. But when i insert a new image and ask it to cut outlines, the image does not load up. I even checked this instructable and asked help. So to cut I found SVG files work. But there I encountered another problem. I cannot resize the images. All SVG files opened through PicCarve Appears way larger. Sizing is very important for me. Sometimes the size is way larger than my cutting area. It's really frustrating and annoying. It's more than a month now, and I'm still unable to cut custom cake toppers cause I can't seem to get a single software right for me. Someone said to try laseraxe but that does not connect to my laser. I have no clue why. So please help me so that i can cut the exact size of an image using PicCarve . Ther is a place that says input G Code. I'm not sure what that is. Currently I'm reserching that too. But if Anyone knows...Plese Please help.

The Eleksmaker support is usually quite good and there were topics about the problem with outlines and images in their forum as well.

Having said that....
When I started with my CO2 Laser the first order of business was to get rid of the controller and to put my own in there.
Chinese adaptations and software are just not as advertised in the consumer sector.
You said you used different softwares with various outcomes.
Can I assume that those programs are able to properly communicate with the machine?
Or do you generate code with the programs and then load that through the software that came with the machine?
Either way your main problem might be resolution.
Images should be resized to a workable resolution.
For example if you have nice pic from your 40mp phone then your software will struggle to get it right.
Unless you can do extreme fine details with your machine a resolution of 100 to 300DPI is plenty.
Above that and you ask for trouble.

SVG is a vector format, so the "resizing" has to be done in the software.
Vectors however come with their own problems if the engraved size is not enough for the detail level.
In most softwares that offer a simple interface a click on the image should open a dialog or popup to set the dimensions.
If you use a normal image format like PNG, JPG, TIF, BMP and so on it helps to convert it into a 1bit BW image.
Depending on the raster you choose the result in an engraving is much better than a gray scale image.
If you do need true gray scale then try to convert and rezise before using in your engraving software.
Do a test and see what happens if you resize your image to something quite tiny.
If that works for the visibility and placement in the software then increase the sie/resolution until you find the area where the program craps out.

Have a look around what people use that installed GRBL on their machines use for images and so on.
I still use my home cooked Inkscape plugin and Marlin based firmware with Laser addon LOL
Time have moved on, my machine not so much.
One day it gets a proper 32bit controller though.
