Where you set 0,0 is the center on the laser and aligns to the center of the image (total pixels, so your design must be centered in the image). If it's off then perhaps your image has more white space on one side or you aren't finding center of the item (if it's rectangular you can draw lines from corner to corner and the intersection will be the center).
Just an FYI Tucker, I am running an A3 with the Mana Se board with the rather heavy Z axis add on, and it runs without any issues with 0.7v on the pot wiper. Is was also running well at the default setting 0f about 0.4v before I extended the rails. SO not sure you problem is strictly power. Unless you have the belts VERY tight.
Hope that helps
Upper right corner of the G-code, click "View" and you will see the finished simulation. Refer to the manual for controls to run the simulation but it is not necessary, in this example you can see yellow is low power and blue is max power.
Many thanks again for your help, seems best to upgrade the workshop computer and periodically bring it back indoors for possible upgrade to T2 unless I can find a wireless system that will communicate some 100 feet from the house or run an Ethernet cable which for practical use need only be connected to check for updates anyway again thank you for your help and advice.
@alvar0.ga It's possible using Sketch Plus (Overlay) mode to engrave and then cut, you select the cut using the trace feature to generate vector from the image. You could also load separate files or generate separate G-code files and combine them in a text editor (or just run one and then the other).
