Getting started with Atomstack A10 Pro

I am new and beeb trying to play with the the AtomStack A5 pro but i am running into issues. I wanted to use it to glass etch but whatever setting i use is not even burning the tape which i read and saw could be used. It is just blue painters tape. I have tried the wet paper towell method and it still is not doing that. the other issue i am having is lining up what i am wanting to etch and cut. I have tried to mark some bamboo coasters with words but it was off by a few inches. I am lost with all the settings and how to do much of anything with this. it would be great to do because i can do etchings quicker and cleaner. any help would be great. I should note i always start my machine from the home position which is bottom left.
