Carbide Create does not have a facility for putting text on a path. You would need to set each letter separately (or convert them to curves) and then drag each into position and rotate manually.
Much easier to use a program which has that as a feature.
Inkscape is a free/opensource option, but not sure how well it works w/ screen readers:

Serif’s Affinity Designer is a popular vector editor which works well as a front-end — just export SVG files from it at 96ppi to import into Carbide Create.
Naturally, if you have any specific difficulties w/ Carbide Create please post them here or send them in to support@carbide3d.com and we will do our best to assist.
The older videos show a menu bar which Carbide Create no longer has, but all that functionality is still present — it just migrated into the main menus — the one notable interface change is that the key for adding or removing an element from a selection has changed from control to the industy-standard shift.
