The cloud based part of freeware is absolutely an issue for a business. I am able to save my models locally, but I am sure it talks out in some way. Data logging is a big business. Hence the if its too good to be true, they are getting theirs in some way. They are not publishing the models as far as I am aware. Something to look into I suppose. But I really use it for home hobby and study for professional development.
As far as getting up to speed on CNC, there are Military, Veteran, and Workforce programs that are free or close to free. I attended a fantastic one last year for a machinist school and became certified in a number of areas. The schooling is 100% free through the DoD and it is the place of duty. Just go to school and learn machining. It has been fantastic on my job searches and an overall amazing experience. For DoD members it falls under DoD instruction 1322.29.

Under that program Soldiers and Veterans can learn jobs skills for free. Welding, Machinist, Maintenance, supply, Health care, IT..ext It does not require TA or any GI bill money. The only catch is, the participating schools can not always support housing, food or travel. That's all on the individual and TDY or PTDY is illegal in this case. Most the programs are six months or more and if a exiting service member, they must be within 180 days of separation and have a BN commander signature on their release forms. Soldiers or veterans can search for more info, but also contact the SFL-TAP office on base. The program is not well known and requires some hurdles to get in.
If anyone is interested in the CNC class that I attended, please PM me and I will provide the contacts I have.
