With respect, Rustedancient, the $350 k40 laser you bought it really a piece of junk in the overall scheme of lasers. Chinese stuff at the bottom of the quality scale is cheap for a very good reason.
There is quality Chinese stuff also- but you will pay for that.
If you bought Ray’s $200 upgrade you’ll have a far better machine, probably worth more than the $550 you’ll have spent.
Or as Blake says, buy a Ruida controller for $250 or more, and fit that- your learning curve in installing and setting it up will be sizeable however.
You’re not going to get quality stuff without paying for it!
Have fun deciding on your best options!
