as for the standalone sender program, this is what I use: Best CNC Software is OPENBUILDS CONTROL - Cool Features - YouTube
It’s a really long story, but basically i got a small desktop cnc back in 2017 and was learning as much as i could on the weekends and right as i bought a 4ftx4ft machine my company closed when covid started in 2020 and i had a little over 2 years of me time to spend wherever i wanted and i chose cnc… like probably too much time… and by helping others, mostly through the multiple cnc facebook groups, I’ve managed to learn a lot along my own journey.
Now I’ve got 6 cnc’s, 4 laser engravers, and 3 3d printers in my shop (a few are shelved, I’m not actually using them all at once) I’ve been blessed enough that I’ve only paid for 4 of them though the others have been provided by brands who wanted their product tested/reviewed, or a red-lined assembly guide, or a random giveaway I won by joining their livestream when the company was in its infancy and they were doing weekly giveaways to boost the customer base…
