That is the ultimate goal of my friend and I... bang here is your complete package, here are your instructional videos and manual. Here is the number of your installation coach if required... I see demand being in the 10x20 to 12x36 lathe market
Hate to be such a downer about this but after almost 2 decades of experience with developing, building and selling ELS kits the one thing you can be sure of is that the market is not what you think it is.
Also the costs of everything are going up which will include tariff barriers against getting things made in China. Sure you can get cheap stepper motors and drivers and power supplies but when you start looking at completed kits for say a CNC kit for a mill or lathe that power supply, motor driver, connector set all assembled and ready to go jacks the price way up.
And then every lathe is different requiring different sensors, switches, motor pulleys etc. so which lathe will you target first? You can't afford to make the brackets and mounts by hand. Must be CNC. So how many do you make per setup? For 10 kits? You sell two and then the other 8 sit until you realize the reason yours isn't selling is because someone else is now making a kit that has one feature different from yours and people are buying into that.
What actually happens is someone decides to make a different one. They sell the 10 to 25 prototypes they had made and then they are bored with ELS kits and move onto new projects. No new development. No long term support.
It's' a throw away world now.
