Welcome to the forum I for one will be looking forward to your mdf build on such a low budget I hope you start a build log with a cost of the parts as used. The only thing I can add at this time would be, is to use a power supply of at least 48V and better still 68V so try and make sure the drivers can handle that. Good Luck with the build. ..Clive

You might just be okay if you know your materials
Lightweight linear bearings and belt drives are okay for lasers, plasma cutters and 3D printers because there is little tool loading. You can come unstuck with a rotary cutter because the tool would rather rub than cut. If there is any flex in the system the tool can get left behind and then catch up in a rush when the driving force suddenly overcomes the resistance. This gives a stop-go effect which you counter by reducing the cut depth. So what, you have all the time in the world, what does it matter if it takes forever? Well, the longer it takes, the longer it has to go wrong
