Thread: Wooden CNC
Your looking for something to engrave and cut MDF, that guides your search to start with.
Different level of machine to cut out motorcycle yokes in quantity to a machine for V-carving names in MDF toy boxes ;-)
Come up with some specs for what you need to do and sure there are some suggestions from the panel on what can get to do it in your budget.
If you are just v-carving soft woods or MDF you will probably get away with using something like a palm router as your spindle.
Brand new £43 delivered, if that helps the budget a bit.
If not, keep an eye on ebay/craigslist etc for a small secondhand plunge router you can probably get one for under a tenner.
As far as the computer side of things goes, what is your computer experience and can you beg any help from family or friends with better skills?
Mach3 will set you back about £150, a second hand PC from ebay etc £50-£100. This eats into your budget a fair amount.
Alternatively you could look at the Machinekit OS running on a beaglebone black (£40) with a PBX-BB bob (£60)
The BBB has a huge advantage because the processor is specifically designed for industrial motion control with 2x 200mhz PRU's that deliver much better performance than a windows x86 PC could ever do.
It will save you £150-£300 on computer/software/bob, as long as you can manage not to runaway screaming from the linux.
For stepper motor drivers, the TB6600 drivers can be purchased for £9-£10 a piece from aliexpress, buy them one at a time and avoid going over the £15 import duty limit.
You can build a much, much better machine for your budget, so don't be disheartened.
Mach3 is $175 if buy your license direct from ArtSoft, so more like £120.
If you shop around for a decent ex-corporate machine such as an HP Dual Core 64 bit Athlon desktop or similar they can be had from Ebay for £35 to £40 delivered.
Still not peanuts but actual pricing based on my recent shopping experiences,
