Hi,
Four years ago, I followed buildyourcnc.com's tutorials and build a router out of MDF. It was a failure, as I didn't own sufficient tools and talent to make a good build. I have decided to build a new machine from metal, but as I am fairly new to the CNC world, I need your advice for a couple of things.
1. I have been looking at different options:
- X-Carve: shipping cost and taxes out of reasonable ranges
- ShapeOko: too small, and seemed too complicated to upgrade for Nema 23s, and I didn't feel comfortable with buying all the pieces, and making mistakes. ShapeOko 3 is way overprice + 400 Euros for shipping to Europe makes it a no-go for me.
- OpenBuilds OX: interesting build, I like the fact that you can get standard parts from their site (except for plates)
- OpenBuilds ROUTY: interesting build, seems quite simple, but the part list does not seem reliable (after reading the discussions on their site)
2. I want a build that is like a "lego". Therefore, there are two options:
- Find a build like the OpenBuilds OX, and order parts online. Problem is: shipping cost will explode, taxes will kill me.
- Find a CNC Router plan online and order the parts from a local store that will laser cut the parts. Wheels, spacers and such could be bought from OpenBuilds. This options is by far the cheapest according to me.
3. I already own a few things:
- 3 x Nema 23 425oz
- 3 x Stepper Drivers CW230
- Power Supply 36V 9.7A
- 6 x limit switches
- 5 Axis Controller with parallel port
- PC with parallel port
- Mach 3
- E-STOP
- Bunch of electrical cable
4. I want to buy the following to complete this electronics kit:
- 1 more Nema 23 425oz: 1 Axis NEMA 23 Stepper Motor 425 oz in Dual Driver DM542A 4 2A 128MICSTEP CNC | eBay
- Spindle: 400W CNC Spindle Motor Kits PWM Speed Controller with Mount Bracket | eBay
In conclusion, here are the questions I have:
- What do you think about the links I provided for my new Nema 23 425oz and spindle ?
- With the new spindle, do I need an additional power supply, or is the one I have sufficient ?
- Openbuilds beams are hard to find in Europe, and expensive to ship to Europe. Wouldn't it be easier to find a CNC Router plan and order the parts needed from a local welder shop that has a laser cutter ?
- Can you guide me to a good plan ?
- From which material will it be cheaper to build a CNC Router: steel or aluminium ? Forget about MDF
Budget: max 1000 Euros.
Thanks a lot for any of you that will be able and take the time to help me out !
Best regards,
Eurikain.
