Hi there Machinists, this is my first post, yey!
My name is Jane, and I am a newbie enthusiast trying to design my first DIY build.
Objective:
I want to build a versatile machine that can do micro machining and hopefully some larger parts. I would mostly be machining plastics, but if I am able to machine some soft aluminum it would be a perfect.
The machine will mainly be used for making toys.
Budget:
My budget sits between 3000 and 3500 dollar. The budget includes all tools required for assembly, ongoing maintenance and shipping. I would put more money into anything that would minimize tinkering for my first build.
So far here is my plan:
I am going for 4 axis Gecko build:
1x G540
4x G723-280-4
Supported by ground ball screws, which I hope to get for a good price second hand:
+- 70cm x axis
+- 70cm y axis
+-1 17cm z axis
I still have lots of questions before I am confident with my design:
1) In practical (laymans) terms, what would I be losing by going with the G540 with the G723-280-4, instead of say 4x G213V/G203V with G734-1280-4. I understand the benefits of the G540, being value for money and no need for a break out board or extra cables. But do the pro's truly outweigh the cons with my objectives in mind?
If somebody could give me a practical example of the difference I would experience all round, the difference in implementation and results.
2) The 4th axis implementation. Some of the prices I've seen for kits are shocking. I'm not exactly sure what I need and where to start looking. Any guidance on the rotary table and implementation would be very much appreciated. Also, they seem to come in standard sizes. Should I think about building my own?
3) Spindle: I'm thinking of spending about 500-800 (could stretch for the right thing) on the spindle/router. I am struggling to find prices for these things, it seems like an industrial underworld.
Some advice for those who have worked through his before would be great! Thank you.
