Hey guys,
I'm new to this forum and CNC in general. I've been playing with 3d printers for about a year now and I've currently got 4 machines, one that I built from scratch, one that I've HEAVILY modified, and two stock machines. I understand the basic components of a CNC router/mill, but still recognize they're VERY different machines.
I'm looking at buying my first CNC. I'd primarily be using it to make aluminum parts for different machines. Ideally I'd like to spend 3-4k, but could be swayed to go higher if I got something significant in return. After a bunch of research I've currently got my eye on two machines -- one from Taig and one from Omio CNC.
Taig's website leaves a LOT to be desired so it's hard to research specifics, but I'm looking at their top of the line CNC offering:
5019DSLS CLOSED Loop Optical Encoder Feedback Control CNC Micro Mill with BallScrews on each axis with Nema 23 motor mounts, stepper motors , control system. and MACH3 software. $3495.00
I'm wondering if maybe I'm going overkill though? Is the closed loop going to give me a lot more accuracy? Do you think I'd need that kind of accuracy to mill aluminum parts for 3d printers? I've also read the Taig control system is VERY outdated and VERY overpriced so I'd like to switch to the G540 system everyone suggests. Is there a way to get the above system without the control system and save some money?
The other one I've looked at is the Omio CNC mills, particularly the x8 with the 2.2 kw spindle. Costs quite a bit less, but not sure what I'm sacrificing.
Some additional questions:
Will both of these machines run on 110VAC? I know the omio has an option for 220VAC -- is there any point in having a 220v plug installed to run it at a higher voltage?
I plan to install a sherline 4th axis regardless of what I go with. I've seen mentions of people doing with a Taig, but what about the Omio?
Any other information people care to supply would be greatly appreciated. I'm sure I'll have more questions along the way. As mentioned, if there's another machine that's a bit more then PLEASE let me know. I could be swayed to go as high as ~$6k if it's going to get me something awesome.
