the lowest i can st it is 230v, is that ok?

Hi all,

Does anyone know off hand if the ebay Chinese spindles will work on 380v 3 phase Eu power or 240v, or do you have to specify which power you are going to use? I have a 380v 3ph in ABB VFD...

Does it make a difference it being 2.2kw compared to the 3kw chinese spindle?

Hello all,

I've been in the market for a Chinese spindle lately and have noticed that a few new "metal working" spindles have popped up in the market that are supposed to endure being able to cut...

Hah, no doubt about that. Guess I need one of these because I only have win 64 on my mac. Will it run through win Parallels on the Mac or do I need a dedicated machine?

Wow, that sounds like an amazing bit though. 4-10times, hope they don't break!

Thanks for the thread link too btw.

Hey Gerry,

Just curious, what would you recommend as far as bits go for cutting acrylics and plexi? Really appreciate the info on the bits and how to make them go further, thank you heaps for...

Thanks for the helpful information. By the way, you're CNC router design is very solid looking. And it looks cool too, quite modern and sleek. Didn't know you used the smooth stepper in it. Does...

Very nice. Thanks for the info. What is the length of travel and who many IPM do you get with it? Is it better to go with ethernet over USB?

Thanks for the info!
Chris

This is awesome! Thanks for sharing this. Very inspiring!

Looking for some motors to drive my project, but am stuck on this.

My first choice is to use the PK296A2A-SG7.2 as recommended with the gear box but that gives some backlash, then I heard the...

Hi Everyone,

I'm wondering how the smooth stepper would function on a larger table design as I've heard about them being installed a lot in mills, and if I get a smooth stepper, will I still need...

Wow, thank you. That is some great information on bits. Very informative indeed. So after 4 sharpenings, you can do 4 more but as a 5/16" bit size?

Thank you,
Chris

Awesome thank you! I'll get one, or two. How long do they last?

Chris

Thank you!,

That's a good bit of information. So what would be the best 3/8" bit for cutting patterns out of 1/2" plywood to get a smooth edge? Also, is there any particular company I should buy...

Hi all,

For these open source machines, what bits would be considered the best? Anyone have any info on what I would need to cut relief in MDF, plywood cutting, ash hoop pine, alum, and...

Thanks for the advice on this. I definitely have the experience and fabrication skills to weld and put together a machine, just been a few years that I've had to do it is all. I'm sure thought that...

Thanks for the advice. I've been looking at the mechmate, and it sounds pretty good, just seems like it takes a lot onger to put together than the CNC router parts. Perhaps I ought to build s...

Are the gantry parts better to be extrusion or weld? I have a welder, and can weld, just need some practice.

Thanks for the info.

Can anyone recommend a full servo/drive package, or links to them that would be good value for Nema 34 applications? Also, are the Gekko drives the most reliable thing to drive them with?

Thanks...

That's seems to be true!

Cheers,
Chris

Hi there,

I'm quite new to al this so you'll have to excuse my lack of knowledge here. But am wondering what the pros and cons would be for either a welded metal kit vs one that is machined to...

Great, thanks!

Anyone have any experience with the chinese spindles? Any good?
Chris

Thanks, that is what I was wondering.

Just curious, what other software will correct all the motors should one fall out of step? Seems there is no huge cost benefit to having closed loop if you...

Awesome, thanks, do these monitor all axis simultaneously?

Thats helpful , thank you. How would i go about doing that is the question? Does this favour servos?

Cheers,
Chris

Hello,

Total newbie at all this, but does the kflop enable all the servos/closed loop steppers to be monitors all at once? In other words instead of each one individually correcting, do they...

Thank you for that, the columbia looks awesome. Are the Hybrid drives any good as I've been looking at the hybrid stepper closed loop systems and think that might be the way to go? The PRS alpha...

Oh cool. I thought in order to cut 10" per second, I would need something higher performance, hybrid drive, or something that can utilize a 5k w spindle. I'm working with some fairly intense...

That looks good, the mechmate, thanks for the link. How much does it cost to get into one of these? Any ideas? Looks perfect for what I need.
