Keling 640 oz in steppers- like these. I use gecko drives in this system too- I think one or two are the 'V' model.
Your overvoltage theory seems very plausible- can you suggest a way to remedy...

I've been reminding myself for at least a year now to try and sort out this quirk of my machine and I finally remembered:

So I have an old Tripower bridgemill that 99% of the time I use manually,...

In this case, the total length of this screw is 14" including end machining, and its 20mm diameter. What do you mean by "Ac bearing?" I have a floating bearing block I can use that has one deep...

On a semi-custom build I'm working on, I have the standard rolled ball screw with fixed bearing block setup in the standard Y arrangement. The ball screw is securely fixed on one end and floating on...

In spite of that long screw, my X axis actually has around 25.5" of actual real movement, so hopefully we'll be ok. It'll be about 2 weeks until I can receive this assembly.

Thanks for the feedback! I have to admit I have the same worry but there's not a whole lot I can do about it until I get my hands on the delivered assembly to assess. The original Z & Y single nut...

Ok, cool. I'm going to go with the double then- thanks for the input. I'll have to order from another vendor- I hope they are comparable. The "TEN-HIGH" units worked out really well. The new...

Trouble is its also impossible to say what it's purpose is other than prototyping- that prototyping involves cuts with nearly every material and tool type you can imagine (and some you probably...

So I've been a little recently frustrated with an abrupt lack of response from these "TEN-HIGH" vendor on Amazon (before CNY- which I realize is now but this was before they had an excuse) regarding...

So I have a small shop used for prototyping and have gotten some good use from my Shopmaster with some coaxing over the last decade. 90% of my use has probably been manual and of that, another 80%...

Well, I guess you could look at it as machines that COULD produce a good result would want to tout that as an accomplishment, and no response would just suggest that machine isn't up to snuff. I...

Thanks- and I agree, the differences can be subtle. I had this same conversation elsewhere and wear and tear on the machine was brought up as a valid strong contributing factor. I think the cool...

I'm preparing to invest in a nice FDM (FFF) printer soon and of course I'm primarily interested in the physical features of the output parts- layer bonding, materials, texture, support structure and...

I see that I neglected to include that this sphere certainly needs to be hollow, and since it needs to be more than a hemisphere there will necessarily be an undercut that could only happen (with...

I need a hollow sphere for my current project.
I have a mock up of this made from a little glass snowglobe, which is actually a pretty darn lucky likeness of the final product. Basically I need a...

Hey, thanks for the reply! I'm surprised that your description suggests its that difficult. I would think that line following would be a pretty elementary process? I actually have what could be a...

I'm just testing out RhinoCAM, but I'm familiar with other CAM software. I have a good starter project because I think it's easy, but of course I'm doing something weird with my machine.

I'm...

Also interested- would love to know the price. I'd like a similar spec/capability in a smaller scale unit suitable for a home-shop.

Ok, I have a quick question today- well, two questions really. Here goes:

I have a 3-in-1 Tri-power machine and I haven't had the opportunity to use the CNC lathe feature before. Right now my...

Hi,
I've found a few copies of the file "MACH3B.PST" around the net and I've tried repeatedly to use it with Mastercam X2. At this point I don't think it's the mastercam configurations, but...

Hi Ron,
Thanks! Oddly enough though, I didn't receive it. My usual email is:
[email protected]

If that doesn't work, feel free to IM me or call me. I'm all about the new ideas! :)

Hi Ron-
Thanks a lot for all the quality info! Much appreciated! I thought that the text on that plaque style looked to be all the same, but I'm glad to have it confirmed. I actually think that's...

Because it would cost me more than 6x more than what I can do, and also because I would like to have closer control of the details of the design.

That's not the company that I'm talking about, I'm just citing their styles as an example of what I'm describing.

Ok, so I've got a really great arrangement set up to make my patent plaques, but there is one catch to the situation: I need to supply my own art to print.

Soo... I'm faced with creating...

Actually, I've got a situation worked out that I think is going to work quite well for me. The only catch is that I need to supply the artwork myself, which is going to be a little tricky. I'd...

Hi,
I've been on here a while in the cnc forums, but this is my first visit to the engraving section- hope this post is okay.

I'm getting my own business started on a shoestring budget, while...

All else being equal, it would be nice to have the option of selecting ballscrews with a .1" pitch to match the dials on my machine. I still do manual operations often. Any suggestions there?

Quick (noob?) question: Could you summarize the conclusion that you arrived at there? Why would it never work? Do you mean only in the context of the geckodrive controller-- so it could...

Wow... that one line of advice just solved ALL my problems! I so wish I'd discovered this thread earlier! THANKS!! :cheers:

PS. this advice still applies optimally to the 640 in/oz motor from...
