Hello,

Im not exactly sure if this is the right place for the queston but here it goes.

We are currently looking for a cnc punch for our prototyping shop and have narrowed our options down to...

Is there a way to find this out for sure? A way to tell, if its stepping or if its field oriented control? Thanks.

So what does that mean for stepping? How does that effect the steppers ability to step, or microstep? How can the stepper be accurate if the step of the angle never aligns with the lines of the...

Hi,

There is a video of the drive I am using with the motor. Thats not me but a very similar seetup is being used in the video:

In this video, the...

So, does that mean that if my stepper can only position to the step resolution, either in full or fractional, the encoder wheel is always going to read in between two encoder lines and be inaccurate?...

Hello,

I asked this on another forum as well but, didnt get enough answers.

I have a question that I cant seem to get my head around, would appreciate some help.

I have a 1.2 angle 3 phase...

Hey Matt, Dick and Mactec54, thx for replies. I will definitely look into the dancer roller but, the basic friction clutch seems easy enough to make. Any ideas for the friction material?

Thanks! They look great and do exactly what I want but, quite expensive arent they... Any cheaper alternatives that do this?

Thats a great way to do it but, this machine is not supposed to have any electrical components, its a purely mechanical machine.

double post

Thanks for the reply.

The application for this is for winding paper into a certain tightness to make a certain type of composite that we are experimenting with.

How can I add the resistance or...

Hello,

I am trying to design a winding machine and I need help in designing/understanding/finding the right component for the task. Below is a simple diagram of the machine.

I cant remember exactly, believe it was around 3500-3800 N of force. The belleville spring used needed about 720 pounds of force to be flattened completely, I used 100 of them, two pairs facing each...

I know its been a long time, but many things have changed since my last comment on the project. I became a Ph.D. in Industrial design and now have a child and etc. So life got complicated and I am...

well...**** found it...dont ask how

its Amphenol C16-3 Shell 1 14+1 Pin

Most Techno and isel machines use it for future reference to those seeking it.

for searchers:

Techno cable...

Thx for all the replies.

Ive been looking for a while now and no luck. The Pin thats missing on the bottom should be a dead give away but no luck:(

Hi all,

Trying to find the pictured connector, but cant get a name or a code for it, tried contacting Isel but no answer yet.

Thx.

Hey people,

After my looong ATC spindle project I didnt think I would be coming back to the DIY CNC scene, but here I am, and this time I might just be in for the long haul.

I got my hands on 3...

Here are couple of names:

"DriveXes Motion" for the company and "XerXes AC Servo" for the first product

"ServoXer Motion" for the company...

...maybe more to come:)

Hi,

Dont know how your project is going, but I hope its well. It looks alot like the one I was working on back in the day. I had to leave it for a few reason, one of which was the rpm limitations...

There is a lot of ppl watching this thread Xerxes, please keep up the good work as we all want to get our BLAC motors going:)

Thx.

Hey all,

I just saw some cheap stepper motors and it got me thinking about something that I had thought about in the past but never asked about ( I decided to use servo motors so I just forgot...

Thx for all the replies:)

Nice to see some people from before;) Anyway, I am really glad for all the feedback, but the design has changed pretty much from being a 30 taper to a much smaller collet...

Hello people,

Its been a while since I wrote anything here in cnczone but, there were reasons for this, mostly personal, financial and such that are mostly gone. Since then I have moved to Europe...

Hi guyz,

Sorry been away for so long, but I have been going thru very rough times financially and I had to put a hold on the project so I can buy myself food, literally.

The project is not...

Hi,

Bloy is absolutely right, dont think about using any kind of water by itself. Coolants have rust inhibitives which prevent oxidation of metals, which is crucial, obviously.

Just keep that...

Hey Swede,

Yes I thought an electric actuator would be more suitable, thats why I used an electric actuator on my test setup and I was glad with the results I got.

As a side not, I do not want...

Hi ppl,

I was able to get my hands on these two drivers; one of them is for the big servo (sinusoidal type PWM) the other is for the rotary table (Digital PWM). Now that I got the drivers, would I...

I said I post last night, but got of work at 4 AM and was kinda tired by that time, so here is a late post.
