Brains Development / Re: Changing milling bits
« on: June 10, 2013, 09:28:21 AM »
Hi Gary,
Ohh great, sounds like you know about the Changing bits part of my project.  I have been googling and have found water cooled motors that sounds like the way to go, but I have not clue about the part where to get a head as the motors only come with a shaft and no heads.  Is there a cool website you could direct me to. I would love to upgrade my machine to be able to chage its own tools.

Thank you in advance

Correction, I want to make PC boards that will take surface mount components.  So what bit would be adivsed? THanks

Hi,

I"m using Dremel to mill my PC boards, I would like finer detail, what bits would you recommend for really fine work, I would like to start making surface mount components.  Where can I buy such bits, perhaps I should change the Dremel?

Any advice would be appreciated.


Thanks,
Peter

Hi,

I have had great support from this website and my machine is up and running, than you,

I"m now looking at upgrading my machine to change bits, I'm using a dremel and am really not sure how to automatically change bits, can someone please point me in the right direction.

Thanks in advance

Hi,

I will get on to the link you passed me on to me, I have so lucky to have some one been kind enough to assist in this way, and will be glad if you could push me in the correct direction by giving some other links about Stepper motors and theory.

Oh and the power supply is a variable one, not sure what the insides are but it has variable voltage and variable Amp settings which show on the front pannel with LED displays.  it has the ability to run up to 30V and 3A.  Reason why I'm using it is because if by accident I short something it does not damage anything but just tempararily shuts down.

Anyways I'm excited to get on to the PDF you sent me and would love to master Stepper motor controllers.

Thank you Stirling
And again what an awesome Moderator.

Hi Stirling,

I was looking at the spec from the supplier http://www.mantech.co.za/Datasheets/Products/FL57ST.pdf, looks like the FL57ST76-0686A runs on 12V.  I will further investigate, do you have any recommended sites?

I have a variable power supply and have set the max to 12V and 0.68A, so I tried to push up to 30V and the motor behavious is the same but more interestingly on the power supply it is showing 8V ?????.  WIll have to investigate this.

Thank you

Addendum to previous Post....

And when playing around with the same settings I sometimes just get the motor to make a noise but not move at all.


Thanks again, any feedback would be awesome "I feel I'm so close to cracking this"

Hi,

Just come back from holiday and back on project for 3 days.  So I built a basic machine and will send pics with next post.  But now I can not get the motors to run properly, they run very strong and very slow.  Using the 
- easydriver from Spark fun and
- motors are 0686A 12V and 0.68A. 

What I have tried to get them to run better
1. Config >> Motor Tunning and Setup
     >> Steps per
     >> Volocity In's or mm's per min.
     >> Acceleration in's or mm's/sec/sec
     >> Step Pulse 1 -5 us
     >> Dir Pulse 0 - 5

Any ideas why they are running so very slow ?

Thank you

Hi Stirling I have gone through first three videos and that is how I got the basics going.   I have found running a basic milling program the X axis works well, only time it jitters is when I try to tune it.   No worries after a struggle I found a workaround.
Will keep progress posted, thank you

So its 21:42 CAT,  I have got the basic motor running with sparkfun easydrive.  I have started building the very basic prototype 'to shy to take photo, perhaps on completion'. Tomorrow I'll go shop for 8 ball beatings to give it a smooth opeation.  I guess I'll learn as I struggle along.  Thank you for all your responses and support, this is really a great site.
Thank you again, will keep updating progress.
