Subject: Power Requirements to Mill HSLA & Mild Steels

I am planning to purchase a CNC Mill or Mill and CNC Kit in the next
month. I would like to know what size of motors I would need to mill
High Strength Low Alloy (HSLA) and Mild Steels. This is for hobby
work so removing a ton of material quickly is not necessary, but then
again, I don't want to be taking really small cuts just to prevent
problems.

Also, any advice whether to buy a complete CNC Mill or a manual mill
and add a CNC kit to it? Any suggestions about CNC kits...which ones
are good or not? I need to stay on the smaller-size of mills...mini-
mill-sized or a step larger.

Thanks,

David S.

Robert,

the small pcb should be able to be removed just by loosening some
terminal screws. At least it looks that way in the photo.

Of that is the case, take a photo of the back and the chip and put it
in the CNC-pics group (CCED, this group, has the files section locked.)

I really think you are just a simple circuit away from step and dir
with a small add-on board.

Also, I hope you got a few of these.

Dave

That stuff's out there. My brother was involved in the installation of all
of
the "Traffic Cams" for a couple of TV stat ions around here. It can't be
all
that complicated, and those are remotely controlled, by way of a radio
link.

It's easy stuff if you've done it before. So his success will be
contingent on his ability to put such a system together. Me? That's a
piece of cake however, when it's at 12 axes it very hard to keep
things straight (literally and figuratively) :). That's a hexapod with
a 4 joint gimble snake with an end effector. I don't think I'll ever

I have a customer that I have done a few retrofits for and now he wants me
to retrofit his Turn Center. The problem is that he does not have the
electrical/cnc manual. Since it uses hyd for the spindle chuck and tool

Subject: Question on Power Supply

I purchase a Microstepping driver and (4x) Bipolar Stepper
motors and now need to find a power supply to run them.

I am not exacly sure about what the power supply it needs to
be. I was hoping someone here would take the time to look
at these specs and give me some direction on a power supply
I need to purchase.

Bipolar Stepper Motor Specs are:


4 Wire Bipolar Stepper
2.3 Volt/Phase
80 oz.-in.
1.5 Amp/Phase DC,
1.5 Ohm/Phase,
Steps 200,
Size NEMA 23



Driver Specs.: (Complete Data www.pennswoods.net/~luke1027/BSD-02x4
Manual.PDF)
Functional description of BSD-01v2 Module
The BSD-02x4 module is a complete 4-axis microstepping driver suitable
for
driving bipolar step motors from 50mA to 2.5A and up to 30V.
Each of the 4 axis can be set independently to one of the 4 stepping
modes: Full-,
Half-, Quarter- or Eighth- Step without requiring any phase-sequence
tables, high
frequency control lines or complex interfaces to program.
Ideal for applications where a complex microcontroller is unavailable
or over-burdened.
Features
· +/- 2.5A (3.0A with Forced Convection), 30V Output Rating
· Crossover-Current Circuit Protection
· Under-Voltage Lockout Protection
· Thermal Shutdown Protection
· Automatic Current-Decay Mode
· One Common Enable Input for all 4 axis
· Built-in Translator
· Buffered Step, Direction and Enable Inputs
· Reduced audible motor noise
· Increased step accuracy
· Low Quiescent Current (10mA MAX)


I am assuming that the DC voltage on the supply must be


fixed at 30V or variable up to 30V and the amperage must


3.0A or a little less - and it should be regulated Voltage. This is


determined be the Driver specs.... right? So the motors get their
voltage through the driver as well as the Signal and Directions...


Right?



Thanks,



Luke

Subject: Re: Question on Power Supply

I would use a 24v 7.5a power supply. That would give you max amps
for your driver on all three axis at the same time, theoretically....

look at www.mpja.com. They used to have a 28/14VDC power supply
that works very well for the smaller stepper drives. I use mine
with a Xylotex.

I found it easier to buy one off the shelf than get a
cap/torroid/bridge + whatever else to build one. If I ever go to
Gecko's and need 60+ VDC I would build my own.

Luke,

It looks like a power supply in the range of 28 to 30 volts. Just check for
the maximum that you can use.

You can build your own power supply. All it takes is a transformer, bridge
rectifier and a capacitor.

Most power supplies are unregulated.

If you decide to build your own, I can help you.

I also have an interface breakout board that will help.

Robert,

When you say "Just check for the maximum that you can use."
You are talking about the max. voltage that the Driver can handle ... right?
Which in my case will be 30 Volts. So I would need a transformer that will
put out 30V. I would like to build my own, just for the sake of learning.

Luke,

I agree with Ron. For a small power supply it would be best to buy one.

If you want to experiment and build your own, look for a transformer that
has an output of about 18 volts AC at about 4 amps. This will give you a DC
voltage of about 26 volts once you run it through a bridge rectifier and
charge it up in a capacitor.

The next step is to find a bridge rectifier and a filter capacitor.

If you decide to build one, please contact me off line and I will help you.

Subject: Model Engineers Workshop volume103

Does anybody have, and would like to sell, Model Engineers Workshop
Volume 103 (December/January 2004/2005)?

In particular, I'm trying to get a copy of Dick Stephen's article from
volume 103 titled "Retrofitting the X3 Milling Machine".

I've tried the publisher, www.wiseowlpublications.com, the public
library, etc., and I've been told that it is not available.

If you have copy you'd like to part with please email me at my
yahoo.com address.

mmeyers1111

Thanks...

Mike

I can send you a scan Mike. I'll dig out the article today.
I'm keen to see how you go. I'm gonna do a servo refit to an X3 in a few
months.. What size steppers are you planning on using?

Subject: Re: Question on Power Supply

Bruce:

It frustrates me there are SO many wizards "in here" who spec. newbies'
power-supplies, and it is clear 80% of them haven't a clue!

First, you say your drivers are rated up to 30 VDC. An unregulated 28 or
30
VDC supply WILL exceed that, at least at times, and BLOW your drives. Use
no more than a 24 VDC unregulated supply!

Next, your motors have two windings drawing 1.5 A each @ 2.3 VDC. That
simply means each draws about 7 watts. The drives are PWM types and
supply
24-30 VDC in short pulses, the pulse-width determined by the speed of
rotation at
the moment and the need to hold the current per phase to 1.5 A. So, say
you
have only 24 VDC raw voltage; a 7 watt motor/driver combination will need,
then, only 7/24 = 0.292 A. If your 24 VDC supply will deliver, then, 0.3
to
0.5 A per motor, that is ALL you need! I'd go for 1 amp per motor, just to
be
sure. But you do NOT need a supply that can deliver 3 amps per motor! See
Mariss' white paper!

NO! 30 VAC full-wave rectified and filtered will result in 30*SQR(2)=42+
VDC, and that will WASTE your 30 VDC-rated drives! Find an 18 VAC
transformer!

You probably know this but the article ran for three issues 102, 103 and
104.
