Re: Nuts and Volts cnc article

bdrmachine
 

Thanks

I've subcribed to Circuit Cellar since 91.

It's a good start but it appears to be rushed to print. The artical
is missing prints mentioned in the text.

There is also an article in Circuit Cellar November issue on using
Gecko drives in a CNC application.
The magazine can usually be found at Barnes and Noble or you can
download the article from their web site at www.circellar.com. It
is
not posted yet but when it is will probably cost you $1.50.
The magazine is mainly for hard core Electronic Engineers. It is
an
excellent magazine if you gravitate that way.

I have moved the FAQ pages to a different server and website. If you access

than you will see no difference and the move is transparent. If you instead
bookmarked the actual pages or used the address 206.19.206.56 than you will

Re: Keyboard wiring?

William Scalione
 

John, or anyone else interested

I have a Hagstrom KE18 I will sell you for $25.00 if you want it. I was
going to build a control panel and decided to go with a touchscreen instead.

If interested contact me OFF LIST at
wscalione@...

Thanks for the links, both are a little outside my price range. I'll
probably just dig up an old keyboard and out the parts I need, since the
chips inside sell for $40+ seperately.

Re: Using switching power supplies

 

Switching supplies are commonly designed to supply current to a steady load.
Chopper type stepper drives draw current in a very unsteady manner. This can
cause the regulation circuitry fits. Jon Elson (I think) posted a pretty
good technical over view of why it can be a problem. It can also work right
out of the box in the right circumstance and at other times be made to work
with the addition of capacitors and/or resistors. I personally recommend
that beginners just use a linear supply (transformer, rectifier, capacitor)
to start with because it eliminates the possibility of problems. When you
are starting and most likely to experience erratic behavior using a linear
supply is a good way to factor the PS out of the possible problems.

Some time ago someone mentioned that switching power supplies could
be troublesome in CNC tooling. Why? As long as the supply is not one
of those that requires some minimum current, why would it matter?

Re: toolpath creation problem or wrong interpretor setup?

 

Jim,

Lot's of us willing to help, but we can not do it blind. If the problem
definitely occurs in the first 10 lines for sure, seeing them will help. If
you are not sure how much of the code processes before the problem than it
will just be wasting everyone's time.

I am sure you can understand that we can not help you a whole lot from just
a general description and no specifics. All I can suggest is to try using a
different G-code viewer program. If it displays correctly in a couple of
them the problem is likely in the machine and/or software set-up.

As some general suggestions, I like to run the part program without having a
cutter in the spindle or material on the table if I am not sure what is
going to happen and especially on a new machine/software/CADCAM
package/etc.. Then unless you are REAL sure you have all the spindle control
codes and required dwells for the spindle to come up to speed I would just
turn the spindle on before I start the program. Also I will cut the part
from wood or foam when I have made any major changes or am using a brand new
setup. Another thing I do when there are lots of changes is drop the feed
override down to a real low value and/or single step through the program.
This will also help if you think you may be experiencing lost steps. Taking
a machine and software that you are not intimately familiar with and knowing
what it will do and combining that with G-code that you are not 100% sure of
and running it with metal and nice new cutters it a great recipe for broken
tooling.

Welcome to the CNC club. It is the fastest way to destroying tooling that I
have ever experienced. In my case it is virtually always a case of idiot at
the switch. I have learned that if I can not buy 2 or 3 of the same cutter
to just not get it at all. Nothing like having a drawer full of spares to
keep you from breaking an end mill. Having only one of a size almost seems
to be an invitation to a learning experience.

Re: toolpath creation problem or wrong interpretor setup?

j.guenther
 

Here's a suggestion for you, set 0,0,0 on your machine to be a couple of
inches above the part, single step through the program to find the point
that it goes crazy and then post the code up to that point and one or two
lines after the offending code so we can take a look. That should give us a
the info we need to help you and protect you at the same time.

I am using the Surfcam 2d free version. When I import the dxf and
lay out the toolpaths for the contours and pockets, they all
simulate fine within Surfcam. But when I go to cut the part with
Master5 or Turbocnc, it tries to start motion from the bottom and
center of the stock which is not possible considering a piece of
metal is there!
When I zero the machine at the center and top of the stock and
start
the first set of pocketed arcs, they cut the way they should. But
when it rapids to the second set at safe Z on the opposite side
of
the part, the machine starts to plunge into the stock diagnally
about 1/2" from the actual plunging position, which caught me off
guard and snapped a very expensive little end mill off at the
shank
;(

The part origin is set at X0 Y0 Z0. And the manual for Surfcam
says
that you can set the part origin wherever you want to but it
doesnt
say how.

Maybe Im missing something. But shouldnt I be able to make the
first
move thats in the code,where it starts from the origin
0,0,0 ,and
move the machine to X0 Y0 and safe Z(1)before starting the
spindle
in motion and be able to continue the cut from that position
without
problems? How do I do this correctly, because Im obviously doing
something wrong.

I am hoping someone can help me figure this out, as Ive spent
alot
of time and a pretty sizable chunk of change converting my
machine
and buying the software to do this work.And Im really anxious to
put
all of my hard work to good use.

Thanks.

Jim

Re: New to group

owenlloyd2001
 

Tim & John. Thanks for the reply.
I have a chinese Mill Drill [17x7 X/Y] from Lathemaster. I bought it
last year and am happy with the unit.

As for where I am and what's holding me back?
Well, I am just starting and have no knowlege on the how and where of
the whole thing [what I need, where to get it etc etc.] I've been
reading the files section of this group as a starting point. Then
I'll search the message archives for my questions that have already
been covered [so as to not waste other's time.]
No CNC training / experience and being a machinist 9 years out of the
trade is not helping either.

My past includes training [BCIT] and employment experience on manual
machine operation [mills, surface grinders, vertical and horizontal
boring units and lathes.]
Any advice and direction is very much welcome. Either private email
at sbw@... or via this list [if allowed.]

Owen

Hi!
From what I know, it shouldn't be any difference in wiring of momentary
swiches compare to the membrane. In fact you can make membrane out of
momentary by soldering momentary switches into the rigid PC board ,
putting spacer and glueing an overlay on top - you get membrane switch.
