Radio Shack has a flexible spill-proof keyboard (you can even roll it
up) for about $35.00. Mount it on a panel with double-sided tape and
you're set.

Otherwise it will break on the edges of a spacer around the switch,
due to a flexing.

Re: toolpath creation problem or wrong interpretor setup?

Alan Marconett KM6VV
 

Hi Tim, Jim,

Yeah, like the 7BA carbon steal tap (from England) I just broke! And I
was being nice to it! I'm milling the cylinder for a Stuart steam
engine. I decided to also mill a "practice" block (CNC comes in handy
for all those holes). It has "more conventional" threading. 5-40?
Right. I probably have a dozen each of the conventional 4-40, 6-32,
8-32 etc. taps, and I THOUGHT I had 5-40 taps and dies. Never found a
single one. Easy enough to pick up, but in a similar error, I also
THOUGHT I had a stockpile of 5-40 allen head cap screws. Oh well.

On the CNC, another thing that could get you in to trouble quick is
drawing the part in one orientation, and needing to have the "setup" in
another orientation. Also, having the drawing origin different then a
convenient point to "touch off" on the work piece.

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.

Polar Coordinate based CNC

 

What all would have to happen to allow a CNC machine to be based on a polar coordinate system rather than a rectangular one. The big benefit to me would be that the single most expensive component of a router/plama type of system is the slides and drive components (the screws or rack/pinon not the motor itself) for the longest axis (for systems of the size/type I have in mind this would be to move a gantry). But I assume that would mandate a change to the controller so it could interpret g-codes as polar coordinates. Are there any controller packages out there currently that support polar-coordinates?

Thanks,

Re: Keyboard wiring?

 

I am using one of these and like it. It is mounted up at head height so
there are virtually no hot chips getting to it. It is a little funny to
type on and I would not want to use it on a system that I had to do a
lot of data entry, but on my CNC controller I am happy with it. I will
warn you that double sided tape does not work with it. The plastic is a
silicone and the tape just falls right off.

Re: Drill press & cross-slide vice

turbulatordude
 

ditto !

I did that to my old, origional drill press.

I used brass screws with wingnuts to let me lock in the spindle.
I tried milling with a cross slide vice.

I was able to take cuts as deep as 0.005" in aluminum.

one problem revealed itself when wheil cranking, I rested my hand on
the top belt guard. the cutter took a nose dive into the part. I
didn't push, just rested, but the extra weight and the flex in the
machine changed the cutting depth.

I think i got the idea from this list or the 7x10minilathe list and
someone advised me how to remove the spring safely.

Of you are intent on this approach you will find that cheap drill
presses not only have crappy bearings, but the spindle is not
stiff.

The rack and pinion gear that drives the spindle is very very
sloppy,
and there is no adjustment.
I pulled out my quill, drilled and tapped two 10-24 holes pointing
toward the quill, one from the front, one from the side. Inserted
two
brass screws with nuts to lock them down, and reduced the play
some. The
remaining slop comes from the quill spline fitting into the pulley
at
the top.

Steer clear of these keyboards. They are made of a very thin membrane
and just one hot chip can burn thru them.
Also they are very wobbly when typing. It's like trying to have sex
standing up on a water bed [ so Bill tells me <grin> ]
There are some photos in the photo section under pendant that you may
want to take a look at.

Does anyone have information on building a supplimental keyboard

DRO readouts,
and would like to build a keypad with big buttons (like 1x1"
monster
buttons, probably will be membranes as well) for the most
important

so that i dont
have to worry about hitting the wrong button or getting
cutting fluid or

Yeah, somehow the accel rate got misconfigured and I had to redo
motor tuning. Deceleration on the Y axis was a little lower than the
X and Y couldnt keep up.Hence the odd rapid Z safe move to the
second set of pocketed arcs.
But I still have a problem where it plunges into the
material.... This is about half of the code attached, and
approximately where it
plunges diagnally into the stock. It's FANUC. MACH1 seems to
like it (or then again, maybe thats the problem, as Surfcam
FREE only comes
with a few PP)
The feed rate is slowed way down so I could pinpoint(somewhat) where
the problem occurs.
I've initially rewound the code in MACH1 and zero'd all axiis, then
I jog to X0 Y0 Z1 and start the code from there. The code will run
correctly throughout, with exception to where it crashes at the end
of the portion of code that Ive included.If I let it run from this
crash point,all the rest of the toolpaths are executed as they
should be, but the "real time display" in MACH1 clearly shows the
tool travel to X0 Y0 Z0 diagnally through the stock ,and then back
up to safe Z(1), then it executes right from there.

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.

Tim,
I would love to but its of a prototype that I've designed and
I'd
rather not take the chance of somebody stealing my idea before I
get
a chance to build it.
Would it help if I posted the first 10 lines or so?Because Im
guessing that's where the problem is. I just dont know enough
about
Code to pinpoint the problem.

Regards,
Jim

Re: Pre-wired drive unit

Robert Campbell
 

Ah-ha and a couple of others have plug and play units.

Building your own is not that hard. I could break out my cnc router plans
and give you all the information that you would need to build your own.

If the need is there, I could have a local company build several units.

Does anyone manufacture a pre-wired drive unit with geckodrives,
power supply, parallel plug etc ? I'd like to be able to just
plug
in the parallel cable and hook up the motors without a lot of
building.

Re: Drill press & cross-slide vice

JJ
 

Of you are intent on this approach you will find that cheap drill
presses not only have crappy bearings, but the spindle is not stiff.

The rack and pinion gear that drives the spindle is very very sloppy,
and there is no adjustment.
I pulled out my quill, drilled and tapped two 10-24 holes pointing
toward the quill, one from the front, one from the side. Inserted two
brass screws with nuts to lock them down, and reduced the play some. The
remaining slop comes from the quill spline fitting into the pulley at
the top.

JJ

Not at all. Membrane switches ARE momentary. The reason I wanted to use
membrane switches is that I figured they would be more oil and chip
resistant.

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.
The idea of of making my own did occur to me but I didn't think about it
all that much. Now that you mention it you could use some of the wide
flat PCB mount "tact" switches and just stick some kind of plastic
membrane over the top. Hmm, yeah, I think this could work!

Re: Keyboard wiring?

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.
