Ive never had any problems with stability, except when the part geometry was
bad to begin with--then, very rarely there will be an odd toolpath when in
cutter comp mode and without any alarm being generated.
Had several FADAL's that I worked with that constantly lost the ability to
receive or send data. Shutting down the machines and restarting them always
solved the problem. This occured at two shops I have worked at. I'd call
this a bug in the FADAL control.
The FADAL control has good ideas, Sam but it's development never got to the
point that FANUC or Haas have and now it's on to a new control with
all new problems.
www.cnczone.com ... the FADAL Forum that I requested and got when I
was working with FADAL's awhile back.
Never had this problem, unfailingly any problems as you describe have been
because of faulty cabling except once, where the comm port had gone bad in
the host computer.
I just can't condone the idea of selling "parameters" in order to "turn on
options"....so..Haas and Fanuc can kiss my ass......
And as far as operator interface, I still think the ole blue Milacron was
the bestest that was ever made.
I'm really not all that picky though...set em up, push the 'go button' and
with pretty much all of them they make parts....for one off I would
certainly prefer Fadal to Fanuc, and having no personal exp with Hass I
can't give any comparison.
As to the "round and round" you mention, there is only a set number of
menus, and they are ordered--in time, you memorize where they are so you
know beforehand how many times to press the space bar,etc to arrive at the
one you desire...though I admit, sometimes I might get in a hurry and go
past the one I wanted so will have to go another round...in this case, I
blame myself, not the controller--after all, I've been running that
controller for near 10 years now--I SHOULD be able to work the panel, no ???
There could be alot of causes for that. One that comes to mind is grounding.
Fadals "are" touchy about how they're grounded. An improperly grounded Fadal
can do all kinds of weird stuff.
Alot has to do with the firmware version as well. Like any other software,
it can have bugs. The version my machine was shipped with is solid as a
rock. Had the factory tech put in the latest spin about a year ago (free by
the way). After he left I started a part set up, punching up the same
utillities, and following a similar proceedure I've done a thousand times.
All of a sudden, the table took off in the X and slammed against the limit.
After I changed my underware, I put the old executive module back in. No
Kind of irresponsible on their part to even distribute something like that,
but that's the only incident I've experienced in 18 years of using them.
Grounding wasn't the problem.
FADAL's former distributor for Arizona (Magna Machinery) ailenated many
shops here and left a bad taste (lawsuit city) with several Phoenix area
You won't hear Neal talk about Magna or what is documented at:
www.cnczone.com in the FADAL Forum.
I stand by what I said:
There simply is no comparison between a Haas control and a FADAL control.
I'm not a big Haas fan but the Haas control is well though out, rock solid
and does not suffer from what FADAL's controls have a proven track record of
Many people are very loyal to FADAL because they view it as an
affordable machine that they have made money with and as a machine
that has given them the chance to start their own business.
While I do agree it's a more user friendly control than say a FANUC
I don't feel the FADAL control is in the same class as a Haas control
and it simply does not have the rock solid stability of a FANUC.
The control is just one aspect of a CNC machine. No one should
buy a CNC machine just based on the control.
I have posted many times what kind of machine I favor as an
affordable 2 1/2 axis production mill.... a used Matsuura with
either a Fanuc or a Yasnac control.... neither of which are
as good as the Haas control.
Does this make it easier or more difficult for you ? :>)
Sure but it doesn't have anything to do with stability.
Your point on pathetic documentation for a FANUC is certainly
a valid one.
FADAL should offer to refit an existing machine for what it cost them when
they properly develop their new control. Based on what is posted in
www.cnczone.com in the FADAL Forum and based on e-mail I have
recieved the new FADAL control has a long, long way to go.
Well, IIRC last we talked about BobCAD, I think you were going to get
version 19. BobCAD has many similarities to FADAL.... they both move on
before getting the bugs out of the older version and get the user to pay
again and again for what they already paid for. Have a good friend that I
work with that owns BobCAD version 19.... he's had enough.
I considered Haas......then there were a lot of Bridgeport vmc selling in
the mid 90's too...
I have the 94.1 version in two of our machines, and some sys99 ver in the
other, no stability problems with either of them
No exp with the newer Fadals though except what Ive been told by another
individual who has six of em...FWIW he wasnt been very happy with their
Funny thing....is...I actually LIKE the -4 fadal controller, and I wouldn't
buy a new Fadal BECAUSE of their newer controllers...
Buy an older linear way machine, rebuild the spindle, put new ways and
screws onto it and I'm good to go....
Bobcad likely isn't gonna get any more of my money, either.
Alternate perspectives are what make other people interesting. <g>
I would have to agree. In my experience our Fadal controls are less
stable than the Haas control. We have to restart our Fadals to recover
from a lock up more often than the Haas.
And the Haas has bugs that the Fadal doesn't have. We had the Haas
lock up due to using a specific feed rate when we were machining some
wheels. It was a repeatable fluke of a problem, but changing the
feedrate cured it. I've also had a tool unclip error code on the Haas
where I tool the sheet metal off the front of the machine and poked
around for awhile at the innards, I didn't really do anything and it
"healed" itself. It's done this twice, but it's been fine for about a
I think a lot of this is probably due to familiarity. You can't do a
mid-program start on a Haas at a tool change without the Haas
unnecessarily loading the prior tool. It's an easy fix though, just
start on the next line AFTER the tool change.
This is not a problem I personally encounter, since I do most all of my
editing from the CAM system.
I'm not sure what you mean here. Could you elaborate?
Stability wasn't what I was referring to when I said the Haas control
isn't all THAT much better than the Fadal control. I was referring to
setup features; setting tool length offsets on the Fadal is easier since
it allows you to input any setting gage size, and automatically puts the
next tool to be set in the spindle, the Haas doesn't. Fixture offset
setting with an edge finder is easier on a Fadal as they have special
feature to accommodate different dia. edge finders, which the Haas
As far as inputting programs by RS-232, our Fadals are very stable in
that regard. Our Haas burps about one out of 25 times and the program
has to be sent a second time. We use an in-house built switchboard type
of input devise.
BD seems to be the kind of guy who gets a fierce sense of elitism and pride
by doing things in a way he percieves to be difficult to others. He's been
arrogantly thumbing his nose at us lesser mortals with our "sissy" machines
and methods for years. Sorta like in some cultures, your not a man unless
you can drink two fiifths of whisky and screw ten women in one night.
Instead, your not a man unless you use a Fanuc control, and program in
command line APT. Takes all kinds I guess.
On the positive side, he's probably very good at what he does. On the flip
side, he's probably not much fun to work with.
