I know this must sound dumb, but aperantly I locked the settings. I
am not able to change any of the settings. I assume that that is
the function of the Lock menu item. When I click unlock, it asks
for a password. I have tried many, but nothing will "unlock" it. I
seem to remember that at one pount I clicked lock. I also seem to
remember something asking me what I wanted the password to be. I
think it said "none", and then I clicked the X thinking it would
cancel it out. I have tried NONE, none, as well as blank spaces,
but they don't work. Is there any reset password function?

Thanks in advance for your help!!!

Hi Derek,

Are you using the quill for the Z axis?

Brian:

Can you give me a snippet as a test. For example I just did the following
test.

G0X100A10
G0X0A0

I set the X accel at max, the A at very slow accel.

When I start it , it slowly accelerates then decelerates to an X of 100, A
of 10, the it accelerates and decelerates ending at zero.
Does yours pass this test as well??

config there is a checkbox to turn on the angualr decrimination.

This when

set to 91 degree's will force the angualr change to be done in

and most aother moves to be done in CV. This shoudl solve the

trouble. The

angualr number of 91 is put in the corrections tab under Blend

Art I fear this is not the case I have tested in EXACT stop and In CV
modes. the problem is that you are missing an accel. some where?? I
set the Accel. VERY low and it is not putting the motor throught the
accel curve every time. When I start the porgram it will move with
out the curve (it uses one from I don't know where) that I had set
then it goes in to a other move and uses the accel ??? I don't get
it at all... I am going to test the other axis and see if I get the
same problem.

I tested the B axis and I have the sam problem... I think I see what
is going on. The Rot. axis work GREAT if it is the only axis moving
but in a multi axis move I am having trouble. the acceleration of the
A xis is not setting the rate of accel. I hope this sheds some light.

Thank you

Hi:

My problem might be my frequency timer. I've got Mach2 set to

25,000 khz, but my timer likes to stick around 8000 - 9000 khz while
on the diagnostics page within Mach2 itself. When I run the OCX
tester, it seems to jump around in the 100,000 to 500,000 range, is
that even possible?

No, its not. This is probably the root of the trouble. This isn't a laptop
is it? If not, then try killing every application and process you can. You
HAVE to get those numbers stable before bothering to test further....

Don't panic too much over this one, I think lockdown for 4.0 is more

important and that is now so close I can smell

Yes, lockdown of Version 4.0 is getting very close. Actual bugs are almost
non-existant. Not to say they don't exist, but as a comparison I think 4.0
is a world better than 2.0 at present. ...

Hello Art,
Thanks for the reply, it means alot to have help available for
this stuff.

It certainly 'appears' that there is some micro stepping taking
place. Using a 1 to 1 drive, and .0625" lead (16 revs per inch), I
required approximately 48000-50000 pulses per inch to get close to a
full single revolution of the motor shaft (.0625" move). That
calculates to around 15x micro step (200 pulses per rev X 16
revolutions = 3200 x 15 = 48000 ppi). Again, I've no means to mount
the motors yet, so there is still no load on the motors.

This is seeming VERY unlikely to me. I could have sworn that the
control was full step. When i used Master 5 and Win98 in the past, on
a small lathe with a 24 pitch lead screw, I used 4800 ppi (200 x 24 =
4800) and had excellent results concerning accuracy over a 1" move.
The only thing that has changed since then is the OS, WinXP and Mach2
of course. It seems likely that I'm loosing tons of steps, rather
than running in a micro step mode.

My problem might be my frequency timer. I've got Mach2 set to
25,000 khz, but my timer likes to stick around 8000 - 9000 khz while
on the diagnostics page within Mach2 itself. When I run the OCX
tester, it seems to jump around in the 100,000 to 500,000 range, is
that even possible?

I did install the special driver to get Mach2 to even run. My
board is an Abit KX7-333RAID (VIA KT333 chipset), and yes I do have a
RAID 0 array on this machine, as well as a network card and a cable
modem. The BIOS says it has an APIC mode, but it is currently
disabled. Also, I have no Virus scanners, or any other programs that
load with WinXP. I do have a few system services running that I'm
sure I don't need (around 18 processes including IE), but I don't
really know what I need and what I don't.

Thanks again for any help.

Hi:

Lets take these one at a time...

>

I got my steppers to work with Mach2, but I'm having
dificulty 'tuning' them for speed and distance (accuracy). The
motors are 1.8 deg/step, so thats 200 steps per rev. With a
leadscrew pitch of .0625 (1/16"), then my steps per unit (inch)
should be 200 X 16 = 3200 right?? My motors' shaft only turns a

tiny

bit (~30 degrees) on a .0625" MDI move. If my math is correct,

the

motor should turn a full revolution to get .0625" assuming a 1 to

1

direct drive of the leadscrew and 16 revs for a 1.000" move.

What am

I doing wrong?

You must be using microstep drivers of some sort. Perhaps 10

uStep woudl

explain it. Then it woudl be 2000 * 16 = 32000 / inch/ This would

also

explain the 30 (36?) degree movement for 1/16".

During velocity tuning it seems that the motors stutter a bit

(no

load, just sitting on the bench) at high and at very slow speeds.

Its not good to tune motors with no load. Some drivers will

jitter without

a damping force of some sort..

> believe stepper speed is directly relative to Voltage (of which

I'm

definitely lacking). However, I'm not sure if I'm seeing lost

steps,

or if there is a timing/signal problem keeping the motion from

being

smooth and consistent. This could easily be a problem with my
drives/lack of voltage, but was curious if varying frequency

timings

could cause this, see next question.

Yes, next question probably explains it..

I'm also curious about the frequency settings 25,000 khz,

45,000

khz etc... Considering my low performance stepper system, but

fast

1.73Ghz CPU, what frequency should I be using? How do these
frequencies affect steppers max velocity, loosing steps/stalling
etc...? Or are the faster frequencies only for running high
performance systems capable of 100+ IPM??

35K and 45K modes are used by people who need higher speeds. In

other

words , when they tune, the velocity is maxed and they'd like more.
Generally, unless your velocity is Maxed when tuning, stay at

25Khz, its

less of a drain on the Windows system.

Also, I noticed at

25,000khz the OCX driver test shows wildly varying numbers, mostly
much lower than 25,000khz. Do I have a Windows/motherboard/Mach2
driver problem or something or is this normal?

How wildly?? Generally, you should be around 25000, but only vary

as much

as a hundred or so. If its going from 20,000 to 25000 for example,

this is

too wild a swing and somethign is interfering.. This type of swing

would

generally be an application, or a network card interrupting too

much. Let me

know the swing your getting, it may point us somewhere...

Thanks,
Art

Hi John:

It crankes up to 77,000PPS wow! but is it real or is the

display just totaly screwed up? Art I tried the apic version setting
in bios nothing happened. But if the computer is busy doing something
PPS seams to jump right up there?

This is a DMA problem. Mach2 counts the actual interrupts as they occur
and the pulse/second number tracks the interrupts that occur in "count" CPU
clocks. So on a 1Ghz machine, Mach2 counts how many interrupts occured in 1
billion counts of the CPU clocks. When a system performs a DMA cycle, the
clock on the CPU CAN be disabled as thge CPU is shutdown during DMA time.
This means if you get way too much DMA, Mach2 dutifully did all the
interrupts it could, then found that 75000 interrupts occured in 1 billion
CPU clocks. Probelm being that usually 1 billion clocks took 1 second, but
in your case, 1 billion clocks took 2 seconds ( or 3 ). Somethign is eating
DMA cycles like crazy, this is usually caused by on-board video or a disk
caching scheme gone nuts. Look for some reason that DMA would be high, this
is just about the only thing that can cause the pulse count to jump high up.
This is most common on laptops which keep DMA'ing for a drive or video
cache...

Good luck,

Hi:

When I move the Z axis it seems

to over shoot by .010" and then slowly returns to where it is
supposed to be. The DRO readouts don't relect this change. If I use
the incremental jog and make a move as little as .0005 it still over
shoots by .010 I`ve tried messing around with the adjustments on
the rutex drive but I cant seem to get it to make any difference. Is
it possible I need to make an adjustment at the servo amp itself?
I'm not loosing any position on the axis.

This sounds like either a P setting or a setting in the servo amp. What
your seeing is following error which is correcting slowly. You need more
gain I think...

the obvious concern is 'legacy' issues I guess?

Don't panic too much over this one, I think lockdown for 4.0 is more
important and that is now so close I can smell it. I think maybe after that,
the next testing series could include it ?

I can imagine that it will need a small transition period for people to move
their macros over to a directory structure rather than using .m1s, .t1s ..
but long term I htink it is the right answer to these issues. It will be
especially useful to OEMs I guess with their own custom macro sets.

Whatever, It will certainly help me anyway ... I hope it will help others too.

Derek:

Yes, thats it. I neglected to put in a way to allow for a new Printer
port address. Open Mach2 and select the Rutex.xml file as the profile. Then
change the Printer port address to your port address. Then shutdown the
program and run Rutex then. It will then work... I will be adding an address
selector for the next release..
