Re: Speed control RC servo control of DC spindle

 

Nattyone960 thank you for bring this up. Can you or someone else
explain to me the difference between an inrunner and an outrunner?
Which would be best for a spindle?

Re: Mach 3 spindle

I verified both of your suggestions Art (step/dir selected, and laser
mode not selected). Still no spindle, but everything else is fine so
far. I keep checking back in M2 and all is well there. Would a
screenshot of some config screens help? What about a re-load of M3 -
does that make any sense?

Thanks again.......

Re: User Button activation from an input

 


Two possible routes:

(a1) Set the input to be an OEM trigger with code 301

(a2) Use the SetTriggerMacro in your initialisation to link all
buttons with 301 into a given macro (say M991.m1s)

(a3) In this macro put the code you want your button to execute.

or

(b1) Inspect the input with a IsActive(ss) call in a Macropump and
if
so do your own code.

(a) is messy because of all the steps setting it up and the fact
that
the macro needs to find which input caused it to run (if you have
several. (b) is messy because you usually have to notice changes
of
the input as you will not want to run the code everytime the
Macropump runs - only when the button goes down (or sometimes up)

Have a look at section 4.2 of



for the OEM trigger technique and



for the Macropump. Bot relate to inputs via ModIO but there is
nothing special other than defining the input port as 0 rather
than 1
or 2.

Let me know if you need more detailed pointers

John Prentice
John: Thanks. I read and posted to Art's response and then read
yours. I'll have a look at both your approaches. I just assumed
there would be a easy way to run custom buttons you can
write....silly me!!
Re: User Button activation from an input

 

--- In mach1mach2cnc@..., art <fenerty@...> wrote:

Hi Tom:

Sorry, I meant to respond to this earlier. You need the
SetMacroTrigger()
script call. Calling a user script is a bit of a kludge. You call
SetTriggerMacro( MacroNumber) , the macronumber is the file number
like
m666.m1s woudl be SetTriggerMacro( 666 );

Then you use OEMTrigger on function #301 to actiavate that file.
The
SetMacroTrigger must be called before the OEMTrigger on function
301 will
work.

(Im thinking of a new way to do that which is easier, but its a
bit of a
bitch to get user buttons, they dont exist till the program is
fully
iniitialised..)

Thanks,

Can I assume that the above process is limited to one custom button?
I don't know if it would work but having a stored parameter for a
button such as ID # that could be assigned in the item details so a
direct call would activate the button would be nice from the outside
world. If user buttons are dynamic objects then it could be a
challenge on your part. There is always the nightmare of assigning
the same number to multiple buttons (like duplicate IP addresses)
and REALLY confuse things (:-)

Would it be easier to just call a specific Macro directly from the
input? If so what would the syntax look like for a call from a port
pin activation to a macro?

Re: Slow computer

 

Spent some time yesterday playing with a TaigCNC machine and comparing
Mach3 with the DOS package that normally drives it. The original control
program is running on an old machine that would probably not even load
W2k so I had taken along an ITX box with W2k already installed. Only
problem is that it is an 800MHz C3 processor, but since this is intended
to be an embedded computer to go with the machine nothing else was
installed on it.

Operation from the DOS program is smooth and clean, but running the same
tests in Mach3 give a number of problems. Even slowing things down,
running just 25kHz and slower feed rates we have a decided 'pattern' to
the noise from the stepper, like something is sticking every couple of
seconds, while the DOS has none even at a faster rate.
I've also got a Taig machine, and have a similar effect from the PC I built to run it...
The steppers "stutter" slightly, causing them to stall very easily.
I have a distinct jump in the timing on the driver test wave form - *something* is interrupting the pulse train.
In my case also, there is nothing else running - I don't have a floppy drive, so I can't run the DOS controller as a test.
(The motors run nice and smooth with the DOS program on an old 333 MHz PC, however.)
I suspect a motherboard chip set incompatibility somewhere... It's got me (and Art) baffled.
I tried it with & without a 5v output breakout board, with & without HT enabled, with & without the network adapter enabled, with & without the integrated video adapter ... nothing made any difference, for better or worse.

I posted a message here on 5/22 with all the technical details, if you're interested in them. (Subject: Stuttering motors)

I've ended up ordering a Dell Dimension 1100 to run the mill (~$300 w/o monitor) & will use the custom built machine for Cad & other power-hungry app's.
Running the driver test on another new Dell 1100 (fully loaded - virus scanner, firewall, network adapter on "auto", integrated video, the works) gave a flat test wave form, so that should certainly workwith a stripped down setup.

Re: powermax 1000 machine interface connector

 

Gents

I bought a connector for the Powermax 1000 machine interface and have it installed. Just thought I'd
pass on the part numbers that I used. Per my previous posting, I was not sure I had the proper part number for
the plasma interface but now have them installed to the THC SENSOR card inside my Powermax.

The mating (male pinned connector) seems to be an:

Amp/Tyco 14 pin part 26044-1 or (DigiKey Part A1358-ND)
Male pins( 5ea.) I used were: Amp/Tyco 66099-4 or (DigiKey Part A1340-ND) and will take 16-18awg wire
The matching Size 17 cable clamp for the exiting wires is Amp/Tyco 206070-1 or (DigiKey Part A1332-ND)


Should you need the existing connector:
The square flanged Connector on the back of the Supply is Amp/Tyco 206043-1 or (Digi-Key Part A1362-ND)
The female pins for this connector I have are Amp/Tyco 66101-4 or (Digi-Key Part A16080-ND)

These pins are 30u Gold over 50u Nickel crimp style pins and sockets.

I've uploaded 2 photos showing the connector I've added and The Connection to the THC sensor board that's mounted
nearby inside the Supply. I hope they made it to the proper location.

That's the part number I landed on, but never bought one. I ended up

Re: RC servo signal - R/C brushless / brushed spindle motor speed controller

 

Hi Hugh,

Thanks for your reply. You have answered al my questions.

Many years ago when I was playing around with RC cars, the Speed controller I used was an OS 19 motor. Messier than an EMC but a lot of fun mechanically. :-) It was what got me into machining in the first place.

I built the 1/8 scale car from scratch. I used a PCB for the chassis to provide the suspension.

Ah, the memories.

Cheers,

Peter.

The transmitters can be set either way to match up with the speed controller. I have never seen a standard published so you should probabbly design for either.
Some do not have reverse and use the full span for forward, most are adjustable by using the ESC programing function built into most of the new ones.

Every speed controller I have tested or serviced has SUPPLIED 5 - 6 volts on the +5 wire to run the receiver and other servos. This feature is called a BEC (Battery Elimnator Circut). Amp capacity ranges up to 1 amp on some of the new ESCs.
You do not need to (you may damage the ESC or BEC circut if you do) provide 5 volts to the ESC on the control cable just ground and the standard control signal.
On our bench testers (my design, not commercially available) at work (we own a large hobby shop that does lots of repair work) I installed a separate lead for testing ESC's that does not provide 5 volts but instead applies a variable load and displays the BEC output voltage.
Servo output pulse is a standard 5 volt pulse of 1 - 2 MS occuring every 16 MS.

Hi Manu:

If setting the scope to 2ms shows the right signal, and otrher setting do
not, then the scope is confusing you a bit. (Mach's not going to change the
signal based on the scope setting..:) )
So it sounds liek you need a 25ms base PWM freq. So set it to 40hz. That
at least will bring it in line. RC SErvos can be picky I thnk about the
signal they recieve, the PWM is not really designed for them, all you can
really do is experiment to see what the effect is. Hopefully youll find some
setting of that which is usefull..

Re: Just upgrade mach, no job screen dispay coming up.

 

Art,

I have tried the 1024.set and it comes out fine. You also said to check that the toolpath display box was checked, I have done that and it still makes no difference.

Should I download the screen .set from bob campbell and try it again? Maybe I should try one of caudlets screens?

Precision Gearheads

Hello All,

I purchased 2 CGI Precision gearboxes, a while ago and probably
will never get to the project I had in mind for them so I am offering
them up for sale to a good home. The gearboxes are NEMA 23 frame,
22:1 ratio. The model # is: 023PNX0220-XX-23N08. The gearboxes cost
over $600 each new. I am willing to let them go for $450 each. If
you are interested please email me: casey@... Thanks.

Casey

The zero part offset button works on the Lathe screen that comes with
Mach, but on my modded screen I can't get the damn thing to work, I only
copied the buttons from the original to my screen :-( All it does is
zero the DRO's...

all input appreciated
Steve
