just added a button to my finished screen but it doesn't work...

also the screen at home has the same problem which is the standard not altered mach screen

perhaps a problem with the settings?

General Mach Discussion / not consistant behaviour

« on: March 12, 2010, 05:29:21 AM »

Dear all!

can't seem to get this right.

opening and closing goes smooth using the C axis with brain control.

but opening nor closing happens at the same location...

first, when C value is made 1 the relay should be triggered. but this only happens about 10mm after the C is opened.

not such a huge problem since we have a second delay on the pneumatic operated valve.

problem is, this doesn't always happen in the same location, especially from a different left and right cycle (as shown in the example code)

right side seems to open a bit sooner then the left side but then again sometimes it doesn't... this is different from day to day but also from hour to hour and very rare also from cycle to cycle...

My guess is that the PC isn't able to handle the signals

tell me what details you need...

Show"N"Tell ( Your Machines) / Fast sherline

« on: February 21, 2010, 03:19:20 PM »

Hey guys

will post some pics and vids when i get to it...
have installed 45W servos on the sherline mill at home

now, this makes things go fast (like i hoped  )

problem now is the leadscrews flying around like crazy... any ideas? has this been solved before?
have some ideas but thought i'd hear you guys out at first...

cheers

Show"N"Tell ( What you have made with your CNC machine.) / What i didn't make with my cnc machine

« on: February 12, 2010, 11:47:29 AM »

Perhaps a good idea for the disaster tourists among us...

come forward and don't be ashamed...

here's my latets one

Already made some adaptors for the 45W servo motor from cncdrive with the sherline and thought i'd give the last one on the stepperdrive...

forgot to tighten the bolt from the morse cone...

General Mach Discussion / Jerking with short segment G-code

« on: January 20, 2010, 05:17:30 AM »

Dear all

Have read all the topics about this and haven't come across the solution for my app.

Let me give you an idea about what i'm willing to accomplish:

I'm about to apply a coating on a round surface using the tangential option in Mach3.
I output the G-code using VX cadcam. because this to-be-coated surface has complex upper contours it appears that VX cannot output G2 or G3 segments (allthough it all looks like its round)
The resulting code is cut in to about 1mm pieces.

Problems so far

Without "tangential" turned on I get a rather smooth run apart from some bumps here and there...
When I turn on "Tangential" the whole Machine starts to shake like it's dancing the samba!

checked speeds and accelerations, all set to a high enough value... according to all the topics i read everything should be OK.

any ideas?

i'll add the example code for reference...

The XML will be for later on when i get the chance to download it.

PoKeys / Best way to program pokeys in mach3

« on: December 07, 2009, 06:58:37 AM »

For the moment I connected the pokeys to mach3 using some brains.
This brains consist of an OEMLED2002... connected to a desired function

Is it better to connect the OEMLED from the pokeys to an OEMtrigger in mach and use this trigger for further programming?
seen this typ of programming in Hood's pendant and it made me wander.

Reason for all this is that the pokeys seems to crash my machines, have 3 identical machines running it and all 3 were crashing.
Disconnected to pokeys and all was ok.

Cheers

Video P*r*o*b*i*n*g / moving axis with captured pictures or video

« on: October 28, 2009, 02:58:19 PM »

Dear all

is there a way to capture a picture from the webcam, find some structures on it that you need, add coordinates and tell mach3 to go to that coordinate?

how to find the structures isn't the issue, problem is linking this with mach3...

thanks

General Mach Discussion / Mach3 and stopping

« on: September 28, 2009, 05:00:01 AM »

Dear all

Having a little problem with mach3.

sometimes mach3 just stalls, losing several steps while doing it altough the steppermotors stop in an instant.
There are no led's flashing nothing. Just a stop at a random place.

Do have a Pokeys hooked up to the machine but the stop button has several other funstions hooked up trough a brain so if there was some interference these functions would also be activated.

When the machine has stopped it can be easily started again with the start button but several steps are gone.

Second problem is that when i do hit the stop button it also loses some steps... perhaps this is related to the 4000mm/min i'm running?
there are no milling forces because i'm not milling, just dispencing silicone.


anyone? just let me know if you need additional information.

Brains Development / marco or userbutton from brain

« on: July 16, 2009, 06:20:27 AM »

found this but don't really understand...

Set Trigger Macro using “Push User Button” in Brians:

First, you dont put the code in a button, you put it in a macro file. For
example file: m600.m1s
SetMessage( "This is a macro call..")

Then , you have to set that macro to be the default macro call with a call to
SetTriggerMacro( 600 ) at some point in the program, an init string could do
that if the SetTriggerMacro call were in another macro file that is called on
startup.  Then the brain will execute m600 whenever that brain termination code is
called.

someone???

Brains Development / brain to send c axis from 0 to 1 and back

« on: July 13, 2009, 04:54:23 AM »

Hi

Now that i worked out the issue with the M7 function i need a way to activate my output trough a button.

button is hooked up to a pokeys.

so OEMLED2002 needs to make the c-axis 0 when pressed and 1 when released...

Can anyone help me with that?

Thanks in advance.
