Different use of Mach3
« on: October 23, 2006, 06:47:43 AM »
Hi! from Greece...
First of All sorry for bad My English.

I m 35 years old
Job: Art Director SonyBmg Greece

I m An expert on Graphic Arts so if you have any Q about Print, Colour theory, Photoshop, QuarkXress, Adobe Illustrator you can ask anytime....

Some links to see the Use Of My Table
I want to build A CNC machine to use it for doming decals
You can see this video: http://www.color-dec.com/doming500W.mov
Or some information Here

I want to build A XYZ machine for doming scripting
Doming Scripting
Applying a clear doming material
(urethane & epoxy) to the surface of labels, nameplates or decals for the purpose of creating a clear raised (?domed?) surface. Used to enhance and protect the appearance of these products.
Scripting: An automated doming process using XYZ motion to traverse scripted products.

I Almost finished the hydraulic part a precision metering system for two component.
I have to mix in Ratio 1:1 two parts and the mixed fluid has to be applied under (0.5 -1 bar) pressure on decals or stickers by the dispense valve.

I design a table for this job

I think to buy from http://www.lowcostcncretrofits.com the 5Axis Servo controller.
and use the mach3 to control the motion.

The Question is :
Is that possible to make this motion

Or look at the video

As you can see  The Z
Goes down then
the valve is open then
run the X Y path then
Stop the Valve then
The Z  goes up

and loop to the next path

Is that possible with mach 3

i will buy the mach 3 but only if it possible to make this kind of motion :'( :'( :'(

 sorry again for bad My English

Please if you know or you have an idea answer me...! :)

Well it seams reasonable but you can download Mach3 for free and give it a try.

give it a try.
I have not finish the table yet... :'(
I can't test it....!

I want to know from people which the mach3 is familiar and well knowed to give me an answer for sure...!  ;)
I think this motion is like to drill holes.... ::)

I watched the video. Yes Mach 3 can control the axis to duplicate these motions. You will have to generate the G-code. I think Mach has a code generating program called Lazycam that you could use for this. ( I'm not sure, I haven't had time to try it yet.) I use Artcam. You may want to look at it also. I think it would be right up your alley. You can download Mach and simulate a run without the machine. The free download will run 1000 lines of code before lockout. I may be wrong, but to simulate I think you will have to install drivers also. If you don't already have a dedicated PC for this, back up your whole system first. I think Mach takes almost complete control when it comes up. This can do funny things.
;D If you could see the things I have in my head, you would be laughing too. ;D

My guard dog is not what you need to worry about!

As Chaoticone has said you can run Mach without a machine connected. I have Mach on three computers, one is hooked up to my mill the other two I just use for testing purposes. You dont even need to set anything up apart from maybe the estop setting in" ports and pins",you may have to change the active low setting if you keep getting the flashing reset button and cant stop it flashing. You can leave all the other settings as standard or you can set up motor tuning etc to give simulated speeds that you think you will have on the real machine. You can then test to your hearts content :)
 BTW from what I see on the video that will be a piece of cake for Mach, just give it the code and it will control your motors.

BTW Mach does take good control of the system and although it is best to have it on a dedicated machine for control I have done all sorts of things like CAD, CAM, Image editing etc while Mach was actually running my mill. This is not really advisable but I was just testing things out and it behaved beautifully :D

Here in Greece often we said that " the difficult is to start up with something but when I start up nobody stop me"
I use Computers for the last 15 years and i m an expert in my job. that is becouse Before many year i didnot afraid to ask even silly thinks.... Of course I was lucky becouse I learn from experts and people who did not have any problem to give me a help in my first steps.

All I want to say is that (sorry but my English dont help me)

I will ask you a lot of thing that I dont Understand  :D :D :D :D :D :D :D :D

For examble....

1) Can we stop the motion of the Z axis when it is down and then give motion to the 4th motor (which opens & close my Valve) for specific time. Lets say 1.5 Sec This is the time I need to open the valve drop 0.5ml and close the valve)??? ??? ??? ???

2) I will buy 4 600oz servo motors . The 600 Oz power is enough to move the Z head (With my valve is about 10-15 kgr).

3) If I give you very small patern of decals  this

I want to Go to center of every Decal

Z down
open the valve ( lets say that the valve opens R3.25 and close R0)
Close the Valve
and then the Z go to 3cm up
And then move to next decal...

If I see A code once i really I understund a lot of the G code logic.

If I ask A lot tell me and I stop.!

And A tip from me to you (;D:D :D :D :D
I work In Adobe Illustrator
After some tests I understund that The DXF format isnt right for Mach3 I have to open it from Corel And Save it again. Then the Mach3 can read the DXF file.

Thanx Anyway for your replys.... I really like it...!

I think I understand what you are wanting and I am sure MACH can do that. If I understand correct you can use an output to open and close the valve and then all you will need is to control the three motors. All axis in Mach can be controlled at the same time and idependantly of eaxh other.
 You could for example use a solenoid valve on the Z Axis liquid despenser and set it up  as the coolant in Mach, then a M8 in your code would open the valve and a M9 would close it.
 Hope I am understanding you correctly

There is a code that will pause the machine for a specified amount of time. I think it is M00, but I don't use it so I don't know if that is correct or not. This type of code will not be a problem for Mach to perform.

G4 is for dwell (pause) and you can specify the amount of time to dwell by putting a P*** (where *** is the time)
 So as an example if your code was 
G1 Z-3 F100
G4 P3
G1 Z3
 The Z Axis would move to -3 at a speed of 20mm/min then pause at that point for 3 seconds then raise up to Z 3.

If however you were wanting to move the x and Y axis but leave the z in the down posiytion you would not need the dwell line, all you would need to do is move the x and y to your position, lower the z then move the x and y to wherever you  want then raise the z then move on to your next position and repeat.
