General Mach Discussion / Re: Mach Controlled DIY embroidery Machine

« on: January 20, 2010, 12:51:36 AM »

Finally i am in position to post some pictures of hardware of my Embroidery Machine... Their are 04 major parts in the hardware:
1- Sewing Machine Support Structure (MDF and Wood)
2- X/Y- Carriage ( Mostly Aluminum , few parts CS)
3- My Controller Box
4- Sewing Machine

Day before Yesterday, I completed The X/Y- Carriage and Yesterday my complete day spent on the controller box..This time i am using PIC based controller... Actually, The Controller box got damaged during Flight.. The Transformer Loosen and left it place from the foundation screws and rolled over on the Modular Cards.. I have removed the broken/damaged components and now it has to be checked for integrity...

The sewing Machine Wheel is removed and some components/Linkages were disabled for embroidery work..

Dear fellows,
Happy New Year and Marry Christmas... No , i wrongly said.... " Marry christmas and Happy New Year"..Now that is right.. About 6-days difference Christmas came first..

Hi girls and Womens of the Forum, And the guys and gentlemen who loves embroidery work like me... Last year My wife stressed me to make a DIY embroidery machine with bigger Hoop and that can do all type of stitch work... .. It was a challenge to me... .. All types of stitches!!!!.. I asked her What do you mean by All type of stitches???...

She replied " I need a machine that can compete with modern industrial Machines"... Hmmm..... and the story Begins...and I left Woodwork and tried to look like a embroider..From that day and now, i have a lot of knowledge about embroidery machines and working principal...

I researched on the machines and found that The Following are the few File Formates that Embroidery machine uses..
Brother *.pes
Tajima *.dst
Viking *.hus
Melco *.exp etc

From that day, After a long long time i was able to make a software that can drive my CNC Embroidery Machine with all types of stitches that industrial machines can do. Basically, my intent was to convert low-cost manual sewing machine into embroidery machine that can compete with industrial machines. For this I have to write a software that can convert the DST file into machine readable file.. The DST file is a TAJIMA file format and it is complex binary coded...It was hard for me make a software that can read the file and simulate the design and make the Gcode..Previous experience in visual basic Programming made it possible to write a customised program...

Following is the software that i have written in Visual BAsic Language.. With my this software machine will able to do Straight stitch, Cross-stitch, Zig-zag stitch, Satin stitch, Tatami stitch,chain stitch, Motif-run stitch, triple run stitch, Contour stitch, Perpendicular coil stitch and all types of Alphabets and Pictures...

For hardware drawings are completed and 80% will be assembled within this week end. The functionality of the machine will be..

1- The Large Hoop working area ( 9" x 20")

2- For every new colour in design machine will stop with needle upward condition for colour change.

3- A bulb will lit up so that thread can be easily changed

4- Automatic thread cutting

5-If thread broke machine will stop

further functionalities can be added in future.


Regards

Khalid

General Mach Discussion / Question to all having Rotary Axis

« on: January 10, 2010, 10:39:04 PM »

Hi Guys... I have a question... I want to rotate my rotary axis one revolution only after each X/Y move.. Like following

G01 X1 Y1
G01 A360
G01 X2 Y2
G01 A360
.
.
.

Now I want to rotate the A-axis in only one Direction Suppose CLOCKWISE ONLY...
Now i need some explaination for the following?

ROT 360 ROLLOVER - when checked the A axis Dro wll display from 0-360 degrees and then start over at 0.
If not checked the A axis DRO will be additive such that 2 revolutions will display 720 degrees.


In the above, If i give command A360, will it rotate one revolution and become '0'..If yes then this will do my work!!!

ANG SHORT  ROT ON G0-The axis will move in the shortest possible move to a new position, such that if
at 0 degrees and you jogged to 359 deg then it would just rotate   -1 degree.


In Last, Is it possible that the A axis DRO itself become '0' when one rotation of A-axis complete? So that it will prepare for next 360 revolution?

Reference to following thread at CNCZone
http://www.cnczone.com/forums/showthread.php?t=10369

In the above thread a link is given for Mach3Beta7.61.exe... Can someone help me finding this... I want this Beta version because it has capability of Running all the three axis in harmony of one axis you want to run.

Thanks and appreciation for help.

General Mach Discussion / Re: Idea for CNC Mach controlled Quilting Machine (No costly stitch regulator)

« on: December 13, 2009, 01:47:24 AM »

KOKO..Thank you for your feedback on this...

Now what i understand is to install an ENCODER ( can i use encoder from a Mouse) on sewing Machine Wheel .. Now I just want some more HELP.. As RC posted his comments
"configure the encoder to Mach as a pendant MPG and run the G-code in Shuttle Mode by simply pressing the treadle to control the speed"

I have few questions:
1- How many encoders are required? Where the wires from  the  encoder will be connected to?..Can i use Breakoutboard to connect the wires?
3- How can I configure the encoder to Mach as a pendant MPG?
4- Do I need EXTERNAL HARDWARE for MPG i.e.Knob or I can use the Mach3 MPG ( software based)..

Dear Ray,
Kindly guide me what Hardware i shall require?.. and what is SSO?.. Also please tell me Can i use ARDUINO in this project...
Following is Arduino Specification...
http://arduino.cc/en/Guide/Introduction

It can drive Servo, Stepper and DC Motor ..A good amount of Analog input Pin/and Out put pins..It also has digital input output pins..

Ray Thanks for coming back and insight... I will difinitly study all that stuff i never did before and implement for this purpose..However with your help it seems not difficult... I hope you will keep brain storming and will guide all of us to the path of success..

Best Regards

Hi RC and Koko again:)

Thanks for brainstorming... Is it possible to complete automation of the system without human intervention...I didn't used the pendant stuff nor i ran my machine ever on shuttle mode..but i will study it too..Last night i studied Mach3Turn manual and Mach3manual but i find no clue How can we synchronise the two inputs from X/Y carriages encoder to get a single Velocity vector suggested by RAY..

However when i studied about MPG pendant and Shuttle pro i found that this will again require a human to stand by the machine and it will be difficult for a human to control the regulaerity of stitch length..Am I right? Somewhere at CNC Zone i studied about the Pendant and Shuttle Pro capability of Mach3

I really like this one. Run a program, during the run press the Shuttle
Button. The program will ramp to a stop (Deceleration time may be set int he
config/state screen). Now turn your MPG, the tool will move with your
turning of the wheel and execute the program slowly. Once your past the
feature you were nervous about, hit the shuttle button again and the program
will ramp back up to speed and continue. You may only go forward, but I did
allow you to turn the wheel in either direction just in case your right hand
gets tired playing with this feature. (It is VERY cool, I can see why this
is popular, and have no doubt it will be popular in Mach3...).
Whatever JOG mode you are in will switch to MPG mode when you press
shuttle, but it will revert back to what you had selected when you exit
shuttle mode. Please let me know what you think of not only the way it
works, but how well it works for you. Small tweaking may be necessary on my
part. (Though my mill and I love it.. )"

If i use Pendant for Mach and run it in shuttle mode, then If i have to use my hand to control the speed at each bend/corner of the design Gcode then it will be difficult to automate ...

I will be happy if you all can help me in this matter.. I have started the making of machine and it will take less than a week to be opera
