Freescanning Rig

[Khalid Khattak]

Here is the description and specification of the above relay..

Here is the schematic...

Hi,

there is still a free pin of the Arduino passed through the board: Arduino digital Pin 2. There a single soldering hole beside the pin 2

@ GND: the row of holes between the +5 row (where you added the two clamps) and the analog pin row is ground as well as the middle clamps at the motor outs.

[Khalid Khattak]

Thank You very much Gunter...... Can you kindly tell me should i have install any protection diode..and if yes where? For ground you mean i can either solder the ground wire to the +5V ground (the row gnd where i added +5Volt ) or i can simply plug the Ground wire from Relay to the M1/M2 ground output connector..!!!..Sorry for asking too much questions...

Thanks for helping me...

[MagWeb]

Hi,

it doesn´t matter if you use the ground on pos1 or pos2 - it's the same "common ground"

yes you found the free pin2 (BTW my code doesn´t use that pin - You will have to activate it using the Arduino software)

@protection diode - I never used such a relais and I´m no master of electronics - maybe Walter can help?

[Khalid Khattak]

Thanks Gunter.. I think you are running the Cold Cathode Lamp directly from Motor Output..I wonder what is the wattage of your Cold Cathode Lamp.. I scaavanged some cold cathode lamp from Flatbed scanner and installed it at M2 and used your code..But the light was not enough...

So i have to do digitalwrite(2, High) and Low stuff...
I am thankful for your helping me patiently..

PS:
I have installed the diode at Relay...I will try it today and will show you my results... I am using 9Watt energy saver with chinese holder that convert 12V DC to 220AC to drive the energy saver,...

[Khalid Khattak]

My Arduino and Adafruit still survive my experimentation..But On this survival of my electronics is not due to me but all the credit goes to Mr.Gunter who help me and guided me on the right track.. I am also thankful to all the forum members including Greg, Walter, Ray and all the remaining fellows... Following is two videos of my working setup.. I hope now i will move to the next challenge that is Stepper and viper gears setup...

Sorry for my bad English in the videos ...

I have connected the Stepper Motor to 1:60 ratio viper gear box..Meanwhile my SN755410 IC's are shipped and within days i will receive them..
currently working on CNCieng the Quilting machine and devising the way to make a cruise controller using Arduino..This cruise controller will control the length of stitch when X/Y carriages are moving with a Gcode..

Hi mr. Khattak! It'snice to see your progress on this project. I'm just wondering where do you need these SN755410 IC's?
I'm not so expirienced on electronics too... but still my arduano is ready and waiting for gears and stuff.

So please enlighten me!

[Khalid Khattak]

I will replace L293D IC on Adafruit shield with SN75410 because L293D can only handle upto 600mA, whereas SN75410 does upto 1Amp...

[joshuaweiss]

It's for your motor, ok.
I'm waiting for steppers and gears for now.

Keep on posting Khalid, thank you for asking so many questions.

Yesterday I was disappointed with the above gearbox of viper motor.. My motor is 100 steps/revolution and the output from the gearbox is very coarse...I am running the motor with INTERLEAVE mode in Arduino adafruit shield and i am disappointed...
I will look further to geardown..need more help and suggestions..
regards

Hi,
I have made a rig similar to magweb and using his sketch StepDAV_06 http://www.david-laserscanner.com/forum/viewtopic.php?f=6&t=1216&start=15all works fine apart from learning to calibrate the camera.
I am slowly getting on top of getting consistent Reference scans.
I decided to try the sketch by jantje davidTrialV06 http://www.david-laserscanner.com/forum/viewtopic.php?f=6&t=1216&start=30but it wont work for me. I have made the following changes

const int StepperPort =1; //The port your stepper is connected to
const int LaserMotor =4; //The port your laser is connected to
const int LightMotor =3; //The port the light is connected to

The Laser and stepper do the up/down thing in the Arduino Serial Monitor when i send a 'U'.
The Laser will light up when i send a 'S'.
Light not connected.

When i start David and start a scan i get the following message in the Debug window

COM: Received message recieved M
COM: Message recieved M not understood.
COM: Sending Message M

Any idea of what i am doing wrong?

Hi velvetpig
Can you copy the code for the arduino you are using (or provide a direct link). Because when I look at the code I have just downloaded from the forum I do not understand how the program can generate the output you are giving.
Best regards.

Thanks for your time jantje,

I have probably done something stupid and cant see it
Hope you can help.
