Problems getting the software running about pwdr-model-0.1 HOT 13 CLOSED

The used version of Processing is 1.5.1. Can you connect to the Arduino using the Arduino software?

Hi Matt,
I'm in New York and working on building a Pwdr. I have all of the cut acrylic parts and hardware and electronics. I'm having trouble with your software. Whenever I go to connect to the arduino it crashes and gives me this error:
Exception in thread "Animation Thread" java.lang.ArrayIndexOutOfBoundsException: 1

Firmware version 2 is on the Arduino Mega.
I get a similar error when I try to slice any 3D model.
What version of Processing are you using?

I am using Processing 1.5.1. I am able to connect to the Arduino through processing and am now able to connect the Arduino to your software and manually control the axes of the printer. I am getting an error now when I load a model and then try to convert. When I press the convert button I get the error :

file://localhost/C:\Users\Mobi\Documents\Pwdr\teapot.stl
Loading STL...
File Loaded, Slicing:
X: -6.304 - 6.304 Y: -3.931 - 3.931 Z: -2.4 - 3.472

It highlights the line in error as Line 74 in your convertModel class which reads:
print_data[index] = byte(unbinary(LowerStr2));

Any idea whats going on?

No, this is a known bug. Some stl files don't work, but I don't know the
reason.

This is a file that you suggested to use on thingiverse. The Utah Teapot. I contacted you through thingiverse about it and you suggested that specific model as a model that works well. I'll upload a video in the next few days to show you what we are up to. Thanks for your help.

from pwdr-model-0.1.

I found the source of the problem with that. Now I can get it to slice the Utah Teapot. The problem was your array print_data. On Line 28 of convertModel the layer size was only half the size needed to actually slice and get all the data. The line had to be changed to :
byte[] print_data = new byte[layer_size*2];

I'm now working on putting the rest of the electronics together. I see in your two electronics drawings you have one with an SD card reader and one without it.
In the file : Pwdr Protoshield + Stepper Drivers_schem.pdf
you have no SD card and it seems that this is the correct wiring since if I connect the steppers to the indicated pins it will move them.

In the file : Pwdr-Circuit-0.1.pdf
You have an SD card reader, which isn't in your parts list. The firmware also gives out serial commands that say that it can't initialize the SD card. What pins should I be connecting the SD card to?

from pwdr-model-0.1.

I connect SD card using the method in this link http://arduino.cc/forum/index.php/topic,8314.0.html
So, my scheme now looks like this

Thanks Boreaz!

I got my SD shield yesterday and tried out what you suggested. I got the examples working for the SD shield using the pins 50,51,52,53. When I use Pwdr Firmware V2_0 I still get the error "Initialization SD failed". I kind of expected this error because in the firmware those pins are used for the control the X motor.

Is there some other version of the firmware that your using?

from pwdr-model-0.1.

Yes, I made ​​a few changes in the firmware for working with this scheme, try this version https://github.com/Boreaz/MyPrintfiles

You can just adjust the pins of the motors to the correct values for your board.

@Boreaz could you do a pull request?

Thanks for the help Boreaz. I'm up and running now. Now I have to finish putting together all the laser cut parts.

from pwdr-model-0.1.

@atticdweller We are running into the same problem with the line print_data[index] = byte(unbinary(UpperStr2)); do you have any idea? we need to fix this problem as soon as possible. pLEASE HELP!

@ckd28

If I remember correctly I was having all of the problems from using the latest version of processing and Arduino. I remember I needed to use some version of Arduino before 1.0 but can't remember specifically the version. Good luck.

from pwdr-model-0.1.

Please keep in mind to use Arduino IDE version 1.0. I'll investigate what
needs to be changed for the newer versions.
