Hello, you need change how you've stored the files.

The polargraph firmware should be in:
Documents\Arduino\polargraph_server_polarshield\

Accelstepper, UTFT and UTouch libraries must be in:
Documents\Arduino\libraries\

If you haven't got these, then the easiest way to get them is by downloading the code bundle (https://github.com/euphy/polargraphcontroller/releases/latest) and then looking in arduino-source in the zip.

sn

ok...got the Firmware on the board, but it does not connect to your polargraph Controller 🙁 when i plug in the USB there appears a COM4 atthe Serial port selection. but i only receive the message: polargraph is not connected. I tried to Change the properties file from controller.machine.serialport=-1 to 0 and to 4. but no effect.

sorry for such absolutely beginner questions

cheers
thomas

hello sandy,
not really a feeling of success 🙁
here is what the Serial Monitor tells me.

POLARGRAPH ON!

Recalc pageHeight in steps (-2147483648)

READY_200

I do not see a ready every couple of seconds.
the controller.machine.serialport in the properties should be 4?

thanks

thomas

ok, then obviously something is wrong 🙂 the READY_200 does not repeat. the adruiono board works, the Basic LED on/off sketch does work well. I also compiled the firmeware once more but wthout success
cheers

Hey is there any chance you haven't commented out the #define USE_LCD line?

https://github.com/euphy/polargraph/wiki/Using-the-Polargraph-software-with-RAMPS-motorshield#use-lcd

hurray 🙂

I changed the line in polargraph_server_polarsheild.ino

from

// for working out CRCs
static PROGMEM prog_uint32_t crc_table[16] = {
    0x00000000, 0x1db71064, 0x3b6e20c8, 0x26d930ac,
    0x76dc4190, 0x6b6b51f4, 0x4db26158, 0x5005713c,
    0xedb88320, 0xf00f9344, 0xd6d6a3e8, 0xcb61b38c,
    0x9b64c2b0, 0x86d3d2d4, 0xa00ae278, 0xbdbdf21c
};

to

Might work for you as well.

Is there any walkthrough on setting up this for the first time. I have no idea where the linker is looking for files and I cannot even get it to compile. I'm kinda an arduino noob. I am running kali linux and I have the arduino nightly build on the desktop. Which files do i download from github? Where do i put them once I download them? What do i need to do so that all the files are talking to eachother properly and how do I upload it to the ramps board? Basically is there a video tutorial anywhere that covers everything from downloading the project to runnning it?

I added the library files and commented out the stuff I was instructed to but I get a compiler error:

polargraph_server_polarshield.ino:109:16: error: 'prog_uint32_t' does not name a type

Hi there,

I'm just trying to buyild a polargraph with a Mega 2560 board and a RAMPS shield laying from my old 3d printer. But I have a problem to move motor Y (E1 apparantly move normally)
I uncommented the ramp14 line in the polargraph_server_polarshield instead of the Polarshield but it doesn't work
Motor A warms normally while in use but B stay cold.
At the startup the motor grip and is hard to turn by hand but no sound from it. There is sound from the motor A
I tried on a clone Mega 2560 + RAMPS and I tried also on a Chinese MKS Mini board which is based on a 2560 + Ramps also (at least in the PIN assignment)

I tried to tune the Pollolu (On the mega/ramps) and the DRV8825 on the MKS Mini without effect.

I crossed test motors and steppers and they worked all fines.

I tried the X axis instead of Y but it already has been tried here without succes. (Same for me)

If someone could post me his Polarshield sketch, it'll be fine for comparaison.

Thanks in advance,

Asmo
