Alligator Board Q & A

Hello Mark O,

yes i did all the things discribbled in the 3dArtists Github. And I also took the Github Version of the Repetier Firmware and i tried the Repetier 0.92 with the Configurator. everytime the same. Strange is , that the Board is not coming up with the MCU USB Port, how should i program it , when Windows is not taking the Board ?

Greetings

If your computer does not see the board it is not possible to program it, so something is wrong.
Is the dipswitch near de mcu toward the processor? (dont know if this affects the usb serial connection)
The way it works for me was connecting 12v power, usb on the usb/uart port (nr8 in the layout pictures, virtual com port) and it showed up on my pc. I havent tried the other usb port because it worked with nr8.
If you connect 12v and the usb in nr 8, does it pop up on windows?

Hi,

the Dipswitch is toward the Processor.
When i Power 12V and use the USB UART Nr8, Windows will see the Board.
When i use the Native USB without 12V nothing happens , Windows dont see the Board.
Dipswitch is toward Processor.

Tomorrow i try a different Computer with USB 2.0 maybe thats the issue... In the past i used some Arduino Clone with different Driver , so i take a look on a fresh and clean Windows .

I tried the same thing now, and when i connect the board via the native usb to my computer (without 12v), nothing happens. Also the uart does not work without 12v.

When connected by uart i can upload firmware and make a connection from repetier so you dont really need the native usb? I think you need to upload firmware via the uart (nr8) usb port with 12v connected, so you can check if everything works.
Where can we find the usb settings for the native usb port?

Also in the user manual:

Quote

There are two USB interfaces
The native microcontroller USB port (able to be used as USB OTG port)
The USB/UART port
WARNING: Native port has OTG function, they
are directly connected to 5V power!
Do not connect Native USB port to the PC in presence of 12-24V power input.
Communicate with Alligator and with your printer only from the USB/UART port.
Native port should be used only as Host OTG.
Native port connected directly to the PC can be used only for board testing without 12-24V power input (for expert users only!)

It says that communications with alligator only by the USB/UART port is possible, so you should try uploading the firmware by this port with 12v connected and by following the steps on [github.com] to erase the flash and upload firmware. At least this worked for me on first try.

Mark O, your description is exactly the process, you folks are going through as I did, many, many, many times as I built mine (and sometimes still do in cases like these)

make sure that you have gone out to github and pulled in the alligator board arduino variant drivers for the arduino IDE. without that, it might make all this irrelevant...

[github.com]

if all is well and you have all that, then this should be how it works to compile and upload:

1. power to the alligator board
2. USB to the UART USB port on alligator board (windows should find it as an HS232; this is normal. Windows 7 might need a driver for this -I don't know. I am using both Windows 8 and windows 10+, and HS232 seem to be part of the OS (imagine that)
3. in the Arduino IDE, make sure you have the correct bootloader selected: I use Arduino ISP
4. under Board settings, make sure you have selected alligator Board R2 3D printer controller (USB/UART)
5. have a drink.
6. under the COM ports, make sure you have your COM port selected. if you cannot find the right COM port, it may be found under Device Manager|ports (COM & LPT).

on the MCU port,
the issue here is that the port is based on USB OTG, which means that it is a supplement to USB 2.0. in other words, you will need a USB 2.0 capable port to be able to use the MCU. all that being said your USB port will need to be able to provide enough power to the board to be able to program it, but it may not be enough to actually *drive* the board. what I did, for example, if plug in a powered USB hub, and plugged in my board to that, and the hub to my USB 2.0 port on my laptop. while it did work, and I was able to program and prove programming via MCU is *much* easier (i.e. no need to dip switch, methinks), the ideal and recommended approach is still the UART port, makes it much more simpler to remember, and less back and forth between ports- which *can* become brittle if you play with them too much -fair warning - just back and forth on a dip switch

hope this helps.

Hello,

This is helping me a lot ! And now ive the Problem. Arduino IDE normaly uses the AVRMK II Programmer and with this i tried to progam this. I try using the Ardiuno ISP Programmer now. OK, your Boards seem to act like my Board , so on, so fine :-)
Next i try your Ideas and will Report...

At the 3D Artists Github Page you have 2 Sites for the Alligator Drivers , witch one do you use ? There is Github-Alligator Page and Github-Alligator-Repetier-Firmware Page ... witch one is the right one ?

I hope i didnt break anything on the Board by trying wrong things ...

Greetings and Thanks a lot

I now see there are two places where r2 drivers are, i used the drivers in the Arduino Variant folder (the 1.6.3 version [github.com]), but i dont know if these drivers and the drivers in the repetier folder are the same?

I tried the same thing now, and when i connect the board via the native usb to my computer (without 12v), nothing happens. Also the uart does not work without 12v.

From Alligator serialnumber greater than 76, the board is not powered via USB, we added this change for use native port with 12V power in.
You can find the serialnumber of your Alligator on the bottom of the board.

For the Repetier-Firmware is recommended to use the files "alligator_r2" inside Repetier repository.
Variant files inside Repetier repository maintained by repetier and necessary for this firmware.

For other firmware as MarlinKimbra-Firmware use the 3dartists variant repository.

Thanks Marco, i will change the firmware to the version in the repetier folder.
Still waiting for the last parts to come to start building!

Marco, does that mean, then, that rev 2, post ser. #76 boards will be able to directly use the MCU for programming *and* control? with 12/24v power?

I just might order another one...

Hello,

this is , what i did :

- uninstalled Arduino 1.6.3
- deleted Folder Arduino15 C:\Users\PELLE\AppData\Roaming\Arduino15

Hello I got mine a few days ago, all manage to run but can not get it to run stepper motors, making them move they freezes, what wrong? (What is proper connecting cable colors red/green/yellow/blue?) nema17 they are 0.6A
I use repetier firmware:

#define MICROSTEP_MODES { 32,32,32,32,32 } // [1,2,4,8,16,32]
#define MOTOR_CURRENT_PERCENT { 24,24,24,24,24}

shteecers
to test your motors, (without any power) cross the red and green, and then try to manually move the rod back and forth. if you have any resistance, they might be your pair. then attempt to do the same with red and yellow, red and blue. feel which ones give you resistance. once you've gotten a pair, it's just a matter of figuring out the pulsations. mine for example, are red/blue, and green/black.

once you have that figured out, plug them into the board, make sure you have them all nice and snug inside the plugs. depending on the # steps will also affect your steps/revolution, so that will also need to be accounted for.

I've not seen MOTOR_CURRENT_PERCENT, I've seen it as MOTOR_CURRENT is this something new or recently changed in the main?
I've used the repetier for alligator firmware offered here: [github.com]

if you have .6a motors, MOTOR_CURRENT would be set to 62, to reflect 24% of the driver's amperage range, or .6a

(MOTOR_CURRENT/ 255) * 2.5 = y amps out

@JET-A1,

these steps are not necessary:

Quote
- install Glib8U
- copy 3DArtists/Github/Repetier/Boards/Arduino1+ Hardwareserial.h to C:\Users\PELLE\AppData\Roaming\Arduino15\packages\arduino\hardware\sam\1.6.3\cores\arduino

Arduino1+ Hardwareserial.h file should not be copied, this is creating your error.
Glib8U library is integrated in Repetier .

@ shteecers

Latest version of Repetier use MOTOR_CURRENT_PERCENT , previous versions use MOTOR_CURRENT.

MOTOR_CURRENT_PERCENT is the percentage of current, 0-100% , 100% is 2.5A.
MOTOR_CURRENT is raw value , 0-255 , 255 is 2.5A.

What is the model of your motor?

@ EljefedsecurIT

you can use the native port (with 12V) by simply removing the red wire from a standard USB cable.

Hello,

good News, I got the Repetier Firmware on the Alligator ... YES ... After many try and error I put the Arduiono 1.6.3 ZIP File ( no Admin install ) on my D: Drive and it works with both UART USB and MCU USB .
I don't know whats the difference between the Arduino.exe and the Arduino.zip ?!?!
Important is the following, USB MCU PORT gets his Driver from Arduino\Drivers\ and the UART USB PORT from Arduino\Drivers\FTDI\ .
At WWW.ARDUINO.CC under Learning, Getting Started, you can read, how to set up the Drivers right, for Arduino DUE.

I also got the actual Repetier Firmware 0.92.3 flashed to the Alligator . The additional Files arduino_due_repetier and Board.txt are incuded when you download the entire Firmware from the Repetier Configurator Page.

I am glad it works now.

Greetings

I made a Map, you can see witch Pins should welded together:

Alligator Pin 1 (+5,0 Volt) to Display EXP1 Pin 10
-------------------------------------------------------------------
Alligator Pin 2 (3,3Volt) NO CONNECTION
-------------------------------------------------------------------
Alligator Pin 3 (LCD-RS) to Display EXP1 Pin 4
-------------------------------------------------------------------
Alligator Pin 4 (Buzzer) to Display EXP1 Pin 1
-------------------------------------------------------------------
Alligator Pin 5 (LCD-D4) to Display EXP1 Pin 5
-------------------------------------------------------------------
Alligator Pin 6 (ENC-EN2) to Display EXP2 Pin 5
-------------------------------------------------------------------
Alligator Pin 7 (ENC-EN1) to Display EXP2 Pin 3
-------------------------------------------------------------------
Alligator Pin 8 (ENC-BTN) to Display EXP1 Pin 2
-------------------------------------------------------------------
Alligator Pin 9 (LCD-E) to Display EXP1 Pin 3
-------------------------------------------------------------------

Hello I just purchased my alligator board at the beginning of this week. What has been your guys experience with shipping times to the states?

Hi,

I have for sale a NIB Alligator board 110€, shipped with tracking, worldwide.
Shipment only to confirmed Paypal address, no exceptions.

Solved: used the github Alligator-Arduino-variant instead of the ones listed for repetier and everything worked out fine.


I keep getting this same error. Any ideas where I am messing up?

Ok this is really the first time I have attempted really changing the electronics around and messing with the firmware. So far it has been extremely frustrating at times but I kept with it and after hours of reading I'm proud to say I think I'm starting to get it. I have it up and running on my reprappro mendel using repetier. I even build my own z probe and somehow get it all working.

Now here is my problem. I'm trying to hook up a mini servo to make my z probe completely automatic but I have to clue which pins are which. Using the repetier .92 config tool it list the usual pins such as fans and heaters. But then it says digital pins 1-50ish. I have tried all three PWM connection using the default digital pin 11 in the firmware and nothing. How is it I figure out which pins is what? Also am I correct in thinking that the PWM pin is capable of controlling the signal wire of the servo?

Hi Brex480,

you can connect a servo to the PWM connector (black connector near to USB ), this is a pinout :

PC4 D36
PC8 D40
PC9 D41

in Repetier sets :

#define FEATURE_SERVO 1
#define SERVO0_PIN 36
#define SERVO1_PIN 40
#define SERVO2_PIN 41
#define SERVO3_PIN -1

Prusa Mendel + Alligator Board with MarlinKimbra Firmware

Hey Marco? I don't think I ever got clarified; will the alligator board support microstep modes 1,2,4 and 8? I've honestly only seen references for 16 & 32,and all my stuff runs on 32 for my delta...but this 2nd printer might need a geared stepper.
I am looking at a geared motor for a z-axis design and would rather not microstep, and I would like to think lower microsteps are in the repetier and marlin firmwares?

just checking before I go hacking around in the code...

Hi EljefedsecurIT ,

via firmware can be configured only 1/16 or 1/32 micro-stepping, for 1, 1/2, 1/4 ,1/8 is necessary to solder a jumper on the board.
MS0 e MS1 are controlled via firmware, MS3 (necessary for 1, 1/2 , 1/4 , 1/8) is chosen by the user and require to well a resistor jumper in position R59 or R128 (0 ohm ) see Alligator schematics (page 15).

Hello me again. Thanks for the help with the servo. I hope to test it out this weekend. Also ordered piggy lite and a e3d cyclops so should be having some more fun in the future.

Anyways the point of this post is I'm wondering if the board supports atx power supply standby? If so has anyone ever tried controlling a normal power supply with a 120v relay and a second small 5v DC adaptor for standby V? Only thing I'm not sure of is what kind a current the control coil for that large of relay would require but I'm sure that can be overcome pretty easy with a second relay or something. Any help in this little idea I have would be great as I hate starting a few hour print then having it just on while I'm stuck at work.

I am enjoying my Alligator, but I am having a slight problem. Has anyone been able to get PWM control working with MarlinKimbra? I can only get my laser to turn on or off, but no TTL. Pin 36 reads 0.5v when off, and 3.3v while on. If I send M3 S(0-127) the pin stays low, if I send M3 S(128-255) the pin goes high. I have scoured the code but I cannot seem to find the problem. I assigned the pins in LASERBEAM function and made sure it is defined in the config file. I have tried using M42 command to control the pin directly as well with the same results. Any help is much appreciated!

Hi daa5933,

is a software error in MarlinKimbra, Mago Kimbra has solved the problem, try again with the latest code on github
