First of all my printer description: 1) Reprap Melzi 2.0: Processor: ATMEGA1284P (Sanguino compatible) 2) Repetier Host with Slic3r 3) Firmware EEPROM I have been using my printer to print out stuff, using baud rate setting of 115200, THE PROBLEM STARTED when I tried different BAUD RATE setting in FIRMWARE EEPROM configuration to 230400....whenever I tried to connect the printer: - it connects only for 2-3 seconds then disconnected by itself - I have changed the baud rate in both my FT232 USB to 230400 and repetier printer setting to 230400 as well....the previous problem still happened Then I decided to use ARDUINO, have succesfully connected my printer with the software, downloaded all the necessary configuration change from the repetier website (cant post URL here) but when I tried to upload the file: "Third-party platform.txt does not define compiler.path. Please report this to the third-party hardware maintainer. Error while uploading: missing 'recipe.cpp.o.pattern' configuration parameter" Can anyone please help me solve this? ive been struggling with this thing for a looooong time Regards https://reprap.org/forum/read.php?262,485584,485584#msg-485584 Fri, 17 Apr 2026 11:38:20 -0400 Phorum 5.2.23 https://reprap.org/forum/read.php?262,485584,488310#msg-488310 https://reprap.org/forum/read.php?262,485584,488310#msg-488310

Also, keep in mind -- the Arduino board can only hold one program at a time -- if you upload the EEPROM eraser -- then you'll have to let it run until the light blinks on -- and then you'll have to recompile your firmware and reupload it as well.

Also, why are you running such an old version of the Arduino software? Update to 1.6. -- You should be able to compile Repetier firmware without issues from a fresh install of the latest Arduino environment.]]> BrainSlugs83 Printing Tue, 24 Mar 2015 16:12:18 -0400 https://reprap.org/forum/read.php?262,485584,487859#msg-487859 https://reprap.org/forum/read.php?262,485584,487859#msg-487859

the firmware was there in the board when I first purchased the parts (when I install repetierhost, I could access the firmware EEPROM settings)]]> romeo2die Printing Sun, 22 Mar 2015 19:18:07 -0400 https://reprap.org/forum/read.php?262,485584,487088#msg-487088 https://reprap.org/forum/read.php?262,485584,487088#msg-487088
How did you get the firmware on the board in the first place? -- Was it using the Arduino software or some other method?

If you have a way to reinstall the firmware on the device, I recommend clearing the eeprom -- you can do this from the command line with AVRDUDE (etc.) if you're familiar with the toolchain, or you can upload a new program to the Arduino that when executed (i.e. when you reset the board) it will clear the EEPROM. But then after you do that, you need to reupload the original Marlin firmware back onto the board.

Here's an example: http://arduino.cc/en/Tutorial/EEPROMClear]]> BrainSlugs83 Printing Sun, 22 Mar 2015 19:11:57 -0400 https://reprap.org/forum/read.php?262,485584,486908#msg-486908 https://reprap.org/forum/read.php?262,485584,486908#msg-486908
PREVIOUS CONDITION:
(I was using baudrate of 115200) - EEPROM, Printer setting, device manager setting, and it was working perfectly fine.)

When I changed the baudrate in EEPROM, I started to get this problem.

CURRENT CONDITION:
1) EEPROM setting still in 230400 ( I cannot change it back, cos the option in repetier host cannot be selected, whether or not I connect the printer
2) I have tried to change both printer manager and device manager baudrate to match current EEPROM baudrate value to 230400, but still not working


Btw, thanks for the previous reply, greatly appreciated]]> romeo2die Printing Sun, 22 Mar 2015 10:57:59 -0400 https://reprap.org/forum/read.php?262,485584,486855#msg-486855 https://reprap.org/forum/read.php?262,485584,486855#msg-486855
So, you don't set it in 'EEPROM Settings' in Repetier, but in the 'Printer Settings'.

If the baudrates both match, firmware and software, you can connect and it works.]]> Ohmarinus Printing Sun, 22 Mar 2015 08:05:16 -0400 https://reprap.org/forum/read.php?262,485584,486739#msg-486739 https://reprap.org/forum/read.php?262,485584,486739#msg-486739
the BAUDRATE will affect only the controller board? am i right?]]> romeo2die Printing Sat, 21 Mar 2015 23:29:31 -0400 https://reprap.org/forum/read.php?262,485584,486736#msg-486736 https://reprap.org/forum/read.php?262,485584,486736#msg-486736 romeo2die Printing Sat, 21 Mar 2015 23:26:58 -0400 https://reprap.org/forum/read.php?262,485584,485645#msg-485645 https://reprap.org/forum/read.php?262,485584,485645#msg-485645 jbernardis Printing Thu, 19 Mar 2015 12:43:01 -0400 https://reprap.org/forum/read.php?262,485584,485641#msg-485641 https://reprap.org/forum/read.php?262,485584,485641#msg-485641
I assume you must be using Repetier firmware as I am not aware that Marlin stores baud rate in EEPROM. Perhaps there is a method to perform a factory reset on the firmware to load defaults.

after I changed the baudrate via FIRMWARE EEPROM configuration (repetier-host), I cannot open the configuration window anymore (ALT+E).
the option in config - FIRMWARE EEPROM config is always greyed out....I cannot click it anymore]]> romeo2die Printing Thu, 19 Mar 2015 12:25:20 -0400 https://reprap.org/forum/read.php?262,485584,485612#msg-485612 https://reprap.org/forum/read.php?262,485584,485612#msg-485612
You need to set the same baud rate in the firmware and host configuration.

The standard baud rates are subject to significant error on a 16MHz processor as used on the Melzi. You will have more luck running at 250,000 baud.

I run my Melzi-based Mendel90 at this baud rate all the time.
