Re: Firmware 3.2.1 for Original Prusa i3 MK2.5

Downloaded the 3.2.1 version from the webpage filename still says 3.2.0 but 576 ?

Hi Gert,
it was just a typo in the name of the file, it is the latest FW 3.2.1, already fixed 😉

Guessed that, fast work thanks.

Re: Firmware 3.2.1 for Original Prusa i3 MK2.5

I'm a little lost and looking for some help.
I have just installed the 2.5 upgrade to my MK2s. I use the PT100 thermistors on the extruder and the bed. I am looking to modify the firmware accordingly. Following the link to GitHub I see the version Firmware 3.2.1 I am unable to use the Hex file as it is not configured for the PT100 thermistors.
When I open the source code that is a Zip file I am presented with the Arduino file but it does not look like the Arduino file for the MK2s that I am familiar with. I assume this is only for the MK3. Does anyone know where I can find the appropriate complete Arduino file For the MK2.5 so that I may make the changes for my thermistors. I have found various other versions on GitHub but they all fail to run the printer properly when the firmware is flashed to the printer. I suppose only version 3.2.1 will work properly as all the other previous versions I have tried had to many errors for them to work properly. If anyone has a link to the correct firmware that would be appreciated, or a ready made hex file, if someone has already done their printer up with the 2.5 with the pt100 thermistors.

Cheers,
Leif Scott

Leif, have a look here.

You need to copy and rename one file as i understand.

Re: Firmware 3.2.1 for Original Prusa i3 MK2.5

If I understand the location correct I follow the link and then select the branch MK2.5 with the new XYZ calibration. This has not worked for me.
What is the file that you say needs to be renamed and what is the new name supposed to be.

Thanks for your help.

Im not a specialist in this.

But, read below chapter at the link i posted: https://github.com/prusa3d/Prusa-Firmware
2. Source code compilation

place the source codes corresponding to your printer model obtained from the repository into the selected directory on your disk
https://github.com/prusa3d/Prusa-Firmware/
in the subdirectory "Firmware/variants/" select the configuration file (.h) corresponding to your printer model, make copy named "Configuration_prusa.h" (or make simple renaming) and copy them into "Firmware/" directory

im trying the octoprint plugin for the firmware update. what settings do i select, anyone that has got this to work with your MK3, any help is appreciated.

Re: Firmware 3.2.1 for Original Prusa i3 MK2.5

I updated my MK2.5 a few days ago using the Octoprint Firmware Updater.

Firstly, you should get the Plugin from the Octoprint Plugin Manager. Then login to the Raspberry Pi via ssh and install avrdude:

sudo apt-get update
sudo apt-get install avrdude

(this is from https://github.com/OctoPrint/OctoPrint-FirmwareUpdater ).

Go to Octoprint Settings -> Firmware Updater and click on the Spanner icon. Then use these settings:

Flash method : avrdude (Atmel AVR Family)
AVR MCU : ATmega2560
Path to avrdude : /usr/bin/avrdude
AVR Programmer Type : wiring

Click Test button to check that the path is correct. Click Save.

Click on the Browse button, select the hex file and click Flash from File.

Re: Firmware 3.2.1 for Original Prusa i3 MK2.5

OK, I have copied the file over and made the name change and all looks like it should, however it won't compile the firmware for MK2.5. I get a error "unrecognizable insn exit status 1" I have tried many different versions, 3.1.3, 3.1.4, 3.2.1 I am running Arduino 1.6.8 and have installed the Rambo board in the preferences from https://raw.githubusercontent.com/ultim ... index.json
I have tried uninstalling everything and reinstalling, with no change.

I have been able to compile the MK2.5 with the new xyz calibration. After successfully uploading this it will run the Z calibration but will not run the first layer calibration. When a print is tried it runs the Z calibration and then stops. there is a message on the screen showing "STOPPED" it will not respond to commands sent through the USB even though it is connected.

I have loaded a slightly older variant for the MK2s and it compiles just fine.

Any thoughts would be appreciated.
