This firmware repository is not current and is maintained for legacy purposes. There are two slightly different configurations: 1.
The leading developers of Sprinter are currently Kliment and caru, though many others contribute with their patches. It supports printing from SD card, active heatbed control, and ATmega internal pullups. It is based on Tonokips's firmware, which was licensed under GPL v2 or later. So before attempting any print, you will have to check all your axis max speed, including the extruder retract speed.
Not following this guidelines can seriously damage your printer. The configuration file now has an option to set the wanted temperature table file. If you copy and paste a temperature file from older versions, make sure that the configuration is pointing to it. For example: include "ThermistorTable.
To do so, comment out the following lines in configuration.Posted by kkwong I have installed arduno 1. How do I write configuration. Reply Quote.
Anyway, as a rule of thumb, always double check what people write. Is that the correct step! The y and z axis the same. I can't change the switch setting. How do I add setting to configuration. Hey KK, where was your config. I have looked everywhere to no avail. First, use a continuity tester to find the 2 pairs of the motors. Connect them to the board, one pair on first two connectors and the other on the two lower connectors.
Check which direction the motor moves. Is that the correct configuration. I try to open other configuration.
I tested the stepper motors all can turn clockwise and anticlockwise. Attachments: open download - tool. If yours says true make it false or if yours says false change it to true Compile and upload the new firmware Reply Quote.
What can I do?A compact all-in-one controller board for RepRaps with one extruder head, optimized for mass production. The point of RepRap is to make itself, of course. But sometimes people just want plug-and-play RepRap electronics so they can concentrate on the other aspects of the machine, or just because they are more software or mechanics oriented than electronics oriented. Melzi is designed to be a complete set of RepRap electronics that should be very cheap to mass produce.
It was originally based on the Arduino Leonardo and is named after Francesco Melziwho was Leonardo da Vinci's pupil. However, problems with the routing of the fine tracks on the PCB quickly became apparent, which made them hard to make reliably. Often thermistor readings are inaccurate, or fail.
Some cheap online sellers still sell this version of the Melzi! See 'How to get it' list lower down this page. Most listings online for "Melzi 2. Firmware for the 2. Some boards register a full 10C less than they should As a general rule these boards should not be trusted. Version 1. Version 2.
Most boards are supplied with bootloader and firmware pre-installed and the stepper driver currents preset. If not, read on These also allow you to flash the bootloader using an appropriate programmer. There are more detailed firmware instructions on the RepRapPro site here. As an alternative to the Marlin firmware there's the Repetier firmware for the Melzi which in my case worked better than the Marlin firmware.
More details about this firmware can be found here. There's also a special firmware configuration tool v0. If you like Repetier you can donate some money. Before the module can be used the baud rate must be changed from default to The module shouldn't be paired at that moment. Use a terminal program and issue the following AT commands:. More details about the configuration you will find here [  ].
We must level-shift the logic from 5V to 3. The Melzi has an D IC with unused buffers that we can use.TRONXY X3 Проблема с подключение к ПК [MELZI 2.0_v5]
A total of 5 wires must be soldered. Note that the TXD outputs are connected in parallel which is not recommended. On Arduino boards the serial chip is connected to the main IC via 1kOhm resistors for this reason.Melzi V2. Its plug-and-play capability contributes to less time consuming for development and installation. Melzi 2. Power supply of logic part: connect 1 and 2 for external power supply; connect 2 and 3 for power supply from USB.
Windows users need install driver before uploading. As shown below. Upon uploading, IDE will display the rate of progress; when done uploading appears, the uploading process succeeded. After uploading, you can go on to the next step.
If you cannot upload, check the dialog box below to identify the problem and solve it. The common mistakes are the wrong select of type of board or serial port etc. The parameters that need setting are as below, for those not mentioned just leave them as default. This parameter is for the baud rate of serial port. Note: a successful communication can be realized only when the Baud rate of upper computer is identical with that of Firmware.
The Baud rate is not set in random.
The last three are frequently used for 3D Printer. This parameter is set for board type. The parameter of Melzi V2. For other board, you can refer to the annotation on the board. The two parameters are set for the type of temperature sensor respectively. They are the critical parameter to check if the sensor read temperature correctly.
You must modify depending on the temperature sensor you use. This parameter is set to avoid potential risks when the extruder operates before reaching the rated temperature. The three parameters are set for the end stops of three axes. If the configuration is true, the end stop outputs 1 in default condition, and outputs 0 when triggered. That is to say, mechanical end stop should connect to the NO normally open contactor.A compact all-in-one controller board for RepRaps with one extruder head, optimized for mass production.
The point of RepRap is to make itself, of course. But sometimes people just want plug-and-play RepRap electronics so they can concentrate on the other aspects of the machine, or just because they are more software or mechanics oriented than electronics oriented.
Melzi is designed to be a complete set of RepRap electronics that should be very cheap to mass produce. This is a Sanguinololu firmware compatible board, though does have a couple of extra features the Sanguinololu does not - namely the extra Mosfet for the fan, and a software controllable LED. Melzi has micro SD on board as well. A full StepStick clone is on board as well negating the need for external stepper motor drivers.
One such is Generation 7 Electronics . Bootloader and firmware are entirely independent from each other. There are several ways to accomplish this. A great tutorial on how to do this is listed in alphabetic order below. We will try and complete tutorials on the other methods as we have the time.
Symptoms of incorrect fuse settings: X axis only moves in one direction.

Endstops do not work. Example using avrdude and usbtiny. Firmware You will need to upload a RepRap firmware to your Sanguinololu once the Bootloader has been burnt. If you know of other working firmwares than what is listed below please feel free to add them. File:Melzi Schematic. File:Melzi printer. The Melzi [insert cool name here] is a Melzi board based on the new and upcoming Arduino Leonardo. Click here to buy Melzi.

I had a spare Arduino laying around and found out I could use it to flash the Melzi board which is normally done with a standalone AVR programmer. Did you use this instructable in your classroom? Add a Teacher Note to share how you incorporated it into your lesson. Disconnect the printer power supply from the back.
Remove the back of the box and slide the bottom of the box toward the back, and place the two pieces somewhere convenient close by. You can unscrew the four hex socket cap screws that keep the Melzi board in the box to have more freedom.
You can probably skip this part but I find it easier to manage with it outside the box. Arduino gives you a little more info about this process here. Whatever device you are using, this is called the ISP programmer. Install Arduino 1. Now we need to burn the bootloader to the Melzi.
However you do this, connect the pins on the Arduino to the Melzi board ISP pins on the bottom of the board. As per the schematic, ensure the following pin connections:. This should take about one minute or so and will notify you if successful. Remove the headers from the the SPI pins on the Melzi board. I have used a nice version of the repetier software modified by Max Bian on the Wanhao google group:. Download the firmware and extract it somewhere and open the.
You can use whatever firmware you like.
Flashing a Bootloader to the CR-10
I will be referring to this one though. This ensures the thermistor of the e3d can be used correctly if you want to use the the e3d v6 hotend — In the configuration. This ensures the rotary encoder on the box is nice and smooth - In the configuration.The Melzi board contained in the Creality CR does not come pre-flashed with a bootloader. A bootloader is what enables us to write firmware over usb.
If we plan on flashing new firmware and don't want to have to take the control box apart every time, we need to flash one. I had an Arduino Uno lying around so that's what we'll use for this demonstration. Note that the firmware I provided is almost totally stock. I made no real modifications.
Using an Arduino to Flash the Melzi Board (Wanhao I3) and Upgrade Firmware
I simply provided this for others who wish to modify their firmware. Did you use this instructable in your classroom?
Add a Teacher Note to share how you incorporated it into your lesson. Once connected we will have to determine which COM port your Arudino is using. Once you've moved the power supply out of the way be careful as some of the wires connected to it are not very long you should be able to see the controller board. You can either remove the controller board from the housing or leave it in place. I chose to leave it in place to save time. If you do the same, find something to prop up the power supply.
You can find it's location on the picture I attached. Now we have to wire our Arduino to the Melzi controller board inside our CR I've attached a few pictures to see how this is done.
I recommend using female to female jumper wire to do this but any way you can wire this can work. It should be wired as follows:. If you line up the Arduino and Melzi like I have in my picture, you can just connect the pins on each board as you see them top left to top left, bottom left to bottom left etc.
You can make this connection with a female to male jumper wire or you can do what I did and just slide a small pice of tinned wire in one side of a female to female jumper wire. At the bottom of the Arduino IDE window, there will be a small black box that should say it completed successfully. So you're sure you did everything right and you tried to burn bootloader yet it didn't work? Here is an Alternative Method using a sketch made by a brilliant man named Nick Gammon.
Now that our Melzi has a bootloader burned to it, we can flash it via USB. You can disconnect the Arduino from the Melzi board now. For the firmware I provided on the Facebook group, you will need to download Arduino v1.
You can find it on Arduino's website. You will also need to extract the Sanguino folder to the hardware folder of the Arduino v1.
