[HOWTO] Convert Da Vinci Jr to RAMPS 1.4 (Page 10 of 11)

Why are you swapping the Configuration.h file. The default file as it is with the default version or repetier firmware you download from github should be close to running your machine. All you need to do is set motor directions, endstop settings, and select the proper board and display and then compile it.

I have never had to swap any file on any conversion and I have done several.

I misunderstood about the library and got it added (to the software not the sketch) it compiles now, but my board is no longer recognized for uploading.

I figured it out. I had to uninstall ALL arduino software on the computer. Then on the online version I could upload blink. Log out, reinstall the IDE and then it is recognized. I think it happens because I use Mac and not PC.

Now, I am trying to make the needed changes to only use 1 extruder/hotend and 1 bed heater. I changed the values in

configuration.h to: #define EXTRUDERS 1 (1 was originally 4)

and numbers in () are the original coded numbers.

#define TEMP_SENSOR_0 5 (5)
#define TEMP_SENSOR_1 0 (5)

// Same pin as TEMP_SENSOR_0
#define TEMP_SENSOR_2 0 (5)
// Same pin as TEMP_SENSOR_1
#define TEMP_SENSOR_3 0 (5)

#define TEMP_SENSOR_BED 0

As expected I get multiple errors:

Error compiling.

Any ideas which single character I need to adjust? I do appreciate all the help, I can build anything electronic, but programming is defiantly my weak spot.

  This report would have more information with
  "Show verbose output during compilation"
  enabled in File > Preferences.

That one gives me 100's of missing binary before token '(' errors.

Thanks, a few minor adjustments (turning on the bed heater) and 1.1.7.1 seems to be working. Unfortunately, weather has delayed shipments so I won’t know for sure until Tuesday :-/. Just to make sure, are the settings for the da Vinci extruder and hot end?

Thank you. My end goal is the E3D Titan Aero, but I haven't ordered it yet. The other parts should be in Monday and Tuesday. With any luck, I will have a working printer by the end of the week :-). I learned the hard way to save the original file under a different name so I can go back, didn't realize compiling it saves the file and there is no "undo" button.

I am down to one issue

Z axis only moves down regardless of which way I tell it to move (tell it move up and it moves down the number of steps told to move up). It operates properly when plugged into the X or Y pins.

edit: the issue was the ramps 1.4 board was bad. After replacing it, everything moves properly, hot end heats up, bed heats up properly, extruder runs (as long as the hot end is hot).

When trying to print the extruder homes properly, then goes all the way past the build plate to the top right corner and then drops the z axis below the plate and gets caught on it. I tested the x axis, homed it, then told it to move 10 mm, it moved almost 18 mm. I have dropped the steeper values to 1/4 of what they were and also tried 4 times higher than they were and seem to get the exact same positioning (over reaching the build plate). I can copy the configuration.h file if that helps? Would I be better off mounting axis max sensors or am i just showing my lack of programming skills?

Is the same number of jumpers installed in the same locations under the x and y stepper driver as the z? Turn power off before removing stepper drivers to check.

Also it is never said anywhere but on the initial flash you need to have EEPROM chitchat turned off until you get everything set up the way you want. What happens is when Chit chat is turned on the initial firmware settings are written to the EEPROM and stored. Each time the machine is booted the settings are recalled from the EEPROM. Those settings get priority firmware settings. If you leave Chit Chat off then on your firmware settings will be used.

EEPROM Chitchat is a setting in the firmware towards the bottom pf the configuration.h tab in Arduino.

Just comment out those three lines and check your settings. The next time you power up it should pull the firmware settings and not the EEPROM settings.

You can just leave it. Not real sure what advantage to having it stored in the firmware is except maybe a failsafe back up. If you where to re-enable it then it should store the new correct settings.
