[HOWTO] Convert Da Vinci Jr to RAMPS 1.4 (Page 9 of 11)

Finally finished and turned out better than expected.  Prints much better than the stock form.  Just have to print a bezel for the LCD (siliconed it in).

The rasberry pi on the right is running octoprint.  Just have to print a mount for it and the camera.  The big wire comes from an atx power supply and brings in both 5 and 12 volts.  The LCD light is powered from it also.

Hello to all I am French excuse I for the translation I modify my printer da Vinci to make a printer with a pen for my children but I am blocked(surrounded) on engines step by step a person would have you he the regulations on grbl speed and or needs he(it) noted the size(greatness) of the plateur and finally at the end of races(shopping) are all they compulsory? Thank you good day

Just wrapping up my modification now. I very nearly completed this in a 24 hour marathon, but tripped myself up at the finish line by leaving my endstop cables connected while I was stripping the wires, and ended up letting the magic smoke out of my RAMPS board (I'm pretty sure it was my RAMPS board, anyway. The Arduino still takes programs and can blink the LED... )

With the number of modifications in Anthem's master branch and my limited understanding of Arduino Sketch, it had too many differences for me to change everything I wanted and have the project still compile, but I have had good success working with the dvjr 1.1.4 branch before the physical switch commit: https://gitlab.com/anthem/Marlin/commit … 0aff61b33a

Items of note:

• I initially couldn't get my thermistor to register correctly. It's thermistor 1, not 4.

• Most items will not work until 12v is applied to the board. Display and 'duino will work on USB power, though.

• The crimpers suggested by Amazon aren't good. I ended up using needle-nosed pliers to manually crimp my connectors after having to throw away a dozen or-so that the crimpers ruined. I have heard great things about the PA 20 and similar crimpers. The heavier/thicker ratcheting crimpers will destroy your terminals, so spring for these or something like them if you need crimpers for the JST terminals and can afford the additional price.

• The DuPont connector set from Amazon comes in two boxes, and the one with the crimp terminals doesn't contain the 1 lead connectors. They aren't two boxes with the same contents duplicated. I didn't realize that until two days into the bulid (facepalm.gif)

Once my new RAMPS board arrives, I will be able to switch all of my cabling over and let you know how it turned out.

Its new name is Scooty-Puff, Sr., because Scooty Puff Jr. Suuuuuuuucks.

I have heard the new firmware 2.2.7 doesn’t allow reset NFC chips to be used. When you talk about resetting the board to possibly make a repeater, would that same reset allow users to wipe the software version to reinstall an earlier version?

This is all true but, 2.2.7 does still allow you to use paper tags if you do not want to mod the firmware.

It's the same except you will loose the WiFi if it has it. Once you take the original mainboard out it is nothing but standard printer parts and it is up to you to pinout the motor and endstops in order to connect them to the controller you chose.

For starters there is no pre-configured firmware for your machine or board. You just have to take it a step at a time. If you are getting errors during compiling then you have settings set that don't fit your board choice in the beginning of the firmware. Selecting a mega2560 or whatever will preset most of the needed settings for that board. The next issue is if you have an LCD with your ramps then you need to use an older version of Arduino such as version 1.5.x. Newer versions don not know how to use the LCD as it is old tech compared to what newer Arduino does.

You will also need the u8glib library added to your Arduino software so the drivers for the LCD can be compiled into the sketch.

I’m guessing there isn’t a place I can send it and have it programmed either? I’ve downloaded and tried every Arduino ide available and get the same set of errors on everyone. The adding the u8glib online adds more errors regarding terms that are not found anywhere in the codes.

I’ve tried every option under mega 2560 and get the same results.

I’ve used all of them. I can get marlin X2 to compline online, but as soon as I add u8g, it goes back to 100’s of errors that contain no lines for the actual code.

Well since you are setting up RAMPS then all you need to do is select the RAMPS board in the firmware before compiling. The only file you should be doing anything in is configuration.h. No other files need to be touched. Personally I used Marlin when I converted my Da Vinci 1.0 to RAMPS.

Maybe this can help some.
