Topic: Converting to ramps 1.4

I am removing the stock davinci board to install a RAMPS 1.4. I am curios if there is any firmware out there or guilds to doing so. The specific board I am buying of amazon is listed bellow. Also does anyone know if you can use the existing end stops instead of installing new end stops? The videos I have found on youtube on the subject are poor quality and of little value.

Re: Converting to ramps 1.4

I have heard a lot of mixed things on the end stops..  I would be curious as to what you find..
Also if your interested in selling your old board if it works let me know. I have one of my printers with a board thats dead.
Enjoy your weekend.

Re: Converting to ramps 1.4

Unless you have endstops that have onboard current limiting resistors which I doubt since there has been no news on a board design change, you cannot use the existing endstops unless you add current limiting resistors inline with the wires. The stock board has them built in so there are none on the stock opto sensors. After market sensors have the so the RAMP was never made with them on board.

So simple answer is with out adding current limiting resistors you cannot use the stock opto sensors.
