Topic: Ramps 1.4 Detailed Build information

I'm saving this post for next week. I will be installing ramps 1.4 on the davinci 1.0. To be continued....

I hope with my graphics background I can create something very detailed that anyone can follow with little background of electronics and software.

The parts I am using are:

Ramps 1.4 with MEGA 2650
Ramps compatible lcd and SD card slot
Ramps compatable optic endstops
LED Strip 12v (http://www.amazon.com/gp/product/B00N3W … ailpages00)
Jumper wire cables female pin connector 2.54mm - for wire crimping
Jumper wire cases for pin connectors 2.54mm - for wire crimping
Crimper tool that can crimp 2.54mm
Wire splicer/cutter to clip and expose wiring in wires
Kapton Tape
Hot glue/gun
Solder Wire
Solder tool



Important Notes

Because ramps 1.4 only supports 12v anything on davinci that runs on 9v 5v or 3v will need to be replaced or modded. I'm doing replacements.

Be wary of buying ramps 1.4 off ebay. When calibrating stepper motor drivers start at .7 volts and go up. You don't want to fry anything and some of the cheaper ramps start at .7 volts.

Make sure your Ramps comes with a mega board (2650) and make sure you get/buy jumpers for the steppers(you will need 3 jumpers for each stepper drivers - This allows for 1/16th steps which most 3d printers use.. I will provide pictures.

Re: Ramps 1.4 Detailed Build information

So I have been busy stripping my davinci and getting the wires ready for ramps 1.4 Here is a summary of what I had to do.

Here is a picture of the ramps kit with laser cut wood frames:

1. First I disassembled the outer plastic of the davinci leaving the metal frame so I could reroute wires to ramps, my ramps is going to be assembled outside of the davinci in a wood box.

2. I then assembled the wood laser cut box and installed the frames. I have to cut and strip the atx PSU (12v wires) and installed them into the ramps power port. Here is a link to a tutorial on doing this. You need to short the motherboard connector to allow the PSU to operate without a PC. (https://www.youtube.com/watch?v=53Lfy5oh7ho). I also installed pc fans to cool ramps in the wood box using the atx PSU connectors. Here is a picture of the ramps with some wires inserted.

3. I rewired all the wires to go to the wood box with ramps. I replaced the 300k davinci heated bed thermistor with a standard 3950 beta 100k thermistor. I also removed all the junk wires (blue wires that are on the heated bed, red wires/ yellow wires that connect to the davinci optic endstops and removed the davinci optic endstops. Here is a pic of where it current stands.

Re: Ramps 1.4 Detailed Build information

This is awesome! This is exactly what I have been looking for in order to make the jump myself to ramps. Thank you so much for doing this and keep the details/pictures coming. Any chance you could also make a suggestion on where to buy the parts. I was looking on amazon for the ramps 1.4 but it didn't look like it had good reviews.

Here is a useful markup of where wires need to go in the ramps board.

I would be very hesitant buying ramps on ebay/amazon since this one guy had the mosfet installed incorrectly by the manufacturer. This article isn't davinci related but he posts sources to legit ramp kits.

www.Makergeeks.com - The owner Josh is awesome and has all legit parts for ramps and has various ramp kits. Josh is awesome and can help you out via email with simple questions, I wouldn't bother him too much though.

Re: Ramps 1.4 Detailed Build information

Okay, been busy lately with soldering and wiring but here's a progress pic. Firmware is being worked out somewhat but had to change some pins for fan control. I'll post more details once its working.http://soliforum.com/i/?HcDLWqB.jpg

LCD is rigged temporarily. I got rid of xyz junk plastic and im going to add PETG panels.

Re: Ramps 1.4 Detailed Build information

I kept mine looking stock. mounted the RAMPS in the back with a fan mounted to the stock cover. I then printed a case for the LCD and glued over the opening for the stock LCD. On the Opto endstops I cut about a quarter inch of the from where the mounting hole was but no circuit. I then cut the existing mounts slightly to accommodate the new endstops and mounted them all in stock locations Other than the enclosure for the LCD mine still looked stock I kept the existing power supply but added my own LED strips and did away with all 3.3 and 5 volt wiring.

Printing since 2009 and still love it!

Re: Ramps 1.4 Detailed Build information

Yea I added my own led strips too. The annoying part right now is wiring is short with kit but I'll fix that in the future. Led screen is mounted temporarily just to get things working. Panels will be added every eventually. I thought about mounting in back but cooling will be insufficient and cheesy with fan. The cooling is great now but wires are annoying

Re: Ramps 1.4 Detailed Build information

I just mounted the RAMPS right behind the existing door on the back. The cut a hole for a 120mm fan glued the fan to the outside with a small hole for a wire to go through. Then put a guard over the fan. Looked nice actually and cooled very well. Ran the RAMPS on several 24 hour prints with no issues. On a RAMPS it is not actually the stepper drivers that need cooling. It is the MOSFET that controls the bed. That is notorious for shutting down under heat.

Re: Ramps 1.4 Detailed Build information

Cool thanks for sharing. Just curious how you handles the thermistor under the bed. If that thing gets loose or isn't close to bed it gets incorrect readings. I'm just using kapton tape to hold it in place

Re: Ramps 1.4 Detailed Build information

I got the code functioning last night with d9 controlling extruder fan as well. Just need to work on endstops code. I want to understand it more

Re: Ramps 1.4 Detailed Build information

Ramps is finished on marlin. I adjusted the code a bit for some other features. It took a lot of time calibrating but its possible to do.

Are the stepper motors running cooler with the RAMPS board?

As long as he set the current correctly the motors should just get warm and that is mostly from ambient generated by the bed.

Re: Ramps 1.4 Detailed Build information

Yep, they were easy to adjust. They are running a little under .5 - The y axis is a little more noisy than my x axis though. I think its because of the copper bushing vs linear bearing.
