How to modify a standard RAMPS 1.4 to work with Arduino Due?

Interesting thread here. I have a ramps-fd I got cheap off ebay and am considering modding it to be a bit safer (pullup resistors on fet drivers and on board 3.3 supply regulator). For me the issue of the fet Rd is a moot point since I am using a SSR to drive my heat bed. I built my own heat bed by gluing sand resistors to the bottom of an aluminum plate (JB-Weld), and I run the bed off of 48v AC. The relay switches the primary of the stepdown transformer that drives the bed (surplus tranny from an old amplifier).

Hi guys, after the ramps mods,I have flash the Marlinkimbra4due firmware [github.com] but repetier-host report this error message:

I think I made all the mods correctly.

Try changing transfer protocol to ASCII, or lower the baudrate.

With RAMPS 1.4 now selling for as low as $5 incl shipping, I think it is a pretty interesting mod. Did anyone put together a web page describing the mods? If not I might do that.

I am just doing a KiCad version of RAMPS 1.4.2, so could also do a schematic for a 3.3V version.

Would it be possible to convert RAMPS 1.4 into SMART RAMPS (aka RAMPS 1.4.1)? I was looking at the schematic for version 1.4.1 (found in wiki) but I did not see much difference comparing to 1.4.

The best way to describe the changes I found them at Budget swap 32-bit electronics (it is in russian but works ok with Chrome for the translation). Although in this page it is described to build another circuit for MOSFETs instead of replacing them with others. What is also included in the link is taking care of SPI pins for the card reader, I did not see this in the current thread.

IMO, so-called SMART RAMPS is just as dumb as the original. It still has no on-board 5V regulator to power GLCDs without overloading the 5V regulator on the Arduino, and it still has a poorly-chosen bed heater mosfet. What a wasted opportunity.

You never tire of knocking other people's work do you?

It seems you post just to get another plug in for your products.

If you've nothing constructive, please go away.

I am offering constructive criticism, because RAMPS has been stuck in a rut for years and badly needs to be improved. I don't knock other people's work when it is good.

Poor electronic design really irritates me. But when a design has more than one well-known flaw, yet none of them are addressed when the design is revised, that is IMO inexcusable.

The SMART tag on RAMPS 1.4.1 is a total joke. That revision is nothing more than a cost reduction exercise for automated manufacturing. It would have cost very little to add a 7805 voltage regulator to provide enough power for GLCDs, and almost nothing to specify a better heated bed mosfet such as the IRLB8743. The published information I found doesn't even say what voltage rating the 100uF capacitors are meant to have, so we can expect that nearly all 1.4.1 boards will use 16V ones - meaning that 24V operation will continue to be impossible.

I appreciate that Arduino/RAMPS appeals to the budget market that more advanced electronics can't yet address because Chinese Arduino/RAMPS clones are so cheap - but even the budget market deserves an improved RAMPS (or something else that isn't a lot more expensive).

I am offering constructive criticism, because RAMPS has been stuck in a rut for years and badly needs to be improved. I don't knock other people's work when it is good.
Poor electronic design really irritates me. But when a design has more than one well-known flaw, yet none of them are addressed when the design is revised, that is IMO inexcusable.

The SMART tag on RAMPS 1.4.1 is a total joke.

My first post over here being very new on 3D printing, and will start with constructive criticism

dc42, I would assume you are not alone over here designing electronic HW, I am doing it too... Instead of criticizing, much more constructive is to provide advises for a better way modification, at the same time you may point out on how it is done in your work. You will gain much more on this path than blindly criticizing others work as bobc mentioned and on which I am fully agree... RAMPS possible is not ideal product, but it have the most important characteristic, it is cheap and already correctly sized platform, it is mechanical plug&play fit on Due board. The modification is very simple and possible to be done in a number of ways, adding mods is easy, who say you cant do small stand-alone bred-board for heater only? Let's be serious, replacing one component with another more suitable for the job is not a rocket science, as well as adapting 3.3 logic level to 5.0... Plug in DRV8825 instead of A4988 and voila, half of the work is done!
I do agree not every one could do it correctly, as well as not every one is having experience on HW design, that's why they seek for advise from people who know this, like you... If you are willing to help them, that would be just great, just do it without annoying morality lecturers on what is correct and what is not

Parasole, read my post FULLY. I DID say how the design could be improved at very little cost, two sentences after the ones you quoted.

Hi everybody! I know this is old but I recently bought a used K40 laser machine and I'm converting it to a bigger area and a new controller. As I had an Arduino Due laying around, which I was afraid to use on a 3D printer with the FD, I decided to use it on a laser because there was no danger of a heating MOSFET turning on by accident. Simply there are no heaters. So, in short, thanks to this mod I was able to plug a Ramps 1.4 modified and uploaded a Mk4Duo with a laser configuration and an LCD screen to control it. It wasn't easy because it kept giving me errors of compilation but I managed to solved them all, I hope. At least it compiles. Thank you all for your contribution.

Following up on this old thread - I am a bit puzzled by the jumper behind the reset button. The picture from the bottom indicates, that pin "3" has been "lifted", and no longer connects to the Due .. But there is an extra long pin at number 2 - as it looks as if the jumper is connected at this one, but it also connects to the arduino due.

I just ordered an extra RAMPS, a couple of DUE and new mosfets from China - in order to try to see if it would be possible to get anything up and running. If more details can be found/described within the next 4 weeks (delivery-time from China ;-)), then I would really appreciate it.

In the meantime I will try to look a bit a RADDS - even though I find some differences between the schematic and the PCB/connector layout (http://www.dr-henschke.de/RADDS_due.html - there is no IC2 on the schematic) ...

Correct pin 3 has been lifted, this disconnects the "5v" line from 5v. (which is still on the due)

Top of PCB is being used to connect pin 3 tracks to pin 2 (3.3v)

The next image shows it clearly

Excellent - then I just have to wait for my Due and extra RAMPS to arrive from China....

Next step - Marlin4Due - and maybe check differences between Marlin4Due and the current 1.1.4 of Marlin...

Hopefully Marlin 2.0 will support the modified RAMPS 1.4 board as well .... :-)

I know I'm a little late to the game, but I figured I might as well try something a little different.

Modifications are great and all, but there seems to still be an issue with running 5V systems on 3.3V, and while I cant verify, I have a feeling that pulling too much power out of the pins for the FETs and Servos is a major issue.

I put together a board that goes between a standard RAMPS board and a Due, and uses the 12V input from the RAMPS, stepped down to 5V, to drive the heater and servo pins. It also adds the EEPROM, regulates the endstops, and divides down the thermistors.




Github is here: [github.com]

Still working on testing it, and I do want it to be able to handle an LCD screen, but I've got to figure out which pins need to be regulated down (just the encoder one right?), and figure out what's up with SPI on the due in order to get the SD card working.

Makers gonna make, but I'm trying to see if I can put together a plug and play solution to making a due work with a stock 5V RAMPS.

Any comments or things that can be fixed?

Hi.
Can someone if is possible to use the Ramps 1.5 with the Arduino Due? The new Ramps have different mosfets from the version 1.4.
Regards.

Probably not. I have yet to see a Eagle source file for it, but because its set to work with the mega, the ADCs are all for 5V logic.

In addition, there's the critical issue that the Mega and due have different pinouts.

Nice work.
Thought about doing the same but aint had the Time recently.
Hope you keep us Updated.

@SZiv

Nice

I was envisioning something similar but for the driver modules, one row of connectors for normal pololu type and another for tcm2130 with spi and cs lines all done on on pcb..

But as a replacement to the ramps

The RAMPS has is problems, but when you get right down to it, it has everything necessary to run a printer, and because it's mass produced, its dirt cheap.

I cant say the RAMPS is my favorate board, but once you start adding ICs and the size necessary for all those drivers, it starts getting pricy. The goal here is to make something cheap enough to be an upgrade to an existing RAMPS system to 32 bits for an additional 20 bucks or so (10ish for the due + 10 for RAMPSDC).

That being said, the due is on the way out in terms of power. yeah it better then a RAMPS, but the future of 32 bit boards is looking like the ESP32. which has 10 times the processing power of the due, and is cheaper and smaller, and development work is already being done to port marlin to it.

I've got a first set of the RAMPSDC boards in, and I'm working on assembling them if I can find the time. Once I verify they work, I'll do a final github push for clerical purposes, but I've already started a board for the NodeMCU ESP32 which is probably where most of my focus will be.

Hello everybody.
I have done this mod for ramps1.4 + due and the truth has worked well with dis types of firmware: kimbra marlin and repetier v0.92.8
My problem is this: now I want to add a step expander, and look at the following web
[reprap.org]
and in all those that this one has taken me, I have not managed to make it work.
Can somebody help me
I'm using marlin kimbra and repetier, I do not care at any given time
Greetings and thank you

Hi isralgs,
what kind of expansion board do you have?

Hi MrAlvin
i found the solution.the communication pins are not posiible to use.
Thank you very much for your attention

Hi guys,

I made my Ramps4due, the configuration I'm using is with RepRapDiscount Full Graphic Smart Controller, I2C EEPROM, Dual Extruder, Hetabed, PWM fan controlled by external board made by me.

I'm testing it on my Geeetech I3 Pro B that I normally use with full satisfaction with a GT2560 and A4988 drivers with Vref set to 0.8v).

I would like some advice on which stepper drivers to use with the Ramps4due, A4988 or DRV8825?
I did some tests with both:
With the drv8825 set to 1/16 and vref to 0.8v the rotation of the stepper motor is very rough and noisy, not really the best, I have not tried with 1/32. With the A4988, same setting 1/16 and 0.8v, it is much better but I noticed a considerable heating of the heatsinks, more than what happens with the GT2560.
I also noticed that isn't possible to set value above 0.82v, will be for 3.3v?

I forgot, the firmware I use is Mk4duo 4.3.6 with some adjustment.

What do you suggest?
Thanks

Hi all.

Built myself one too It's running fine under Marlin 2 but I'd like to experiment with it. Has anyone tried to install ReprapFirmware on a Due? Is it possible to use Due+RAMPS and RRF? Any pointers where to start much appreciated.

I do a build of RRF for Arduino Due + RADDS. Unfortunately the main user who was testing the RADDS build of RRF damaged his RADDS and decided to replace it with a Duet. So although I have released another RADDS build of RRF since then, I don't know whether anyone is testing or using it.

You could adapt that build for Due + RAMPS by modifying the Pins_RADDS.h file and recompiling. Someone already did that for the RuRamps board and for another 3.3V RAMPS derivative.

Links:

Latest release is at [github.com]. I also have a build using the RTOS kernel.

... I'm running some machines with RADDS or compatible 4-axis-drivers, actually with Marlin4Due, but regularly modifying the firmware or searching for alternatives -- so could test your RRF

Thanks for the offer! The firmware binary for Due/RADDS is file RepRapFirmware-RADDS.bin at [github.com]. I don't know how some pins are allocated for RADDS (e.g. endstop inputs), but the pin allocations are defined in file [github.com].

To install the firmware, press the Erase button and use Bossa or Bossac to upload the firmware binary through the program port. To talk to the board via USB, preferably use the program port because it has proper flow control.

You should be able to use the configurator at [configurator.reprapfirmware.org] to generate the configuration files to put in the /sys folder of the SD card. I suggest you select board type Duet 0.8.5, which should be close enough.

Some documentation links:

[duet3d.dozuki.com] (to better understand the configuration and homing files)
[duet3d.dozuki.com] (index of firmware-related pages)
[duet3d.dozuki.com] (to switch into laser mode, because I know you are into that)

For help, drop me a PM or ask on the forum at [forum.duet3d.com].
