RAMPS 1.4 LCD to RAMBO mini
I have this LCD Kit that works with RAMPS 1.4 and Mega 2560
https://www.sainsmart.com/sainsmart-smart-controller-ramps-1-4-lcd-12864-led-turn-on-control-for-3d-print.html
Will this LCD work with the RAMBO mini and the MK2 software?
If not where can I get the LCD for the MK2?
Re: RAMPS 1.4 LCD to RAMBO mini
I don't think so, this one looks like the correct one but others should confirm: https://www.sainsmart.com/sainsmart-3d-printer-sanguinololu-reprap-lcd-2004-controller-adapter-sd-reader-1.html

Re: RAMPS 1.4 LCD to RAMBO mini
any way to use the MK2 without the LCD?
Re: RAMPS 1.4 LCD to RAMBO mini
Not sure if it works when the LCD module is disconnected - but you can control the printer from a computer via a USB cable.
A lot of people use a Raspberry Pi with OctoPrint installed.
I think though that some functions such as self test and calibration are only available via the LCD screen.

Re: RAMPS 1.4 LCD to RAMBO mini
If you are able to amend and compile the firmware, you may be able to get that LCD/controller to work. There are various option in Configuration.h:
//LCD and SD support
#define ULTRA_LCD //general LCD support, also 16x2
//#define DOGLCD // Support for SPI LCD 128x64 (Controller ST7565R graphic Display Family)
#define SDSUPPORT // Enable SD Card Support in Hardware Console
//#define SDSLOW // Use slower SD transfer mode (not normally needed - uncomment if you're getting volume init error)
#define SD_CHECK_AND_RETRY // Use CRC checks and retries on the SD communication
#define ENCODER_PULSES_PER_STEP 2 // Increase if you have a high resolution encoder
#define ENCODER_STEPS_PER_MENU_ITEM 2 // Set according to ENCODER_PULSES_PER_STEP or your liking
//#define ULTIMAKERCONTROLLER //as available from the Ultimaker online store.
//#define ULTIPANEL //the UltiPanel as on Thingiverse
//#define LCD_FEEDBACK_FREQUENCY_HZ 1000 // this is the tone frequency the buzzer plays when on UI feedback. ie Screen Click
//#define LCD_FEEDBACK_FREQUENCY_DURATION_MS 100 // the duration the buzzer plays the UI feedback sound. ie Screen Click

Re: RAMPS 1.4 LCD to RAMBO mini
I will try this. Although my printer is disassembled at the moment. Can I upload the firmware to the board and test the LCD over USB without a fully connected board?
Also manuals say that the LCD connectors have one/two stripes however both my connectors only have one. So not really sure where to connect these either...
Re: RAMPS 1.4 LCD to RAMBO mini
The stripes referred to are black marker pen at each end; not the red stripe along the length.
The red stripe should go to pin 10 at each end. Finding out which socket goes into which plug is trial and error; getting it wrong should not cause a problem.
The processor on the RAMBo can be powered via the USB cable so you can upload the firmware without other power, but the LCD may require power from the PSU.

Re: RAMPS 1.4 LCD to RAMBO mini
I can hook up my PSU if necessary. But I'm a bit confused and don't wan't to blow up my RAMBO.
I have a PSU with two negative and two positive wires (exposed wires) but I don't have any type of Molex connector Like in the manual... http://manual.prusa3d.com/Guide/8.+Electronics+assembly/110#s1716
So i'm not too sure how to connect my PSU where do the negative's and positive's go?
I saw this
So two separate positive and negative sets from the PSU go into this connection (to provide motors and heatbed a separated power source) correct?
Also I could get an appropriate connector to clean up my wiring, what type is it to use?
Thanks!
Re: RAMPS 1.4 LCD to RAMBO mini
Having tried this recently, there are problems in the firmware that may need fixing out before you can try it. As it stands, the firmware won't compile if you enable the fall graphic controller. The SD card driver gave issues I seem to remember for a start, but even with that disabled there were other issues. While the standard firmware compiled OK it's possible I didn't have the Arduino environment set up as was needed.
Might be worth seeing if you can get the firmware to compile first.
Re: RAMPS 1.4 LCD to RAMBO mini
I think this is the connector: http://shop.prusa3d.com/en/mk2-spare-parts/125-rambo-mini-heatbed-connector.html
You should have some from the original printer and/or RAMBo. PSU power needs to go to input B for processor.

Re: RAMPS 1.4 LCD to RAMBO mini
Well actually I think it's sounding like it will be a hassle to try and use this LCD.
Will be much easier if I just buy the right one.
the right one?

Best thing is to contact support using live chat to see if they will sell you a replacement.

Re: RAMPS 1.4 LCD to RAMBO mini
It looks like the RepRapFullgraphics display. I have a similar one running on a Rambo Mini (not a Prusa MK2) running the RC8 Marlin Firmware. The biggest problem I found was the orientation of the two cables to the LCD display, I had to connect them the opposite way around on the Rambo Board.
You may have to edit these lines...
//#define ULTRA_LCD //general LCD support, also 16x2 <--------------Disable
#define DOGLCD // Support for SPI LCD 128x64 (Controller ST7565R graphic Display Family) <--------------Enable

Make sure you install the U8glib in to your Arduino IDE and then upload the firmware. If all goes well it should work. There are some features that may or may not have been removed from the Prusa Marlin Firmware. Have a look in in the Configuration.h & Configuration.adv.h files. As far as I can tell the Prusa Configuration.h has been renamed to Configuration.prusa.h or something like that, I don't have the firmware to hand.
Re: RAMPS 1.4 LCD to RAMBO mini
The only problem is I want to use the MK2 software with all the new enhancements, like the probe and centering
Re: RAMPS 1.4 LCD to RAMBO mini
Sure, just edit the Prusa Marlin Firmware and upload it to the MK2 and you should be good to go. Check the LCD cable connections on the RAMBo as I mentioned.
