Marlin on Rostock+RAMBo+LCD

[AlexBorro]

Has anyone tried Marlin on Rostock + RAMBo + LCD ??

I could not get the LCD working. I don't now what is different on RAMBo from other boards like RAMPS and RUMBA...

Cheers.

Alex.

Yes, I had it working with an older version that I got from SeeMe or something. If you get the latest branch I know for sure that the LCD works (it works on my Ultimaker with RAMPS, I would assume the pin assignments are correct for RAMBo, unless someone got lazy...). Are you using the latest firmware, is the board assigned to 301, is the line for RepRapDiscount LCD Controller uncommented? if all these are done correctly it should work, if not then the pins probably aren't assigned correctly.

Hi Mike,

I have tried the latest version from github.. seems something is wrong in the RAMBo LCD pins config.. I'm trying to figure out if someone has solved it before start scrubbing the code.

Cheers!

Alex.

According to the Wiki (and my pins.h file) these should be the pin assignments

Not sure if this matches yours, but it doesn't hurt to check just in case. If not, then good luck finding a solution, I'll be looking a bit too

https://github.com/johnoly99/Marlin-for ... kmax-rambo also maybe check this out, its an older version, but from the looks of it it has a working LCD configuration...

[AlexBorro]

I tried this older version with no success... I guess something has changed in last RAMBo version.

Cheers.

Alex.

Do you know which version it is exactly? is it 2.0? I didn't think that the MAXes were shipping with it yet... did the pin assignments differ from the ones I posted?
