Is it possible to use the Panelolu2 for RAMPS and Printrboard on the newer Solidoodle 2 board? From what I have read the new board is basically a Printrboard rev-e with a few modifications, correct? If that is the case is it possible to use the second generation Panelolu on the board? Are there enough headers for the new board?
Thanks, Hunter
Is it possible? Yes.
You need to solder in the headers as SD decided to save money and not buy them.
While the LCD will definitely work, there is contention on getting the external SDcard to work.
I have yet to find anyone who has done it with a Solidoodle printrboard.
I thought I had read somewhere that it was as simple as changing one line in configuration.h but you had to start prints from the computer.
I have documented in a couple of threads my results of working with the Solidoodle Printrboard. When I could get the firmware to see the sd card, any attempt to print from it resulted in the machine stalling part way through the print. Always stalls in the same place (for a specific gcode file) and many gcode files were tested (each file had a different stall point, but would stall in the same place for repeated attempts).
I have a clone geeetech printrboard that I used to get the sd card to work. No problems. The problem is either unique to the Solidoodle printrboard in general, or just to my board alone. I have asked many times if anyone else has had any different experience and I have yet to see a reply.
So. There you go. I have one bad experience that cannot be resolved. This opens up the conversation for someone to reply with more positive results. I hope they do.
Am having a bash at putting a reprap "Discount Smart Controller" onto a Printrboard Rev E Solidoodle 2.
Not much joy so far, but kind of early days. The kit I purchased had a "Teensylu" adapter, which required putting the Exp 1 header pins in (and "gently encouraging" the connector to plug in to both the Exp 1 and ICP pins.
Downloaded the Ardunio as per the "Update Firmware" wiki, but there was no file at the "firmware download" link. Came back to the firmware threads and found the Marlin site, downloaded their lot.
Updated the motherboard, thermsistor, heat settings, and uncommented the "#define REPRAP_DISCOUNT_SMART_CONTROLLER" line, whereupon the code wouldn't compile due to a "BLEN_C undefined" error (among others). Adjusted pins.h to add Newpanel and ultipanel definitions under motherboard 81, and got a clean compile which I then uploaded to my printer.
Rebuilt, reconnected and powered up, and LCD is blank. Printer still connects to host (although my printer host PC has now died with all my customer settings, the biarch), and heats and moves (no prints as yet until I can recover my settings).
Will have a review of the various "adding LCD" threads, as there are about three different sets of pin values I have found so far for the Ulitpanel / newpanel, so see how we go from there.
The latest RH software looks way more flash, but need to get the old PC up and running first (or migrate the printer to the office with the new PC and start again until the SD card works).
Will review Hazer's firmware adjustments from LCD efforts in the marlin thread, and start again with clean / latest Ardunio and Marlin installs.
Update:
After tracking what the adapter was up to, discovered it was putting feeds into dead pins, and dropping other pins out completely. Going to wire up an "adapter" of my own, and try the pin assignments of others here.
Tried (as a check) onboard SD card enabling, no joy there (which was expected).
Will try re-locating Y-stop to the e-stop (have soldered in all header pins now, so can play about without having to remove board again). Then will try onboard SD again.
