I have a Prusa Sanguinololu 1.3 with a ATMega 1284P running Marlin and using a Panelolu2 LCD/SD reader and have experienced resets mid-print (stops and looks like it just turned on - extruder and bed heaters set to zero) while printing from the SD card. It has a dedicated 12V power supply (not ATX) . Early on, I exchanged the oscillator for a crystal to get it to work properly with my Arduino IDby Bluemetal - Sanguino(lolu)
I have now tested the printer with below combinations: 1. Marlin from 2 sources (Original ErikZalm at and T3P3 at ) 2. With and without Panelolu2 defined in configuration.h 3. Arduino 0023 (like recommended by T3P3) and Arduino 1.05 4. Bootloader from Sanguino from here ( ) and Maniacsbug Mighty 1284P ( ) Some combinations are not possible as the Mighty 1284P only works on Arduino 1.+ Thby Bluemetal - General Mendel Topics
QuoteT3P3 Hi Bluemetal What do you get when you issue M119 in your host program? that should show what endstops are open/closed. Cheers Tony Hello Tony, They report that all 3 are reported open. They still report open even if the end stop is triggered. I can see that the end stop led goes off on triggering which also means that they are powered and getting hit correctly. All 3 are ignored byby Bluemetal - General Mendel Topics
Quotebrnrd Did you enable pullups for the endstops? #define ENDSTOPPULLUPS // Comment this out (using // at the start of the line) to disable the endstop pullup resistors Yes, they are enabled.by Bluemetal - General Mendel Topics
The incorrect distances were caused by a missing comma in the steps/mm line in the firmware. That had no impact on the movement direction of x-axis and end stops. The triggering of endstops shows both on the LCD panel and on Repetier Host and with the original copied settings (all axis inverting set to false) there is no triggering. If I invert the MIN end stops (I have no MAX end stops) likeby Bluemetal - General Mendel Topics
I have a Prusa 1 (Sanguinololu 1284P) that runs perfectly with an older Marlin version from about a year ago. I am now installing a Panelolu2 ( ) for independent printing so I have followed the site recommendations to use Arduino 0023 and the T3P3 forked version of Marlin ( ). I looked at the Marlin files from a year ago and transferred all the settings that I could identify to the new T3P3 Mby Bluemetal - General Mendel Topics
