Guys, I’m having noob issues here trying to test Arduino/Ramps with Full Graphic LCD 12864 and am planning to also test the stepsticks for the steppers (DRV8825)… I managed to compile/upload Marlin with u8glib and 12864 LCD support but am getting Err: MINTEMP and turning the wheel doesn’t do nothing.
What’s next?
You need to connect your thermistors…
I just want to test few parts and need a workaround to skip this… I’m sure I’ve seen it somewhere arghhh
Set the min temp in the firmware to 0?
The error isn’t very explicit…
#define HEATER_0_MINTEMP 5
#define HEATER_1_MINTEMP 5
#define HEATER_2_MINTEMP 5
#define HEATER_3_MINTEMP 5
#define BED_MINTEMP 5
which one?
ok, first one did it … now I get 3D Printer Ready …
next: wheel registers in reverse and I can’t find the “#if defined (REPRAP_DISCOUNT_FULL_GRAPHIC_SMART_CONTROLLER)” section to add the “ENCODER_PULSES_PER_STEP” to change that behavior…
Ok, done it. Man have they moved things around… it is useful to load all Marlin files in Notepad++ and do a global search…easier than the Arduino IDE UI imho.
So “#if ENABLED(REPRAP_DISCOUNT_SMART_CONTROLLER)” statement is in the pins_RAMPS_14.h file now and I had to reverse the BTN_EN1 and BTN_EN2 (originally 31 and 33, now BTN_EN1 is 33 and EN2 is 31).
Next will be stepsticks… hope I don’t fry anything :-s
Good luck
I had a bunch of DRV8825 and apparently out of 5 3 are working ok. I knew I had some broken ones so at least now I know. Motors moving but will have to calibrate voltage because the feeling of the spindle rotation and their sound is slightly different. But tomorrow that :).
