Hi, people,
I would like to test all my motors and movement before installing everything on the printer.
So I put together the RAMPS 1.4, stepper drivers and 3 stepper motors, installed and roughly configured the Marlin so I could play a bit...
Can I somehow make Pronterface think that thermistor readings are ok so I could move motors in any direction, not only to "home" ie one direction until endstop? Or should I reconfigure the firmware? What would be the quickest way?
#define HEATER_0_MINTEMP 0 //#define HEATER_0_MINTEMP 5 #define HEATER_1_MINTEMP 0 //#define HEATER_1_MINTEMP 5 #define HEATER_2_MINTEMP 0 //#define HEATER_2_MINTEMP 5 #define BED_MINTEMP 0 //#define BED_MINTEMP 5

Another question: I had a problem turning my z-axis motors. They would only make noise and not move. I tried swapping the drivers, the motors, and found that all components are healthy and fine, just the z-axis on my ramps board seems "dead". So I tried setting it to 1/16 microstepping and the motors started turning. Anyone knows where the catch could be? I didn't change current settings on stepper drivers or anything. z-axis doesn't even work with only one motor attached, if not in microstepping mode.
#define DEFAULT_AXIS_STEPS_PER_UNIT {100, 100, 4000,600}and figured that's waaay to many steps, and as such - waaay to fast. So I installed jumpers under drivers on my ramps to 1/16th microstepping, and the motors all turn smoothly and the movements are correct. Now I'm able to play with my machine and test it without heatbed and extruder.

I can recommend using pronterface/ printrun for testing. It has nice arrows and such to control the printer.Quote

figgured it out, should anyone have similar questions, I give answers:

None of the assembly instructions say explicitly that you should use microstepping, and as a first time machine builder, how should I know? Then I came across this:
#define DEFAULT_AXIS_STEPS_PER_UNIT {100, 100, 4000,600}and figured that's waaay to many steps, and as such - waaay to fast. So I installed jumpers under drivers on my ramps to 1/16th microstepping, and the motors all turn smoothly and the movements are correct.
