If i uncomment X_INVERT_DIR , i sent at ponteraface for example 10mm right ,and ti goes left. i don't want this. Directions are ok. The problem is when i sent x axis home position, at right side, it stops there and it is at 0. But it is not going left, it still going only rightby alfadex - Firmware - mainstream and related support
Hello, i have place endstop for x axis at the opposite side and i want to change it, but i can not find what ti change on firmware So, i am looking reprap from this side End stop for x axis was by wrong left. I place it right side (motor side). But i cannot find what about programming I uncomment //#define X_INVERT_MIN and when i sent home x axis ,it goes (slower than before) left anby alfadex - Firmware - mainstream and related support
In your situation , i would swap thermistor hot end, with thermistor bed, just unplug from hotend pin and plug it to bed thermnistor pins. Maybe miss operating thermistor or some connection cables. After that, try to upload the firmware, without vhange anything and test your bed.. But maybe is miss operating atmega. I close circuit inputs thermistors with 12 volts, and working everything fine eby alfadex - Printing

Every time it is stopping at a standar temperature? What temp you set, and what is it stopping temp? Try to set at a temp, that was before stoped, what happentby alfadex - Printing
config.h is like this #define X_STEP_PIN DIO29 #define X_DIR_PIN DIO28 #define X_MIN_PIN DIO0 //#define X_MAX_PIN xxxx //#define X_ENABLE_PIN xxxx //#define X_INVERT_DIR //#define X_INVERT_MIN //#define X_INVERT_MAX //#define X_INVERT_ENABLE I have done this.

Thank you all, you are right. So, i found i have x axis end stop wrong point. I change it to the other side, but i am trying with code and i can't find . I suppose something at home.c // find X MIN endstop void home_x_negative() { #if defined X_MIN_PIN TARGET t = startpoint; t.X = -1000000; #ifdef SLOW_HOMING // hit home soft t.F = SEARCH_FEEDRATE_X; #else // hit home hardby alfadex - Printing

endstops??? What you mean. Endstops for x and y are the opposite side of the motors. I don't understand what matters the endstops for the letters??by alfadex - Printing
I have pursa medel 2 ,i design with sketch up and slicer 1.0.1. 6 month , i have not found the solution for six months !!! I design this Setting fo this ,here And the result is this!!!!

I think i found the problem but i cannot resolve it. I replace 2 capacitor 3 capacitors CT1, CT2 , C19 but the problem persist. RT1 = 10k RT2 = 100k Those 2 resistors are ok. But when i measure RT2 resistors with atmga1284p on board , RT2 is below 1k . I found that on my hot end, on of the thermistor pin and one of the resistance heater was short circuit!

I have print many things,everything was working perfet until today ,i connet reprap Gen7 1.4.1 and bed temperature is 181 and hot end 404!! I cannot find where is the wrong. Those values does not change even if i unplug thermistors! If i set bed temperature to 200, it does not rise up, it stays at 181.

MAXIMUM_FEEDRATE_{XYZE} values was exactly the same I only copy STEPS_PER_M_{XYZE} and define (XYZE)_(MIN/MAX from confic.h. Nothing else.

Big mistake, DIO14 is PD6 and not PB6.Like photo . I see now PWM on oscillator. But why motor speed is so low. It is like very high micro stepping, but even if i change micro stepping nothing change And one more question ,i am trying to open SevenSwitch.sch from Github with Eagle, but says error , I tried with Kicad but nothing, .Wcich program can open those files?

I upload the new firmware but all motor speed is very low now and i cannot control micro stepping at all. And i cannot control fan speed, i sent m106 s255 but on oscilloscope nothing is moving, i have 0 V. Oscilloscope is connected hereby alfadex - Firmware - experimental, borrowed, and future

Dave tnxx , i was doing exactly those things but i was extracting to stl .When i extract to gcode ,it starts from the center, i don't know why but never minds i will extract to gcode. I want to ask something else, while z axis works perfect , now it makes so much noise and motors does not move. I adjust pololu drivers, but the same, when i put low it makes low noise and when i adjust to high itby alfadex - General
