Sprinter or Marlin Config for H1.1

Postby jasco13 » Mon Aug 20, 2012 8:48 pm

Does SeeMeCNC have a Marlin or Sprinter Config file for the H1.1? Or at least some guidance on what the proper config is?

OK I have everything working except I can't set the Z endstop to be at the max position. No matter what I set in sprinter the endstop will only work for min movement. Also if I select home for the Z axis nothing happens, but if I manually move the z-axis in the software it moves normally. Sprinter config below. What am I missing?

Code: Select all


// BASIC SETTINGS: select your board type, thermistor type, axis scaling, and endstop configuration

//// The following define selects which electronics board you have. Please choose the one that matches your setup
// MEGA/RAMPS up to 1.2  = 3,
// RAMPS 1.3 = 33
// Gen6 = 5,
// Sanguinololu up to 1.1 = 6
// Sanguinololu 1.2 and above = 62
#define MOTHERBOARD 33

//// Thermistor settings:
// 1 is 100k thermistor
// 2 is 200k thermistor
// 3 is mendel-parts thermistor
// 4 is 10k thermistor

//// Calibration variables
// X, Y, Z, E steps per unit - Metric Prusa Mendel with Wade extruder:
float axis_steps_per_unit[] = {80, 80, 3200/1.25,700};
// Metric Prusa Mendel with Makergear geared stepper extruder:
//float axis_steps_per_unit[] = {80,80,3200/1.25,1380};
// MakerGear Hybrid Prusa Mendel:
// Z axis value is for .9 stepper(if you have 1.8 steppers for Z, you need to use 2272.7272)
//float axis_steps_per_unit[] = {104.987, 104.987, 4545.4544, 1487};
//Sells Mendel with Wade's extruder:
//float axis_steps_per_unit[] = {80, 80, 6687.18,548};

//// Endstop Settings
#define ENDSTOPPULLUPS 1 // Comment this out (using // at the start of the line) to disable the endstop pullup resistors
// The pullups are needed if you directly connect a mechanical endswitch between the signal and ground pins.
const bool ENDSTOPS_INVERTING = false; //set to true to invert the logic of the endstops
//If your axes are only moving in one direction, make sure the endstops are connected properly.
//If your axes move in one direction ONLY when the endstops are triggered, set ENDSTOPS_INVERTING to true here

// This determines the communication speed of the printer
#define BAUDRATE 115200

// Comment out (using // at the start of the line) to disable SD support:
//#define SDSUPPORT 1

//// ADVANCED SETTINGS - to tweak parameters

#include "thermistortables.h"

// For Inverting Stepper Enable Pins (Active Low) use 0, Non Inverting (Active High) use 1
#define X_ENABLE_ON 0
#define Y_ENABLE_ON 0
#define Z_ENABLE_ON 0
#define E_ENABLE_ON 0

// Disables axis when it's not being used.
const bool DISABLE_X = false;
const bool DISABLE_Y = false;
const bool DISABLE_Z = true;
const bool DISABLE_E = false;

// Inverting axis direction
const bool INVERT_X_DIR = false;
const bool INVERT_Y_DIR = false;
const bool INVERT_Z_DIR = true;
const bool INVERT_E_DIR = false;

// Sets direction of endstops when homing; 1=MAX, -1=MIN
#define X_HOME_DIR -1
#define Y_HOME_DIR -1
#define Z_HOME_DIR 1

const bool min_software_endstops = false; //If true, axis won't move to coordinates less than zero.
const bool max_software_endstops = true;  //If true, axis won't move to coordinates greater than the defined lengths below.
const int X_MAX_LENGTH = 200;
const int Y_MAX_LENGTH = 200;
const int Z_MAX_LENGTH = 200;

const int NUM_AXIS = 4; // The axis order in all axis related arrays is X, Y, Z, E
float max_feedrate[] = {200000, 200000, 240, 500000};
float homing_feedrate[] = {1500,1500,120};
bool axis_relative_modes[] = {false, false, false, false};

// Min step delay in microseconds. If you are experiencing missing steps, try to raise the delay microseconds, but be aware this
// If you enable this, make sure STEP_DELAY_RATIO is disabled.

// Step delay over interval ratio. If you are still experiencing missing steps, try to uncomment the following line, but be aware this
// If you enable this, make sure STEP_DELAY_MICROS is disabled. (except for Gen6: both need to be enabled.)
//#define STEP_DELAY_RATIO 0.25

// Comment this to disable ramp acceleration

//// Acceleration settings
// X, Y, Z, E maximum start speed for accelerated moves. E default values are good for skeinforge 40+, for older versions raise them a lot.
float max_start_speed_units_per_second[] = {20.0,20.0,0.2,10.0};
long max_acceleration_units_per_sq_second[] = {100,100,50,10000}; // X, Y, Z and E max acceleration in mm/s^2 for printing moves or retracts
long max_travel_acceleration_units_per_sq_second[] = {500,500,50,500}; // X, Y, Z max acceleration in mm/s^2 for travel moves

// Machine UUID
// This may be useful if you have multiple machines and wish to identify them by using the M115 command.
// By default we set it to zeros.
char uuid[] = "00000000-0000-0000-0000-000000000000";


//// PID settings:
// Uncomment the following line to enable PID support. This is untested and could be disastrous. Be careful.
//#define PIDTEMP 1
#ifdef PIDTEMP
#define PID_MAX 255 // limits current to nozzle
#define PID_PGAIN 180 //100 is 1.0
#define PID_IGAIN 2 //100 is 1.0
#define PID_DGAIN 100 //100 is 1.0

// How often should the heater check for new temp readings, in milliseconds
// Comment the following line to enable heat management during acceleration
  // Uncomment the following line to disable heat management during moves
// Uncomment the following line to disable heat management during travel moves (and extruder-only moves, eg: retracts), strongly recommended if you are missing steps mid print.
// Probably this should remain commented if are using PID.
// It also defines the max milliseconds interval after which a travel move is not considered so for the sake of this feature.

//// Temperature smoothing - only uncomment this if your temp readings are noisy (Gen6 without EvdZ's 5V hack)
//#define SMOOTHING 1
//#define SMOOTHFACTOR 16 //best to use a power of two here - determines how many values are averaged together by the smoothing algorithm

//// Experimental watchdog and minimal temp
// The watchdog waits for the watchperiod in milliseconds whenever an M104 or M109 increases the target temperature
// If the temperature has not increased at the end of that period, the target temperature is set to zero. It can be reset with another M104/M109
//#define WATCHPERIOD 5000 //5 seconds

//// The minimal temperature defines the temperature below which the heater will not be enabled
#define MINTEMP 5

//// Experimental max temp
// When temperature exceeds max temp, your heater will be switched off.
// This feature exists to protect your hotend from overheating accidentally, but *NOT* from thermistor short/failure!
// You should use MINTEMP for thermistor short/failure protection.
#define MAXTEMP 275

// Select one of these only to define how the nozzle temp is read.
//#define HEATER_USES_AD595
//#define HEATER_USES_MAX6675

// Select one of these only to define how the bed temp is read.
//#define BED_USES_AD595

// Uncomment the following line to enable debugging. You can better control debugging below the following line
//#define DEBUG
#ifdef DEBUG
  //#define DEBUG_PREPARE_MOVE //Enable this to debug prepare_move() function
  //#define DEBUG_BRESENHAM //Enable this to debug the Bresenham algorithm
  //#define DEBUG_RAMP_ACCELERATION //Enable this to debug all constant acceleration info
  //#define DEBUG_MOVE_TIME //Enable this to time each move and print the result
  //#define DEBUG_HEAT_MGMT //Enable this to debug heat management. WARNING, this will cause axes to jitter!
  //#define DEBUG_DISABLE_CHECK_DURING_TRAVEL //Debug the namesake feature, see above in this file

Keep Scrolling down in the configuration.h file and look for endstop settings. There should be a place to change the endstop homing direction to positive (usually a 1) not negative (usually a -1)

I've only done this in Marlin and it's not completely trivial.
You have to make sure the max endstops are enabled, set the homing direction for Z.
You also have to edit pins.h and set any unused endstop pins to -1, you can also jumper the unused endstops instead.
In Advance Configuration I increase the Z bounce to 5mm, but that's not strictly necessary.
I also set endstops only used while homing, though it should make no difference.
