With these settings we were able to compile the settings. Some TMC stepper drivers can detect when they bump into something that causes them to stop moving. Only integer values >= 1 are valid for these settings. // Default behavior is limited to Z axis only. This uses a very low frequency which is not as annoying as with the hardware PWM. The click input can either be directly connected to a pin (if. Part 7. @section homing. With this option enabled the other required settings are automatically configured (so there’s no need to enter servo angles, for example). Correct the wrong arc g-codes sent by SkeinForge when using Arc Point as fillet procedure. Disable to save PROGMEM. You can also enable LCD_BED_LEVELING to add a “Level Bed” Menu item to the LCD for a fully interactive leveling process. The movement is done at a reduced motor current to prevent breaking parts and promote skipped steps. Level your X axis by trying to move the Z axis past its physical limit. #define ADVANCED_PAUSE_PURGE_LENGTH 50 // (mm) Length to extrude after loading. Nonetheless the next step of configuring the SKR V1.4 is a few lines in the pins_BTT_SKR_V1_4.h file, for those wishing to use the SD Card EEPROM emulation, or are using Marlin firmware version under 2.0.5.3. Use blower fans to keep air moving and use a Dew Point Calculator to check your local dew point. To solve this issue, this option sets the number of milliseconds a hotend will preheat before Marlin starts to check the temperature. Adaptive Step Smoothing increases the resolution of multi-axis moves, particularly at step frequencies below 1kHz (for AVR) or 10kHz (for ARM), where aliasing between axes in multi-axis moves causes audible vibration and surface artifacts. Add an M73 G-code to set the current percentage. However, control resolution will be halved for each increment; at zero value, there are 128 effective control positions. #define Y_HOME_BUMP_MM 5 Take a copy of your `M503` output to save your current printer settings. On delta machines, all the max plugs should be used. For the 2.0.x branch of Marlin, different constant names are in use, and a different strategy is used (more simple for setting up). These values can be overridden using the M145 command or the Control > Temperature > Preheat Material X conf submenus. Using boards.h as a reference, replace BOARD_RAMPS_14_EFB with your board’s ID. This saves a space in the command buffer and reduces overhead. If the pins are able to do hardware PWM then a wide range of colors will be available. In practice with a well-calibrated machine this is not an issue and using open loop is a major cost saving with excellent quality. Turn off after the print has finished and the user has pushed a button. Today, I'm going through all the Marlin 2.0 configuration steps before we can compile the firmware for the SKR 1.3 and then we'll have to do some fine tuning of the stepper motor settings to get sensorless homing to work on this printer as well. Importantly if you using a BlTouch or probe, search for and enable Z_SAFE_HOMING. If you get false positives for “Heating failed” increase WATCH_TEMP_PERIOD and/or decrease WATCH_TEMP_INCREASE. Set to 2 for a fast/slow probe - the second probe result will be used. Above the given Z height, leveling compensation will no longer be applied. Cartesian is the simplest, applying each stepper directly to an axis. The dual endstop offsets can be set at runtime with M666 X[offset] Y[offset] Z[offset]. #define FILAMENT_CHANGE_SLOW_LOAD_LENGTH 0 // (mm) Slow length, to allow time to insert material.

Whenever an SD print completes the LCD Menu will open with the same file selected. Now we come to the thermal settings section of the Marlin firmware where things get a bit more complicated, however, we don’t need to touch the complicated stuff to get the printer up and running. Marlin is a huge C++ program composed of many files, but here we’ll only be talking about the two files that contain all of Marlin’s compile-time configuration options: These two files contain all of Marlin’s build-time configuration options. The Z offset should be specified as exactly as possible using a decimal value. This is useful to prevent the head crashing into bed mountings such as screws, bulldog clips, etc. The default values are based on a E3D V6 hotend and the nozzle to extruder gear distance of a Prusa MK3 extruder, so if required you have to modifiy those to your extruder/hotend setup accordingly. If jerk is too low, the extruder will linger too long on small segments and corners, possibly leaving blobs. Enable this option to suppress the warning given in cases when reduced accuracy is likely to occur. For other configurations set these values appropriately. #define Z_SAFE_HOMING_Y_POINT ((Y_BED_SIZE) / 2) // Y point for Z homing when homing all axes (G28). From this point on, the machine “knows” its position by keeping track of how far the steppers have been moved. Adjust the relavant settings to your specifications for use with either PARKING_EXTRUDER or MAGNETIC_PARKING_EXTRUDER. #define MAX7219_NUMBER_UNITS 1 // Number of Max7219 units in chain. I know that G32 is just for auto leveling. #define HEATER_2_MINTEMP 5 If you have SRAM to spare, this option will multiply the resolution of the bilinear grid using the Catmull-Rom subdivision method. By that logic you should implement Homing backoff after probing. After the final adjusted firmware upload, and bringing the sensor up, I see that the extruder pushes the bed down a bit when I auto home and then the LCD screen says probing failed. //#define FILAMENT_UNLOAD_ALL_EXTRUDERS // Allow M702 to unload all extruders above a minimum target temp (as set by M302), #define X_SENSE_RESISTOR 91 // (mOhms), #define X_MICROSTEPS 16 // Number of microsteps, #define HOLD_MULTIPLIER 0.5 // Scales down the holding current from run current, #define INTERPOLATE true // Interpolate X/Y/Z_MICROSTEPS to 256.
