In configuration.h the default values for acceleration and jerk are insane. Z Axis movement speed: 16.7mm/s. The current default values are: Why does Marlin by default change the print speed when turning the LCD dial? * When changing speed and direction, if the difference is less than the * value set here, it may happen instantaneously. #define DEFAULT_MAX_FEEDRATE {500, 500, 5, 25} // (mm/sec) #define DEFAULT_MAX_ACCELERATION {9000,9000,100,10000} // X, Y, Z, E maximum start speed for accelerated moves. I know there are default max feedrates but I'm not seeing a default set feedrate. M204 - Set default acceleration: S for print and retract, R for retract moves, T for travel moves (M204 S3000 T7000) in mm/sec^2. Discussion. You can also move the printhead to a position by using the G1 command with the desired position along the axis in mm and the desired speed in mm per minute, so that’s 60 times the speed you’d set in your firmware. ... Baudrate is the speed of the serial connection, by default 115200 or 250000. I recently upgraded my prusa i3 firmware to a newer version of marlin. X/Y Axis movement speed: 120mm/s. @thisiskeithb - tagging since you contributed the original profile for this printer Description Stock Marlin 1.1.9 with Ender 3 defaults results in fairly violent homing, causing the X and Y axis end switches to bottom out. Homing feed rate. It is the total number of axis (3) plus the number of extruders (1). Higher speed means information can be transferred faster between PC and This makes it very hard for someone who has never configured Marlin before to set sane values. I’ve always considered it weird that on the top level of the marlin LCD, if I turn the dial, I can fine adjust the speed of printing. Movement settings Define the number of axis. Print quality was no different than 60mm/s. When the z axis homes , it touches the endstop and moves up and homes again , but when moving down to home the second time , it moves extremely slowly , it takes 1 minute to hit the endstop again. Outline underspeed: 40%. Line 330 Onwards. Marlin is one of the more popular firmwares available. Let us help you find the perfect settings. I personally have spent the past six months hunting down extruder issues only to find out the problem was my E acceleration was way too high. */ # define DEFAULT_XJERK 10.0 # define DEFAULT_YJERK 10.0 # define DEFAULT_ZJERK 0.3 # define DEFAULT_EJERK 5.0 Stock Ender 3 will handle that no problem, I sling around a 1/4" thick bed at 1500 accel no problem at that speed. #define NUM_AXIS 4. Default printing speed: 100mm/s. A firmware is the software which converts machine instructions (gcodes) into actual movements. A typical line of (depositing) G-code seems to set a maximum speed (F), a new position to move to (X, Y, Z) and a new extrusion distance (giving a filament distance for the move).The F is common for the line of code, and I understand gives a maximum for the XYZE combined speed.. My question is: "How is the extrusion rate synchronised to the movement distance and speed?" So set a maximum speed and do a test move along an axis, but make sure your host doesn’t artificially slow it down. Oftentimes in Marlin, speed or acceleration are expressed in [mm/s] or [mm/s2] but the feed is expressed in [mm/min]. When I turn on the printer, connect to Pronterface and issue a G1 X10 y10 z10 E10 command everything works fine. How do you set the default feedrates for the motors in Marlin. Example. Set max acceleration in units/s^2 for travel moves (M202 X1000 Y1000) M203 - Set maximum feedrate that your machine can sustain (M203 X200 Y200 Z300 E10000) in mm/sec. Movement variables: M202 - UNUSED IN MARLIN. Solid Infill Underspeed: 60%. Check the default values in the Marlin as supplied with your machine and use these to start with. To get the most out of your Ender 3 (Pro/V2), print speed is a key factor. Support structure underspeed: 80%. This is the moving speed of the axis when homing in [mm/min].
