Re: 128x64 lcd does not work with mks tinybee! - 6 months ago
Marlin can not cause your electronics to whine in protest like that This is a hardware issue Look harder at your electronics Show a picture of the back of your LCD and cables and controller, I want to check you actually have exp1 going to exp1 and exp2 going to exp2 and to see what cable orientation you are using.by Dust - Firmware - Marlin

Re: 128x64 lcd does not work with mks tinybee! - 6 months ago
Your using old code "#define CONFIGURATION_H_VERSION 02010000" Firstly check your lcd and your controller gnds are connected. Ie unplug from power and usb. Check there is electrical conductivity from the on controller sd card slot metal can to the on lcd lcd slot metal can. If these are not connected your LCD cables are not correct. Note there are two cables you must plug Exp1 on motherboaby Dust - Firmware - Marlin

Look at configuration_adv.h /** * Fan Fast PWM * * Combinations of PWM Modes, prescale values and TOP resolutions are used internally * to produce a frequency as close as possible to the desired frequency. * * FAST_PWM_FAN_FREQUENCY * Set this to your desired frequency. * For AVR, if left undefined this defaults to F = F_CPU/(2*255*1) * i.e., F = 31.4kHz on 16MHz microcoby Dust - General

You don't rename the required directory name, ever There are 3 different versions of this display (have requested they add the additional data below to this page) All 3 require their custom files in different formats and use different directory names on the sdcard First is DWIN uses the directory DWIN_SET second is DACAI and uses the directory private The 3rd, is a VIEWE and does not useby Dust - Firmware - Marlin

I just tried my SK6812 (NEO_GRBW) on a ramps with current marlin bugfix 2.1.x and it works as expected #define NEOPIXEL_LED #if ENABLED(NEOPIXEL_LED) #define NEOPIXEL_TYPE NEO_GRBW // NEO_GRBW, NEO_RGBW, NEO_GRB, NEO_RBG, etc. // See #define NEOPIXEL_PIN 4 // LED driving pin #define NEOPIXEL_PIXELS 8 // Numberby Dust - Firmware - Marlin
Re: Neopixel RGBW issue - 6 months ago
You don't play with HAS_WHITE_LED,this is set in code as needed. "I can get the RGB (NEO_GBR) colours to work perfectly (when 'HAS_WHITE_LED' is not selected), they cycle correctly when the board is powered up (self test), and I have full control using the gcode M150 commands." this should not work. You have told it you have G B and R leds, it doesn't know about the 4th led Ie you haveby Dust - Firmware - Marlin

Only invert endstops if M119 says triggered when open and it says open when you manually hold the switch down. Ie this need inverted If it is stuck on open or triggered, this is something else, not endstop inversion.by Dust - Firmware - Marlin
Re: Board questions - Creality 4.2.7 - 7 months ago
on the creality 4.2.7 the endstop are X-,Y- and Z- by default because the config file asks for homing to min endstop. They are defined as #define X_STOP_PIN PA5 #define Y_STOP_PIN PA6 #define Z_STOP_PIN PA7 so are used as min or max as requested by the homing direction in the Configuration fies (in marlin anyways)by Dust - Mendel90
Re: Btt Skr pro Cnc homing direction - 7 months ago
you don't describe your Y axes enough... Is your Y axes a bed slinger like most 3d printers, or a fixed bed in the Y direction? If it is a bed slinger then an endstop at the back is the min Y position If Y is fixed then a endstop at the back is a Y max positionby Dust - Firmware - Marlin
Re: Creality 4.2.7 LCD Screen - 7 months ago
Not easily the ramps 128x64 lcd requires 2 * 10 pin connectors the creality 4.2.7 only has 1 10 pin connector the 4.2.7 is designed for creality displays. the color tft with encoder, the colour tft with touch. (both are serial devices) and the CR10_STOCKDISPLAY, which uses 1 10pin and doesnt have a sd on the display You would need to make up a custom cable to emulate a CR10_STOCKDISPLAYby Dust - Controllers

Re: Can't comunicate with mega2560 with ramps attached - 7 months ago
@gibrie There is nothing like that on ramps. usb plug -> usb converter chip -> atmega2560 uart 0 port With no external power applied to the ramps, 5v is taken from USB power Get yourself a usb power meter. A bare ramps on a mega takes about 0.071A and the 5v line should not drop. I suspect you either plugged the ramps in badly (missed pins, pins out by one. etc) or they have shortsby Dust - RAMPS Electronics

Re: Trouble with flashing Marlin 2.1 on MKS board via Arduino UNO as programmer - 7 months ago
Personally this is the wrong way to do it I would do the following. Use arduino ide to put a bootloader onto your controller via the uno running Arduino as ISP then use platformio as it was intended to connect to your controller via usb to the bootloader.by Dust - Firmware - Marlin
Re: Trouble with flashing Marlin 2.1 on MKS board via Arduino UNO as programmer - 7 months ago
Also the environment your using for you board needs updating to use Arduino as ISP (default expect standard bootloader over usb) upload_protocol = stk500v1 ; each flag in a new line upload_flags = -P$UPLOAD_PORT -b$UPLOAD_SPEED ; edit these lines upload_port = SERIAL_PORT_HERE upload_speed = 19200by Dust - Firmware - Marlin
