Re: Problems Compiling Marlin on RAMBO 1.3 - Today

In marlin it sets the following as as default contrast #define _LCD_CONTRAST_INIT 140 But this can be update with M250 Is this what your changing?

"and the correct setting is NO (normally opened)." no not really. normally closed endstops are the standard, as it means that when you break a endstop wire (or unplug it) the endstop is triggered, vs just crashing the machine into the end of travel when the endstop is disconnected

no... Wifi port has ESP-CS PB12 ESP-MOSI PB15 ESP-MISO PB14 ESP-CLK PB13 There are all directly connected to the MPU SPI2 port io pins The sdcard on the screen is #define SD_SS_PIN PA4 #define SD_SCK_PIN PA5 #define SD_MISO_PIN PA6 #define SD_MOSI_PIN PA7 This is directly connected to the MPU SPI1 port io pins

Re: Upgrading marlin v1.0.0 to v.2.1.2.5 - Z offset to the Bed - 7 days ago

Marlin settings basics 101: Settings that can be changed via gcode or LCD are saved in EEPROM The EEPROM setting are independent of firmware settings. Updating firmware will not update the values stored in EEPROM (1)(2)(3) NOZZLE_TO_PROBE_OFFSET is one of these variables. (1) On the first time you update with new firmware, if the EEPROM version does not match or the saved checksum is invalid,

Re: esp32(esp3D) WIFI module wont talk to marlin (serial port config?) - 10 days ago

You do not define hardware uart pins in the pins file or the configuration files You don't need to define them at all, this is done for you as parts of the build environment, and yes they should be named like they are. -DPIN_SERIAL3_RX=PD_9 -DPIN_SERIAL3_TX=PD_8 yes you need #define SERIAL_PORT_2 3

Re: esp32(esp3D) WIFI module wont talk to marlin (serial port config?) - 10 days ago

The most common reason for serial ports not working is your trying to use buggy 4 year old code on the BTT github This old broken code sets the cpu clock frequency wrong and messes up most timing, especially baud rates (except for port -1 which actually ignores baudrates)

Re serial port You look at the pins diagram There is also a copy in Marlin/src/pins/stm32f4/pins_BTT_SKR_V2_0_common.h /** * ------- * GND | 9 | | 8 | 3.3V * (ESP-CS) PB12 | 10 | | 7 | PB15 (ESP-MOSI) * 3.3V | 11 | | 6 | PB14 (ESP-MISO) * (ESP-IO0) PB10 | 12 | | 5 | PB13 (ESP-CLK) * (ESP-IO4) PB11 | 13 |

Re: Melzi V2 Board question - 20 days ago

Communications with this board is two part a) the board has a FT232RL serial to USB chip. Your operating system needs drivers to see this and talk to it. Also due to ftdigate (google it) , this converter chip may be bricked (its old enough to have been caught by this) b) the MPU has to be running some code to respond to serial. This includes the baud rate Most common baudrate is 115200 or

Re: Marlin: Pin assignment for ESP32 - 24 days ago

esp32 does not have sufficient IO pins for most 3d printers, so an IO expander chip is used There are two different types of io expanders currently implemented One is via serial, pins >= 100 on this type of IO expander are on the expander. The other is via i2s when pinis with bit 8 is set ie >= 128 are on the expander. See Marlin/src/HAL/ESP32/fastio.h for more details.

Re: Mks gen L V2 Timeout error - 8 weeks ago

There should be no need to use the reset button. The CH340 DTR line is connected to avr reset, avrdude knows to assert this line to reset the controller to start upload. This can bee seen on the last page of the circuit diagram You either have a hardware fault or the boot loader has been damaged, Install stock atmega2560 boot loader, using a avrisp. see as one example on how to do this.
