Re: PCB Creality 4.2.2 (STM32F103RET6) and Marlin FW relations - 22 days ago
For no bootloader operation you have to edit the build environment settings eg board_build.offset = 0x7000 board_upload.offset_address = 0x08007000 Says the firmware should start at 0x08007000, but without a bootloader it will never start since code starts at 0x08000000 So change to board_build.offset = 0x0000 board_upload.offset_address = 0x08000000 But I recommend restoby Dust - Firmware - Marlin

Re: My display shows random lines and blocks - 26 days ago
This is what you get when the LCD hasn't been initialized. Causes could be firmware or hardware. One very common cause is the screen comes is two versions. One version has the cable keys facing up, the other down. You have to physically check that the lcd is getting 5v and gnd on the correct pins. If it is wrong rotate both cables 180 degrees at one end, yes this involves cable modificationsby Dust - General

You seem to be using Arduino IDE This is old and slow and only supports a small subset of boards I strongly suggest you install platformio under vscode (text editor) See If you continue to have issue I also advise you join the Marlin discord where you can get live help.by Dust - Firmware - Marlin

Re: Help compiling for ender 3 - 6 weeks ago
You really need to work out how to build firmware for yourself, so you can make any tweaks you want to.. I would strongly suggest you use the Marlin Discord server, doing this via this forum could take weeks.by Dust - Firmware - Marlin
Re: Marlin - Help with Macros M810 - 8 weeks ago
"Just to confirm: macros are loaded at startup, but they can be overwritten at any time from the serial terminal — for example, sending a command like M810"" clears that macro, or sending a new M810 command overwrites the previous one. Is that correct?" Yes they can be over written at any time using gcode M810-M819 No there is no way to lock them without coding and changing things.by Dust - Firmware - Marlin

Re: Marlin - Help with Macros M810 - 8 weeks ago
You enable STARTUP_COMMANDS and add the gcodes you want. Individual startup gcodes are separated with a \n multiple gcodes in a GCODE_MACROS are separated with a | Eg #define STARTUP_COMMANDS "M810 M300 S440 P50|M117 Tone played\nM811 M300 S660 P250|M117 second tone played" Will set M810 to "M300 S440 P50|M117 Tone played" and set M811 to "M300 S660 P250|M117 second tone played" on startupby Dust - Firmware - Marlin
Re: Which touchscreen displays are compatible with RAMPS 1.4? - 2 months ago
most touch screens are serial devices. Ie they they are in really small computers with screens connected via serial to your controller. EXP1/EXP2 is normally used for 128x64 pixel or 20x4 character lcd displays which many touch screens will emulate. Why you may ask? Because touch screens focus on looking pretty and ease of use but are limited in functionality. the stock 128x64 lcd has all possibby Dust - General

Re: old Marlin-Firmware - How to update? - 2 months ago
yes* Most new fun features require a 32bit controller, a 10 year old 16mhz 8 bit controller is just not powerful enough. *You can upgrade, and enable a few new thing, but not all the new thingsby Dust - Firmware - Marlin
Re: old Marlin-Firmware - How to update? - 2 months ago
M503 will display some settings but the rest you will have to work out But looking at your previous posts you added unsupported i2c io expander, that will be fun to port Also it is recommended up upgrade your motherboard to a 32 bit controllersby Dust - Firmware - Marlin
Re: Is it possible to increase printing speed in a 3D printer based on Marlin? - 2 months ago
I've been talking with the main developer for FT-MOTION input shaping in Marlin and he recommends "a board with an FPU, like SKR3 or Octopus Pro with the H7 MCU" You need good input shaping for higher speed printing. But here is an example he posted of a 14:12 min benchy on Marlin with his latest FT-MOTION code, and unlike more extreme speed benchy it still looks like a benchy! . (his hotendby Dust - Reprappers

Re: Rostock Delta goes back to 0-0-0 after every move or extrusion - happens also during print via USB or SD card - 3 months ago
Darn... I should have seen that normally on a Delta it defined like this, #define X_BED_SIZE ((PRINTABLE_RADIUS) * 2) #define Y_BED_SIZE ((PRINTABLE_RADIUS) * 2) #define X_MIN_POS -(PRINTABLE_RADIUS) #define Y_MIN_POS -(PRINTABLE_RADIUS) #define X_MAX_POS PRINTABLE_RADIUS #define Y_MAX_POS PRINTABLE_RADIUS Note provided configs are also missing #define BED_CENTER_AT_0_0by Dust - Firmware - Marlin

I'm not sure if its related to your delay or not but M410 can be handled by EMERGENCY_PARSER, ie it jumps to the head of the queue as soon as its is seen in the serial buffer. code is in Marlin/src/feature/e_parser.h / Marlin/src/feature/e_parser.cppby Dust - Firmware - Marlin
Re: ANET A6 Marlin 2.0 - 3 months ago
The Anet 1.0 board is just a nightmare Tiny amount of flash 128K Most do not have a bootloader so you need to install one. Even if you have one it is recommended you install the smaller optiboot, There are 3 build options (sanguino1284p, sanguino1284p_optimized, melzi_optiboot) you want the last one. It gives you most firmware space, but you must install the bootloader first Even attachiby Dust - Firmware - Marlin

No! Many klipper users are under the delusion that Marlin is slower. This is not true, You do need faster controller CPU. In klipper its a raspberry pi doing the heavy work, in Marlin you need a 32 bit boardby Dust - Reprappers
Re: How to configure real position of endstop - 3 months ago
then its a poorly built machine and effectily that part of the bed does not exist, as the machine cannot put the nozzle over it Then the home position is 0, and you measure the bed size from that lineby Dust - Reprappers
Re: How to configure real position of endstop - 3 months ago
It depends on your firmware In Marlin its these settings #define X_BED_SIZE 200 #define Y_BED_SIZE 200 #define X_MIN_POS 0 #define Y_MIN_POS 0 #define X_MAX_POS X_BED_SIZE #define Y_MAX_POS Y_BED_SIZE If you home to Y min then Y_MIN_POS is the postion of that endstop, if you home to Y max then Y_MAX_POS is the position of that endstop often min values are less than 0by Dust - Reprappers
Re: Third Neopixel LED strip - 3 months ago
These neopixels are actually a PITA in the current implementation (ie bit banged), they have strict timing requirement that is in conficts with the primary function of the controller, ie to produce percision step and direction pulses for a number of stepper drivers... More neopixel strips compounds the conflicts.by Dust - Firmware - Marlin
