Re: can marlin share an SD card via WIFI on skr-2 board - 1 year ago

interesting, I'm really not familiar with how open source development works behind the scenes. So someone has to write the feature first, then it can get added?

any plans for marlin to do the same in the future?

Re: can marlin share an SD card via WIFI on skr-2 board - 1 year ago

lemmy see if I understand this right: to do what I want, the MPU would have to be connected to the same SPI as the screen (spi1) ? and since they are direct connections to physical pins, that cant be changed, right? There must be a reason those pins were included with the WIFI port, what is it? How is that meant to be used? Thanks again...you really seem to do a lot of heavy lifting in thi

can marlin share an SD card via WIFI on skr-2 board - 1 year ago

I have an skr2 with an esp32u (BTT) add on wifi module. Got it connected as a simple serial setup, thats fine. But what I would really like to be able to do is send files to the esp32 and have it write them to a shared SD card. From studying the pinouts, it really seems like I should be able to setup and spi connection to my sd card. Ideally that would be the one in my LCD, but I could live w

Re: esp32(esp3D) WIFI module wont talk to marlin (serial port config?) - 1 year ago

update: once I knew it was serial 3 I needed(thank you), that limited options a lot. and your comment out the BTT firmware & speeds had me look into the firmware I compiled for the esp32. Sure enough the platform IO ini had the port set to 115200, while marlin was set to 250000. 115200 all the way around worked! oddly enough, its the ONLY baud rate that worked. I tried juicing it up t

QuoteDust 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 well I have already tried that, along with every other port number. What about th

Re: esp32(esp3D) WIFI module wont talk to marlin (serial port config?) - 1 year ago

QuoteDust Re serial port And note that PD8 can be USART3_TX and PD9 can be USART3_RX, IE this is UART 3 "could I reverse 0 & 2" yes. "marlin embedded" Marlin firmware itself is running on a chip that has wifi inbuilt, such as the esp32 "SPI connection, why aren't we using that" because Marlin only supports gcode over UARTS (port numbers >= 0) , USB CDC (port -1 ) and Ethernet (-2 is

esp32(esp3D) WIFI module wont talk to marlin (serial port config?) - 1 year ago

I'm working with a BTT SKR-2 motherboard and an esp32u add on board. It is the BTT variety of the add on, but the original firmware (if there was any?) is long gone. I've manage to flash esp3d (3.0) to the wifi module. It created an access point that allowed me to get in and setup the webUI and its connection to my home network. The whole esp3D web UI seems to be be functional, but it would

marlin delta printer acting like it had a stroke - 6 years ago

fairly recently upgraded to marlin 2.0(bf) on my scratch built delta printer, had some problems with calibration but eventually got it running and was making some decent prints. I was looking forward to using some of the new features like linear advance, but then the printer started acting in a manor that I can only describe as "goofy". It started with skipping steps & jamming my extruder, so
