Re: Marlin boards - 6 weeks ago

That's like asking, "Why can't I use a sledgehammer to do microelectronics?" You have to fit in with the already existing marlin systems Your code will display a few simple things, and that is it: no Marlin, no user interface, no supporting multiple display types, no supporting multiple hardware interfaces, no supporting a variety of touch controllers, no supporting different screen resolution

Re: Marlin boards - 6 weeks ago

re TFT_COLOR_UI, TFT_CLASSIC_UI, TFT_LVGL_UI These are the user interfaces available on the TFT screen. You need to pick one. (note TFT_LVGL_UI requires additional flash chip.) But no one has yet added SPI TFT support to DUE HAL. This is why you get "Sorry! TFT displays are not available for HAL/DUE" And FSMC_TFT is not an easy option, as not all the pins are broken out.

Default Configuration.h and Configuration_adv.h that come with Marlin are for a RAMPS. You literally needed to change nothing at all.

Re: Marlin boards - 6 weeks ago

I don't know why/how you keep breaking things, but here are some things you need to know about the mega2560 and serial (UART) It has 4 hardware UARTS [0-3] these are not mappable; they always use the same IO pins. You can use these IO pins for other things; you just loose UART access The pins are: UART0 -- TX0 = D01 RX0 = D00 (Connected to UART to USB chip on mega, also on AUX1 on RAMPS)

Re: Marlin boards - 7 weeks ago

Contradictory information: "Uploading to a Due, Windows sees it as a 3D printer." "Compiling and uploading to a Mega2560 V3, WIndows just sees it as a USB device." You cannot run DUE code on a mega2560 (or vice versa). You need to recompile for each processor. The log is showing that the board is not responding The Mega2560 V3 should be seen as a usb serial device. Depending on what it's u

The pin names are standard names and Marln knows to set those as input/output as required E.g., X stepper driver pins see Marlin/src/module/stepper/indirection.h // X Stepper #if HAS_X_AXIS #ifndef X_ENABLE_INIT_STATE #define X_ENABLE_INIT_STATE !X_ENABLE_ON #endif #ifndef X_ENABLE_INIT #define X_ENABLE_INIT() SET_OUTPUT(X_ENABLE_PIN) #define X_ENABLE_WRITE(STATE) WRITE(X_EN

Re: GENERAL QUESTION - 7 weeks ago

@sbkenn Level shifters have little to do with firmware. They simply translate voltages between devices. Marlin generally doesn't know or care whether a signal passes through a level shifter or not. The relationship is more like: Marlin ↓ HAL (SAM3X / Due) ↓ Pin definitions ↓ MCU GPIO pins ↓ Level shifters, drivers, sensors, etc. Eg Configuration.h you set MOTHERBOARD, this defines

Re: Help with masterprint firmware - 2 months ago

The firmware looks fine, but since I dont have acces to this board I cannot confirm it 100% Two possibilities come to mind 1) You're using a charge-only USB cable. 2) The USB port or controller is actually damaged Since you say you tried Linux, does the USB device show up under `lsusb`? If it was a new Linux, did you add your user to the dialout group? `sudo usermod -a -G dialout $USER` so

Thermistor type 5 is NTC device Ie it follows this graph So for a high temperature it has a low resistance. So your looking for a short. Unplug the bed thermistor at the motherboard, stick multimeter probes up the two plug pins so you can measure the wires and thermistor resistance. It should read 100K at 25℃

Re: GENERAL QUESTION - 3 months ago

The ramps 1.6 (like the older 1.4) sends 12v to the mega2560 vin pin via diode D1, the mega2560 board does the 5v generation So check for 12v on both sides of D1 (with gnd on a gnd pins), if it has 12v on both sides, its likely an issue on your mega2560. To test mega2560 board unplug the ramps from it and power it via 12v dc jack. as for the screen, what screen does it have? (pictures if your
