Re: SKR 1.4 Turbo and RRF troubles - 4 days ago

Blue led is on tx line, it glows when the signal is low. But only if the board has power The lpc176x pins for serial 3 Serial3 TX RX FUNCNUM Default P0_00 P0_01 2 LPC_PINCFG_UART3_P0_25 P0_25 P0_26 3 LPC_PINCFG_UART3_P4_28 P4_28 P4_29 3 The wifi port on the skr 1.4 uses P4_28 and P4_29 so you need to enable function 3 In marlin you set LPC_PINCFG_UART

Also make sure your using a data usb cable. Charging usb cables do not have the required data io lines

Re: No Connection possible - 8 days ago

Those driver are for FT232RQ chips not ch340 chips.. fairly sure your board has the later. Look at your board, see the chip behind the usb port, what does it say written on the top of it?

Re: No Connection possible - 8 days ago

COM ports are windows/dos operating system ports SERIAL_PORT is Marlin firmware controller serial port One has nothing to do with the other ------------------ usb cable ------------------------ | windows Com 1 |--------------------| Marlin SERIAL_PORT 0 | ------------------ ------------------------

Re: No Connection possible - 8 days ago

Its a mega2560 board you need to enable #define SERIAL_PORT 0 And #define BAUDRATE 115200 UART 0 is connected to a usb to serial chip. Normally a ch340 chip. If you using windows you need to install drivers for the OS to see port

Re: Full Graphic Smart Controller - Blank Screen - 10 days ago

Did you use platformio? as arduino ide you need to manually replace lib U8glib/ U8glib-HAL with latest version of U8glib-HAL platformio does this for you

Re: Full Graphic Smart Controller - Blank Screen - 10 days ago

Provided configs work fine on my identical hardware Best guess you didn't replace default configs with these configs. As default is also a ramps but without a screen.

Re: Hotend not heating - 12V but 0 amps - 11 days ago

resistance of 5.7 ohms seems a bit high. at 12v that is 25watts which is rather low for a hotend heater (40watts is normal, 3.6ohms) "when commanding the hotend to heat, I can read 12V at the hotend connector" The hotend has the gnd switched, there is always 12v on the connector, one pin always has 12v, the other pin is 12v (via the hotend heater) or gnd depending on if the mosfet is on or of

This is why GD32 chips are not well supported.. The required subsystems are just not there maple is a kludge, it doesnt really support gd32 very well at all..

Look at Marlin/src/pins/pins.h In the comment for each board is a list of valid build environments for the board.

Re: Stepper motors not working - 24 days ago

You install the number you want for the micro stepping you want, but 99.9% of people forget to install any These are the Jumpers for a A4988 (Jumper off = LOW) But your steps/mm is rather high for a old 8 bit controller. 3 factors are involved in moving. Steps/mm (and microstepping) Feedrate Stepper driver current. (adjusted via the variable resistors on the A4988's, set to match your step

Re: USB connection problems with 3D Printer - 24 days ago

Why on earth are you not using bugfix 2.1.x You need correct Motherboard and to define the correct SERIAL_PORT (which is different for every motherboard)

Re: Stepper motors not working - 24 days ago

Install 3 micro stepping jumpers under each stepper driver!

Re: Remapping Pins for Non-printer - 24 days ago

you don't need to remap any pins. (unless your trying to use a pin marlin has already allocated) remapping is for pins that have a function in marlin. your using direct pin control "M42 P32 S0" P32 is the pin your settings (Arduino pin name D32) Use D4 or D5 on the Servo plug, just change M42 P32 S0 to M42 P4 S0 etc. The main catch is you cannot use locked pins (pins controlled by mar

The 2B, 2A, 1A 1B four pin ports are the output of the stepper drivers. This has nothing to do with board pins. The board pins are well documented Top left

Re: ViKi 2 LCD on Ramps 1.4 - 29 days ago

The page has a link to "Get Support Files here" that no longer works. But waybackmachine does have that page and shows but those links are also gone By using some tricks I was able to get partial wiring PDF's but they are truncated to 1MB, had to repair them to see anything. But the important ramps stuff is of course missing!

Re: ViKi 2 LCD on Ramps 1.4 - 29 days ago

U8glib and U8glib-HAL provide the same API interface, you only install the latter I would strongly suggest you use platformio under vscode, its 100 times faster to complie than Arduino IDE, it also installs the correct library automatically see If you look at the Marlin/src/pins/ramps/pins_RAMPS.h file it shows what ramps pins are used for this display #define DOGLCD_CS

Re: Problem with output D10 - 30 days ago

Also the mosfet switches gnd. If there is another path to gnd it will stay on I have seen this many time where the hotend heater cartage is not insulated so the heater block is now at 12v all the time, Current doesn't flow due to not having a gnd path. Then the thermistor is screwed to the heater block, if you break the insulation on the leg it forms a gnd connection. Now the hotend is alway

Re: Wrong Axis is moving - 4 weeks ago

You would have to edit the boards pins file to have this fault, or perhaps setting the wrong MOTHERBOARD Or plug the steppers in wrong location.

Don't use Arduino IDE Use vscode with platformio. It's 100 x faster and it get all the required libraries you need for you. Also dont use OneDrive, it messes with builds

Re: LCD hotplugging - 6 weeks ago

anything that is hot plugged has to be designed that way Hot plug devices are designed with special connectors wher the GND pin is guaranteed to be connected first for eg take a look at sata power cable See the different length pins? the gnds are longer. Next the power supply of the controller needs to have sufficient current reserves not to brown out crashing the controller. Then the sof
