Ender 3 thermal runaway protection - 3 years ago

Hey guys, so I recently updated my ender 3 with the stock board v 4.2.2 and everything has been working great. Recently I had a thermal run away and the printer did stop and gave me a reset warning although there was no audio cue/buzzer did not go off. Is there a way to enable the buzzer in the code, if so could anyone please tell me how to enable it? Thanks

CR 10S Pro Heatbed SSR Fried - 3 years ago

Hey everyone, So I have a cr10s pro whose heat bed wasn't heating up but when I opened up the bottom to check the wires, I found that the entire ssr had been fried and the terminals were melted. Does anyone know how much current the bed actually needs for it to heat up and what alternative DC SSRs can be put in place here. If not does anyone know where I can purchase the stock DC SSR. Thank

Re: Y-axis Stepper Motor not working on Creality v4.2.2 board - 3 years ago

Thanks a lot @Dust. I think I will try to replace that driver from a different board but is there a way for me to verify that it is the stepper driver and not any other component in the chain to control that specific motor.

Y-axis Stepper Motor not working on Creality v4.2.2 board - 3 years ago

Hello, I bought a new Ender 3 which came with a stock creality v4.2.2 board, it worked great for the first 3 months. Now the Y-axis stepper driver just stopped functioning but the printer continues to print in a straight line along the X-axis. I have tried to use a different stepper motor in that port and tried that motor on a different port, to confirm that it was the stepper driver which is a

Re: Hot End not heating - 3 years ago

Even I assumed the same because the LED for the mosfet was flickering and would light up sometimes. So I replaced both the entire wire+thermistor and wire+heater cartridge for the hot end. I faced the exact same issue, when I tested it without plugging in the heater cartridge, the LED would flicker but the moment I plugged in the heater cartridge, the LED would go dead.

Hot End not heating - 3 years ago

Hello everyone, I have an AIO II v3.2 running a createbot max 3D printer. The printer was working great with a 24V 50W hot end. The hot end suddenly stopped heating a few days ago, only the green led next to the mosfet flickers for a while and then switches off. I tried flashing the firmware on it and instead of testing it with the hot end again, I tried it with the hot bed and hot bed thermist

300x300mm PCB heatbed - 3 years ago

Hello everyone, So I am trying to build or design a 300x300mm PCB heat bed using KiCad, I wanted to know if there are any reference designs or if someone has already done it for this size. I know that there is already a post on a similar topic for a large heat bed, but since it was posted years ago I wanted to know if anyone had any new ideas and maybe a fresh perspective on it. Any help is m

Re: Faster SD card write on marlin over wifi - 3 years ago

Thanks a lot @Dust. The second option would still require a lot of firmware changes right ? And I actually tried to change the baud rate to a higher value(picked the highest common baud rate in the firmware for both of the devices), a lot of things started malfunctioning and for a slightly lower baud rate, only the file manager stopped working on the webUI.

Faster SD card write on marlin over wifi - 3 years ago

Hello everyone, I was trying to connect an esp8266-01 board to an AIO II, v3.2. I got the wifi connection up and running, with esp3d i have the whole setup working now. I was just wondering how I could get the SD upload over wifi to be faster. 1.Does anyone know what the speed of the transfer is currently with a similar setup? 2.Does anyone know what the actual bottleneck is in this chain?

Re: Fysetc AIO II V3.2 wifi addition - 3 years ago

Thanks a lot @Dust. I also had a look at those schematics and the fysetc esp8266 my boss gave me wasn't working, (I couldn't get the Com port to show up). I did end up using a esp8266-01 board that I had and got it up and running. Although I did have to make the following changes- 1. The port I used was port 3, i.e. SERIAL_PORT_2 3. 2. The connection diagram was a little different, since my esp

Fysetc AIO II V3.2 wifi addition - 3 years ago

Hey everyone I was just wondering if anyone has or knows how to add wifi capabilities to the All In One 2 v3.2 control board. I have an esp8266 wifi module and an esp8266 from fysetc which comes with a chip to upload the firmware onto it. I Know that the Rx,Tx pins and the power pins need to be hooked up for the wifi module to work with ESP3D after flashing it on an ESP8266. Any help is much app

Re: Custom feature in Marlin - 4 years ago

Hello, Yes any information from some one who has already modified or has written the code would help. I would mainly like to know where the functions are written so that I could add my own into marlin. Shakthi

Re: Custom feature in Marlin - 4 years ago

Yes, I know I need to alter the code itself, and add new features as they are called my marlin but I do not know where to add my code, as in the file to add them in. I do not want to change the G or M codes themselves but want to add functionality that the machine would enact on their own. It should be a background task that is on from the moment the machine is switched on. Shakthi

Re: Custom feature in Marlin - 4 years ago

I understand how the M42 Gcode works. I want to write the code in the firmware itself so that it works without the host having to intervene to start and stop these devices. The thermistor assigned for the function should be reading the values based on which the pins get triggered ON/OFF based on the temperature reading. Thanks Shakthi

Custom feature in Marlin - 4 years ago

Hello everyone, I'm new to this(so please bear with me). I am trying to add my own features to Marlin and would like to know how and where I can add the following features. These features are for a Laser cutter I'm trying to build with the marlin firmware on an mks gen v1.4 board. The software upgrades will be mainly for automatically controlling the cooling system. 1. The first feature is to s
