Thank you for these thorough videos.
I would literally have no idea what to do without you.
You're welcome.
First of all, very informative video gallery... I've made a full fledge printer watching these videos...
I only have two observations.
In each video, you are always talking about how to download and setup Marlin. Shouldn't you be using an existing installation? trying top to explain how to modify an existing setup? I mean, how practical is it that someone buys a brand new SKR pro and the first thing they want to hook up are the fans!? Myself, I have now set up X, X2, Y, Z, motors, the end stops bed size, Temperatures, Heat bed, and also done the motor, extruder and heater calibrations. I've even done a test build with the fans powered directly from the supply. Now I'm looking to automate the fans that brought me to this video of yours.
And you do this in every video! I'm at 5:49 in your video and you are still installing Marlin. So, practically, I skip the first 5 minutes of your videos without watching...
Secondly, I always have to play them at 1.5x or 2x the speed... You don't have to speak like you are giving a one-time only press briefing. Its youtube. It has subtitles ad people can always pause and rewind if they don't understand anything. Even after watching it at this pace, we do have to watch it multiple times because there is too much information and we miss something almost every time.
The reason I speak about the same thing in every video is not everyone watches every video.
Also in order to have a mostly clean CC I need to talk slow or boot screen turns into blue screen.
@@EdwardBraiman Hi ed.
First of all, I want to apologize for the above comment. I was out of my mind, angry at myself for bricking my brand new TFT24 with a stupid mistake (Plugged in BLTouch, thinking that if 5V is in the same place, everything else would be too).
Your videos are wonderful! In fact, I selected BTT SKR Pro 1.2 for our BigFDM (Inspired from github.com/fab-machines/BigFDM) after watching your videos. Last night, we did the first successful build. Here are the features we are going to implement:
350x300x280 build size,
300x300 hot surface
2nd Extruder on X2
BLTouch
ESP01
Flexible build plate
Can you do one video on the 2nd Extruder (E1) on X2? We have already configured E0 and E1. I can heat it up and extrude too. But the motor doesn't move yet. We would like to do, Multicolor builds, Copy builds using 2 extruders, multiple parts at the same time using the two extruders.
my 3 fans are ON all the time what is that means ? blown mosfet ? can i replace it ?
Depends. There's a Discord link in description, so you can ask me or someone else in general chat how to understand issue better.
nice tutorials definitely will come in handy couse planing to build printer wit either skr pro or gtr which is in my opinion better that duet as it has inter changeable motor drivers... non the less have question on power ports.... as i understand every power input line is electrically separated, so is it possible to run steppers and their drivers on 24vdc while board and fans powered by separated 12vdc power supply unit???? Idea is to run steppers and hot end on 24vdc , fans on 12vdc (as more options are available), and heatbed on 220vac.
You maybe able to do this, but I recommend only one power supply. I prefer 12v.
Excellent Tutoring Edward 👍🏼, following you step by step for the SKR Pro V1.1, soon should my GTR V1.0 arrive, would be great if you could help setting up 4 independent Z steppers
Why four?
@@EdwardBraiman preparing to build a Voron 2.2 but trying to have it working with marlin 2.0 instead of klipper
You may need to split stepper output.
@@EdwardBraiman check the Voron build, it uses 4 independent Z steppers and the gantry auto leveled by them being synced
I'll need to research.
1. Write firmware.bin file to the SD card.
2. Put in SD card in to the SKR PRO
3. Press reset button on the board.
4. Wait until led stop flashing.
Thats all, your firmware updated.
Switching power mode and plug in USB cable absolutely not affects firmware update. ;)
What's occuring is on the root of the micro SD card when power is applied it points to the firmware.bin. after it's loaded it renames file to FIRMWARE.cur. I waterdown the tutorials.
Nobody will be harmed by 12V!
While I understand your perspective, remember a AA battery can harm a human. Safety first.
Hi, I'm trying to get my SKR Pro V1.2 to talk to my PC and Octoprint via usb without much success. I have made the changes you have made in this video any ideas where I am going wrong?
Thanks
What's the jumper set to on board for USB or is it on direct power? Does the COM port appear in Device Manager?
Hello and thanks for your tutorials ! I follow this one but it don't works on my SKR PRO V1.1. fan 0 works fine, but nothing happen when i'm trying to launch fan 1 or fan 2. Do you have an idea of the issue ? Thanks
Normally when I have an issue, it's a bad fan or a wire not fully connected. Try testing with a multimeter. Let me know how it works out.
Hi, I just test with a multimeter to be sure. After few test, I found something strange, Fan0 can be set manually, Fan1 start automatically at 100% when I start to move any motor and stop after 3minutes. I'm searching if there is something similar for Fan2.
Is the Marlin firmware preconfigure for configuration.h or configuration_adv.h?
Hello,
as you advised me I searched more and effectively there is a preconfiguration in configuration_adv.h for the fans.
Here are the 2 sections :
/**
* Controller Fan
* To cool down the stepper drivers and MOSFETs.
*
* The fan will turn on automatically whenever any stepper is enabled
* and turn off after a set period after all steppers are turned off.
*/
#define USE_CONTROLLER_FAN
#if ENABLED(USE_CONTROLLER_FAN)
#define CONTROLLER_FAN_PIN PE6 // Set a custom pin for the controller fan
#define CONTROLLERFAN_SECS 60 // Duration in seconds for the fan to run after all motors are disabled
#define CONTROLLERFAN_SPEED 255 // 255 == full speed
//#define CONTROLLERFAN_SPEED_Z_ONLY 127 // Reduce noise on machines that keep Z enabled
#endif
**************************************************************************************************************************************
/**
* Extruder cooling fans
*
* Extruder auto fans automatically turn on when their extruders'
* temperatures go above EXTRUDER_AUTO_FAN_TEMPERATURE.
*
* Your board's pins file specifies the recommended pins. Override those here
* or set to -1 to disable completely.
*
* Multiple extruders can be assigned to the same pin in which case
* the fan will turn on when any selected extruder is above the threshold.
*/
#define E0_AUTO_FAN_PIN PE5
#define E1_AUTO_FAN_PIN -1
#define E2_AUTO_FAN_PIN -1
#define E3_AUTO_FAN_PIN -1
#define E4_AUTO_FAN_PIN -1
#define E5_AUTO_FAN_PIN -1
#define CHAMBER_AUTO_FAN_PIN -1
#define EXTRUDER_AUTO_FAN_TEMPERATURE 50
#define EXTRUDER_AUTO_FAN_SPEED 255 // 255 == full speed
#define CHAMBER_AUTO_FAN_TEMPERATURE 30
#define CHAMBER_AUTO_FAN_SPEED 255
**************************************************************************************************************************************
So I found a good solution, now with that settings my configuration is :
Fan0 for the Nozzle (set manually or by the slicer)
Fan1 for the extruder Heatsink (automatically start at 50° and stop below)
Fan2 for the Drivers (automatically start when a driver is started and stop after 60sec after the last driver has worked)
Thank's for your advices
@@BrianCYVOCT Huge thanks! The pins file for both Pro 1.1 and 1.2 is now in a PRO_common ini and the fan code reads very different now.
I see you have 12v fans hooked up.
What is the voltage output of the skr pro fan pins? Can you use 24v fans?
The fans usually are the same as the PSU voltage.
I'm a bit puzzled. while understandinbg your video, i ask myself whats the recommendet practice for connecting the hot end cooler on the SKR PRO.
To a PWM controlled pin like here, or directly to the power supply so that the fan runs always when the printer is on?
Also it seems i need 24V fans when powering the board with 24V - there is no step down converter on the board for 12V fans?
Well they make 24v fans and I would advise you to check reprap wiki or forums for there recommendations. All my videos are based on 12v operation for the tutorials.
@@EdwardBraiman thanks :)
Thanks for your work. I have SKR PRO v.1.2 and SKR TFT35 v.2. I have a few questions. 1. Can two fans be controlled from the screen menu (F0, F1)? 2. My Neopixel does not turn on from the screen menu. In the firmware, the Neopixel is connected to the PC9 pin. In SKR 1.4 turbo everything worked. Thanks.
For TFT display they developed a configuration file that you can add fans to with firmware upgrade.
As for the neopixel you might be able to add a gcode now via txt.
@@EdwardBraiman At the moment this feature is not implemented in the SKR pro v1.2 + SKR TFT35 bundle? I can only activate this feature in the starter Gcode in Cura. Did I understand correctly? (sorry for my English)
I think the feature maybe in TFT display, but I'd need to check.
Bonsoir serait il possible de nous montrer la configuration d'un bl touch sur la skr pro avec le marlin 2.0 merci
bonjour, ma nouvelle imprimante de démonstration arrive demain, donc je vais les démarrer bientôt, si les problèmes de firmware 2.0.x Marlin avec BLT ont été résolus.
why dont you use de marlin extension in visual studio to upload firmware to controller board.?
For SKR pro v1.1 it does not work.
Do you need to set the number of controllable fans in Marlin or not?
Yes.
@@EdwardBraiman i have an issue with an SKR PRO and a BTT TFT70. When I turn on the first fan on the screen, the first fan turns on, but when I turn on ghe second fan on the screen the first fan turns on. And the third fan doesn't work at all. Do you know what could be the issue?
More than one fan needs to be configured in TFT display configuration file.
I'll show in livestream fix at 6 PM EST today.
It's at the tail end of live stream the answer.
Hi Edward, i want to cool my printed part with two Fans.
How can i define that when Fan0 is on that Fan1 is also on and Fan1 goes every time the same Fan Speed as Fan0?
I try the following.
#define FAN_PIN PC8 & PE5
#define FAN_PIN PC8 and PE5
#define FAN_PIN PC8 + PE5
but nothing works. :-(
I'm already frustrated because I've been trying to find the solution for half a year
Try testing each fan command with gcode using p0, P1 and P2 in Pronterface and let me know the results.
@@EdwardBraiman Nothing happens except that the Fan3 which I don't use would run at P2.
But I want to control the outputs PC8 & PE5 synchronously with P0 alone
@@EdwardBraiman did you have any idear? :-/
can i use different voltage PSU for steppers only ?
like 24v for steppers and 12v for everything else
It's possible, but for safety and complexity I wouldn't recommend it.
Buenas,
cuanto me cobrarias para programarme un Firmware?en la placa Bigtreetech SKR PRO V1.1?
desafortunadamente estoy un poco ocupado con lo que está sucediendo hoy en Nueva York. Tenga en cuenta que si mira mis tutoriales, todas las respuestas están cubiertas entre mis listas de reproducción. Cuídate.
@@EdwardBraiman OK muchísimas gracias,y si es lamentablemente,está pasando aquí también,que sigas bien.
Could you share your config and config h files for the 1.4 I can't get my probe to work
Which probe are you referring?
@@EdwardBraiman the inductieve sensor from prusa I have a no and a nc
@@Foldingblade you need to use sensor in tutorial.
@@EdwardBraiman I did but I it doesn't change in prontor face and the machine doesn't react to the input if I short the pins it does stop
Does your part number match what's in the tutorial?
I have to play the vedio in 2x speed to feel is normal speed
Thank you.
