If your printer knows when it has run out of filament, it can abort the job, or it can pause while you load new filament. To do this the printer needs to have a filament-out sensor attached. These come in two types: simple switches that detect the presence of filament, or sensors that detect the motion of the filament.
RepRapFirmware supports a variety of different filament presence and motion sensors using the M Gcode :. See the M Gcode for full configuration information. The first step is to connect the switch to an unused endstop connector on the Duet 2. To make the firmware run a script when the filament runs out, use M to associate the endstop you chose with a "trigger".
Trigger 0 is an emergency stop probably not what you wanttrigger 1 pauses the print running pause. Finally, the trigger only happens when the endstop changes state. If you try to start a print with the filament out, the trigger won't happen. So add M to the start of your prints to check the filament state and run the trigger if there's no filament.

Sign up.Sir, I want to add optical sensor to my ramps 1.
Thanks Reply Quote. I wired my Filament run-out sensor to X-Max and changed in pins. As the pin they suggested did not work for me. I made the Filament run out sensor using a lighted end stop circuit board.
You could make it with just a switch, I wanted a Lighted verification that filament was enabled. I designed and 3D Printed a small case that does not require nuts and bolts. Reply Quote.

Runout Thomas www. Quote Replace What does the printer dowhen this pin gets high? I would like to have Repetier-Host go into pause mode Quote Replace so, filament-runout is a standard feature already, but now connected to a endstop for choice? Ok, but what does happen when it is triggered? The normally closed switch I am using is high until filament is present then goes to ground. The circuit shown is just the way I decided to wire the Filament run out sensor as I wanted a light when filament present.
I have not! This is not really a filament pause: as all data is stored as to where to begin printing when filament is restored. After some time the Heaters are turned off for safety reasons when left unattended.
You have to remove the broken filament remaining in the extruder before you can replace the filament, then Pressing Click encoder button to continue.GitHub is home to over 40 million developers working together to host and review code, manage projects, and build software together.

But the Endstop I have, has 3 pins and the E0-Stop has only two? And Marlin says to me, that I have to put the sensor in the servo 3 port.
Some of the filament sensors have only 2 wires and some 3. Even most of the 3 wire versions work with 2 wires. So either you find out which 2 pins are needed and customize the wiring. Alternatively if you want to use 3 wires you could install the filament sensor to PT-DET port and customize the pin config file. Refer to the wiring diagram of the specified filament sensor you have and the control board pins schematics.
Ok I've changed the pin to PC12, checked if the sensor is aligned with the pins but it seems not to work. It might be that the sensor needs its state inverted. What sensor model do you have? I use the ender 3 z-sensor. But when he is just inverted shouldn't he activate the M GCode when I press it. If you read the comments on the filament sensor feature in the configuration.
So this expects that the microswitch circuit should be open when filament is present and when filament is removed the switch would close the circuit connecting the sensor pin to GND. I've just meen changing the extruder to DD and don't have the filament sensor installed currently but I can check it later. However, previously it's been working with the above logic.
But start with the M to figure out the state of the switches. No, I didn't forget to uncomment that, M says that the Sensor is triggered when filament is in it that should also matching to my settings.SKR V1. The installation of this board into an existing setup is very easy. Quite often it is a case of pushing the metal pins down, pulling out the cable and swapping the wires around. This depends on how the connections were wired on the previous 3D printer board.
Now on this occasion we are going to be setting up the SKR V1. However I will break it down to make it easy to follow along. It requires a light bit of soldering of two contacts as circled above and is a quick job. Time your time there is no rush. Now insert the stepper drivers into their positions ensuring they are orientated with the potentiometer facing leftwards towards where the power, heated bed and extruders will be wired into.
TMC stepper drivers run particularly hot, so we need to keep them cool. Heatsinks placed on the stepper drivers help a little with this.
Although active fan cooling is fundamental in running them cool. Fix your heatsinks as central as possible to the gold section on top of the TMC ensuring that the heatsink is not contacting with any of the soldered pins on the driver itself. Connecting your LCD screen is another simple step on the hardware installation.
If when powering up the SKR V1. A very simple installation, one end of the cable can only fit into the TFT one way. Opposing end sits in line order with reset button The one loose connector to the far right or from the angle of the picture above the far left.
Just encase the cable changes in the future or you are using a custom cable then the pin layout is as follows. On the SKR Working left from right.

Left being nearest to your power supply connection to the SKR V1. Altered from schematic, to aid installation. Left being nearest to the SD memory card slot connection. Now when it comes to wiring in your BLTouch the wiring is slightly changed when it comes too connecting with the board.
It is not just in a straight line coming from the probe. It is a little jumbled up. Nevertheless its an easy process, just follow the colour of your cables from your BLTouch and switch them around when you plug them into the SKR V1. You may need to change the pins on the end of your cable, but its relatively easy if not simply monotonous at times.
I have listed the order below from left to right. Left being nearest to your power supply connection on the board. If so please give a like or share on social media so that others may find the SKR V1. It is worth mentioning that you could still go further with setting up the SKR V1. To accompany the SKR V1.I just picked up the Bigtreetech SKR v1. I'm still having trouble using the Octoprint firmware updater plugin, but it appears that there's active development to get it working on these boards a new build was uploaded 11 hours before this posting, so I expect the kinks to be sorted out soon.
As such, I had to manually copy the card back and forth a few times, after forgetting to invert one of my steppers yikes. Physical Installation Stepper Drivers It's always a bit of a pain to check the voltage on the stepper drivers and you can manually assign voltages in Marlin 2. Setting the voltage took about 5 minutes. I just followed the image below:.
Wires You can use all of the same wires if you're coming from a stock controller, except for your fan out. This board uses a JST connector for the fan check your polarity! Exp1 and Exp2 positions are flipped and the wires plug in reverse orientation. Mounting the board The board has the same height as the stock board, but it's just a little bit shorter on the length side. I mounted it using the same holes closes to the power supply so that my power supply wire lengths could stay the same and just drilled in one more hole to add a third point of contact.
Ok, I'm lazy and should've drilled a fourth, but whatever. This thing is quiet and fast. The loudest part on the printer is the power supply fan a massive mm case fan mounted on the inside. Movement of the printer head is virtually silent.
These are far superior to the 2. I've updated the link to the new v3 chips :. The branch of Marlin 2. The bug was only recently identified and fixed in the bugfix branch, so I recommend starting with the Marlin 2.
Thanks for the tips! I've got an SKR 1.

I don't think Bigtreetech has made any updates to their Marlin code so I'll go with the latest bugfix too. Would you care to share your configuration file? Today I've been going through the default configuration. I think I've got it where it needs to be now.RAMPS 1.
