I have been at it for a month now and have gotten to the point where I may just tap out. Some one help! No point in going 8 bit when 32 bit is available and applicable.
Not to mention cheaper. When Marlin compiles in VScode it deletes the existing. I agree that the SKR v1. I believe the original question was how to update the board once Marlin is compiled. All that is necessary is to copy Firmware. The Firmware. You can also copy the files using usb once the SKR is configured to show as an attached drive.
As an aside, I love my SKR v1. I currently have one installed in my Ender-3 Pro. There is significant interaction between some settings. Making a bunch of changes at the same time makes trouble shooting much more difficult. In the end, for me at least, is the money. Cheap, quick or good, pick two. The ELF format is in use by several different operating systems. SKR V1. Where as pull-down resistor will connect the pins not used to the ground which is 0V and as such gives a LOW input.
BLTouch or other sensor probes normally need to have the switch they are connected to set to pullup. Now enable the relevant switch for a pull-up or pull-down by removing those forward slashes for the individual switches.
See below for example. Now if upon testing your end-switches and they are not triggering you may need to invert the signal, luckily this can be in firmware rather than fitting new switches.
Below is an example of an inverted logic for the probe or BLTouch not triggering when homing. Probes make life a little easier when it comes to bed levelling, however sometimes they take a bit of tweaking and trial and error to getting working well. All going well you can simply plug into the servo or probe inserts on the SKR V1.
Have a look at our SKR V1. Naturally Marlin needs to know where the probe is connected. However, it is still good practise to set it just encase there has been a mistake made with an update to Marlin. Now we need to set what type of probe we are using. If the sensor on the 3D printer is an inductive or a switch type sat on the nozzle then enable the fix mounted probe. So at this point Marlin knows there is a sensor, it knows what type and where it is plugged in.
Without Marlin knowing this, the point in height for where the nozzle will always be wrong. As it is the measurement for 22mm away to the left of the nozzle. So by telling Marlin where the nozzle is physically located Marlin adjusts that point of reference accordingly. Now the the height is correct.
So if you are using a 3D printed model supplied from say Thingiverse or a purchased holder. Ordinarily the distances needed to set are normally enclosed. The Z Height adjustment comes much later. So on the example below, my probe position that I designed is exactly 22mm to the left. It is not in front or behind the centre of the nozzle.
Now if the nozzle is to the left it is a negative number, if it was to the right you would leave off the minus. In Marlin if the probe is behind the nozzle it is a positive number, and if it was in front then it would be a negative. Marlin supplies a little example in this section. Moving along, I personally like to have multiple probes, this takes twice as long, but is more reliable. In essence with to probes one is fast and one is slow.
The measurement is then average but with more emphasis on the slow probe for the averaging. If this sounds good to you then enable Multiple Probing and set the value to 2. While not just specific to the SKR V1. Not only is this key for printing boundaries but also required for getting as much of the bed level as possible. For example if your printer was a Anet A8 it would be x Alternatively if say it was a Creality Ender 3 Pro it would be x Yes , you can get more bed levelling nearer to the edge even with the standard setup.
Now Marlin needs to know how high the printer can print too. In Marlin 2 there is a section for a software minimum end stop. Lets say the height for the Z-Axis is 0mm. It would stop at 0mm and not go any lower. However when bed levelling this causes an issue where the probe or nozzle can not be lowered enough. See below for an example. There are various options for the style of automatic bed levelling within Marlin.
Importantly for the most part when the printer is set to home the G28 command is giving. However it will forget any previous bed levelling probing. The next major step in setting up bed levelling within Marlin is the amount of grid lines per dimension is used. IspError: programmer. Save the changes to the file and restart the Cura software. Close Menu. Download the desired firmware BIN file to your computer. Rename the file to firmware. Copy the file to the SD card included with the board.
Power on the 3D Printer with the SD card loaded.
