skr 1.3 lcd displays manufacturer

In this video, I am showing you how to connect Bigtreetech TFT35 touch displays to your SKR 1.3 or 1.4 mainboard, why it has two different modes to use it and what to configure in Marlin 2.0 for it.

The second mode is the "Marlin" or 12864 simulation mode, which will show the original printer menu from the Marlin firmware running on the SKR mainboard.

So from the mainboard documentation, I know that the reset pin for the SKR 1.3 is the most right pin, so I will orient my cable connectors accordingly and plug them in with the reset pin on the most right pin and the other four go left to it.

Now, I am building and uploading this new firmware for the SKR mainboard with Auto Build Marlin and if you"ve missed my full guide how to do this, I"ve linked that particular video up here for you.

I have an Ender 3 Pro with an Skr1.3 and TMC2209s fitted, which is almost silent, so I decided to go this route on the E5+. I did not, however, want to replace the stock screen. I only really need the screen for being able to stop a print, or to move the axis – I print from Octoprint so have no need of a BTT TFT3.5 V3 screen etc (although I DO have one on the Ender 3)

Remove the board, and mount the adapter plate you printed earlier, then attach the SKR1.3 to the mounting plate. (You may at this point find it easier to connect the blue USB cable and sdcard extender before mounting as space is tight!) Note, when mounting the end-stop plugs in the SKR you will need to carefully cut off one of the lugs so it can fit. Looking at the diagram above, they connect to the two rightmost pins in the relevant sockets.

#define MachineEnder5Plus#define BedDC#define ABL_BLTOUCH#define ABL_BI#define MelziHostOnly // Enable this to turn off local SD support and instead prioritize options for Octoprint or USB#define SKR13 // 32 bit board - assumes 2208 drivers#define SKR_2209

#define DualZ // Uses 5th driver on CRX or SKR boards as Z2#define MeshStd#elif ANY(MachineCR10Orig, SKR13, SKR14, SKR14Turbo) && DISABLED(SKR13_ReverseSteppers)

Cycle the power, and you should now have a working screen, with Marlin 2.0 on your SKR, running 2209s in UART mode (No need to set VREFS) and enjoy the silence!

Within all the 32-bit boards that have been released, the SKR 1.3 has many advantages that have made it a success:Low cost. Barely higher than the equivalent with Ramps.

Note: Due to varying Board/LCD/Cable Header direction if the LCD does not light then rotate the plug end at ONE END (LCD side or board side) 180 degrees and plug it into the header. Do this for both EXP1 and EXP2 if the LCD does not light.

Now BigTreeTech has launched a new revision of these electronics, whose name is BTT SKR 2, to try to replicate the success of its previous version with powerful hardware and some very interesting news.

As we have previously mentioned, the SKR 2 is an evolution of the old SKR 1.4 introducing a large number of improvements and updates. Let’s go into detail below.

MCU, while its sisters SKR 1.3/1.4 mounted MCUs LPC176* the SKR 2 has improved this aspect including an ARM Cortex-M4 STM32F407VGT6 MCU at 168 Mhz that will give extra power to our printer.

MOSFETS, a very important part of our boards are the MOSFETS in charge of managing our bed and hotend as well as the fans. In the SKR 2 these have been improved using a HYG090N06LS1C2 in addition to additionally including a G045P03 that serves to protect the plate against possible thermal leaks.

WiFi, although its sisters already had a connector for the WiFi connection, in the new SKR 2 electronics it has been improved and made compatible with ESP12S or ESP07 modules. Especially for later use with RepRap Firmware.

Drivers, without a doubt one of the big changes in this revision on the old SKR 1.3/1.4 electronics is how the drivers interact with the rest of the electronics by including protections.

This unfortunately was eliminated in SKR 1.4 and forced us to “mutilate” our drivers in the case of axes other than X, Y or in the case of not using Sensorless, about which you can find more information in our

The first SKR 2 units called REV A had a design/component problem that precisely caused the failures that it was intended to solve in the TMC drivers.

This error was quickly fixed and all SKR 2 electronics for sale are REV B version (with the new component corrected). In the following BigTreeTechoffers three solutions that go from the refund of the price to the replacement of the affected components. You can find information about it in this other link:

Another important value of the previous values is that of CURRENTwhere we will adjust the current of our motors. You can also adjust them from the LCD from Settings/Advanced/TMC along with other options that we will explain below.

First check for our SKR 2 should be to review the power selection jumper, if you have incorrectly could create some functional issuesWe will useposition 1 (VDD) on normal printer usage powered by printer PSU (12/24v)

As always, we hope that the article has been useful for the configuration of these new electronic BigTreeTech SKR 2. You can leave your comments or doubts at the end of it.

without white cover and extra fan being off, the TMC5160 drivers easily reached 60°C @ 28°C ambient temperature, causing a hard reset of the SKR approx. 90 min into the prints on three different occasions.

hence, i opted for forced cooling of the SKR, using a 12 VDC fan (60x60x10), connected to the 5VDC output of the DCDC module. also tried a 12VDC impeller from a radeon graphics card, connected to  5VDC. air flow was massive, but torque noise was way too loud.
