Help needed with SKR1.4, TMC5160 and BL Touch Klipper setup

General Discussion
1

Hi all,

I have a Artirelly Sidewider X1 running a SKR 1.4 with TMC5160 and a BL Touch and a BTT touchscreen so after watching several videos on Youtube about Klipper I decided to give it a go.

I’ve installed Klipper on the Raspeberry and have started looking at how I go configuring the printer.cfg file, but must admit I’m a bit lost here on how I go in configuring it to take into account the BL Touch as well as the TMC5160, I’m also using a Bondtech BMG Extruder and a E3DV6 hotend, I’m currently assuming that for the steppers just renaming them would work but I would rather check here first before I go on a make the magic smoke show up.

As I’m a complete noob with Klipper, any advise on the correct setup would be highly appreciated.

Thanks in advance

It that helps, here my printer.cfg:

This file contains common pin mappings for the BIGTREETECH SKR V1.4

board. To use this config, the firmware should be compiled for the

LPC1768 or LPC1769(Turbo).

See docs/Config_Reference.md for a description of parameters.

Ok, seems like going through trial and error I’m starting to understand how it works, my only issue now seems to be related to the BTT touchscreen I’m using as I got it to work for several minutes but now is not showing anything except the screen type whereas I previously managed to get some info displayed.

this is what I’m using and I do have the [board_pins] config section

[display]

lcd_type = st7920

cs_pin = EXP1_4

sclk_pin = EXP1_5

sid_pin = EXP1_3

encoder_pins = ^EXP2_3, ^EXP2_5

click_pin = ^!EXP1_2

[output_pin beeper]

pin: EXP1_1

The BBT’s firmware and Klipper are not really compatible. You will need this firmware and a special [display] configuration to make it work.

Check the Wiki if your combination is already available. If not you will have to figure it out but the examples in the Wiki should give you an idea how.

Thanks for this Sineos, I’ll give a try and report back, for now I can say that I have the same config as the one tested by wildjokerss with the TFT 35V3 E3 and the SKR 1.4, except for the firmware; what I don’t get is why it started working until I did a change on the printer.cfg file that was not even related to the display section.

Below is what I currently have going on for the display and as you can see it matches what is on the Wiki and tested, I’ll use the firmware described in the link.

[board_pins]

	EXP1_1=P1.30, EXP1_3=P1.18, EXP1_5=P1.20, EXP1_7=P1.22, EXP1_9=<GND>,

sclk_pin: EXP1_5

I’d recommend the emulated_st7920

spi_software_mosi_pin: EXP1_3
spi_software_sclk_pin: EXP1_5

click_pin: ^!EXP1_2

will give that a try, thanks

Sineos,

Thank you very much, that did the trick, I did ran into a weird issue for a few minutes where I had white donuts going from left to right on all the screen until I rebooted the machine and all good since on that front. :slight_smile:

Thanks again
