BigtreetechTFT35 V3.0 Touch Screen Install - SKR 1.3 - Chris's Basement

[@MrHristoB]

I can tell you one thing Chris, there too many "reviewers" and "experts" on youtube, but the ONLY useful and practical tips and information is here. I'm totally new to this 3D printing buzz, started in November with restoring an old mk2 clone given to me by a friend. I'm not a stranger to electro-mechanical engineering and electronics (it's my full time job) but since then I've restored the good old mk2, configured and installed Marlin 1.1.9. Printed parts and built my own version of the LOG :-D (threaded rods and plywood), learned to configure and compile Marlin 2 on Platform.io, added WIFI and touch screen to the printers and so on.... And all thanks to the information in your channel. Pure information without the drama!!!! Great work man!!! Keep it up!!! Thanks for sharing with us !!!!! Regards

[@ChrisRiley]

Thanks is really great to hear! I am glad my content helps others, that's all I ever really hoped for.

[@johnlytle6633]

Hi Chris, your videos have really been a great help to me. There's not much on the web about updates for old RAMBo boards so I was reluctant to try to add the TFT35 to my old Maker Gear M2E. Your videos have given me the confidence to give this a try and I'm happy to say I got both the 12864 and touch screen modes working today. The 12864 mode was easy after I figured out the connectors were keyed backwards for my RAMBo v1.3. I had to do some research to find out how to hook up the the TFT cable to a serial port on the RAMBo but it was surprisingly straight forward. Thanks for your excellent instruction!

[@ChrisRiley]

Thanks John, glad you got it sorted out.

Thanks for the video! I've avoided the touch screens so far because I didn't like the idea of hanging two screens off my printer, or giving up the standard Marlin menus. I wasn't aware this one could do both! That's perfect! :D You sold me on it... lol I ordered one this morning. I couldn't find a link to it under the video, but I used you're Amazon aff. link to go and search, I got it with a coupon, total was $28 shipped. Can't beat that! I've already got the SKR 1.3 in my printer, so setup should be a breeze. Thanks again for all your great content!

Awesome! Thanks for using the link. This is a pretty cool little screen. Hope you dig it.

[@gpazbyte8553]

As always a great video Chris, I have this Touchscreen installed on my Hypercube with an SKR 1.3 main board and I love the way you can switch it. As you said there are uses for both modes, I leave mine in touchscreen mode most of the time for fast printing from the SD card, but I like it better in the old school mode for running with Octoprint.

[@ChrisRiley]

Nice! Glad to hear you are making use of both modes.

[@vhoward1122]

Thak you for putting out good info. Your channel is one of the few I check out when I need to find something I have questions on. I left Marlin firmware long ago when I converted all the printers I use to Duetwifi's and learned reprap firmware. Now I am building an old school i3 printer just for the fun of it and I saw these cheap 32 bit boards put out by BigTreeTech and decided to try it. You video's regarding how to configure and upload Marlin 2 via vs code are very good and to the point. Still a bit more involving to make changes to your firmware than the duets, but a good alternative for those who can't afford a duet.

[@ChrisRiley]

Thanks Vance for watching! I am glad the content works out for you. Thanks for the comment.

Dang man I wish you lived next door, maybe you wouldn't but thats another story. Love the education, you speak clearly and are a good teacher, thanks for the videos and all the work you put into them. Nice job Chris. Oh yeah sound levels, who cares, i mean really, I want it to work. Now a quiet lawn mower would be nice and some people go out of the way to make there cars louder. The sound of a well working machine is something to enjoy.

[@ChrisRiley]

Thanks for watching man, I "hear" you about sound level. It is pretty impressive what some of these drivers can do.

[@zevindd]

These screens are pretty cool, almost worth it just for the mainframe-y green on black look. Keep in mind though, when printing from the SD card attached to the screen, you're talking to the actual mainboard over serial, and things like limited bus speeds, CRC failures, and buffer problems can creep up for some people.

[@ChrisRiley]

Thanks Kevin, great point. That could be an issue.

[@Craigthepope]

FYI: Settings for TFT35 V2.0 to work on the SKR Mini. #define SERIAL_PORT 2 //Set to 2 to get screen to connect to printer #define SERIAL_PORT_2 -1 //Set to -1 to get octoprint to connect to printer

Awesome, thanks for the post.

[@pattr007]

when doing sound levels you should use a tripod and the same measured distance on all tests that way the tests are uniform. Thank you for this video. It has helped me to make my decision as to which TFT to buy.

Great Videos Chris! Concise, accurate, reliable, and complete! Wish the whole internet was like that. I followed your videos and I have been able to upgrade my Longer LK5 Pro with the SKR 1.4 Turbo with the BigTreeTech 2209's. I can connect to and control my printer through the Raspberry Pi that I have connected to it with OctoPrint however, my touchscreen display just keeps flashing "Longer", "Longer". I have tried making different changes in the configuration.h file but nothing seems to work. I've also tried switching the R & T wires. Nothing. I have the TFT connected as shown on SKR data sheet to the corresponding labels on the Longer TouchScreen (which functions from the factory with only 4 wires, no reset). I made a custom wire harness to get that done. I also tried loading the DWIN_SET from Longer onto the SD card but that didn't work either. Everything else seems to be controllable from OctoPrint thanks to your great video instructions. My apologies, this is my first attempt to modify and compile firmware. You seem to be very knowledgable so I was hoping you could point me in a direction. I am in over my head. Thank you and please keep up the awesome videos!

[@ChrisRiley]

Thank you! So you are using the longer touch screen that came on the printer or an after market one?

[@danieljmorel]

@@ChrisRiley Thank you so much for answering. The post was older so I wasn't sure you were monitoring it. I am using the touch screen that came with the Longer LK5 Printer. These are the numbers that I got off of the board itself (I don't know if they mean anything): HST0430563-7, TJC 4827X343_011_P03. These were on the chip: Ai HMI, T8, 20352035M0292. I have looked through the Marlin code provided in the example for Longer LK5 Pro but I can't see how the tft display is being called out. Also, when I comment-out "define Longer LK5 Pro" i get the following error: Sorry! FSMC TFT displays are not current available for HAL/LPC1768. I have also looked at the Alfawise U20 examples. I think Longer and Alfawise are somehow connected. As I said, I am in over my head. Searching the internet for this issue, tells me that I am not alone. I really couldn't find much regarding this matter. Thanks again Chris. Much appreciated!

[@ChrisRiley]

@@danieljmorel Hey there, so the longer screen might be a tall order to get working. The interface could be a lot different and the SKR board can't support it. Someone might have created a different firmware you can flash for that screen to get it going, give this a look and see if it might be helpful. github.com/Guizz27/DWIN_LK4Pro

[@danieljmorel]

@@ChrisRiley Also, I looked at the link that you provided, which was different from any I had tried, but unfortunately I can't do the update. My screen version is 0.3.1-DWTJ. He says NOT to do the update if the Longer LK5 Pro shows this in the "about" screen.

[@danieljmorel]

@@ChrisRiley I was able to get a Marlin download from the link you suggested and I was able to compile it for the Longer LK5 Pro however, the touchscreen remains the same: "Longer", "Longer"... I did try enabling some of the other TFT options but I still was not successful.

[@AndreasA.S.]

if you get garbled text after update, dont forget to include fnt and bmp folders on the sd with the .bin file. in fact you can make your own bmp files for the touchscreen.

I've tried on and off for years to get my TFT-35 e3 v3.0 to work with my SKR 1.4 Turbo board in my CR-10 S. The screen display was OK, but the graphics side always showed a "printer not connected" prompt. Recently I installed a SKR Mini e3 V3 board with Marlin 2.1.2 and I was determined to get it working. My solution was to set the Serial port to -1, set the second Serial port to 2, and leave the display as the factory CR-10. Now it's working perfectly. That is significantly different from your settings with the hardware/firmware you're using but perhaps it can help someone with a set up like mine who is desperately looking for answers. Caution: There are several flavors of hardware and you must use the one matching your equipment AND don't try to use a large capacity SD card for the set-up. I had to hunt through my old junk pile to find a small enough SD card; otherwise, the TFT-35 gave an error prompt even though the files on the SD card were correct.

Hi Chris, I have upgraded both my CR10S and my own Hypercube Evo build with this display. Everything works great except when selecting print in on the touch screen selecting the mainboard SDCard rather than the on board display reader the dialogue for bed and nozzle temp to not change so I do not know the current temp of things. Is there a fix for this? The temp readings work OK in emulation mode and when printing from the display SD reader, just not the mainboard reader. Also can I upgrade the display firmware via a firmware bin from the mainboard SD reader rather than the display reader, if not next time I renew the firmware it will mean taking the thing out of the CR10 control box to do this which will be a bit of a pain. Thanks Steve

[@ChrisRiley]

If you are printing from the SD card on the board I don't think the screen will get any info back to keep it up to date. There is no back and forth after it's started. Also, I think you have to update the firmware from the port on the screen.

I was thinking there was a pdf that showed each btt board and it’s serial port settings for each particular board. About a year ago I used the info to setup on a skr1.4 but now I’m doing an skr pro 1.2 and a btt octopus pro. I have 2 tft35’s not the e3 style that fits factory display. It’s got the knob to the side not the bottom. Thanks. Love your videos. They’ve been a big help especially for the custom boot screen.
