Cook91c Posted May 3, 2022 Share Posted May 3, 2022 So I have a skr Mini e3 v3 with a Tft35 e3 v3.0.1 installed on my ender 3. Printer also has meanwell lrs 350-24, Dual z using both z plugs on bored and biqu h2. When I installed a bltouch v3.1 and upgraded firmware all my problems started. I get random freezing mid print. Tft35 will not respond at all. Hotend and bed continue to hold temp but there is no x y or z movement. I've tried several different bltouch firmware with same results. I can switch back to original firmware without bltouch and freezing goes away. Any recommendations on what I can do to resolve this issue?

BTT Tony Posted May 5, 2022 Share Posted May 5, 2022 Hi ， Thanks for your information. The printer work fine after switching back to the original firmware? Maybe it is matter to the bl touch ,Pleaes refer to the following link for the bl touch setting https://www.bilibili.com/video/BV1944y1h7Cn?spm_id_from=333.999.0.0 Quote Link to comment Share on other sites More sharing options...
Cook91c Posted May 7, 2022 Author Share Posted May 7, 2022 Issue ended up being the 32gb flash drives I was using. Its strang that they would only cause problems with bltouch enabled in the firmware. As soon as I went back to a sd card issue completely disappeared. Finished a 13hr print this morning with no issues. Quote Link to comment Share on other sites More sharing options...

Marc_Aus Posted October 24, 2022 Share Posted October 24, 2022 I just spent all weekend doing the same upgrade, and adding the Sprite Pro kit. Accommodating my existing X axis linear rail into the mesh limits made my ears bleed... FINALLY, this morning, started my first successful test print, from a 32G USB drive in the TFT35. Twice, at 2 different layer heights I had your issue. I have also found resetting or powering up with the USB plugged in results in a black screen on the TFT35. I will try the same file with an SD tonight, and again with a different USB drive. Quote Link to comment Share on other sites More sharing options...
Thomas Posted October 25, 2022 Share Posted October 25, 2022 I have the exact same problem as Marc_Aus, random freezes during printing and black screen on tft when having a sd card or usb stick inserted. I tried around 7 different usb sticks or sd cards but they all give the same problem. The workaround i have is to insert a micro sd card directly in the motherboard and print from there. Im using an tft 35 v3 with an skr mini e3 v3 Quote Link to comment Share on other sites More sharing options...
n0tr3adY Posted October 29, 2022 Share Posted October 29, 2022 Have the same issue. Printer freezes after 7 hours from (printing from SD card). TFT35 not responds for a long time then "printer not connected" or until power cycle. Strange thing is freeze happened an exactly same point at the end of the print.
