I love your logo (I'm 72 and had 6 years in Latin...) I decided to go similar to your way with the SD-card and will use a long adaptor cable to the front of the printer. Pity is I have my dedicated microPC (180*128*55mm) sitting inside the 3D printer so I was hoping to just use USB for convenience.. If this ARM32 is unable to redirect data to a buffer storage or sd card then that is the only solution. Shame on the Tronxy software engineers. Kick butt... And if the new tack plates will not do the trick (PLA sticks at room temp so I need hammer and chisel /not sickle!) i'`ll try a thin glass/mirror plate.

Seems nobody reads this apart from myself. So here is MY answer - the firmware of this printer is crap. Tronxy has implemented a USB (and - at extra cost - even a WIFI) but becaus of too high a transmission rate you cannot control the printer by these means, only just by micro sd cards. And as we all know, these slots fail very soon. I wanted to try the Toshiba FlashAir WIFI (W-03) card, but alas, they are no longer available. These would have been a very good viable solution - wireless data transfer to the printer, and then start the print manually. Would have been perfect. Just a dream which puffed into clouds... So, is there a possibility to activate the USB port to accept a data transfer to the SD Card? Can this ARM32 processsor be made to do the trick? VERY SMALL files (really SMALL ones) and only just a few layers can be printed directly from the computer, then the ARM32 gets overflowed and freezes. So, why not use the SD card as a data buffer? Other 3D printers are able to do this (eg. Flashforge, Dremel et al.). Somewhere in my old brain I think I have read that you can make this CPU to write its firmware/memory to the SD card - I am no software engineer, so I cannot follow this to any extent. In the meantime I am going to use an adapter cable (Micro SD to normal SD card) because this is much less costly than a new motherboard, and readily available too. The Tronxy engineers need a kick in the beehind to get their printers up to a useful standard. Mind you - hardware-like these 3D printers are getting better day by day. But unless they follow up with the firmware I would not advise anybody to buy one (with the exception - if you are able to swap the motherboard to something else and get it to run)

Thank you for your kind answer. I had the feeling that it had something to do with the USB, because I tried printing the same file to confirm my idea, and it did print perfect, no interruption. My thinking was that it could have been something in connection with my old PC (Compaq dc7600, Win 7) which had seen better days. It has USB-1 only, is slow and noisy like hell, and is going to be replaced by a new microPC in the next days. I'll go another route though - wireless, either with the Toshiba Flash Air WIFI 8GB SD card or, if this does not work, I'll try the the TRONXY proprietary WIFI-module - I do not like to swap these micro SD cards, they are a PITA, and when the slot gets damaged you have to change the board... No, thanks. I was hoping that USB would be THE solution as it was for me printing over 4700 hours on my small Dremel 3D20 without losing any steps. Maybe the slower data transfer of 9600 was responsible for no data loss then? The X5SA has ?no? memory builtin to buffer the print data and running at 115200 might be too much. Re. LCD/touchscreen - on the Tronxy X5SA pro it is OK and does whatever I need - no knobs, just a very easy to use UI.

I have to disagree with some of you. My TRONXY x5SA pro (latest edition 2021) is running quite fine with the provided 'Tronxy' software using SD-cards, but when I want to print with the more refined CURA 4.8.0 and USB the printer starts printing as expected, but stops in midprint after about 2 minutes, and does just heat the nozzle and the print bed, but does nothing more. Printer problem? I do not think so. This looks more to be a software problem as I cannot move the printhead with the jogging keys too. Maybe the problem is in the firmware? I don't know. I am at a loss. Can anybody of the wise gals and guys give a helping hand? Peter

My Printer is a TronXY X5SA PRO with the 330x330x400mm volume. The TronXY-slicer (which is said to be an offshoot of CURA) has no option for online print via USB - at least I could not find it. And using these small micro SD-Cards does function but is a real pain. Therefore my next step was to get the latest Cura version 4.8.0 in the hope to get the USB connectivity I had on my trusty old Dremel printer. Well, I found the profile for my printer, set the Baud rate to the appropriate 115200 and could connect PC and printer. Only to realize that there is some problem - after a minute or two the print stops without giving any information whatever the cause may be. Temperatures of bed and nozzle are as I had set - hot filament slowly oozes out of the nozzle, but the printer does nothing, reacts to no input and has to be restarted. All with the effect that I now have two holes burned into the bed surface. Any help will be greatly appreciated Peter

Flashprint is another possibility
