TronXY X5SA PRO with CURA 4.8.0 stops printing after a minute and freezes

Posted · TronXY X5SA PRO with CURA 4.8.0 stops printing after a minute and freezes

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

    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)

      • S-Line Firmware 8.3.0 was released Nov. 20th on the "Latest" firmware branch.
        (Sorry, was out of office when this released)

        This update is for...
        All UltiMaker S series  
        New features
        Temperature status. During print preparation, the temperatures of the print cores and build plate will be shown on the display. This gives a better indication of the progress and remaining wait time. Save log files in paused state. It is now possible to save the printer's log files to USB if the currently active print job is paused. Previously, the Dump logs to USB option was only enabled if the printer was in idle state. Confirm print removal via Digital Factory. If the printer is connected to the Digital Factory, it is now possible to confirm the removal of a previous print job via the Digital Factory interface. This is useful in situations where the build plate is clear, but the operator forgot to select Confirm removal on the printer’s display. Visit this page for more information about this feature.

      • Ultimaker Cura 5.6 stable released
        Cura now supports Method series printers!
        A year after the merger of Ultimaker and MakerBotQQ, we have unlocked the ability for users of our Method series printers to slice files using UltiMaker Cura. As of this release, users can find profiles for our Method and Method XL printers, as well as material profiles for ABS-R, ABS-CF, and RapidRinse. Meaning it’s now possible to use either Cura or the existing cloud-slicing software CloudPrint when printing with these printers or materials
