Hi, On each print, the hot head freezes after changing layer. It seems the more time passes and the more it freezes. Less than a second freeze at the bottom and several seconds at the top.
On each freeze, some plastic is still extruded by the nozzle, leaving a bubble of plastic at each start. This makes the nozzle kick that bubble every time and makes ugly plastic spots all over the Z axis.
Regularly, around 98%, it won't recover the freeze and stays at starting position, making a big bubble.
If I pause the print, it takes a looooong time to actually pause and park the head. Then I can remove the big bubble and resume again... That crashes the LCD, it reboots on the resume print but showing 0%. If I hit resume, it goes to the right place but won't resume at the same spot, its like it missed a line.
I think I am using the standard Cura setting with PLA+ : 0.3 nozzle with 0.2 layer.
No temperature trouble when freezing, on both the bead and the head : no more than 1°C difference with what needed and most often 0.
Anyone experience this trouble ? Some Cura settings that could do this or correct the trouble ?
This seems to be a bug in the screen firmware. After the screen crash and reboot, re-printing will give a perfect print, with no freeze.
It's a shame because the first crash takes more than 6 hours to happen.
I’m having this problem too. Is there a fix and if so how?
Yes. There is a fix. Just forget that display and use OctoPrint instead.
It seems that the display and the firmware is provided by a Chinese manufacturer which seems not to be interested to provide a working product.
@Sinspin makertech sent me an email suggesting Trying a new sd and gcode. Also found the touchscreen firmware update. So far it’s working fine. But I’ll definitely try your method. Thank you
This pointing on changing to another SD card is a bit, lets say, sanctimonious. Because they provide the initial SD card. If they would provide an Sandisk card instead of an no name card then would that case be almost impossible. I use Sandisk cards since more than 10 years. Even Samsung cards failed, Sandisk never.
OctoPrint have some advantages compared to the internal module. You can just upload the print files by dropping them in the browser.
Wifi enabled, as long your RaspberryPI can it.
Selecting a file from SD card is (at least with my firmware version) difficult since the names are cutted in the overview. Not with OctoPrint. Easy selection, showing details, statistics if once printed.
There are plenty of addons available. And since it is an open source project, everyone can extend it.
That's finally what I did and worked fine since : took Octoprint and forgot the touch screen.
Never had that problem anymore.
