  1. AN update on the problem, so like you sugested i printed the code that came with the printer but no luck. This means that the g code is not the problem. This leaves software, hardware or the motherboard. For the software i tried five differet versions of marlin and all had the same problem. For hardware i disconected the heated bed (i thought it might have been shorting the power supply), but that didn't help at all, i also checked all the conections and made shore nothing is overheating .The only thing teft is the motherboard, and i really hope it's not fried. The problem remains the same the printer works compleatly fine for the first hower or two (it sometimes even finishes short prints), but then it abruptly stops- the lcd screen freazes (the temperatures stay at what they ware at the moment it froze, and it says it's printing), the bead and nozzle stop being heated and all the motors turn of. I realy have absolutly no idea how to fix this so pleas help
  2. So... I have yet another problem I've not been able to solve on my own. For the past two weeks, I've only had one successful print (out of 14), and the worst part is that I have no idea why. The problem is simple: The printer just randomly stops mid-print (usually in the first 40%). Things I have tried: I've attached a reliable power supplies, I've checked the steppers and the drivers (all OK), I've tried to use a different sd card and today I updated cura to cura 4.0 and tried to print via USB. Nothing worked, but the last time I tried (with the USB) Cura gave me a crash report⬇️. In case it's important I'm using ender 4 with marlin 1.8.8. it reads: Error traceback Traceback (most recent call last): File "X:\4.0\build\inst\lib\python3.5\site-packages\cura\PrinterOutput\PrintJobOutputModel.py", line 171, in setState File "X:\4.0\build\inst\lib\python3.5\site-packages\cura\PrinterOutput\GenericOutputController.py", line 78, in setJobState File "C:\Program Files\Ultimaker Cura 4.0\plugins\USBPrinting\USBPrinterOutputDevice.py", line 329, in resumePrint self._sendNextGcodeLine() #Send one line of g-code next so that we'll trigger an "ok" response loop even if we're not polling temperatures.

  3. I have had the ender 4 for about two months now, it works ok, but i've encounterd an issue for which I can't seem to find a solution. Whenever I try to print a circular object it gets streched along one of the printers diagonals and compressed along the other (it becomes eliptical). the difference is not too large obout half a milimeter on a circle with a radious of 2 cm. but its enought to cause me problems. Solutions i have tried: Ive tightened all the bolts and made shore everything was correctly assembled, Ive tried upgrading the firmvare an did quite a lot of calibration,(the xyz calibration efect only the deformation in the x andy direction, so it dosnt do anything for me). For the slicer im using cura and iv tried plenty of different setings, but it doesen't seem to help. Is this an inherent problem for h drive printers, and is just a limitation i have to accept or can it be fixed?
  4. Thank you, I'll try to reduce power consumption. And do you think adding a powerful capacitor to the output of the power supply could help?
  5. I'm quite new to 3D printing and don't have much knowledge beyond the basics. I'm using Creality ender 4 based on ender 3. For the slicer, I use Ultimaker Cura 3.6.0 (I also use an SD card). So to describe my problem: Like the title says I've had plenty of seemingly random stops in my prints. It doesn't always happen (I've had about 3 failures for every success) The print starts normally and everything works as it should then suddenly without warning it stops mid layer, there is no error message and no option to continue the print. I've tried printing the same g-code many times and it never stops at the same hight so I doubt the slicer is the problem. I have two different hypothesis it either shuts down for a moment because of loss of power (i usually don't have this problem with any other machines), or it's overheating. the steppers do get rather hot (as hot as 90 C), so I have added heat sinks and reduced the current a little bit, but it doesn't seem to have helped.(do the regular nema 17 even have any thermal protection, because I don't think the printer has any kind of sensors on them). I know I rambled quite a lot but I really want to get this printer working as soon as possible.
