Hello everybody,
I'm trying to print a file but after 3/4 printing layers start to split.
See picture!
I'm printing ABS at 235C flow 0.96 and no fans and a 100% infill.
why does my print split like this and what do i have to do too prevent it.
I see a few issues. You are printing too fast for your printers hardware. The after images or ringing as it is called around those holes are caused by your printers frame vibrating from the motion of the head which means you are going too fast.
The separation is caused by uneven cooling which is common with ABS. You need to have the print stay the same uniform temperature as long as possible and then cool slowly. This means keeping the printer closed with a heat source inside like a 100 watt bulb. or keeping the printer inside a cabinet where the temperature can be controlled and kept as warm as possible.
What temp is your bed at? Have you calibrated your feed rates and motor esteps? Is this a stock machine or converted?
It looks like you have over extrusion issues as well. The layers look like they have over lapped. They should be very visible and defined. Your machine is putting out way too much filament per layer.
It is a stock Da Vince 2.0a with repetier frimeware.
And my travelspeed is 130mm/s and normally my flow is set to 0.91.
But the layers also started splitting.
Allways the first layer after the holes lets go.
My bed is at 105c.
I will try with a lower speed, like 100mm/s and the flow back at 0.91
I have tried the feeder calibration. But got it only went down hill so i rolled back to my working settings

For a Da Vinci printer even 100m/s is way to fast. The most you should try on a Da Vinci is 60m/s.
When I had my 1.0 I had to bring it down to 40m/s to avoid any ringing. These are not production rated machines and are not for people in a hurry or trying to make a deadline or anything. If you want a fast production level machine then you need to be prepared to shell out $800+ USD.
The Da Vinci's are mostly for people who want to print trinkets or toys for their kids. Maybe artsy things and various gadgets but done so slowly. I would also use PLA when ever possible as it is much more forgiving when it is hard to maintain cabinet temperature.
The layer separation is due to uneven cooling. You need to come up with a way to maintain a high temp around 140F inside the printer or put the printer in a cabinet where that temp can be maintained. The issue with heating the entire printer is you run the risk of overheating the motors and their steppers which will result in layer shifting and failure.
I agree with Carl that your layer split is due to uneven cooling. The cause of uneven cooling can be complicated since your Da vinci 2.0A is enclosed. In theory, you should not have uneven cooling if you preheat your bed long enough. Some factor can make things complicated.
1. You are printing in very cold environment such as basement in cold place.
2. You leave your printer Front or Top cover open or even have the layer cooling fan or case fan mod.
3. You open the front door or top cover in the middle of the print and suddenly bring in cold air. (I notice the split happen relatively high in top)
