I have a Ultimaker original. Lately I am having the problem you see in the picture. The outside layer is not connecting to the internal matrix in some areas. Some parts the side is loose and only connected at the corners. Anyone seen this or have a fix?
Its hard to tell from the angle, are all the rows of extruded plastic the same width?? Perhaps your extruder not pushing enough plastic??
I agree with @Michael_Shadow_O The layer shown looks like solid fill with a too lean feed.
Looks like backlash, your belts get lose over time. Check the tension.
Flow is 100% Could be the belts. It is printing right now, but I will adjust them and see if that solves it.
It looks like your insides are not connecting to eachother either. I think the difference is about the same. I was in denial about it being the best solution for a while, but I would say you need to decrease your nozzle size in your slicer settings until the people making the slicers give us either a “distance to next row” or a “dye swell” setting. The slicer settings simply do not take into consideration dye swell, so the extruded plastic is not as big as the nozzle diameter.
Your print has inconsistent distances between rows too. Belt tightness, jerk settings, backlash and stuff could possibly cause that.
I am guessing your shorter rows print better than your longer rows? If so, crank up the heat a little bit. 5C, probably.
Some slicers have a setting for how much the perimeter and the infill overlap. Check that.
The inconsistency really makes this confusing. I was only printing on and off since August, so I am honestly a bit of a newb, but I wanted to chime in and try to help anyways. Take this advice with a grain of salt.
Sometimes it depends on how the slicer reads the file. This was especially bad for me with the latest Slic3r.
Does it go away when you print at half the speed? Do you also see the problem on the top layer?
I’m having the same issue with my printrbot
Most likely, backlash, because of slack in the short belts. Check if the short belts are tight, else press the motors down while screwing those tight. (On the Ultimaker that is. On the Printerbot from @Anatoliy_Pishenin the belts most likely need more tension)
It’s the most common cause of this behavior, and the infill lines not connecting every other line also indicates this problem.
Are your x and y steppers calibrated properly?
Thank you for the input. It turned out to be several things. I thought the short belts were tight, but tightened them again. That helped, but I still had problems with the material not blending together. So I raised the temperature to 225c and cleaned the Bowden tube and adjusted the feed system. I also raised the flow % to 110. Seems to be working fine now.
Can you post a picture of the print now. Fixed outcome
