<p>I need to print parts that fit together very well on the Longer LK5 Pro. However, after printing a Benchy, I noticed that whatever I print has a lot of imperfections. Is there any way I can fix this? All I know about the printing conditions was that I was printing at 230 °C nozzle temperature with 60 °C bed temperature. I was using PLA+. I was also printing the Benchy file that comes with the Longer LK5 printer. I tried tightening the Y-axis belt, that moves the bed, and the wheels on the bottom of the bed.</p>
<p>Here are pictures of my Benchy:</p>

This feature writes to the SD card at the start of each new layer, stalling the print for at least a significant fraction of a second with the filament unretracted, which will make a nasty blob wherever the toolhead happens to be positioned. Absolutely turn this off. It\'s impossible to get quality prints with that feature on. If there\'s no menu option to turn it off, you\'ll have to rebuild the firmware or get alternate firmware from someone else.</p>\n<p>It looks like you have moderate overextrusion. If the esteps were tuned, you probably adjusted them too much in the direction to increase extrusion and should reset to the factory setting and calibrate again, erring on the side of less extrusion rather than more.</p>\n<p>There are a number of places (especially on the cabin) where some walls are inset relative to where the wall was supposed to be, and where it\'s present in other layers. This is almost surely a result of losing material to oozing in the interior of the model, as a result of &quot;combing&quot;. See <a href="https://3dprinting.stackexchange.com/a/11005/11157">this answer</a> for details.</p>\n<p>On the hull (especially the bow), it looks like you might be experiencing the consequences of numerical precision bugs in Cura, which result in erroneous tiny segments that break up smooth traversal of curves, leaving blobs where the toolhead stutters. Watch during printing and see if the nozzle is stuttering (suddenly slowing down then speeding up again) along these curves. If so, make sure the Maximum Resolution and Maximum Deviation settings are 0.5 and 0.025 respectively. These are the modern Cura defaults that avoid the problem, but some profiles (and some older versions of Cura) have values that trigger the bugs.</p>\n'}, {'answer_id': 19812, 'author': 'printerGuy', 'author_id': 35141, 'author_profile': 'https://3dprinting.stackexchange.com/users/35141', 'pm_score': 0, 'selected': False, 'text': '<p>Just got an LK5 and printed the included Benchy gcode. It looks pretty similar to the benchy in the pics with some of the blobs in the same location. Then I downloaded the benchy from Thingiverse and sliced it with the Longer 1.3 Slicer. Pretty good results from doing that but it took longer to print.</p>\n'}]
