So in a nutshell, try lower jerk and/or acceleration. The idea to use a nozzle with a larger hole was to try printing with rougher detail level at a faster speed, but also to see if it is possible to print. Also lower acceleration will increase the time it takes to get up to full speed and slow down again. So if you reduce the 'jerk' then the print head will have to decelerate to a lower speed. However, in practice the only time we have infinite acceleration is when instantaneous speed change (jerk) is applied. Each time the length shortens, the time to make it shortens too. Halve it again to 12.5 mm and it'll take 0.25 seconds and so on. This is useful for ensuring adequate cooling before printing new material on a surface. If printing layer time is lower than parameter value, printer will initiate a delay to reach the expected minimum layer time. The shape of this spaceship is very simple, but its structure is difficult to reproduce with 3D printing. The Enterprise has several designs, but this time it was the first one in the series. Thats the Enterprise, the spaceship featured in the movie Star Trek. Now as you move towards the corner, the moves get shorter so take less time. Minimal Layer Time: Definition: Desired minimum amount of time taken to print each single layer specified in metric hours. This design was created in commemoration of exceeding 10,000 registered users. I suspect you have acceleration and /or instantaneous speed change set high.Īssume for a moment that you had infinite acceleration and that you set a print speed of 50mm/sec. It doesn't get faster - it just appears to. Has anyone ever experienced this before? And can anyone guess what caused it? It did not affect the quality of print - it looks like it extruded proportionally faster as well. Again, the Simplif圓D preview and the actual g-code have no speed increase in it for this portion of the code either. I would say it reached double the speed it was supposed to be.

Then when it got to that side of the print for the 2nd raft top layer, it did it again. No G1 commands with any F in them except for one line after a retraction. I checked the g-code as well as the preview in Simplif圓D - there is no speed increase in either of them. But near the edge of the print when it had 8 or 9 back and forth lines to print, the speed increased gradually. While the top layer of a raft was being printed at 100% infill, everything was going great. Said in Unwanted speed increase near corner of print:
