I’ve recently been troubleshooting my mini2. One of the things I did was upgrade to the latest firmware. Oddly, it seems to print really slowly - that is it moves in small jerks, pasing maybe a tenth of a second in between, when before it would run continuously. Sometimes during the print it’ll print normally, but most of it seems to consist of this print / pause action. It’s not clear to me why it gets so slow in some parts, because it will often speed up while printing essentially the same g-code on successive layers. I had at first thought it might be due to the nature of the layer’s g-code, but that doesn’t seem to be the case.
What’s especially odd is it will do this as well when it’s printing the initial skirt (at least for part of it, if not all of it).
I’m using CuraLE with my Mini2, I have my Z-offset set to -1.15 with an initial layer flow of 90%, a layer height of 0.15 and 100% infill. Otherwise using the standard / normal PLA profile.
I suppose the main question is, are there any conditions which might cause the mini2 to execute g-code in small steps with pauses in between? I’m fairly certain the issue isn’t with the slicing, here.
