What's the optimal layer height for the MK2S?

I've read that printing at your stepper microstep height helps solving horizontal lines in your prints.

Is that true? How can I know what height is that?

Anyone has more information about this?

This is my ABS Benchy printed at 0.20 in an enclosure with Auto-Cooling and Fan Always On at 10%:

ABS = No Fan, ever...... unless it's 70c-80c air you're blowing at it (like a stratasys). the lines are probably from layer shrinkage or curling causing it to look like banding...

I get far better results with fan than without it.

This is without the fan blowing, compare with my results above.

Re: What's the optimal layer height for the MK2S?

You want a layer height that corresponds to a full step, so that’s a multiple of 0.04mm. In theory at least.

Nothing wrong with using the cooling fan for ABS, especially in an enclosure.

Your benchy does look too hot. Given that you’re using an enclosure try to lower the bed temperature a little.

Too hot.... using a fan is possible but it it's model, layer height and speed specific. i've had more parts fail with it on than not. they looked great but no point if they fail 10hrs on a 15hour print.... overhang/bridges will benefit but it should be fairly warm air... i've experimented with ceramic heater and metal blower fan at 60-70c as a cooling fan... parts come out great and no warping at all, even full bed sized parts. but gets way too hot in the enclosure for all the other parts of the printer.... plus electricity running a 1500w heater is a bit much.
