So I just drilled two quick diagonal holes into the cooling duct through the front two upper holes in my modified extruder mount and fed in two additional m2 bolts -> this solution works really well -> sometime later I will work on updating the design once I finish analyzing the function.
Usually I don't print over 25mm/sec but I couldn't find any flex in the new parts (there was a lot in the original parts) I wanted to see what happens whan I increased the speed. From left to right 50mm/sec, 100mm/sec, 150mm/sec, 200mm/sec and 250mm/sec. One interesting thing is that above 50mm/sec I have to turn down the fan speed or I get a bit of lift at the edges of some prints -> 50% max speed worked at all the test speeds today -> no lifting.
It seems from the quick tests that I can go to 250mm per second for most parameters but perhaps ought to drop back to 100-150ish for small perimeters.
Over the next days I'll start teasing out what the limits are for the different parameters.
It's such a good feeling to see the little printrbot going at these speeds...
