Almost done, I ran out of crimp connectors.... So that's for tomorrow.
Regpye, what setting do you use for the thermistor?
And I still need to get the extruder steps right. The summer temperature is messing with my head, it's kinda hard for me to think with a sintered brain... :-)

Alright, i have some catching up to do.
The pas couple of days i've been printing in the little spare time i had.
Some feedback on Regpye's hotend:
I started with the .4 nozzle that all printed very nice, absolutely nothing wrong with that. So then i moved to test the .5 nozzle.
At first it printed great, then after some time due to leakage things got a bit messy. Reg already told me to tighten it when hot and so i did, several times. and finally the leakage seemed to stop. So i printed more, speeded up, adjusted the temperature, and the prints came out very nice (a few boring calibration prints).
Then i discovered that there was more leakage above the heaterblock the PLA is now flowing out. The printing is just fine as long as i clean up the drops, though Reg, you might want to look deeper into this issue.
I'm now printing with .5 nozzle, 30mm/sec (walls at 25mm/sec), temperature 203C Maybe the walls are a bit to fast, the corners are not as tight as with the .4 nozzle.
The calibration cube i'm printing is with 100% infil printed with naturel PLA
And with this translucent PLA nice to see how good the infill is fused together. BTW this seems to be usable as a lightpipe although it is a bit yellow-ish.
So far for the first bit of feedback on the hotend.

I send the PM before i've read this,
I'll have a look at it tomorrow and see if I can fix it. After seeing that drawing i think it is what i described in the PM, I think it could have dislocated then i changed the nozzle's

Im having a fight with the slicers.
When i place the Rack and pineon part diagonal on the bed and slice it up then both slicer and cura manage to skew the layers, at first i tought it was slipping fishing line ore skipping steppers but it's really a slicing issue. when i turn the part 180 degrees then the skew moves along to the other side.... and when i print other long parts diagonal then they slice and print just fine.
What can be done about this?

2 turns just doesn't sound like it can grip the shaft well.
Make it 5 turns at least. I've never had a problem with this many turns. You might want to try that.
