Bridge Testing
« Reply #15 on: May 08, 2017, 04:48:03 PM »
A recent print showed problems when printing bridges, I did try this before and do not remember what I changed.
Tests are here:

Results:




Still a bit of sagging, I had this already better.

Changed calibration after long time
« Reply #17 on: December 02, 2017, 12:15:34 PM »
To prevent too much dust in the printer I used this cover, which is a cover fo some outdoor grill:
https://www.amazon.de/gp/product/B01C682EPW/ref=oh_aui_detailpage_o09_s01?ie=UTF8&psc=1

After quite a long time I was trying the printer again.
There was no dust inside so the above cover works.
 :)

When trying the calibration points P0-P5 I realized that the calibration was changed somehow.
As you can see (partly) here the printer has a hexagonal heatbed:


This picture shows my normal setup with Kapton in the middle and blue tape at the right and left:


Here is a schematic showing the calibration points P0-P6 and the screws S1-S6 :


A Bosch Laser meter shows differences at the screws S6 and S2 in height, but the accuracy of this
meter is only +/- 1.5mm.
:-(

Jinx said I should use something like this :
https://www.amazon.de/dp/B01H035DRO/ref=sspa_dk_detail_1?psc=1

I will try to check if the heatbed is level in relation to the actuator.

As Jinx suggested I also tightened the belts here:

and the grub screws are ok already.
