bed levelling test

Recommended Posts

just an observation really, that caught me out.

i have the ultimaker control panel, so when i print, i set my temperature on that

and i set the cura temp to 0 degrees.

i used to let cura set the temp but when i got the ultmaker controller, i was always getting the temp error each time i tried to print. (seems to be fixed in v13)

i have been having some printing issues, not sure what yet, so i thought i would recalibrate the bed using the bed levelling check, but since i had set the print temp in cura to 0 it checked the four corner heights and when i set it to print the test square, it was OFF and away without setting any temperature. (since this was already set at 0) i hadnt set the temp on the ultimaker panel, since i was just looking for my problems.

it would be nice to have a default temp set in there for when doing the bed levelling

and also preventing it from being less than the melting point of pla / abs.

maybe even some text warning to say set the temp, at worst.

i hope that makes sense!

If you manually override the tempsettings in gcodes from cura you have to know what you are doing... I dont have the machine running when i calibrate the bed. i do this by eye checking the distance in 4 corners next to the setscrews.

needs some precision.. and of course has to be redone EVERY time after a rough Print removal or the buildplate has been removed from the printer..

i also level my bed manually, then i run the bed test to check the pla consistency over the bed. its a good belt and braces check.

you have to remember people starting out in the 3d printer world, you have to make it as simple as possible to start with, which cura does, then human nature makes us experiment more and more. for people starting out, they could easily unknowingly do the same and wreck their extruder wheel and setup.

i am just pointing it out, i am sure daid has a million things to add, but if we dont tell him stuff,there would seem little point in having a forum.

You cannot wreck the extruder wheel unless you use a hammer. The motor is not strong enough. And the firmware refuses to extrude if the head temperature is below 170C.
