Bed way too low?

Recommended Posts

Posted · Bed way too low?

Hi everybody!

Finally got my defective filament heater replaced and fired our Ultimaker Original+ unit up for the 1st time last night! What a build! We youtubed the entire assembly process, refined to a tee in 8 parts, that will be posted soon.

Last night we tried our first print, but the bed was way too low. The extruder emitted, the head moved in the shape of the part, both heaters worked. Tried searching for the answer here, but I got thousands of unrelated hits.

Some questions:

What have we missed? Why is the bed 15cm below the extruder when the print starts?

Also, the sound that the bed makes when traveling downwards is very different than when traveling upwards. More of a moan. Is that normal?

(We completed the paper adjustment of the bed)

Thanks!

not an expert here, but something might go so tight that the stepper is skipping

your extruder should be ~0.2mm above the bed, the nozzle will expand about 0.2mm when it heats up

instead of paper use a 0.1mm steel feeler plade used to adjust spark plugs, same thickness as paper but never wears out and does not leave paper fibers

There is a setting in Cura, under Machine/Machine settings where you set the z height of your printer. If this is wrong it may exhibit the problem you have, or smash the bed into your extruder :p
