extruder not running smooth over X

Post by scubamatt41 » Mon Dec 03, 2012 9:03 am

Hi all, The extruder on my up mini is not running smooth over X while laying down the raft. It pauses approx 1cm before and after the middle.
Middle being the platform middle. I took off the extruder head to see if there was friction in the carriage, I oiled the rods and bearings. I could not feel anything but maybe because it is to small to notice when you run the carriage manual or in the maintenance menu.
The hickup of the extruder seems to be gone after building the raft.

Could it be the nozzle-bed height? If so, should'nt it run through the whole object.
Did someone else encounter the same problem? What could be the sollution?

Sounds like you have the extruder height set too low and it is running into the bed. I found that the center of mine was significantly higher than the edges.

The Minis tend to be high in the middle. Also the middle of the perfboard tends to arch up in the middle when the heat is applied. Clip it down to step the flex under heat and redo your nozzle height calibration (I presume you are using 1.18 beta).

Try printing with 1.17 to see if it goes away. I have hesitations when printing raft in 1.18 on my Plus.

Hi does your hesitations have something to do with the extruder jittering when printing the raft.
Do you also have to click a new set value twice? For example: I was recalibrating the nozzle-bed height and I had to click every value twice before it was accepted!
Going 0.1mm up or down it didn't matter......double click or nothing?


WhatsUP with that :(

Lonv, Minis need to use 1.18 as they don't have mechanical bed levelling.
