Topic: The Extruder skips only during the first layers.

Any ideas  I'm extruding at 245.  250 does the same. Any suggestions?  http://youtu.be/T9Frkg2mOrU

One possibility: If there's too little clearance between the nozzle and bed on the first layer, it can cause back pressure that stalls the extruder. So check the clearance, or measure your first layer thickness.

That was one thought I had.  My first layer with the natural abs looks really thin. Almost transparent.
Thanks I'll re  calibrate tomorrow.

I had that exact problem.  My offset was too high. Backed it off ~0.1mm and it's all peachy now!

I finally got around to assisting the z offset and it didn't seem to help.  Are there any other issues that may cause this during the first few layers?

Have you tried lower bed temperature?

Neil,

I have the same issue. no fix yet. watching this thread... the first few layers show the extruder stalling once in a while. then once i'm a few layers up, the extruder stops grunting and the little wheel stops turning the wrong way!

I'd love some ideas from others.

cheers

Re: The Extruder skips only during the first layers.

I finally got some success last night.  Cleaned the whole bed. I was using a glue stick before. I applied hair spray to the newly washed and dried  glass bed.  It wasn't aqua net or anything mentioned here just something extra hold aerosol.  Then i re-ran z calibration.  I got my offset set to 3.53. The lines didn't look perfect but i picked the thickest one that stuck to the bed.  For me the number of the line I picked stuck but the line didn't too well.  My next print started off good until my y axis skipped, but the first layers went down well. Hope this helps.

Glad to hear you got some success

For your initial offset, can that be entered manually or did you start at 5 like at default and then worked your way down to 3.53 by re-running the process?  Did you apply hairspray when bed is cold or hot?

Thanks

How did you assist the offset?

I'm having same problem, but I think it might be my choice of hairspray

That was auto correct mistake.  It should have said adjusting the offset. I used the soliprint z calibration.

IT can be entered manually just type of in the box in the top left of the z calibration screen.  After running and choosing the best line make sure to hit the "set new z offset"  button. In the bottom right.

I do that, but after entering manually and hit run it jumps back to default before running, are you using 1.1.1?

Re: The Extruder skips only during the first layers.

Yes I'm running 1.1.1

I have the same issue, first few layers then it's solid.
