Solved Printer not printing first few layers or out line

I recently installed a new hot end of my 3D R1 plus and everything seems fine except that it doesn’t print the outline nor the first few layers of the item that I am printing. The item is one of my own design and I printed many times before that’s how I know that it’s not printing the first few layers. I printed two of the calibration boxes and according to my calibers they are both .378 “high if that’s helps and the printer didn’t print out the outline ether. As far as I can tell it touches all the points on the printer bed when it’s starts to print.

 

That sounds like a slicer setup issue. I can't see how changing an extruder would skip the skirt and layers

 

Is the bottom still solid on the part or does it go straight to infill? Are you using Matter Control? Is the part starting below the bed line in the slicer software?

 

Thanks for getting back to me so fast. Yes I am using Matter control and the bottom is solid but on one of the boxes you can see the infill. All so Z offset is set at 0 mm and what should it be set at?

 

I set the Z offset to 1 mm then printed anther calibration box and I got the out line but the bottom of the was not solid. Changed the Z offset .5 mm printed the box again and got no out line and the bottom of box only some what solid. Next I will try 1.5 mm see what that does.

 

Thanks I will keep playing with it
