Solved Robo 3D r1 (nozzle touching the bed)

Hi. I just bought my Robo 3D R1 (upgraded version). All went well until i was trying todo my 1º print, the printer goes around trying to print but the nozzle touches the glass bed. I tried cura and the nozzle looks like only starts to print on the 2 pass.
Can someone help me?

Thanks, Nuno.

 

I was looking at mine thinking it was touching but when I put my face way down there an looked it was actually a very thin layer of plastic. And in fact what I thought was scaring was just a micro thing layer of extruded plastic laying over my print. After switching to Cura this has become less apparent.

 

Thanks. I added the g code to Matter Control but it touches the bed when is starting calibration( the dots on the bed).

 

Thanks. Its normal that it looks like it bends the glass bed a litle? if its normal the gcode to lift the nozzle do i go up on the number or down? M565 Z-0.6

 

Thanks. i will try like -1.2 or so. i tried -0.9 but didnt do good

 

It worked. but i have an issue when the printer does the last calibration point it drags the nozzle on the bed making noise until it starts the print in the midle.

 

All solved thanks"!

 

How was the problem with the nozzle dragging on the glass bed solved? I experience the same problem!

 

I just had the same problem. Add something like this: G1 Z5.0 to the end of your "Start G-Code under Settings, Printer, Custom G-code in Matter control, or elsewhere in other software.

The printbed flexes a bit during leveling. It's not bending the glass, just taking up some slack in the mechanics of the Y axis. Don't worry, it's normal.

 

Thanks, I will try this.
