Matter Control E3Dv6 1st/2nd layer issues

Hey all,

I just recently upgraded to the E3D v6 head for my Robo3d. The issue was having was the 1st layer wasn't sticking to the bed but I fixed that with Mike Kelly's advice.

Unfortunately I am still having an issue with my 1st/2nd layer is coming out smaller than the rest of my print as shown in the picture below.



I have tried all 3 slicer settings in Matter Control and I received the same result, including calibrating it several times.

Anyone have any suggestions on what settings I should be using to combat this? This effects all my prints and because of this, Ninjaflex is a write off until I can get this resolved.

Thanks!

Looking at that skirt you look a little high on the right side. Maybe also on the left.

Does your printer have a cover on the bottom of it? If yes what is the steps per mm for Z in the EEprom settings

 

Hey Mike,

When I check my EEprom settings I get the error: There is no eeprom mapping for your printer's firmware.

As for a cover on the bottom of it? It's one of the newer sent ones. I received this printer in August.

 

Hey Mike,

Here is a video of the printer in action and a picture of the aftermath.

The eeprom setting decided to work for me again. I am not sure why it was giving me an error before...

 

Do your smooth rods run all the way to the top of the case lid?

If so you should use 2560 for the Z steps per mm.

 

I'll input those settings and give it a shot!

 

When I tried 2560 z step, it just makes a noise and doesn't move. Also when I exit the program and relaunch it, it won't save the value and keeps changing the z step back to 2267.72

Don't do that, they don't run to the top. Use the current value.

Your first layer still looks too high.

Okay I'll give it a read tonight, gotta head to work!

I'll give you an update when I can!

 

Sorry for the delay but I was able to fix it and the website you also gave me Mike was very helpful!


I had first enable automatic calibration, than adjust the settings to all 3 points until I was able to get a good solid skirt/brim.

I had a model that was basically the whole bed size and I was able to manually calibrate that way watching it go from point to point and raising it or lowering to my liking until I got a solid skirt/brim.

Also I had to go into the Custom G-Code and disable the auto bed leveling so my settings would stay. (I put a semicolon so the program would ignore the code: ;M565 Z0 ;G29)

There were also other factors as well that can throw off the calibration I found. Depending on the way you have your filament being held will effect can the print/calibration as well.
