Why is the default for 'Create Raft' set to 0.6 mm?

For me, and what I have read in other posts, is not even acknowledged by the print.
For me, it was trying to print, well, about 1mm above the raft with all Default settings for printing otherwise.
Others seemed to identify the same thing with older versions as well.

Is there a way to convey to MatterControl developers to set the default Create Raft to 0.1 mm to allow an adequate result? (without the print head floating above the raft)

For anyone else who uses Raft, I would like to hear some feedback as to what settings you are using and why. If you are not using 0.6, why is not the default 0.6? Is this based on other printers expected defaults and print function?

I am using the ROBO R1+.

Thanks

IT'S BEAUTIFUL!!!!

Thanks again to everyone that responded.

Interesting.

That was the version (1.5) that I just downloaded and seemed to be the latest version available from the DL site that it directed me for downloading.

Got your link though and downloading now. Thanks.
Will install after this latest print is done.

Yeah. Me too. Glad it was something simple.

On to another question, what version/license level software are you running? My interface looks like a paired down version of what you have and I am running MatterControl 1.5 - ROBO 3D and there is no reset anywhere I can find and a lot of your listed menu drop-downs are not available to me.

Finally got to this issue. Took forever get motivated and find the time for it.

Not sure what happened though but got it working again.

1. The filament - I actually found a great article for this (here). Much easier than anticipated.

2. Reinstalled the MatterControl software since there is not Factor Reset in it. Started printing right away. Trouble is I never changed anything in the settings (because I don't know what anything does) so not sure what caused the miscommunication from the software.

Thanks. I think that video might be helpful for the filament issue.
I need to dedicate some time to this and get it working again.
I found several other maintenance type pages here as well that I need to look over.

This is my first 3D printer and like it a lot. I am a novice so may be asking some simple questions.

When I got this I ran the standard general tests over a couple of days and everything was fine. Worked great and produced what I expected.

I hadn't used it for a few days and went to print and the filament broken at the filament input on top of the extruder. I pulled what I could out of it but there was a small piece left inside. I re-fed the filament back through the the filament input and fired it up.

Problems seen:
o Filament mechanism is moving as expected, but filament is not being pulled.
o Z-Axis is floating no matter what I try setting.

What I have tried.
Filament;
o I have reset the filament breaking off the end and reinserting but nothing is happening.
o Do I need to disassemble the nozzle to clean it? If so, how?

z-Axis
o I have tried several things and can Set Home and all switches are Triggered in G-Code as expected. When I run a print the nozzle floats above the bed about 1mm. I did find this article, but my sensors are not misaligned like what is depicted.
o I have reset EEProm back to Factory Defaults and saved, but nothing actually changed in the settings so nothing appeared to be out of spec.
o I have manually tried setting the threaded rod height for the sensors and this got me to 1mm, prior it was 6 or 7mm.
o When I set Home the Z-Axis is shown as -0.90. I do not know if this is correct or not.
o Has Hardware Leveling is selected.
o Start G-Code has "G29 ; Probe the bed" defined.

All settings are still default, Bed Temp = 50, Extruder Temp = 210, Filament = 1.75.

Thanks for any help in advance.
