This machine was bought to replace a broken-down DaVinci,  it was purchaced in a hurry without vetting the vendor first... and it has been nothing but problems since it arrived.   Rep-G is the ONLY thing that makes good parts... we can't even get the Maker-Bot software to do more than goosh plastic all over the place.

Right up until Tuesday we were getting repeatable results with the machine,  then all of a sudden we started having first-layer issues.   I don't know what changed between then and now but I'm tearing my hair out over it.

This is the ONLY machine we have problems with.   Hell our DaVinci JR runs circles around it most days.    The RepRap we jokingly built out of copying machine parts works better than this thing does.

The part that frustrates me no end is other folks have CTCs,  I've seen them run.... they were recommended by a number of people.    The one we got however... is a clone of a clone or a factory reject or something...  it has been apart and reassembled three times,  we had to replace the rods right out of the box and replace the aluminum plate.   One extruder stopped working entirely we had to swap things around to get it printing while our tech replaced the motor on the second extruder...   On and on and on.   

Now this latest infill issue.

Hopefully this gives us some sort of progress because I am at my wits end with this thing.

Ok for several reasons I have to use Rep-G on my CTC-clone, long complicated story I can't switch software right now.   That would solve a lot of problems,  but it is what it is. 

EVENTUALLY either I will get pissed off and smash this machine into splinters OR they will let me change the software... in the meantime...  I'm stuck figuring this out the hard way.

All of a sudden I am having trouble with my infill.   I was able to tweak the extruder speed via M108 and the head speed to get a good first/second layer "sometimes" but I am still losing quite a few prints to bad infill on the all-important first layer.

This is happening with materials that I run on other machines just fine,  both ABS and PLA.   So I know it's not the material.   

I've run the range from blue-tape to kapton to buildtack to glue-on-tape to (no sh*) glue-on-kapton-on-top-of-buildtack... Yeah I was having a bad day that day.     

I also know my bed is level, as I can get rafts to stick just fine, and the shell/outline comes out utterly perfect.

Basically rather than dick around with settings in SForge I want to edit the G-code directly,  it looks like I can can control variables related to the first/second layer but I'm not sure what the various lines do... or how the variables work.   Bigger, smaller, higher, lower...

I've attached the header and "first layer" code from a typical part I make.      Any and all help deciphering this is appreciated,  thanks in advance.

Look for Flowrateinfillmultiplier and set that for 1.0 then see if that makes a difference.

Because of the Mightyboard in those machines and its proprietary communication protocols I was forced to swsp out the board and LCD to something that would use normal software like Repetier and Slic3r.
