never saw file trying to print, or filament type being used. but unless RH filament tab is set to PLA it should let bed temp be set anywhere to 110c PLA onlt like 70c

check the stl file in netfab for errors as this type gcode gets wrote sometimes if bad stl file or if I try to use skienforge to slice

also just because you can manually move extruder dont mean a loose connection wont tell printer to stop due to an issue

Thank you so much everyone (especially you IronMan) for your help!

Still sounds like sometning you need to address. For some reason your host or the printer is halting and failing to resume after a blocking call for temperature checks. You should try another version of RH or a different host. But you should definitely find the cause. Your printer shouldn't do that. It should successfully unblock after a target temperature has been reached.

In the meantime be cautious of heating up the hotend for too long before a print starts. The stock hotend is sensitive and could clog if left hot and not extruding for 15-20 minutes.

It was all you! Happy printing!

I appreciate it! Thanks again for the help.

I was a bit late on the reply!

So glad you got it...I never had to change that on mine for some reason (maybe cause mine is 2 years old and I did not have to deal with SD factory presets)

Awesome work, Smarch...persistence pays off!

Smarch, I will need to check your code against mine, but I cannot get to it tonight...I'm remote from my machine and I've got a ton of CAD work to do for my day job

Some other more Code-worthy members please weigh in!

In the meantime, read through this topic:

Might be some nugget in there for you...it's a bit dated, but code is code.

I tried it. Nothing changed. I have it echoing the lines as it goes through them, and no matter what lines I comment out it just hangs before it gets to the actual print.
The last line it echos when I take out the M190 line is the G92 E0 line.
So I tried commenting out that as well and it hangs on M82.
When I comment that out it hangs on G92 E0 again.
When I comment that out it hangs on the G1 line.
If I comment that out it just hangs earlier back at the G90 line.

Try commenting out the M190 line...this has caused issues with many in the past.

Here is everything that happens before the first X/Y movements.

Start code:

G21; Set units to milimeters 
G90; Set absolute coordinates 
G92 E0; Reset extruder 
G28 X0 Y0; Home x and y axis 
G1 X100 Y100 F4000; Center extruder above bed 
G28 Z0; Home Z axis 
G1 F3000; Set feed rate (speed) for first move

Sliced gcode:

; Please note that the first layer is set at 0.35mm to avoid sticking and warping issues. For further precision, consider adjusting this value to 0.3mm.

; layer_height = 0.3

; infill extrusion width = 0.42mm

G21 ; set units to millimeters
M107
M190 S115 ; wait for bed temperature to be reached
M104 S195 ; set temperature

M109 S195 ; wait for temperature to be reached

OK...can you slice a job and post the starting G-Code sequence?

Instead of just trying to describe it over and over I recorded two videos for you guys. First video is of what happens when I run a print, second is a video of my manually moving the printer head to the center and extruding.

Running some print:
dropbox.com/s/fzyrbnkg6ylqnd1/2014-11-12%2017.04.29.mov?dl=0

Manual movement to center and extrusion:

I thought that too, but when I move the hot end manually to the center of the bed, I can still move around after. In addition to the extruder moving to the center of the bed, the z-axis homes itself (as it should) but then just hangs from there.

Probable!

Check all hot end connections and wiring and make sure no wires are moving relative to the hot end when the carriage moves...as n2ri wrote, maybe your shorting out or disconnecting momentarily during the 1st move.
