Z axis invisable wall issue

[ziconeo]

Hi everyone I'm new to this forum and I could really use some help.

I have a prusia I3 made by sintron

Ramps 1.4 board programmed with arduino firmware

For some reason I cant print past 100mm along the z axis. I should be able to go to about 180, but it always just stops. I even put in larger printing perimeters into my slicers to no avail. any help would be awesome!

Oh and can someone tell me how to view my current firmware installed on my ramps 1.4 so i can edit it?

You can't look at the firmware unless you have a backup of it. Reading the printer is not possible.

Can you wind it by hand through the full range when it is unplugged?

Noooooooooooooooo! that's what I was afraid of I was stupid and didn't back it up before uploading!

Yes I can, in fact, I can even manually move the z axis all the way to the top using pronterface. But when I print I cant get it to go past 100mm during printing.

I just tried again to make sure it wasn't a fluke,

changed the z axis limit to 180 in cura,

changed z axis limit to 180 in pronterface

made a 180mm tall super thin object and took out my filament

Pressed print and it went up to 100mm then the z axis shut off and the x/y axis's were still going

You have the limit set incorrectly in configuration.h

Probably these values:
// Travel limits after homing
#define X_MAX_POS 207
#define X_MIN_POS -20
#define Y_MAX_POS 125
#define Y_MIN_POS -38
#define Z_MAX_POS 50
#define Z_MIN_POS -5

That actually was the problem Last night I stayed up till 4:00am rewriting everything and testing. finally got it to work. I have another problem though, its different than anything Ive posted so im going to make a new thread. here was what I put in

// Travel limits after homing
#define X_MAX_POS 100
#define X_MIN_POS -100
#define Y_MAX_POS 100
#define Y_MIN_POS -100
#define Z_MAX_POS 185
#define Z_MIN_POS 0
