Printer only works in dry mode

Hi,

My printer worked fine until yesterday. Now it only run in dry mode.

It allways stops after the skirt or if there is no skirt at the start when starting to print the infill.

Weird problem. Anyone a clue?

It has an printrboard rev d with repetier. Testet with repetier and octopi

Hi,

Can you clarify?

What do you mean by "run in dry mode"? Does it go through the motions for the whole object, but without extruding?

Does it actually print the skirt? What happens if the skirt is two or three lines instead of one?

And what do you mean by "stops"? Does the printer stop working entirely? Does the head stop moving? Does the extrusion stop? Does the extrusion motor stop moving, or just the filament?

Have you tried some other slicer (e.g. Cura?)

Have you tried with different .STL files?

Dry run mode in repetier host Its printing without heating and without extrusion.

It stops when when the first circle of skirt is printed (yes actually printed).
And when i dont use skirt it does the start code and then goes to the first object coordinate and stops

In dry run mode it moves like it should over the whole object.

No havent tried cura yet but i dont think its a slic3r problem. Why should it be?
Just normal gcodes all the time, i dont see any errors. Ive got the same firmware on my first printer, which works 100% fine.
Just that this one is 200x200 and not 150x150.

I did print before so i dont understand it

Now i think i can cancel things out. Its at M109 when the connection timeout accures...

The hotend it already heated up at the time this reaches it.

Things may stop for a few moments at the M109 because not only does the temperature have to be at the right temperature, it also has to be stable.

But when you print something with a skirt, it does print the skirt, which means it must be going past the M109. ???

What do you see in your communication terminal about the time the connection is lost?

Just looking at your Gcode... Shouldn't the G21 and G90 happen *before* you start moving the head? And the M82 happen before doing any extruding?

Hi,

thanks for all your help. Something in that repetier firmware had to be corrupt or something.

I know flashed with marlin dev. and it works -.-
