Repetier host not generating propper g codes

rhinotek

Hi,

 I am using latest version of repetier host for my custom made 3d printer. when i slice my object with slic3r slicer.

it generates wrong g codes.

result is

after printing first layer, printer overlay other layers on a different location, means g code lost the origin of first layer .

any body help please,

Repetier

If the preview doe snot show this, I assume the gcode is ok. I guess you are loosing steps instead, e.g. travel moves are too fast.

Thanks for reply, my motor calibration is all ok because i have checked a print by uploading a sample g code from internet i was a simple object, printed perfectly. 

but when i generate a g code with repetier + slic3r . it gives me crazy coding

Repetier

But thats the point. If the sample gcode uses other speeds it may succeed, while your generated code may contains moves that are too fast. You need to check your slic3r settinsg and the resulting speeds and see if it is set to use faster speeds. Check generated gcode and read the gcode and you see where it happens.

Hi,

Nothing happened with slow speed slic3r settings, same issue, i noticed the generated g code program that X, Y location changed in second layer (i.e) far away from first layer origin.

also when i check the visualization layer movement in repetier host the layers extremely moves from one origin to another far away origin.

Is that a open GL driver issue?

Show a screenshot of what you mean. Could also be the problem. Moving to a unreachable are can of course also cause shifts in layer.

rhinotek

Yes it looks like layer shifting error, also let me know how to upload screen short of my problem.

You have to store the image somehwere (dropbox, pastebin, online foto album, ...) online and post the link.

kindly see my repetier settings and suggest, below are google drive links, Thanks.

and this is the G-code file generated by slic3r:

I saw your slic3r settings and I doubt your printer can run 500mm/s for printing. That speed cries for bad prints and lost steps.

rhinotek

Ok I have set the speed 15mm/s and could you please guide me the vibration limit setting , may I set 10hz or 0hz.

Repetier

I never used it and I did not programm the slicer. So I suggest letting it on default values.

Normal printing speeds are 30-60 mm/s. You use slower sepeeds for first layer (so it sticks better) and oute rperimiter as they are visible. Internal infill can be faster as it is invisible anyway.
