slic3r heatbed location start issue
-
I'm using the latest version of Slic3r 1.3 dev. I recently changed hotends and have not had this issue before the change. But nothing has changed in firmware or software. When I pick reprap as the gcode flavor, the print starts offset from where it should. I'd guess it's 10-20mm off. What would cause that? And how do I fix it?
-
Does your bed dimensions in Slic3r match what you have set for axis limits in config.g?
-
I did not. I just had it at 200x200. I hav a cartesian printer, so I set it no to 220x226. The reason being is my offset z origin is 16, 30. It doesn't look like anything has changed. My guess is the offset would matter. The current print started towards the front just like that last have rather than more in the middle as I specified in Slic3r.

It is still not working correctly after setting the parameters in Slic3r. Simplify 3d does the same. Is it possible it's something in the home all file?
Here are the parameters:

can you also post your config.g?

my offset z origin is 16, 30
Please explain what you mean by that.

I meant that when it hits the x endstop it travels 16 and y endstop it travels 30. That would then be the origin of 0,0. I'm sure something is wrong in the home all file.

@mlaustin6 : that means that your axis minima are X:-16 and Y-30, update your M208 command in config.g to get the correct 0,0 position
