Smaller 3D prints after simplify 3.0 Update

[ozonostudio]

After Updating my software to the 3.0 version I notice that all my 3D prints are getting smaller at least a 90% smaller, this is not happening in the previous versions, and yes I already check and the preview show all the right sizes, but when I send it to the SD looks like something is resizing the model, anybody know why? I'm the only one with this issue?

Do you have a factory file? Or if you slice a 20mm cube using both versions and look at the g-code, is the output of the 20mm cube actually showing the dimensions as 90% smaller

As in your imports are smaller? Unless I've changed a setting in Blender (quite possible) I found straight after upgrading to 3.0 my imports are much smaller - they have to be scaled by 10,000 to reach the right size! (note that my blender scale is off, but it used to have to be scaled by 100 before). I haven't actually tried any STLs from Designspark Mechanical (the other program I use) yet, though.

I think what Tetraodon is referring to is just the fact that scaling is done as a percentage now instead of a decimal. So it's 100% instead of 1.0.

I ve got the same issue. 10% less .... on creatr hs

I'm using the same configuration than the previous version, everything its exactly like the pre version, but when I export to g-code, the sizes are a little different, and I really don't know what to do.

I'm not having this issue, but as was said above, just import a simple 20mm cube and create two gcode files - one from v2 and one from v3. Then post them both here. It would also be helpful to post your factory file for v3 so we can see your settings.

The comparison between your v2.2 and v3.0 gcode files will make it easier to give suggestions

i found this answer for creatr HS:
If your prints do not have the correct dimension when the printing process is done you will have to do the following steps to rectify this issue.

First connect the printer to your PC and then go to the communication window in Simplify 3D or Repetier or what ever slicing engine you are using and write the following command lines:

- M92 X66.67 Y66.67 then press enter;
- Now write M500 and press enter again to save these values;

The second step is to adjust the acceleration of the printer( once you modify the steps the acceleration on the X axis may be modified):

- write M201 X3000 and then press enter;
- then M500 to save these values.

Once you adjust the steps and acceleration your prints will come out at the desired dimensions.

You can find the 20mm cube for the V2 and V3 also the FFF profile that I use for both prints.

I forgot add the factory file from the V2
