Follow-up to my prior post: yes, found a way to do this permanently, so there’s no need to fiddle scaling settings for every model. Adjust the steps-per-unit values in the gcode console:

M503 (displays current settings — you should see a line that starts ‘M92 X132.333 Y132.333′)

M92 X133.4 Y133.45 (sets new X/Y steps-per-unit slightly larger — other values will be left unchanged)

M500 (saves changes)

Your numbers may vary. I made a test model — 120x120mm square, with a 90x90mm square hole — printed it, took several measurements with calipers (inside and outside at top, bottom, left, right), scaled the original 132.333 values by the average differences in scale and then printed again (retested a couple additional times to arrive at these values — and notice that X&Y aren’t quite the same). Made a two-piece press-fit case, one side printed on the Robox, other on Printrbot, the two click together properly now, mounting holes align with circuit board.

You can use M502 (and then M503 to save) to restore the original factory steps-per-unit values.

The first of our experiments is as follows:

 

Filament slip threshold is a number which will currently present an error popup when it is exceeded. The default value is S100.0 which is far beyond the expected slip to basically disable the feature..

To see this setting you can open the Gcode entry panel and type M503 followed by enter. You will see a lot of information appear, we are working on the last few lines which say:

Filament slip threshold (mm):
  M909 S100.0

What we want from this experiment is to find your best slip threshold setting. Once we have this we can program events that will occur when the threshold is exceeded. Right now you will see a filament slip error popup while plugged in or a pause if the printer is not plugged into USB.

 

If you want to take part please change your filament slip threshold by entering the following commands at the end of each line press enter or the “Send Gcode” button . If a different firmware version is loaded it will overwrite this value.

M909 s100.0
M500

Replace “100.0” with your setting, “0.0” is too low, “50.0” might never show the error. M500 saves the setting, M503 will display the current settings.

Please reply with your “M909 Sxxx” setting and result following a print. Please indicate the material type you are using. If your nozzles are not flowing well or your extruder is not from the current build (ie a beta unit) your data will not be valid.
