Layer height greater than nozzle diameter redundancy #1828

Closed Rc72 closed 10 years ago

Rc72 commented 10 years ago

Working with tall thin extrusions(laser), This redundancy is preventing us from using slic3r. Is there any way to disable this feature?

Thank you for your time and consideration,

Richard

"redundancy"? I don't understand what you mean. Can you put more effort into explaining your problem?

Rc72 commented 10 years ago

Sure,

When slice settings are where layer height is greater than nozzle diameter, the slice fails. Prompt is displayed that explains error

We are printing a edge wound/flat extrude( synergetic polymerization). This is preventing us from using slicer for this reason.

Thank you, Richard

We can manually edit g-code ( layer height change)to allow printer to proceed and print is a success.

On Repitier's Gcode translator, file is displayed with gaps using slicer( to be expected) when manually edited g-code is viewed but part is solid once printed. Example with be a basic 10mm x 10mm x 10mm cube that was once hours to print at .05mm layer height by .05 nozzle is now 20-30min with 1mm height by .05 nozzle

I understand that in the future this graphic could be filled in if there was an allowance due to acceptance.

We are Interested in applying this to a speed fill/height for basic shapes to save time where layer resolution is not necessary due to 90deg outer perimeter walls.

@Rc72: I feel sorry, if I have missed something (for example what do you mean with "laser"?), but you really have got an extruder with a 0.05 mm nozzle (that means one twentieth of a mm, or about 1/500 inch)?

Slic3r is not intended to be used with laser cutters, so I'm not going to change anything.

You could just define a larger fake nozzle in Print Settings and then set your thin extrusion width in Printer Settings -> Advanced.

Thank you for your reply, and you consistent software updates. I apologize for asking a question that had a narrow demand based on our application.

You are correct, the advanced setting width was a solution and has been working perfectly. Once I gained familiarity with your application, was able to feed dummy variables in extrusion width fields to achieve our desired result.

I would like normals to have different layer height settings than high definition verticals one day. This would greatly help speed up printing in vertically flat areas to rapidly gain hight to allow for time to detail complex regions. There could be a hight tolerance input field after layer height field blank that told z height to increase and extrusion width to narrow to _when normals are greater than number of layers. It could force a tall wall in these regions only.

Just an idea, it may help fdm most of all.

Thank you for your unparalleled contribution in 3d printing. Sincerely, Richard Catalano
