bmsaus4ax , thanks so much. That worked like a champ. I'm still puzzled by this behavior, however. I would have thought that if the clearance was below the width of the bit, it would automatically reduce the stepover percentage to remove the material. Wouldn't this come up in any case where the poc...

Hello, I'm trying to dado (make a groove in wood) to fix the top of a cabinet into the sides. I created a pocket, aligned with the top edge, and of the correct depth. When I try to cut it with an 1/8 inch endmill, i end up with material uncut in the center of the dado. This is also shown in this scr...

(Hoping this thread is still alive.) Just noticed a behavior I don't know how to cope with. When I created my own 1/8 inch endmill, with two straight flutes made of carbide, I input a chip load of 0.13mm for soft plywood. This calculated to a horizontal speed of over 6000mm/min and vertical of 3000m...

I think I discovered a bug in the use of %O in the Job->Output->Output File field. If the string "%d/%j_%O.shp" is entered, this is rendered, in my case, as "Job_Sides_1_2Ply_%O.sbp". I suspect '%O" is not being expanded when it's not at the beginning of a sub-directory or f...

To answer one of my own questions, and for future reference, the location for storing custom post-processor scripts, according to the Path: Writing processing scripts page , is ~/.local/share/FreeCAD/Macro for Linux users, which can be found under Edit->Preferences...->Python->Macro->Macro Path. Als...

Jipe , thanks for writing. I'm not sure your advice pertains to the ShopBot. According to the list of currently supported internal gcode commands , the "M6" command is not generated. Since this is the beginning of your gcode sequence, I'm not sure how this could work. However, this is dou...

jbraun , thanks so much for your reply. I'm beginning to think that separate processing files, for each tool, is the way to go. I think that if I set the origin to the origin of my project, and then load the file with the 'No Offsets' option, as long as I don't change the X and Y axis origins, but ...

Hello, all. I didn't get any responses to my earlier question about how to execute a tool change with the opensbp post-processor in FreeCAD, but I think I've figured it out. I think that I need to copy the opensbp_post.py file, found at https://github.com/FreeCAD/FreeCAD/blob/main/src/Mod/Path/Path/...

Hello, all, My next task is to cut the two sides of a cabinet from 1/2in plywood, using a ShopBot PRSAlpha and the opensbp gcode format. So far, i've been successful in cutting the back out of 1/4in ply. The ShopBot I have access to does not include a tool changer. On the sides, I need to use a 1/8i...

@turoj, thanks so much for the feedback. I, too, can now say that I've actually run an openshp file on a real live ShopBot machine and created a successful part. I also learned the hard way that I had to specify '--inches' in the arguments, after the carriage took off and banged into the rails. Than...
