9 years ago Hello, I have done modifications to your data file (attached), that I noted with '!!' :
- For integration without main simulation modification while defining $bAllFrame = true; which runs module buildAllFrame() instead of original frame definition
- Replace my signature by yours ...
- Added name of designer (Sage) in title and removed host name
- Given host address in data and other link
- Removed comments for Rostock, which don't apply here
- Corrected data according Sage OpenScad files (Effector Offset, arm space, carriage offset)
- Taken into account 'htotal' to have accurate height simulation and travel
- Modified bed position to have the hotend touching the bed
- Given appropriate camera distance
Did you have any comments/complements before publication ?
Regards, Pierre

I really like your delta simulator & created a data set for a delta design I am thinking about building. I ran into a couple of limitations of openscad that I had to get around. In your Delta_simulator.scad, I added the new data set on line 108 as shown in next paragraph & had to comment out line 211 so the data_Delta-Six.scad file would draw the frame. I included a link to the data file and an animation .gif below. I also had to define: beam_int_radius = 236.506; rather than using a formula: beam_int_radius = frame_rad - 10;
Line 108 added: include //V-Slot Openbuilds Delta-Six by Sage Line 211 commented out Frame(); so the data_Delta-Six routine could draw its version of the frame.
http://www.zewind.com/data_Delta-Six.scad heep://www.zewind.com/V-Slot_DeltaAnimation.gif
Here is the link the build log the author & others have on this design: http://www.openbuilds.com/builds/delta-six.476/
Thanks for a cool openSCAD program,
David

I really like your delta simulator & created a data set for a delta design I am thinking about building. I ran into a couple of limitations of openscad that I had to get around. In your Delta_simulator.scad, I added the new data set on line 108 as shown in next paragraph & had to comment out line 211 so the data_Delta-Six.scad file would draw the frame. I included a link to the data file and an animation .gif below. I also had to define: beam_int_radius = 236.506; rather than using a formula: beam_int_radius = frame_rad - 10;
Line 108 added: include //V-Slot Openbuilds Delta-Six by Sage
Line 211 commented out Frame(); so the data_Delta-Six routine could draw its version of the frame.
http://www.zewind.com/data_Delta-Six.scad heep://www.zewind.com/V-Slot_DeltaAnimation.gif
Here is the link the build log the author & others have on this design: http://www.openbuilds.com/builds/delta-six.476/
Thanks for a cool openSCAD program,
David
