GearHeads Corner

I am resin-3D printing quite small gears (~15 mm across) for a small gear train. Because of the small size and the relatively soft resin I have set the height stub to 1.5 on all of the circular gears to get that little bit more bite. The circular gears all print and work fine.

However, the final gear in the train is a rack and I can't seem to find the same height stub adjustment for a rack, it remains persistently low profile no matter what I adjust: is there a way to make the height stub adjustment there?

I have attached a ZIPped version of my .gth file so that you can see what I'm doing, and a picture of the printed gears, where you can see that the tooth-heights on the circular gears are good but the ones on the rack are somewhat weedy.

Hi:

I'm not sure I put a depth adjustment in for racks.. Just checked.. I didn't. I will look into it though as it may just be a single box change..
I will be away for the next week on vacation.. but Ill check into that when I return..

Great, thanks!

Any progress on this one?

HI Romead:

Back to you soon, I dropped the ball on this and will check now..

Hi Romead:

I've made a version specifically for your problem. in it, you set a "Shift", this will clip your rack teeth on that dialog.
You can get this version by entering this in your browser..

Sorry for the delay,

Oh, just unzip that file to your gearotic folder to replace the original gearotic.exe

Ah, that's great thanks Artf!
