Hi Steve, saw your beautiful clocks at the Maker Fair at Sierra College, ordered the SP13 when I got home, and the metal parts kit, but I am having problems with it running. I hope that the below information is helpful -
SETUP
Slicer - Orca and Bambu Lab (tried both slicers one at a time with the unused slicer left off, so there would be on conflicts when making the new escapement wheel)
2. 3D printer - Bambu Lab P1S, 256x256x256 so no split parts
3. Print speed - Printed with 50% speed on the P1S for the best quality, it really looks great!
4. Used suggested 3d printer settings on page 12 of the build manual, including Arachne. (examined gear teeth in both Orca and Bambu slicer, they look exactly like the teeth shown on page 9 and 10
5. Ran drill bits supplied in the metal kit through all holes in back and front PLA frame
6. Filament used was PLA Silk, SunLu brand
7. I have 6 pounds 4.5 ounces of BB's in the weight column, and 44 cents worth of pennies in the Bob. Used the mid length, lower, and upper pendulum parts
8. Checked that all ball bearings spin freely on their metal axles
What I noticed:
Difficulty with pendulum striking either the wall or the weight or both- This issue resolved, but even with adjusting the lower "feet" that ride against the wall, there is very little clearence between pendulum, and the weight, like 1/8 inch - is this normal?
I noticed that the minute hand is just barely able to stay at 1:00 o'clock position, it is VERY loose, but moving it one full revolution, the hour hand follows as it should for all 12 hours.
Gently starting the pendulum swinging, while applying a slight pressure to the escapement wheel in the clockwise direction causes the escapement wheel to turn by itself for no more than 18 teeth, before stopping.
I meant applying slight pressure in the COUNTER CLOCKWISE direction results in a nice Tick-Tock sound
