Steve does the SP7 ELECTROMAGNETIC CLOCK print in CLASSIC or ARACHNE mode. Also does it make it any more reliable if the gears are printed 100% solid vs. 30%. At this point I didn't care how much filament I use. I just want to try and get this within a few minutes off a week. I have a much stronger pulse to the pendulum since I made it electric. But still can't seem to zero in on getting an accurate timing even just per day.
Any thoughts? I think this clock should be renamed "The Tinkering Clock" lol...
If the manual doesn't mention classic or Arachne, then it was likely designed before Arachne existed. Therefore, it was probably optimized for the classic slicer. Look at the slicer to decide which one prints better. If there are tiny dots of filament at every "T" shaped intersection, then switch to the other mode.
Most of my gears are designed so the main gear becomes completely solid when printed with 3, 4, or 5 perimeters depending on the overall component thickness. If the gear was designed for 4 perimeters and you print it with 3 perimeters, there will be a very narrow infill sliver throughout the gear. It prints faster if you switch to 4 perimeters. The only place where infill should exist is where an arbor expands out to create an integrated pinion. 30% infill it perfectly safe in those areas.
Yes, this clock could be called the tinkering clock. It is the fiddliest of all the clocks. It can be quite reliable once it is set up. I had all my clocks on display at a Maker Faire. The stepper motor clocks are obviously the most reliable, but the EM clock was the next most reliable. The wind was affecting the wall clocks with long pendulums.
