Hi Dave..et al..
It could be that CamBam puts out small arcs in some spots. ( GM does the same , but puts out a G91.1 to ensure the Increment
al direction is set right. )
CamBam may not put out the arc direction ..perhaps
..so you may want to check that. If it doesnt show up in a dxf, then it shouldnt show up in the GCode.
Thanks, Im happy to hear yours is going to work. I got about 7 tick tocks today on mine. Unfortuna
tley, a plastic clock with plastic shafts is just too hard on the shaft friction. I fear Im going to have to redesign with bearings on the shafts. But after getting 7 seconds of motion its clear to me that the escapemen
t works as designed, so Im relieved to report that much.
Thats the funny thing about a clock, the first big job is the design.. gears and escapemen
t, I think after watching video #1 anyone could design one
with a bit of practice. Making one.. is also a major job. I had forgotten since my first, just how important the friction feedback is over the run of the ratio'ed gears. Im going to redesign with pickyness to get that down to where it will do the job. So Video #2 will be delayed while I redo it all with the aim of having one running that I can use to point out all the pitfalls one might not suspect they will run into. Things like sharing a shaft for the second and minute hand, but ensureing no weight is put to that shaft unless its well hung on bearings.
. things you should look out for. I think thats the next step in getting more clockmake
rs out there, and Ill focus on that for the next couple weeks while I study grasshopp
ers a bit more. For example, a deadbeat gear really should turn just by blowing on its teeth if its well hung.. mine is close to that, but needs work
Glad to hear things are going so well,
