More perimeters = more strength in FDM printing. For rigid plastics like PLA
that also increases stiffness.
Several years ago, Benelli was designing a new auto loading shotgun and they
had a problem with part of the bolt breaking. They made it thicker serveral

probably want cyclic synchronization communication, messages are sent anywhere
within communication period and start to be used then synchronization message
is sent. Synchronization message may have som jitter, it does

Thanks for the replies...
The question was around slower RS485/CAN. I'm seeing a lot of actuators

I have had two of similar design in service for about 3 years now and both
seem to work just fine. Filling them is the only real nuisance as I
mounted mine in the base of the machine. Keep them very accessible if you
can.

I guess they are worth the try. I really need the automatic one because

An off topic question, not directly LinuxCNC related...
How are motors on a serial bus controlled and synchronised?
My only real control experience is with LinuxCNC with Mesa and parallel port
hardware where commands and feedback and precisely timed. Sending commands and

6 line walls/perimeters is a large number. My default setting is 2. Less
perimeters also prints a lot faster. If the part is weak, you can always
increase it later, but it

I just checked the 2.7 & 2.8 versions documentation, and they have the same
description as teh 2.9 version.
