very slow 3D carving
Posted: Sat Dec 09, 2017 6:18 am
I'm doing a 3D project which is cutting very slowly. I have the cutting speed set to 200 Inches per minute.
There a couple profile cuts where the tool steps out at the specified speed.
It gradually speeds up (the half inch or so) at the beginning of the cut and slows before the end.
However for cuts that involve a lot of Z-Axis movement, the cuts are very slow.
I don't know if it's
(A) the stepper motors that can't keep up, or
(B) the controller can't command the stepper motors fast enough, or
(C) the USB port can't send the compiled G-code fast enough (USB-1?), or
(D) the control panel application can't keep up, or
(E) the cuts are so short that it's always running in the "speeding up" part of the cut.
I'm guessing it's either (C) or (E) that is causing the slowness.
Anyone else experience this? Is there anything I can do to speed things up?
Thanks in advance for your insights.
