Re: Mach 1 Computer was: Capacitors for Geckos when using fuses

Jim:

Well, let's see if I can be any help here....

One thing about TurboCNC is that it needs to run in real-mode. If
you have memory managers running (like EMM386) or the like then
there'll be a negative performance impact. Command prompt safe mode
from Win98 should be about where you want to be environment-wise.
Next rev I'm putting a bit more detail on the startup screen about
this so there should be no surprises.

The Start, Max, and Accel parameters set up the trapezoid velocity
envelope for a move. Good practice is to start with very
conservative (low) values and work up, increasing acceleration
last. Say 100 Hz to start, 1000Hz max, and 500 accel.

Since Turbo is 486 optimized and runs in textmode DOS, I'd say your
1.4 Gig AMD system is probably better suited to Art's program. These
new processors have some slick opcodes like conditional moves and
SIMD that can really crunch numbers - when the software takes
advantage of them.

Anyway, to measure speeds, run successively higher feedrates until
your sense of danger tells you to stop.

Welcome to CNC machining, by the way. This is a fascinating hobby.
