RE: [CAD_CAM_EDM_DRO] CAM Software and Hardware

Mark:

Your computer is somewhat faster than mine, so that's not the problem. Now,
is your "slow" speed slower or at the maximum speed that you specified to
the software?

If you're running at the top speed that you set, then the program is doing
exactly what it should, and you ought to increase the speed.

If you're actually running slower than the maximum speed that you set, then
increasing the maximum speed shouldn't do anything for you. Typically, the
max speed is the speed used for the G00 (uncontrolled path mode. simply move
from where you're at to the new position along any trajectory) G01 and the
other codes use the Feedrate that you specified. You did specify a feed
rate, didn't you? If you haven't specified any feed rate, then the machine
may be working off of an internally set default, which could be slower than
you'd really want.

Set your X carriage in the middle of its travel and start your program,
setting this location as 0. Then enter the mdi mode (execute one G code
block at a time) and type the following:

G01 X2 F2<EnterKey>

does the motor move the carriage to the left two inches?

Now enter another instruction

G01 X0 F5<EnterKey>

does the motor move back to its original location? Does is move somewhat
faster than it did while moving from 0 to 2? If so, let's take the next step

G01 X2 F10<EnterKey>

Continue until you get to a point where either you've reached the max speed,
or the motor stalls.

You'll note that the speed command is F<Value> where Value is the speed you
want in inches per minute (I assume that you're using the Imperial
measurements. I believe that G70/G71 selects either inch or metric) If you
don't specify an F value, you'll find that you're at the mercy of the G-Code
controller designer. And that person may select an "unreasonably" slow value
as a default, or may select no default.

Hope this helps.
