Easily change many Motion Profiles at once, by sending a text file, instead of typing each individually--very handy!

Many Excitron rotary tables can have a gear ratio of 90:1, 486:1, and 628:1. After you physically mount the motor in the gear ratio position you want, you will want to change the Joysticks. You can do this quickly and easily, without errors, by sending a text file. 3 examples are given here for our rotary table.

Your serial program, like Realterm, must have a 50msec char delay and 150 msec line delay. These delays could be shorter, but these Motion Profile changes just take a few seconds. No separate Excitron controller command needed, just send your file.  copy/paste one of the following values to a .txt file.  In Realterm, select the Send tab. In lower section, click 3 dots to select your text file. Change Char Delay to 50 msec/char and Line Delay to 150msec. Then click Send. See Serial Programs link for more details.Examples below are recommended for 90:1, 486:1, and 628:1, but you can make these any values you want for linear motion or other gear ratios.

first change the gear ratio by the c submenu:

c~
L
0
G00090
G00090
Q

In the above, do the Gear ratio command twice.  The value is 00090, 00486, 00648, or whatever you need.  The L command selcts rotary degrees or linear centimeters.

The N parameters above are set for 1, 5, 30, 45 degrees, and 1 revolution. With these degree values, you can rotate to any angle. For instance, to rotate to 12 degrees, push J1 2 times and J2 2 times, total of 12 degrees. The really nice DRO digital readout will show you the position and degrees as you push each Joystick. There are 2 sections because for 486:1 ratio, usually J1-J5 is CCW AND J6-10 IS CW. You can copy/paste these values to your own text file. CR and LF chars are ok because the Excitron controller ignores them. Do not add any comments, etc., send just as you see above.

The N parameters above are set for 1, 5, 30, 45 degrees, and 1 revolution. There are 2 sections because for 90:1 ratio, usually J1-J5 is CW AND J6-10 IS CCW. Note the direction is reversed, because the 486:1 has an additional spur gear set, which reverses direction. You can copy/paste these values to your own text file.

If you only rotate in one direction, then set the 10 Joysticks to 10 different angles--awesome! Now you can see how easy it is to modify the text file and change other parameters, like time t command, V for steps/second, and others.

Here is an example text file for changing the gear ratio little c command c commands linear leadscrew for linear motion:

c~
L
1
G07313
G07313
Q

This our linear leadscrew ratio for one of our CNC mills. The ratio comes from a 9.33333 spur gear set and a .2008" precision leadscrew, and 400 hsteps / motor rev.
