Help with spindle speed command.
« on: March 18, 2008, 05:15:31 AM »
Hi guys,

I recently got my spindle to start running.  I'm running into some trouble which I can't seems to understand.

1) Mach3 doesn't seems to like my M-code
G90 G64
 M6  T1 (TOOL CHANGE center_5) (MSG, LOAD TOOL # 1)
G0 G54 X0.4927 Y-0.5938
M03 S978

G0 Z0.1
 G54 X1.362 Y-1.35 S769 

It will always bark at any of the lines with "S" in it.

2. If I set my pulley1 for 200-3500 is there any reason why max limit error occur @ 2500 RPM and limit out at 2500 RPM.

3. If I only have one pulley between my motor and spindle (Syil SX3) where my typical "manual" speed range is 200-3500 RPM, what should I set my pulleys 1-4 and is there anything else this newbie should set.

If you look at the settings page you will see the pulley number in use, it is the correct one?

Graham, I did read through section 5.5.6 Spindle motor setup several times that's why I set my pulley #1 to 200-3500 with a 1:1 ratio.
The reason why I asked the redundant question#3 is because when I was second guessing myself.

Anythow, I think the issue of limit error is a "User Error", most likely I didn't save the settings prior to proceeding.  I went back and change pulley 1-4 to have the same settings 200-3500 with a 1:1 ratio then select pulley #1 and save and so far I don't get the error of max limit.

The other part of question #2 is probably the problem with Syil spindle control board.  I see in the other forums that a few ppls report them being off.

That still leave question #1 open.
