General Mach Discussion / Help! Spindle OFF Intermittently Trip Limit Switch

« on: June 10, 2008, 08:34:40 PM »

Hi All,

My converted Series I Bridgeport intermittently trip the limit switch.  It happens about 5% off the time.
I look at the diagnostic screen but did not see the LED change state.  So it must be something transient.

How would I troubleshoot and eliminate this problem.

Thanks!

General Mach Discussion / 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
eg1.
G90 G64
 M6  T1 (TOOL CHANGE center_5) (MSG, LOAD TOOL # 1)
G0 G54 X0.4927 Y-0.5938
M03 S978

eg2.
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.


Thanks.

General Mach Discussion / Mach control wrong axis intermittently

« on: March 14, 2008, 07:16:52 AM »

Recently, my Syil SX3 CNC is doing weird thing.

Symptoms include:
1. lack of control on some to all axis at one time.
2. swap control of x-axis & a-axis
3. doubling or half speed (DRO read 2" move while actual is 1" and vv.)

During the time when this happens MACH DRO increase value when I jog but the stepper does not send out any pulse.

I'm not sure if this is a problem with my parallel port interface board or MACH but the solution is to shut down MACH and restart then everything is OK for a while.

Anyone experience this before?  Anyway to pinpoint the problem?
Thanx guys

General Mach Discussion / Change "TAB" Hotkey

« on: March 02, 2008, 05:09:39 PM »

I'm currently running Mach3 with a touchscreen and wireless keypad.  Is there a way to change the default jog key (TAB) to the keypad decimal point (.)?

General Mach Discussion / Help with N-Code

« on: October 14, 2007, 04:52:03 AM »

Hi Guys,

I'm just started using FeatureCAM to generate some NC codes.
I tried running the code on MACH3 but I get the following error.
"Unknown word starting with cLine 54"

What are these N-Code
eg. N280PClamp01M98

Can I just manually delete them and run?
Anyway to stop FeatureCAM from putting these in my G-Codes.

Thanx

General Mach Discussion / Help! Is my controller losing steps?

« on: June 25, 2007, 03:31:08 AM »

I tried to do a 3" OD groove 0.400" deep.
The first piece machine perfectly fine.

When I tried to do the second part.  1/2 way thru the bed (X&Y) stop moving.  It physically sat there for ~ 7 seconds (while DRO changes) then continue on "a different" circular path.

The path in blue is the correct path while the new green path is the bad one that developed after the pause.


PC: IBM ThinkPad T20 / only run Mach3 no viruscan or anything else
Machine: Syil SX3
Material: Cast iron

Could someone help explain my problem and how to potentially resolve it.

Many thanx,
Jonathan
