Hi, RJ

What type of laser are you using and what Cam SW for your post's, Hears a couple of pic's of my Cut Screen (It's a work in progress screen set), Used it on our water jet cutter and testing stuff hear, with PWM power and the spindle override you should be able to control the power on the fly.

Hoping to work on the laser soon, Who-Now's,

Just trying too Help, Chip

Hi, Generatorlabs

Verify that pin 25 is actually a gnd pin, Not all printer port and cables use all pin's 18-25, I usually jumper pin's 18-25 together at a common point,

The 470 ohm resistor isn't necessary as the input's can be hard grounded.

Try this free printer port program ton test them also. http://www.geekhideout.com/


Hi, RJ

I have a 150 watt Yag laser, Sad to say at this point haven't even fired it UP, This discussion of M3 delay has come up several times quite awhile back.

Spindle speed can still be used with "S" value set in the Post's, 0 or any value you wish, Turned off (0) for rapids, Spindle speed to set power in LC Post {SPEED} for Power during cut's.

PM message your Phone # or do you have Skype phone.

Hears a G code file and a LC post to look at.

Hi, Dan

Make sure your Dir & Step Low Active's are all set the same ether Checked  or X'ed in Motor Outputs, If a axis runs backwards Use Reversed in Home & Limit's to correct this if necessary.

Some axis controls are sensitive to this and cause bizarre result's.

Hi, Generatorlabs

Probably just need to change the Active Low "State" and may need to use the Homes & Limits page to change the Home Direction also.

Hi, Steve

You can have the Home switches anywhere you want them, You just need to insure your on the proper side of them before Homing so they'll be seen when Homing.


Hi, Roger

One piece to your puzzle, Remove the M3,M5's from your Cam Post's and use the Z Direction pin to trigger your Laser on & off, Z- neg. will turn it on and a Z+ pos. will turn it off, This should remove the delay's your experancing.

Hears a LazyCam post with the M3/M5 removed, If you use it with LC's Mill Load you shouldn't have delay's, If you use it with LC's Plasma Load you can have Pierce delays also and a Mill and Plasma G code file.

You'll need to work in a Safe Mode Lockout "Button" to jog around and insure the Z is left in a Z+ pos State, A logic IC that see's the Safe Mode Lockout "Button" state and the Z direction Pin's state to fire the Laser.

Just A Thought, Chip

Hi, Bengt

Re-name your Mach3Mill xml (profile) and post it.

Hears a link to someone Else's post on this, But no fix listed. http://www.machsupport.com/forum/index.php/topic,12232.0.html


Hi, Cuemaker

Post the G code file,

If it was a lic. issue you shouldn't see any scrambled lines, Just nothing displayed after 500 lines of code, I think.

It may be your initial setting's in Mach3 or a Mode change not being set to proper state by your CAM post such as I J's ABS/INC G90.1/G91.1 or ABS/INC G90/G91 after line 500.


Hi, Dave

We can almost hear it running hear.
