Is this the best Halloween costume or what ?

Can you please attach your Gcode that is causing the problem ?

My advice is forget the shed and enjoy a break.

This article gives some insight into laser switching;
http://hobbycncart.com/publ/cikkek/mach3_temaju_cikkek/switching_a_laser_under_mach_control/8-1-0-29

To obtain laser output power control the easiest method I have found is to gate the PWM signal with the Output# used with the M11/M10 (M62/M63) command set and I have described that here;

I await your questions

Assuming you are using Mach3 – are you using the PC’s Parallel Port or are you using an external motion controller ?

I made this video a few years back (before the M62/M63 commands had been added to Mach4) when I gated the PWM with The A axis Direction signal.
The toolpath alternates between Cut and Engrave as the PWM is altered and it serves to illustrate the gating principle I have described.

Hi Johan,

I am not sure you are going about this the right way. A TTL input is digital and only responds to two distinct states – High or Low (excluding the High Z of tri state logic) so connecting it to an analogue output will only produce ON at full power or OFF.

Ideally, to control a laser with adjustable output power you need to gate the digital PWM signal with the M62/M63 commands. This gives laser ON / OFF at the set PWM value.
There are a number of different ways to achieve this but my best (easiest) solution is described in this thread; https://www.machsupport.com/forum/index.php?topic=12444.msg265104#msg265104
(For Mach3, read Mach4 and for M11/M10 read M62/M63)

Hope this helps.

What about the Index Denounce? Both of these Denounce items had values of 1.
Thanks
Kevin Schulz

You need to increase the value;
In Config / General Config see Debounce Interval - set it to 500 and save the changes. Does this solve the problem ?

I agree, just ignore it.

It was probably something added by Andy for debugging a particular problem which has now been resolved.

Which version of the ESS plugin are you using ?
