Mach4 General Discussion / Re: Making MACROS turn on OUTPUTs faster by inlining your code!!

Hi Scott,

Sorry to say this but there is no noticeable increase in speed over the 'multi-liners' (sent to me by Craig last week).

Even slowing the feed-rate down by 1/4 to 1000mm/min this is the result - the gaps represent the 'turn-on' delay and the tails the 'turn-off' delay.

If the Mcodes were gated to an (any) axis movement (as Art did with the M10/M11 set in Mach3) then the situation may be different but I think this needs to be done within the core rather than as an external Mcode.

Damn lasers, you just got to love them really.

EDIT;  Please disregard this post - Now I have had more time to look at this picture, something is not quite right so I may have jumped to the wrong conclusion. I need to re-run the test in order to get more information regarding the 'gaps' and 'tails' in relation to the toolpath.

Thanks Scott it works just fine now  

I don't think Mcodes will ever be fast enough for laser use but now they are working I will give the 'in-liners' a try and report back.

The 34.2 Volts is correct. When rectified and smoothed the dc voltage will be 1.4 times the ac voltage.

Hi Scott,

Agreed, running M770 / M771 in the mcLua editor works but entering M770 or M771 in the MDI or within GCode does not work here.
Obviously I am doing something wrong but so far it has alluded me.

Hi Derrick,

If I am understanding correctly, you are using LPT Pin 7 as your laser trigger.

How is that configured in Mach3 Config / Ports & Pins / Motor Outputs ?

Hi Derrick,

Sorry to hear that you are still having problems with this.

I need more details, could you post (or email me) details of your connections (circuit) perhaps a diagram and pictures. The problem will be something simple but, so far, it is proving illusive to find.

Something's not quite right - they will not turn Output 0  on/off here.

Hi Guys,

I agree with your findings. Although I get smooth machine motion with Mach4 v.1914 and Darwin v1.10 (using my Samsung laptop + parallel port) I would not trust it 100% as I would v.1900. There seems to be a lot more going on in the background with v.1914 and this gives me some cause for concern.
Something I did notice and mentioned in another thread, is that the A axis works OK from MDI but not from GCode.

Best talk to the manufacturer of your transformer to find out how it has been wound.
I would expect to see 24 Volts across the blue / blue but it sounds like you have two 12 Volt windings in parallel (sharing a common start) rather than two 12 Volt windings in series.
