Mach4 General Discussion / Re: Mach4 engraving CNC laser machine missing steps and regaining them ...?

« on: July 22, 2018, 08:14:24 AM »

I do use a 57CNC for laser work but not with Mach4 so I do not know if the 57CNC actually supports the M62/M63 commands. May I suggest that you contact PoLabs to check this before proceeding;   http://support.polabs.com/

Your Gcode looks fine, which motion controller are you using ?

Mach3 and G-Rex / Re: Cant get parallel port working

Perhaps a second user PC, which are cheap enough, but check that the parallel port is 5 Volt. You could, if necessary, fit a 5 Volt PCI Parallel Port card - check here for details; http://www.machsupport.com/forum/index.php/topic,34848.msg239910.html#msg239910

Alternately why not consider an external motion controller that could be used with your laptop - many to choose from but best to avoid those from China. (I currently use an ESS on one machine and a 57CNC on another).

VB and the development of wizards / Re: Quick bit of advice please. Want to write wizards and know - nothing much!

The programming language is strictly speaking Cypress Enable ( a subset of Microsoft VB ) it is easy to learn but it is useless at error reporting so there are many little secrets to getting it all to run correctly. Perhaps that makes the learning fun (perhaps not).

There is so much information with working examples you could perhaps check out the following…

The 'P' defines the Output# so M62P1 would turn on Output#1 and M63P1 would turn off Output #1 but only at the instant of following axis (any axis) movement.

At the moment you have the Z axis direction pin set as your laser trigger, change your setup so that Output#1 is your laser trigger then the M62P1 / M63P1 commands will switch your laser.

I have already seen this in the Gcode file (the missing letters), and other Gcode files with text in them,  why does aspire calculates it in this way, or is it the postprocessor ...?

Who knows, the way in which Aspire creates it's toolpath is a mystery to me.

why is the M62 M63 an advantage ? 

Those commands have been specially created for laser use, taking effect at the instant of axis movement, and performing a better job with Mach4 than an axis direction pin.

I will look into you postprocessor

My post processor was just for inserting the M62/M63 commands it will not create a different toolpath or workflow.

I only ran a small portion of your Gcode and it is not good.

Your Gcode consists of too many short segment moves and missed letters (which are returned to later in the Gcode for completion of the word). If you did, for any reason, miss a step or two this could explain the transposed letters.

I think that if you improved your Gcode compilation you would not be having this problem.

You may also want to look at using the M62/M63 commands for switching the laser Output# rather than the Z axis direction pin. If it's any help to you my Vectric / Mach4 / Laser post processor is here; https://www.machsupport.com/forum/index.php/topic,36640.0.html
