General Mach Discussion / Re: How to use the Run From Here option.

For me it definetly went lower then target :(

I'll check it... However, It would be wise to program this into mach, that if current Z is higher than SAFE z, then do not go to that level...
(E.g. in my case "before" level was +3, target level was +2, and it went down to something lower than +2)

TOmorrow I do some air-tests...

Never messed with it... My guess is no, but I will check it to be sure.
btw. what should it do with safe Z?

I do not know if I am lame, or there is a bug somewhere...

I select a line, click run from here.... then if offers some coordinates for preparation move, but then the the machine does some weird movements... what can be the reason? It is e.g. at Z 2... prep move is for Z 3 *and some x y movements are involved* but then it lowers the Z first DOWN... WHY? I have broken quite some tools already and damaged a few fixtures thinking logically, but seems I miss a point or... ?

Oh, not to mention, if I want a run from here option with a program with subroutines, (G52 shift before each sub call) then things become even more strange...

hm, if I go on a line and click run from here what is mach supposed to do?
I think it should run from beginning to figure out where it has to be, and the selected line is the one to be executed, so it should move to the position of the end of the previous line... no? or something similar at least....

Please give advice.


SmoothStepper USB / Re: Feed hold and SS

Anyone can give advice if the following is SS or MACH issue?

When I run a program with Subroutine, and press feedhold while within a subroutine, and later on I press cycle start to contiune, it executes the rest of the sub, but when it gets to M99 the program halts, with an error message of "return called with no sub in effect... looping"

Why does it forget with feedhold that it was within a subroutine? (I wonder it would be a bigger mess, if there were subroutines called from subroutines)

I am using latest SS plugin, and not the latest mach lockdown, but quite a recent one...

Ok, clearer now, thanks!

Occassionally I have seen on one of the links there that there is G47 for text/serial No. engraving... Mach does not support this for the moment, right? (btw. there is text engraving wizard, which does not give any output)


Maybe I was not checking excessively, but where do I find the list of these variables?
In the MACH user manual only a few are mentioned...
A full chart would be handy, with some explanation. (I have just seen you say 1-33 local var, 100-149 global, etc...)

I want to use them on G-code level, no VB or macro and such for the moment :)

Probing with G31 uses only the variables 2000 for X and 2001 for Y ??? (I reach them with #2000 from within the Gcode program, right?)

What about Z?

General Mach Discussion / Re: Viewing Parameters

I am not a big Gcode expert, but I am trying to put together a small program within the Gcode file...

For this I need to know how to store POSITION value of an axis to a parameter.

What I have found in the manual is that I can use parameter value as a coordiante (so computer puts the actual value of the parameter to the given axis position) but I just wan the other way around...

this should be possible from gcode, I just do not know how...

I have quickly put together the math for what i want, but I have this obstacle now...
I want to probe a few points, then record the probed coordiantes, make some calculations (add, subtract, divide, multiply, arctan) and then use the results for coordinate shifting and rotation....

Just downloaded it.
Do I need to delete the old one, or just copy/double click this, and it will overwrite the prev. version?

Thanks for the updates :)
