General Mach Discussion / Re: Soft limits info please...

I like being able to run the gantry around without slamming it into a stop, I guess the z limit is the least important so i could kill it i guess.

Its most useful while im still testing the machine i suppose.

Just noticed the error is on Z-Max which is the upper zero point so the code is sending the head above zero and not too far below.

Apart from disabling Z soft limits, is there a way round this?

All I want to do is have the machine probe Z height before every cut starts, sounds simple but seems not.

I really like the soft limits but if i have to kill the Z one then so be it i guess.

I posted the same issue on Sheetcam forum and got this reply....

"I think the soft limit warning is due to the probing move. During simulation Mach does not know when the probing move will end so it uses the maximum possible move. Each time it probes it moves further down, eventually running into your soft limit.

There isn't really any good solution to this apart from turning off soft limits or disabling probing."

SO second question, is there a way to have the Z axis return to machine zero at the end of a run???

Ok thanks

I will not downgrade until i hear back from you as i really don't like downgrading stuff, it always seems to cause problems.

If there is a better way of doing things then  would rather get it right now before it starts costing me metal wastage etc.

Is there really an issue with probing/offsets in v066??

How can i probe in another way that works??

I was finally hoping to get my machine cutting this week for the first time but I am having serious issues with z soft limits and my code.

Is it easy to downgrade and where do i find older versions? Google brings up nothing.

Will it upset the custom screenset & xml i have?


I'm losing the faith

Oh dear.

How do i get an older version and will it upset the work you did on the screen set???

Could someone have a scan of the simple .tap file attached please.

I am trying to learn why it throws a soft-Z limit upon cycle start.

Z max = 0
Z min = -75
Homed to top position.

I can run the part but not without acknowledging the warning first

thanks

Yes z home is at the top and works ok,

The part i run left z at 10 which is the park setting in the post processor.

I have mach set to issue a g92.1 reset at the end of each run.

the run left the z dro at -95 with a work offset.

When i go to run again i get z soft warning.

If i re-home, all is well but only for one run, i cant run more than one cycle without rehoming???

something is not set right but i fail to see what.

Z max is zero and min is -75 as it homes at the top.

Yeah, thats all done and understood.

I just ran one part, it left the z axis at -95, when i went to repeat the run it faulted on z-axis soft limit.

Z soft is set at -75/0 as that is the physical limits.

I think i'm getting in a state with work offsets or something lingering at the end of each run that i need to reset??

dont forget i'm using G31 probing.
