Mach 3 behaving badly?

[John S]

If you know you are not going to run off the table then switch the soft limits off. They are a pain in the arse as they have to be reset for every job if X0.0 and Y 0.0 changes
If you have limit switches fitted then you don't need soft limits.

They were only put into Mach to satisfy the people who couldn't or didn't want to fit limit switches but wanted piece of mind.

Yeah but no but....

I use them a lot, my stuff is all over the table and I'm often jogging around to get positions etc and run into them a lot. Hitting the limits on my build kills all power to the drives so would not want to do it too often plus it means re-homing etc.

This is a commanded soft limit thats being triggered - seems to be a CS_Labs thing i think - if the code tells it to go somewhere it can't it simply throws an instant "limit switch triggered" error and puts Mach into reset.

Trouble is - WHY is it doing it - it seems it was always the Z axis this time, Z Max, which on my machine should never be more than zero as home is at zero.

I really would not want to run without soft limits IMHO.

Dave You do realise that soft and hard limits are two different things when jogging around are you hitting the soft or hard limits?

[Davek0974]

Soft, if i hit the hard limits all the power goes off on the drives etc - you can certainly tell when that happens :)

What version of Mach3 are you running?
3.042.020 or close to it is what seem to be the least buggy,

That was the last version that Art Fenerty supported, after that it went downhill fast...................
