Re: Mach 3 behaving badly?
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.
Re: Mach 3 behaving badly?
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.
Re: Mach 3 behaving badly?
Dave You do realise that soft and hard limits are two different things when jogging around are you hitting the soft or hard limits?
Re: Mach 3 behaving badly?
Soft, if i hit the hard limits all the power goes off on the drives etc - you can certainly tell when that happens :)
Re: Mach 3 behaving badly?
What version of Mach3 are you running?
3.042.020 or close to it is what seem to be the least buggy,

Re: Mach 3 behaving badly?
That was the last version that Art Fenerty supported, after that it went downhill fast...................
Re: Mach 3 behaving badly?
This was the last one i installed...
Mach3Version3.043.062
Re: Mach 3 behaving badly?
I think it is a must to install latest version, especially if you use third party plugins, which typically are made for latest version. Except if plugin maker expressly says what version of mach3 is made for. You should not use tool length offsets at all, especially with the plugins that do probing.
Welcome to Mach3
Re: Mach 3 behaving badly?
This is where we have problems -
Most forum admins and long term supporters of Mach3 admit that many things are broken in new version of Mach3 and will never be fixed. I was strongly advised to use that version by a respected admin.
CS-LAbs do not seem to have any preference at all, at least none is mentioned.
Yes probing with a TLO in play is seriously bad news - i discovered that one by myself when i wrecked my Z-axis. I have blocked all probing from running unless tool zero is selected.
Its more welcome to the bad side of Mach3 - I have used it for a couple of years now on my plasma cutter but that has parallel port connection - Mach was built for this.
I have it on my Mini-Mill and it works ok - that is USB connection but does suffer occasionally from the "Script compile error in M3.m1s" bug which is widely known on the 'net.
This is the first install with ethernet control and servo motors and seems to be being a bit naughty.
