General Mach Discussion / Re: Can load Gcode panel put newest file first, by default?

It wont happen i'm afraid.

No work is being done on Mach3 any more, it was shelved some time ago.

It is what it is from now on.

LOL, see what you mean

I tend to keep my working files on a USB stick, only the files for the jobs I'm on. Once finished they get deleted or moved to storage.

This keeps the jobs folder pretty empty.

A custom dialogue box would solve it but thats not going to happen.

Yes,

in the file-open dialogue, click the top right hand button "view options"
select "Details"
click on the date column header

this will sort ascending or descending each click

General Mach Discussion / Re: Homing and Limits

Not sure what machine this is on but on my bridgeport mill, the hard limits are wired into the safety circuit NOT mach3, if it hits a hard limit it cuts all power to the axis drives so the ONLY way out is the reach for a spanner and screw the axis off by hand.

This was a safety setup decision - it has servo motors and in the event of a runaway drive it would smash the end off the machine in a flash so a very hard limit was thought safest.

The soft limits are the main operation limit system.

I thought spindle calibrate only had an effect if there was encoder feedback of the actual spindle speed i.e Mach3 was controlling the Pid loop???

My money would be on hardware

Easier to debug too.

Ah, I see - yes i had the same issue and just wound the screw off the stop by hand a few times. Once soft limits are set properly, the issue never occurs again, my soft limits are set 3mm off the hard limits IIRC.

You would think that as Mach knew which way the axis was moving when it hit the limit, it would simply allow movement in the opposite direction, but i Mach is what it is, end of.

What it is, is really a pretty good way of building CNC machinery, there are other options out there now but i have no idea if they are better, the same or worse than Mach3.

I don't know about Mach4 but once setup and working, limits with soft-limits in Mach3 is pretty bullet proof, I have three machines here all setup the same and all work just fine - I can jog into any soft-limit and it still allows me to jog off ok.

It must be a setting or construction/wiring issue.

Make sure to kill the screen-saver too if any

Ok thanks for the update
