Mach4 General Discussion / Mach4 seems to lose connection to darwin
« on: June 11, 2015, 06:46:21 AM »
Hi to all,

I have a problem with Mach4 and Darwin- after a random time (5~10 Minutes) Mach4 don't react on any external inputs of my Darwin interface.
I thought that the input script is not longer executed- so then I tried to start a job with the Mach4-Buttons on the screen.
I see the state toggling to "StartCycle" but nothing happens, too.

Some days ago I saw inside a job that Mach4 stops working. No Message, no error -
It stuck in the middle of the G-code. I tried disabling, re-enabling, reset the job- no chance!
The spindle was already running. But no further movements.
A restart of Mach4 solves this state.

I opened the Darwin interface setup- there I can see that Darwin is detecting input changes in the "error state"- but It seems that Mach4 loses the connection or control.
Any Idea? I attached the log when I try to start a job in case that mach4 stuck.

For information: In the error state there are no longer input changes written in the log and no further reaction of the regarding input LEDs in the Mach4 diag screen- only in the darwin setup itself.
For getting the error state I have only to wait - Machine on - working. Then I go for drinking a coffee - when I come back: Machine stuck  :o

Regards and thanks!

Mach4 General Discussion / Mach4 Homing & Darwin Issue
« on: June 10, 2015, 04:27:10 AM »
Hi to all,

Im using Mach4 since two weeks- nice Software with lots of features.  
After looking videos and reading the docs I got the machine running.
Ecept one issue: The homing.
Im using one home switch per axis.

I installed the darwin parallel port Interface and configured the homing switches as input signals.
In the Mach4 settings I redirected the signals to the expected homing Inputs for the three axes.
In the diag screen I see that the homing singnals are working correctly (The "Home-LED" of the regarding Axis toggles).
I don't use limit switches, so I left these setting unconfigured (not available) because I want to use the soft limits.

When I try to home one or all axis the machine state changes to "Homing". And that was it. Nothing happens. No movement.
No error message. I get the control back with emergency stop, so the Software don't freeze.

Is there anyone who knows these bevavior?  ???

Regards from a Mach4User  :)
