General Mach Discussion / Re: Spindle stopped during code running

« on: May 12, 2015, 03:35:36 PM »

Hood,
Thanks for the fast reply.
Well, this machine is a simple 3040T with a basic controller that has a spindle variable speed knob and an on/off switch for it.
I don't think that it has an index pulse setup. I cannot control the spindle from Mach (on/off or speed). From the cnc machine to the controller I have a parallel port cable, not separate cables for the servos and spindle.
Is there any way I can test or check if it is possible to control the spindle through Mach ?
If it is indeed "blind", is there anything I can do to prevent the machine running the code when the spindle faults for any reason ?
I asked the seller and he said that the spindle doesn't have any current overload protection but only short circuit protection. He suggested that the variable resistor (for the speed variation) might be faulty.
Thanks again for the time spent to read and assist in any way.
Cheers.

General Mach Discussion / Spindle stopped during code running

« on: May 11, 2015, 12:25:04 PM »

Hi Guys,
I just had a bad experience and really don't know how to handle it:
- The spindle motor stopped while running the code !!!
After resetting the machine the spindle was working ok, like nothing happened, so I assume that the controller has some sort of current overload protection that stops the spindle if overloaded.
I have a small 3040T cnc router with Mach3.
How can I set Mach3 to stop all activity (freeze servos and pause code running) if the spindle stops ?
Thanks for reading this guys and for the ones who will answer....thanks a lot.  
The more detailed answer you time permits...the better

Thank you so much for the fast reply.
I am attaching here the full G-code file.
If you can give me any hint about what I'm doing wrong..

General Mach Discussion / Newbie question

« on: February 12, 2015, 09:02:38 AM »

Hi guys,
Newbie here, just registered.
I just started this hobby, with a small 3axis, Aspire and Mach3.
My question is related to the tool change procedure.
I generated the G-code for a part in Aspire. There are 3 tools used for it.
There is a setting in Aspire about the home position. My home is at x=0, y=0, z=30mm
Well, I was expecting the machine to go with tool #1 at (home)  0,0,30 and wait for me to say "go" after changing to tool #2 and resetting the zero for Z.
What it did was this:  at the end of the roughing with tool #1 , it stopped and went up 10mm. That's it.
Am I missing a step, a setting , something ?
I didn't run the simulation for each step in Aspire; can that do anything wrong to the G-code ?
Thanks for your support guys.
