General Mach Discussion / Mach3 Threading and Index Signal Problem
« on: May 24, 2016, 04:51:10 AM »
Hello Everyone,
I did some good things with my Mach3 thanks to your helpful replies around the forum!
But I stuck with index and treading problems.
I almost checked all of the threading posts and index signal posts but still could not figure what is wrong with my system and I would be very appriciate if you guys can help me!
About the system;
I use Leafboy Mach3 Usb Motion Card (AKZ250).
I have a licenced version of Mach3, software is at latest.
I use C3 card for receiving index pulses. (1 slotted disk with approx. 12mm opening.)
Manual spindle control with gear/pako switches. Speed settings can be 33/44/63/110/150/200/.... up to 2000 rpm.
About the program settings;
Kernel speed is 25000Hz
Index signal is enabled on port 11 and "Active Low" unchecked.
"Disable spindle relays" is unchecked.
"Spindle feedback in sync mode" is checked.
"Spindle speed averagging" is unchecked.
I tried every possible setup with Debounce Interval and Index Debounce, no luck. But I am still open to some advice!
Currently Debounce value is 100 and Index value is 10.
The problems are;
I see inconsistent Index pulses from Diagnostic screen for every speed range.
Expect speeds 33rpm and 44rpm, I receive very good RPM feedback. (With 33 and 44rpm, feedback is very unstable and shows 1000-4000rpm movements)
I try to thread the machine with "Simple treading Wizard" but both axis moves to start point and waits for index signal and threading does not start.
I guess index issues are the main problem, but from the LED of both cards (C3 & AKZ250), I see good consistent blinks. Their intervals are exactly the same.
Somewhat Mach3 does not see this blinks correctly.
Hope I made every detail clear.
If I forgot any detail please let me know.
I am waiting your ideas!
Thanks,
Ali
