Until now I have done many fine things with "old Mac3".... And I will keep doing...

Excellent

General Mach Discussion / Re: Turning on the relay causes a 'limit switch triggered' error

« on: March 09, 2019, 10:01:21 AM »

I put in a value of 1000 and with that the relay would trigger properly and the job would start as well. However, I have started getting random failures with a 'Limit switch triggered' message. I then increased it to a value of 6250 (the equivalent of 250ms). With this, it still randomly stops but there is a significant delay now before the job fails - still randomly. The stepper wires are shielded but not the limit switches and the estop.

This confirms that it is indeed electrical noise and you now need to check your wiring layout to see where improvements can be made.

I think you have already identified the problem...
All inputs (limit switches, EStop, etc) should be connected with twin shielded cable (with the shield connected to a single point Earth at the controller end only). If you do this then you should be able to reduce the debounce value to a sensible value of about 500.

Sounds very much like electrical 'noise'.

Try increasing the Debounce Interval (Config. / General Config.) to around 1000 and see if that makes any difference.

Hi Stefanus,

Welcome to the forum.

Just a general note to all...
It would be helpful if images were re-sized to 800 x 600 before posting to the forum. This thread relates;  https://www.machsupport.com/forum/index.php?topic=24585.0

Mach3 under Vista / Re: Win7 32 bits Mach3 with parallel port pulsing at 100K

« on: March 02, 2019, 04:52:30 AM »

(I intend to dual boot Win7 32bits and win 10 64bits)

By all means try but you will not be able to use the LPT Parallel Port on a 64 bit PC.

Hi Chuck2302,

Welcome.

Could you also post your question on the Warp9 forum here; https://www.warp9td.com/index.php/kunena/7-general-discussion  (Andy will be able to give you detailed instruction on how to resolve the problem).

Show"N"Tell ( Your Machines) / Re: The Laser Project.

« on: February 25, 2019, 07:16:37 AM »

I have just been contacted by a Mach3 user in The Netherlands who does not like to post here because he says that he does not have good English. Well:  Zijn Engels is een stuk beter dan mijn Nederlands.

He uses a Chinese motion controller which will output spindle PWM but it does not support the M11/M10 command set and up till now he has just been using an imaginary Axis Direction pin to switch his laser ON/OFF and controlling output power manually.
He has now tried the gating concept shown in post #1067 and he discovered it has an unexpected benefit…

For a while, a few years back when the M11/M10 command set was broken, I used the B axis direction pin to switch my laser ON/OFF – although this worked just fine EStop would not automatically turn the laser OFF and this really did represent a fire hazard.
Because Mach3 allows all Outputs to be switched OFF upon EStop (and this includes the PWM signal) gating an Axis Direction signal with PWM will always switch the laser OFF when an M5 or M30 or EStop is encountered. Brilliant.

This is something I had not considered – thanks Joost for the heads-up on this one (we never stop learning).

Assuming that you have not lost it then it is in your Mach3 folder and it is called Mach1Lic.dat
