General Mach Discussion / Re: Single pulse capacitance sensor selection

« on: February 08, 2015, 12:02:58 PM »

Hi,

Thanks for the replies.

I will try the debounce to see if I can get it to see the pulse longer.

I will have a look at redlion and avtron for some solutions.  Prior to seeing these replies, I went out and purchases 2 of these:

From cherry electronics, the selling point for me is that they are 5vdc compatible and marketed as a spindle sensor...

What do you think of these?

Thanks,
Rob

General Mach Discussion / Single pulse capacitance sensor selection

« on: February 05, 2015, 02:44:52 PM »

Spindle sensor 1

Hi,
   As a rookie, I have gone through several selections of single pulse spindle sensors. Optical and fast, inductive capacitance and slow.
     My optical sensor I used along time ago in mach was capable of seeing 20k rpm in mach,but there is the contamination issue.
 I cannot do the optical because contamination, the capacitance sensor I am now using is  slow and only detects upto 600 rpm the. Goes to zero above 600 rpm. What would it take to get mach to see 4000rpm?

The sensor that I am using is an Autonics
pro8-1.5dp
Pnp, normally open, 800hz
http://products.autonicsonline.com/item/proximity-sensors/sors-cylindrical-type-proximity-sensors-pr-serie-2/pr08-1-5dp



I am comfortably using a small 7/8 diameter disk magnet as my trigger and this is about all I can add to this pulley comfortably. So not really desiring to change the pulse, is there something I can do in reselecting the sensor.

How about normally closed sensor?
Would this change the behavior of mach3 to get the pulse detection faster if it were to pull down the voltage to zero when triggered make it faster?

Thanks for your help with this,

Rob

Hi MC and All,

Can anyone tell me exactly what escape key does to mach3?


Thanks for your suggestions. I will review digital I/o in further detail tonight, I didn't see anything obvious on about 10 attempts at getting this condition and watchng the io screen in my early stages of trouble shooting.

Tk has helped me. We went through all of the possible conditions and places to look within kflop/dynomotion's scope. It doesn't happen in kmotion gcode or kmotioncnc at all. There are no key indicators as tom/forum users ran me through some possibilities.

It is specific to and happens in the standard mach3 screenset, brand new profiles, machstandard mill professional profiles
...anything mach related

oem axis inhibit is currently being reviewed, but I am not seeing the led light up. So at this point, that is not looking as a possible root cause but is tbd.

My system is being converted from a smoothstepper to kflop. It has been along time since I have used the ss, but at the time, I did periodically observe something very similiar to this (again, it was along time ago), but I observed conditions where I would have to hit escape/do a software reset. I attributed this to a mach standard mill safety feature and dismissed it as it was subtle. There were never issues running gcode though that I can recall.

I am nearig the point of, at worst,  wiping out my hd and starting over, or  doing a complete uninstall of mach3, kmotion and definitely msm, as I am encountering other very minor issues that are....tolerable.

I'll take a look again at your recommendations when I get back to it tonight.



Thanks
Rob

Hi,
Thanks for your recommendation.
Per your question:....are there any messages displayed in the console?
Only this is displayed:
Movrel0100
Kflop ver#
Ready

Nothing gets displayed in kmotion console during mach3 mdi' entries.

So I have stripped down my init.c program (only leaving my charge pump, and setting bit directions)
This Has had no effect.
Pokeys is not at all the issue as I have had this unplugged for 2 days of testing.
It does still happen, but there is an inconsistency/intermittent that is observed with no pattern or root cause that is entirely repeatable except for the absolute moves which include :

It will error with 100% frequency if:
G0
X1(no error on first move)

Or

G0
X0 (errors)
is entered. Each time I do this, it will be guaranteed that I either have to toggle the software reset, or hit escape key and renter the  command.

Even more weird after testing more: It happens only about ~~20% of the time if I enter numbers other than 0 or 1 such as
G0
X1.3
X1.4
X1.5...(no errors, but will error/not move after some random amount of mdi entries, however it always will error/not move if I enter a 0 or 1 as the absolute distance)

It does happen significantly less frequently in g1, than in g0.
I have to retest this probably a third time (after reboots) and other life delays other than CNC. Thanks for your help and patience to my slow replies.


I'll let you know what happens. Any other thoughts are greatly appreciated.

Thanks
Rob

Hi MC,
Thanks for your reply.
My init thread 1 is green the whole time. It is continually running on a foreverloop. There are no other active threads during this error or an mdi input.
The thread is also pointing in the right direction in the plugin.
The strange thing is that everything works normally in kmotion 'gcode' screen and kmotioncnc and they will accept mutiple commands as normally expected.

I can't get more than 1 mdi command input only in mach3, regardless of, g1,g0, open or closed loop axis, variety of screen-sets.

Is there any ways to monitor what may be happening or why mach3 seems that it can't complete its move.

Does machMAD (maintenance and diagnostics) have any of this ability?
Aside from dumbing down my system, removing a poleys55, these are some of the things I am going to try.

Thanks,
Rob

General Mach Discussion / 1 mdi move only and reset

« on: January 10, 2015, 05:26:29 PM »

Hi,
I am going through a new setup. My kflop is working properly through kmotion cnc, but as I migrate to mach3, I am seeing some issues.
My problem is only one motion command works through mdi (actually moves xy or z). My second entry and any entry thereafter will be ignored.
To get out of this situation, I have to software reset, and then it will accept only 1 mdi move command again. It happens in both g0 or g1.
During this state, if I randomly hit 'zero' as in one of the axis, I get a message 'no zero while running'.

If you have any insight as to why mach3 ?, may be holding onto... Still running... An operation when it has clearly stopped, your insight would be appreciated. How to find out what it is holding onto?running?

Having to reset every mdi command is not happening in kmotion cnc, I have gone through reinstalls, created new profile, and really simplified to find a solution to this.
I am on the most current release of licensed mach3.

Thanks,
Rob
