General Mach Discussion / Re: Limit switch help

It could be a bad wire,bad switch,noise OR a currupt XML file.   Check your Switch circuit in mach3, Press the switch and see IF the proper LED lights up on the diagnostics page. IF it does it it not teh circuit .  IF the light is already lit then it may be the XML file. Reload your  good XML backup file. You do have one right??

It also could be a bad PIN on the board or teh supply cable.


IF it is neither of those then look for noise.

(;-) TP

No lights are lit on the diagnostics page, and I am not sure which switch or where it is to press for the test.
I do not have a backup of the XML, however MDA Precision will , so I have mentioned that to them, and now I have learnt where that is, and what it is.
So this issue like all others is a good learning experience, even though a little frustrating.

A back up of XML,,,,,, arh no, didn't know of such a thing to be honest. I am fairly new, as you may have gathered.

Nothing new in the shop, the lathe is unplugged too.
I have no idea about what is where, but here is a picture of the set up when I take off the back of the control box.  The debounce was set to 20000 from the factory, and in another thread I noticed ''Hood'' had told someone 10000 was too high as well, so 20000 is way over. Having said that, it has up until now worked fine. Also in the diagnostic window shows no faults on anything.

OK, so I know there has been threads on this, I have read them. It didn't help me though, as I tried the easy stuff mentioned but not sure what the rest meant.
My machine is a Wabeco 1410 LF running Mach 3 and MDA Precision supplied the control unit on the machine.
I have never had any issues over the 2 years I have owned it, and it has had very little use. A few times it has stopped and gave a Stepper motor error, but that has happened only a few times and not for the last 6 months.

So currently I can machine nothing, as when I try to run a file, it trips on the Y axis and says ''limit switch triggered'' and the next line says ''E stop requested''    It also does this at start up, and never said that before.
I can jog the machine using the key board without issue and never had this error before at all.   

So in the other threads it has been mentioned ''noise'' can likely be the issue. OK, well I confess I am lost there.
I have checked the debounce settings that were mentioned and mine was extremely high as it is, way higher than suggestions given. I changed it to about 5 different settings anyway and no luck.
So next people are talking about ceramic caps and noise shielding, but I have no idea what is meant by this.
Since it worked fine for 2 years in the same location , surely there must be any easy fix that does not require a degree in electronics?

Help, please

I was following a tutorial on Onecnc, and followed their settings.
I will look at the feed.

I will change it so its RPM, and edit the PP as you mention, and see how it works then.

Thanks

If that is the correct profile then it is not a lathe profile. Reason I can categorically say that is the screenset you are using is Tool Setter 3-4 axis.set.
It is the screenset that defines whether it is a mill or lathe profile, if the screenset is a .set then it is a mill one (plasma etc ) for a lathe the screenset has to have a .lset extension.

Sorry about that.
That should be better

Can you please attach your lathes xml.

With regards G96,  in Mach, it is CSS, it doesnt work correctly  (with G95)  but it does work to a certain extent, ie the spindle speed will increase but the feedrate will stick at a constant feed per min rather than feed per rev as it should.

I am thinking the G96 may be your issue and seeing your xml would let me see more quickly how your lathe is set up rather than having to ask you many questions.

Hood

Sorry, time difference and late shift.
This should be the one

I would suggest that you generate code for what you want to do using one of the lathe wizards and compare that
 code to what you are currently using. You need to have a Mach post processor for that software else you are going to get incorrect code for use by Mach. Fanuc had different and additional gcode as compared to Mach3 Lathe code; IE G28, G96,so have a look at the Mach3 Lathe manual for it's explaination of commands.

A few comments below:

N90 G00 .... a rapid to where?
N100 G28 U0.......see the manual
N110 G28 W0...... see the manual
N120 (OD ROUGH RIGHT 85 DEG .8 TIP)
N140 G99 G96 F0.8 S60......there is no G96 in Mach3

Since your using a subroutine we don't know the initial state of the machine / where your coming from.
Don't  say if you have switches or not but will say you should  touch off properly, set home, and create an offset.

Enjoy the learning experience,

RICH

The mill has switches,  the lathe not.
It sure is a learning experience Rich!  Unfortunately there is no Mach post processor for Onecnc lathe and I was hoping to use one piece of software. 
I will do a search for a Mach 3 lathe manual, and get to reading.
I thought it might be me, just being new, or maybe someone knew of a post processor that worked in place of Mach 3.  Maybe a refresh on the setting home and creating offset might be best

You seem to be feeding at 0.8mm/min so no wonder things are slow!

I see it, and will change that one now. I offset the work piece by 38mm but still does not come back to cut it.
I have edited everything and it seems to be working. Such as line N200 I put in X0 in place of 29.6 and upped the feed. But for a complex part I could not do this, so any ideas why the code is nowhere near the part?
Default post works on the mill.
The above code is what Onecnc came up with to skim a round bar of 29.6mm diameter.

While I am waiting for some input, I have been trying to offset the work piece by 29.6mm, but same result almost. It appears a little closer though.
