Forum suggestions and report forum problems. / "Preview post" not working ?

« on: April 21, 2016, 09:18:29 PM »

Any time i hit the 'Preview' button in a new thread or replying to a post, it just shows "Fetching preview..."
If i use the "Quick Reply" at the bottom of a thread and hit 'Preview' it works fine.

Using Ubuntu, Firefox 45.0.2
Plug-ins...
Adblock Plus enabled/disabled dont make difference.
Ghostlery enabled/disabled dont make difference.

Same with Win7 and Firefox (sorry, dont have win7 firefox version)

Is it just me ?

General Mach Discussion / Re: Proximity Sensors, do they need to drop to zero volts when triggered ?

Thanks for the info guys.

Gonna go the 12v route, have a wall power pack, but gonna try and get a computer power supple from a friend, would be nice to have 12, 5 and 3.5v all in one place in case ever needed.

robertspark, thanks for the time and research. I check out the links, some is alittle over my head right now, but i will go back and read more.

2a) So with that said, if i wanted to wire those three in "series" (more so, wire them so they only take up/use a single I/O pin on the BOB) could i run three to a relay (with resistors) and then have the relay hooked to a single pin (passing 5v through relay, then when one of the switchs triggers it will kill the power to the relay coil) ?

2a) Just tested with two switches again:
Tied all Browns together (powering from 5v L7805 regulator)
Tied all Blues to negative
Tied all Blacks together.

Tested the output of the (tied) Blacks, and when ether switch is triggered it will drop to 0.650, so it looks like i could just do that and use a single I/O, right :-) ?

General Mach Discussion / Proximity Sensors, do they need to drop to zero volts when triggered ?

« on: April 20, 2016, 06:21:59 PM »

Hello all...

Just received the following NPN DC6-36V Proximity Sensors, and im waiting for the following router to be delivered (so i can not test the switchs with the unit).

Right now im playing with the switchs using a bench power supply and they are working with 5v IN but when they are triggered, they only drop to 0.633v, not 0 volts, will this be a problem ?

Testing now with 12v (from bench power supply) to 5v voltage regulator.
Powering switchs with (brown wire) 4.978v from L7805 regulator
Not triggered, output (black wire) = 4.973
Triggered output (black wire) = 0.633



Secondary question(s) :-)

1) Would it make sence to use an exturnal power source (a "wall wart") hooked to a 5v voltage regulater, since the switchs are working at 5v ?
Knowing nothing about the control box (BOB) which comes with this router (aside from its an import), im trying to plan ahead so i have as little problems down the road.

2) Alittle electronic nieveness here...
I plan on using 6 switch, two for each axis.
Again, not knowing what the BOB with this router can do, would it make sence to wire three switchs in series (one per axis for the limits) and the other three by themselves for home (through reading on this board, thats seams pretty commen) to use less I/O pins ?
But... while testing two switchs in series:
5v power to (switch one) brown, then (switch one) black to (switch two) brown, there is a 2.5 voltage drop (so im gonna assume these switchs have some kind of resistors in them).
2a) So with that said, if i wanted to wire those three in "series" (more so, wire them so they only take up/use a single I/O pin on the BOB) could i run three to a relay (with resistors) and then have the relay hooked to a single pin (passing 5v through relay, then when one of the switchs triggers it will kill the power to the relay coil) ?


Thanks for any guidence.

What happens if you where to index and machine 4 sides ?  Will it be a total of 4mm off (from first side to last).

How is your program set up, are the corridents a sub program and you just index and call the sub programs a second time ?

Can you post the program ?

Ive only been playing with the Mach3 software/controller (dont have machine yet) so sorry if this is off base. Couldnt you also do this with pure software, add an IF condition and if Z not equal bla M0 instead of M1 ?

Mach seams pretty cool if you can script like that with a VBS MsgBox and it will cause the machine to sit till further instruction.

Well kharrisonkevin, thats about all the trouble shooting i can offer. I do not know the Mach software (have a back round using/running commercial cnc controls ),  but with the g53 and g28's working the same ("wrong") i would guess its something with how the home position is set up, which is why ive asked if you have run any other gcode programs.

Hopefully with the info you have provided, someone with a Mach background will be able to help you.

When I push the single blk the machine does not move on any line of the gcode

Keep the single block button active like you are.

Then hit the cycle start button. Ever time you hit the cycle start button mach should read one line of your program and stop. Then you will have to hit the cycle start button again to make Mach read the next line.

Is this the first program you have tried to run ?

kharrisonkevin, have you successfully run any other programs (before or after the program you posted) ?
With you saying you have to start at line 6 and you also said the program "misbehaves" at the end, its kind of pointing to the g54 and g53 (work shifts and home).

What happens if you change the beginning to:

Code: [Select]

N01 G20 G40 G49 G91.1
N02 G0
N70 G28 G91 Z0.
N71 G90
(Machine Setup - 1  Facing)
(FACING)
N03 T1 M6
N04 S32 M03
N05 G54
N76 X0. Y0.
N06 G43 H1 Z1.
And change the end to:

Code: [Select]

N63 G28 G91 Z0.
N64 G28 X0. Y0.
Try stepping/running through the program in single block mode and post what happens and at what line number when the machine misbehaves.

General Mach Discussion / Re: Displaying a space between lines in g-code viewing window ?

« on: April 03, 2016, 10:55:06 AM »

Thanks, magicniner: after posting i did just that.
Its a work around, but would be nice to have a blank space... guess its something i will have to get used to (the "clean" spaces are just neater to look at (or maybe im just used to it)).

In the end, i found that the CAM software was passing an empty value to the output function (and that output function is where i added my own line counter) so the line numbers i was coming up with where different then what was being displayed. Adding a len check on the value being passed and only counting if there was really something being passed worked a treat.

Next stage is to copy and print all the Operation numbers and Descriptions at the top of the program as comments , this way it will be easy to see right at the top, then just add the line number of the Operation to "Run From Here" and away we go, no scrolling or scanning, just click and go :-)
