Re: getting the 57cnc to work with G540

I have not done the spindle code yet. that was the roadrunner file, it just shows you got it correct for the spindle control.

I have worked out the code for a on off button with no direction control (will never need it on my routers) that was easy if statement YaNvrNo and Scott tough me that one in M4.

as you posted.

this will be in a button

if( state)
{ 
    speed = GlobalGet("SpindleSpeed");
    FreeSetSpeed( 8, speed );
}
else
{ FreeSetSpeed( 8,0); 
}

or this just playing on inside computer they both compile ok

//my frequency spindle will use axis 8 step output
global MySpindleAxis = 8;
//axis 8 will be set to constant speed mode
FreeSetAxisMode(MySpindleAxis,1); //set spindle to freq mode

if( state)
{ 
    speed = GlobalGet("SpindleSpeed");
    FreeSetSpeed( 8, speed );
}
else
{ FreeSetSpeed( 8,0); 
}

then as you said this
FreeSetAxisType( 8,1 ); //in the MainScreenInit script

Art I cant get any movement with a G code, I have not turned any scripts on just left as as is from install.

Here is the G code and log the scripter show nothing

Dan:

Because you've used the software before, your scripts are on.  I suspect your failure is because you dont
have a spindle turned on. If the GCode library or call back libraries are on, at least one spindle library must be
on. Also, there was a version early today where the root scripts button didnt properly turn off all scripts.
  Anyway, turn on the GCode lib, and a spindle and see if it runs..

  Watch todays video to see how to see whats failing by turning on the scripter..

i have seen the vid I will try again soon with a spindle control on, and all off.

it works fine in M3

I will test a few ideas and post back

hay Art I have got it down to the spindle control not working, I am going to get it all going through M3 so it gives me the pin numbers, then get it working in Auggie, I am very sure it's the spindle.
I worked it through from nothing ticked, bringing up the scripting window each time, it showed what was need to be turned on or off, I did that and repeated to it got to the spindle control.
using the scripting window to test makes it quite fast.

Dan:

If you turn on a spindle library it should run... relayonly maybe..

I got going the 57CNC or computer needed to be powered down, or pin 17 needed set it was one of these 3 I did all 3

:)

  Next version will have some safeties as Ive added ways for a script to call
a routine name which may or may not yet exist, and do so with no error. This
will keep you from erroring out..

thanks art, it's still a problem with the G540 the other pin does not show up so I may have to do it through the 57CNC only more testing will tale I should have 2 pins active, I only have pin 17 output 1,

Post by **ArtF** » Wed Jan 27, 2016 8:37 am

Hi Dan:

You shouldn't really get any errors in run-time based on what the G540 is doing.. I don't think I'm following
whats happening, yell if you need a hand or it isn't making sense..

Dan
I am trying to following along on the G540 stuff, incase I don't like these chinese drives.
From the way I understand it you are not seeing a signal on pin 17 out of the 57CNC?
What about the pin20 PWM(2) which looks like pin 14 on the Gecko parellel cable?

What were the other two pin numbers you turned on out of curiosity?

Thank you
Glenn

I have a signal on 17 it only came up after I fired up M3 I will turn on pin 20 and see if I am getting anything on pin 14 PWM output in the G540, its a bit of not knowing the corresponding pins, there is 3 things I have to look at it to get the info I need it get's a bit confusing.
I know pin 17 is working it's turning the superpid on from pot to pwm control, its just the PWM output that needs done.

Art the G540 is still unstable with 4 motors turned on, the problem with the net being on is gone, I will test the Ethernet connection soon.

I ran the roadrunner code it started good as it got to half way through the code and crashed, I will run the 2 examples to see if it's more than just random
most times when I home the machine it does not zero out the work concordats.

Art the Ethernet it still run's ruff.
the 2 example file's run fine, that as far as I have got 2 day I will bring up the scripting window and run it again just to see if anything poops up.

Dan:

Homing will not zero the work coordinates, you need to manually do that. Sometimes one would want to, other times one wouldn't.. its nice to see losses before cancelling them out. But in the end a personal homing script could do it for you.

  I'm still stumped on the roughness, I'm beginning to think its CPU speed or graphics speed, I use a pretty good machine. ENet should be the smoothest if that were the case, but I still cant find a spot where that may happen as yet, but I'm sure it will be found eventually.  The weird thing is, Bob find his bad on 3 axis, not 4, and I find mine much smoother on 4, than on 3. Makes sense, the 8 axis engine has 1/2 pulse width..

  More testing I guess, we'll figure it out over time..

homing is fine like that, it does Zero out sometimes by it self 1 in 5 times. I will try my fast machine to see if that helps
