Hi Hood,
Thanks for the quick reply, the switches are micro switches as used on my other machine,
totally forgot about the debounce setting, Dohh!, will try out tomorrow and let you know.
Cheers

General Mach Discussion / Limit switches

« on: February 11, 2011, 03:20:02 PM »

Hi Guys,
I am having a problem wiring up my home switches, I have a Warco round column mill which I converted to CNC
some while ago and wired the switches in series and it works perfectly, I have recently built a 4' x 2' router table
 using the same type of electronics, a DIYCNC Optoport board, Zapp drivers and motors, and wired the switches
in series but when I try to home the machine it homes on Z and backs off the switch as it should then homes on Y
hits the switch and does not back off, it triggers an estop and I cant move off the switch.
I have auto override enabled as on my mill but it wont move even when I use manual override switch, I have to power
down and wind off by hand.
Any Ideas would be greatfully received,
Thanks in advance
Ron

that sometimes causes a problem like you descibe.

Hood
you could be right, it probably only affects the on board port, sorry I hadn't thought of that!

Hi Anthony'
I use Vectric Vcarve Pro, just export the Gcode from Cut2d you don't need to mess with LazyCam.
Perfect results every time, you won't regret buying Cut2d.
Cheers

Hi Shaped,
I just rebooted my computer running Windows 7, actually the OS dosen't matter,
as this is a BIOS setting, I have An American Megatrends BIOS and you need to look through the tabs at
the top of the screen in mine it is listed under the Advanced tab and then under parallel port,
all option are listed there ECP EPP, etc.
Take another look and check all the tabs if your BIOS is different to mine.

Hi Shaped
I am pretty sure that you need to change this setting in the BIOS, which you can access by pressing a key, usually delete, during start up.
Regards

Hi Chip
I finally managed half an hour in the workshop tonight.
The moda .xml wouldn't move the motors, but the debounce setting in the other XML cured the drive off
the limit switches, I have auto limits override selected and so don't need to go to any other screens to drive off, great!
However when the verify button is pressed all axis start to move to home, but as soon as one axis trips its home switch
ALL the axis reverse direction and drive to where they were but because two of the axis have not homed their readings
are meaningless.
Surely all axis should move to home as in a ref all move? It would be really helpfull to get this working to see if I am really
losing steps on the X axis. Is there another way to check this?
Thanks in advance
RonC

Hi Chip
The switches are connected to pin 10, probe to pin 11 & estop to pin 15. Homing works as it should, but when the machine trips a limit I press the reset and drive off the switch, as soon as the switch closes again it triggers an estop I press reset again and drive off OK is this correct? The switches are wired from pin 10 thro' each switch in series and back to ground on the bob.
I have tried using slower feeds but no better.
XML file is enclosed, I hope!!

Not sure what this means
Edit: Is this a Printer Post setup.
Saw your post, Got sidetracked, Chip

In reply to Tweakie the slides seem to be free and they are brand new ball screws.I can move the table by turning the end of the ball screw with my fingers.

Thanks for your time guys, much appreciated
