General Mach Discussion / Re: machine not backing off homing switch

« on: June 22, 2011, 01:26:37 AM »

I tried to set the estop on pin 15 but the machine would not come out of fault mode so I set it back to 10. Since I have all switches in series I only need one input anyway so I rewired it to pin 11 which is the second connector on the breakout bar from the left (I don't have the manual available while writing this so I can't look up what number the input has, should be input 2). This finally let me home the machine. However, next jog I ran into the switch and the limit did not kick in. I went back to the input config and activated x--,y-- and z++ limits all on pin 11. Now the machine homes, stops when it hits a limit switch and the soft limits are setup as well. I guess I am ready to make my first testcut tomorrow :-)

I will try to configure/wire it so the estop and the home switches don't overlap. I will report back if it works. I appreciate your fast responses, thank you!

I tried deactivating the estop in the setup so it doesn't interfere with the home switches which are on the same pin 10 but it still does not back up. I will try to wire it different tonight and see I that helps.
This is the wiring diagram I used (page 6) and the connectors on the drive (page5) http://www.geckodrive.com/images/fck_uploads/G540%20REV4%20MANUAL.pdf

I read about the debounce in a different post and tried it but no result. I do however have the home and estops on pin 10. The wiring is setup as in the gecko g540 manual. I am not at the machine right now but would it fix it if I set the home switches to a different pin than the estop, for example 11, I would wire it to the second input on the g540. Are there any other settings for the machine to automatically backoff when hitting a switch while homing or is that the default?

Hi everyone,
I know I should make an intro post first but it's late at night and I am fighting with the homing of the machine. So just real quick for now:
After working with a Multicam3000 3 axis router with added knife assembly and i-cut system for a few years at work I just finished building my first own machine. Its based on the solsylva plans and has a G540 drive from Gecko and 380oz steppers.

Now for my problem: When trying to ref all home the z axis moves up (which it is supposed to) until it hits the home switch and then the machine shuts off and never even tries to back off the switch. Message: External Estop requested.
I got all 3 axis switches in series on pin 10 and all switches work, according to the diagnostics screen and when I jog into them. In ports and pins all are active and set to active high (red x at active low column). In home/soft limits all are auto zero and x and y are home neg.

I am pretty sure I forgot a setting somewhere but I can't figure it out. I need some advise please

Thanks
Lukas
