Need help with homing

Post by ajleone11 » Sat Feb 04, 2017 3:43 pm

Just completed assembly of my Shapeoko XXL. Fired it up and was able to jog with no issues. Trying to home it and I get a grbl error. What do I need to do to do the homing?

Also, there are two blinking lights, one red and one green on the circuit board. Are they supposed to be blinking? The green on is just above the blue one and the red is above the green.

Thanks,

Tony

Okay, here's what I get:

power up
left blue light steady on
right blue light blinks on and off

connect
red and green lights blink --- I believe these indicate communication with the board

home
blue light(s)? blink as switches are hit

(I have got to rig up my enclosure so that I can see those lights)

I believe that the problem is that your machine is on one of the switches (move it towards the center of the cutting area), or you have a bad switch.

Test the switches first by powering down, manually triggering them a few times, then trying to power up and home again. If that doesn't help, then try removing all but the Z-axis switch and then try powering up and homing --- if it homes the Z-axis successfully, power down and try again with the X-axis (make sure the carriage is closer to the right side of the machine were the X-axis homing switch is than to the back), then try connecting the Y-axis switch.

I got the machine to start homing but the z-axis just shakes in place and nothing moves

Thanks,

When I hit the start homing button the z-axis pulls all the way to the top and keeps going unless I turn the machine off.

Please try a different switch in the Z-axis connector and trigger it manually --- I suspect you have a bad Z-axis switch --- if that works, then use the machine w/o homing while you contact support@carbide3d.com and we'll get a replacement out to you. If not, then it _might_ be that you have a bad board (but that's not something I've seen before).

OK switched homing cables. Same problem. Turned off homing. Jogged X,Y no issue. Went to jog Z and regardless of + or - the Z is only moving in positive direction until is reaches the top.

Not sure where to go here. Is there any grbl code I need to have in?

Thanks

Let's review:

Did you follow the installation instructions at: http://docs.carbide3d.com/article/67-sh ... stallation

Did you configure not just Grbl, but also Carbide Motion's preferences?

Have you tested all 3 switches in the Z- homing switch connector and manually triggering them doesn't work?

The possibilities as I see it:

- mis-configuration --- you have to have homing enabled in both Grbl and Carbide Motion (if using CM)
- bad board --- not sure how this could happen, but I'm sure it's possible
- three bad homing switches --- this seems pretty far beyond the pale

Hopefully something in the above will help, if not, send a message to support@carbide3d.com and someone who actually understands this stuff will actually help you.

I suspect I have a software issue. I'll go back and review.

One more question. With homing off, I should be able to jog z in both directions but I can't . Any thoughts?

If you can't jog the machine, then the system probably still has homing enabled. Homing first, is a requirement for any sort of movement including jogging.

Please review your defaults against the ones here: http://docs.carbide3d.com/article/38-sh ... l-settings
