Limit switch issues

[Pbaustert (Paul baustert)]

I just completed the assembly of my XXL. I went to initiate machine and it won’t move. The Z axis makes a groaning noise then I get a failure warning.

All LEDs light up on my switches and are recognized in the settings. Any help would be greatly appreciated. After I disconnect the motor I can raise the Z axis manually. Then it will start but once it goes all the way down it fails, if I raise it all the way up and start it fails and says it can not find the switch. At a loss.

Most likely you need to send the machine configuration:

Setting Grbl Configuration in CM 517 and later

Carbide Motion 517 uses a new system for setting Travel Dimensions which is potentially confusing: [image] Pressing the Load Defaults button takes one to a window which allows one to select first machine size: [image] and then Z-axis type: [image] after which selection the Travel Dimensions for the selections made are entered into the dialog and will be preserved if one clicks “Ok” (and of course that change discarded if one selects “Cancel”). In addition there is a “Send Configuration…

If that’s not it, contact us at support@carbide3d.com and let us know you’ve seen that link and we’ll do our best to assist.

If you have sent the configuration and you are still failing homing I wrote a doc to help you trouble shoot the proximity switches. The assembly instructions have you mount the switches they may not be triggering. Let me know if the doc helps.
