"Z" axis problems CNC
-
Yes, the Z axis should go up and trip the relay but instead just grinds and slowly moves down toward the bed. I will try to send more info.

Please copy and paste the text instead of screenshots.
you can also use the code formatting to make it more readable

Sorry but I'm not sure I understand what you mean by text.

@onescentpro said in "Z" axis problems CNC:
M569 P2 S1 ; physical drive 2 goes forwards
M569 P3 S1 ; physical drive 3 goes forwards
M584 X0 Y1 Z2 E3 ; set drive mappingI take it you're using stepper motors with the built in drivers and not servo motors?
If z is going the wrong way the simple explanation is perhaps to have plugged it the wrong way around (although if using the supplied connectors that's not something you do by accident)
if you've tried another motor and another board then you're left with the wiring, one of the conductors coming loose sounds like it could be a good fit, but the duet normally alerts to a disconnected phase.
-
@onescentpro might be a result of the issue rather than the cause, but given your screenshot show an error message 'Z probe already triggered at start of homing move' I'd start there. What type of probe are you using? What value does the probe show in DWC normally/when you tap it by hand?
Maybe try using the R parameter in your M558 so there is a pause for it to settle?
https://duet3d.dozuki.com/Wiki/Gcode#Section_M558_Set_Z_probe_typeI'd also double check the wiring to it
RE Bearer's posting comment, there is a formatting option on the forum when putting your coding which puts it in nice boxes etc to make it easier to read (like the line of text he put). The option is two over from bullet points at the top (you can see in his screenshot).

@bearer , Good morning, I saw and old post from you that mentioned you could log into my computer and take a look. Is that a possibility for you?
-
@engikeneer Thanks for the reply. I am using the endstops supplied by Ooznest. I have checked the wiring to the stepper motor and its fine. The endstop appears to working fine when I manually close it the light comes on on the Duet so I think it's fine.
-
@bearer I am using everything that was supplied for the Workbee from Ooznest. Yes, I am using steppers controlled by the Duet

So no Z probe at all?
Your config.g and homing files are setup as if you had a Z probe. Please let me know if that is the case or not.

Thanks for all the input. I got everything up and running. So thanks to all who helped me with this problem.
