BLT on Duet wifi problem

gibsea402

Hi everyone
¨
i have a CoreXY machine with at duet WIfi and a BLT. i cant for the life of me get the BLT to work though. it worked before i updated til RRF 3.3. but now not so much. This i my config.g file. Hope anyone can help.

When i run it, it homes on the X and Y, but then comes with this message: G28: Error: failed to enable endstops

I am pretty new to this. hope anyone can help.

EDIT: No, you seem to be able to home x and y as I now read it. so what I wrote is probably not relevant.

If you're running with NC microswitches as endstops (outer pins) and coupling ground to in I think you should have a pullup configured:

M574 X1 S1 P"^xstop"
M574 Y1 S1 P"^ystop"

Now, I use the mini5+ board and if there are any differences I don't know maybe someone can correct me

@gibsea402 sounds like your issue is occurring when you are homing? Please post your homing files (home, homey, homez and homeall) so we can see what's going on

PS, if you use the code snippet feature on the forum, it makes your code files easier for people to read. It's the </> button at the top (near bold/italic).

Phaedrux

Did you update your deploy and retract macros? Please post those.
Also test if M401 and M402 work to deploy and retract the pin.

And for good measure include the results of sending M122 and M98 P"config.g"

Here is the home all. Thanks for the tip on the code mode.

@gibsea402 This is the section of your homeall that you want to change

G1 H1 Z-395 F360        ; move Z down stopping at the endstop
G90                     ; absolute positioning
G92 Z0                  ; set Z position to axis minimum (you may want to adjust this)

It is using a G1 H1 homing move for Z (i.e. using an endstop which you don't have!), rather than a probing move using the BLTouch. For this you would want to use a G30 probing move (https://duet3d.dozuki.com/Wiki/G30)

So, I would suggest replacing those three lines of code with:

G90    ; set absolute positioning
G1 X150 Y150 F1800   ; move quickly to bed centre - May need to change the X/Y values to suit your printer size
G30  ; probe with BLTouch

You'll see that these commands are in @Arnold_R_Clark's homeall file (though he also has a bunch of extra stuff which may confuse things).

Hi here is the following. I think the issue is that the macro is not updated. But i am not sure how to do that.

Pin down: M280 P3 S10 I1
Pin Up: M280 P3 S90 I1 ; retract BLTouch

If i click on the macros in the web browser they do not work. But if i send the commands M401 and M402 they work.

This seem to work. But if i just give the g30 command the probe is not deploying.

Which macros exactly are you clicking on? M401 and M402 call the deployprobe.g and retractprobe.g files in the /sys folder

Pin down: M280 P3 S10 I1
Pin Up: M280 P3 S90 I1 ; retract BLTouch

Those are incorrect for RRF3. Remove the I1 and instead of P3 you'd use P0 since you are using servo pin 0

M950 S0 C"exp.heater3" ; create servo pin 0 for BLTouch

One of those fan1 should be fan2

Thanks! this helped alot! its all working now
