@droftarts Yes!

That did work to get the probe to function!
I just need to setup the z probe routine for bed leveling.

I am running into a different error, trying to have multiple z axis motors.
Only one of them is functioning. Driver 2 with a jumper on the ZB segment.
Then trying to pair the driver 6 and 7 to the Z axis.

Is this correct? When I jog after M564 H0, I only have one drive moving.

; Smart Drivers
M569 P0 S0 ;D1 ; driver 0 goes forwards (X axis)
M569 P1 S1 ;D2 ; driver 1 goes forwards (Y axis)
M569 P2 S1 ;D2 ; driver 2 goes forwards (Z axis)
M569 P3 S1 ;D2
M569 P6 S1 ;D2 ; driver 3 goes forwards (extruder 0)
M569 P7 S1 ;D2 ; driver 3 goes forwards (extruder 0)

@dc42 Thank you for the info!

I will try that first.

Thank you

@djthuma Bed heaters are happy to generate heat from AC power, allowing you to use a smaller, cheaper, quieter 24V supply for the rest of the printer. Power to a line-powered bed heater is switched using an SSR connected to the heater pins on the Duet board.

If you already have the 24V heater and power supply, insulating the underside of the bed may allow the low powered heater to eventually get it up to print temperature, but will also extend its cool-down time.

@djthuma 400W is somewhat under-powered for that size bed, especially if it uses a thick aluminium plate. I would use an AC mains voltage bed heater for that size bed. My rule of thumb for heater power is 0.4W per square cm.

The trick to getting slow bed heaters to pass tuning is to use M307 to set a large dead time for that heater before tuning. Try D60.

@T3P3Tony
I think I figured it out!

I was changing the M307 setup in the config.g file.

But I forgot that the config override contained heater settings aswell. So those would eliminate the correct tuning of the config file.

I have updated the config override and it is remaining stable at printing temp.

Thanks, still learning, again 🙂

@T3P3Tony I have them uploaded. But I know they are not functioning properly for the endstop I want to use.

How would you write a probe macro for this situation?

Sorry, I don't have that much experience working with the reprap language for duet.

D'oh!

Easy mistake to make. Ask me how I know.

@djthuma Can you give more information about the setup of your CNC?

The G1 H3 is meant to move to the top most limit switch on the z axis if your Z is higher you can adjust it to make sure you trigger it. This is assuming you have a top limit switch. This is simply meant to do a safe move on my machine that has a top limit of 90mm.

You can see more info on the G1 H param or you could omit it like you have but you will want to make sure that the machine moves in a safe manner when going to your work zero position.

@djthuma said in Duet 6XD motor and endstop connection:

Do I need to split the y motors?

Only if you need to move them independently.

Thank you @Phaedrux

It was my duet 3 and duet 2 's default gateway that was not set to the network gateway!

Not sure if the windows command should be included in the getting connected section.

But I did need to use Command Prompt -> ipconfig/all command to identify the correct network subnet and default gateway.

Thanks again

@dc42
I was able to get a port that connected and YAT got past the error.
I have connected, changed the gateway and subnet.
I was able to access the duet panel controls.
So this aspect of my projects I can say is solved!

Thank you very much!

That solution also assumes the endstops are moveable so that they can be positioned to eliminated any skew. If you can't move them, then you would need to split the X axis into two independent axis, home them, and them apply a movement offset to cure any skew, and then recombine to X.

Both methods are shown here: https://docs.duet3d.com/en/User_manual/Connecting_hardware/Z_probe_auto_levelling

It focuses on the Z axis, but the concept is the same for other axis.

Once you've moved to the exact X, Y and Z starting point of the cut (depending on how you've set this up in the project software - Vectric, Fusion, etc. - and the thickness of the material), clicking the Set Work XYZ in CNC mode.

@djthuma said in Add additional pin output for switch control:

@deckingman

I see the M950 command. But how should it be formatted?

I was using pin 62 to activate the switch.
If i have the M950 command in the config file written like this.
M950 P62 C"spi.cs7"
(is that correct, would that configure pin 62?)

Then a macro file that activated the switch when triggered.

M300 S1222 P444;
M42 P62 S.5

This is how I have it this minute, and it is not correctly working. I am getting an error ( Error:in file macro line 5: M42: 'P' too high )

thanks for the help so far

Read the documentation some more https://docs.duet3d.com/User_manual/Reference/Gcodes#m42-switch-io-pin

Once you have created the GPIO port using M950, you then refer to that port using M42 - not the pin number.

@oliof said in Unable to extrude or retract:

@djthuma Just add T0 at the very end of config.g and you should be all set. It might be a sensible default for a multi head setup as well.

Just to add that if the OP does use multiple tools then T0 P0 would be a better command to use at the end of config.g. The P0 will suppress any tool change macros which might otherwise run whenever power is first applied.

What does YAT report when you connect?

If there is no firmware installed it won't respond to anything because it has no brain to recognize commands.

What does it show up as in device manager?

Does it show up as a Bossa port?

Did you try the Bossa firmware flash steps? That would be my next recommendation.

I see, so you are inserting the relay into the AC input for the bed heater controller and just want to be able to turn it on and off?

What M950 and M42 command are you using?

@o_lampe @djthuma

You can define multiple z probes in RRF and then each probe can have its own retract and deploy

https://duet3d.dozuki.com/Wiki/M401

however @djthuma AFAIR you are running RRF 2.05.1? to do multiple probe deploy and retract macros you will need to move to RRF3.

The core issues here is if you cant level those BL touches or accurately measure their offset relative to the ideal flat plane then using multipl probes to level a bed will have built in errors

@t3p3tony
Yes!
I can still select to print a single item with the primary or secondary extruder.
And its a much less expensive adaptation than buying an entire printer for idex, and not having all of the bugs that a "new" idex type of system has currently.
