@laplacek Sorry you received a faulty Duet. It does happen from time to time. Yes, boards are tested before they leave the factory, including the WiFi; there's a full test rig. It does look like there wasn't much solder on the WiFi module. I'd guess that it worked in the factory, but maybe movement or thermals cracked one of the joints on its journey around the world.

Let me know if you have any further problems. We will leave the option of a warranty replacement open.

@downshift64 said in duet 2 wifi setting up BLtouch:

@fcwilt can you use a z stop switch and a bltouch i would like to home my cartesian printer at the top of Z and use the bltouch also

Certainly.

All of my printers had Z probes and all of my printers have Z endstops at the low (min) end of the the axis.

Homing with a Z endstop can result in simpler and quicker code.

You can, if needs be, have two endstop switches, one at the low end for homing, one at the high end for resuming a print.

Of course you need to have routines to change the configuration of the M574 for the Z endstop, since it can only handle one at a time.

@buurman

There is a video out there showing that microswitches are actually very, very good when it comes to repeatability.

They are simple, safe and if you don't use the plain kind (not circuit board) they only need 2 wires. If you go the route be sure to the the COM and NC connections.

The kind with the circuit board have a couple of advantages (usually). They provide an LED to verify state. The signal is actively pulled-down or pulled-up so the signal wire to the Duet is never dealing with an open circuit which can act like an antenna pickup up noise.

There may be kinds a circuit board that don't behave that way but all the ones I have used do.

@droftarts Thanks very much. That sorted it.

@phaedrux would I use M591 D0 S1 to enable and M591 D0 S0 to disable and would I need to change S1 to SO disable them in config.g?

Shouldn't it be disabled in tfree rather then tpost?

I haven't used these before so I'm tryting to figure it out now. I should have a tfree, tpre and tpost file for each tool correct? I am using a single nozzle with 4 extruders.

Here is what I have for my tfree0.g, tfree1.g, tfree2.g and

M83 ; relative extruder mode G1 E-150 F300 ; retract 150mm G1 E-300 F2500 ; retract 300mm

for tpre0.g,

M591 D0 S1

tpre1.g

M591 D1 S1

tpre2.g

M591 D2 S1

tfree3.g

M591 D3 S1

For tpost0.g, tpost1.g, tpost2.g and tpost3.g

M116 P0 ; wait for tool 0 only to reach operating temperature M83 ; relative extruder mode G1 E450 F2500 ; undo retraction

Does this look OK?

Do I need to include a tool change script in my slicer (simplify 3d) to run the macros?

Sorry for all of the questions. Thanks

@gnydick said in Heater Cartridge Safety Questions:

@deckingman nice! Did you machine the 6 chamber hotend? Videos, cad files?

Yes I did - I documented my journey on my YouTube channel - link is in my signature.

@worekarolis that mosfet is not suitable.

@joeko

Thanks for the explanation.

@signpostman

I haven't read this entire thread so I don't know what you mean by "Is there any other way to connect my ClearPath Servos to the Duet 3 main board?"

If you have specific questions, you should probably start a new thread with those questions and I'd be happy to help.

@mac Yes, of course I watched the video! That's what I was commenting on.

the home point for this Xvico was the FRONT, LEFT, Corner

Sorry, but I'd say the nozzle in the image below is over the back right corner, viewed from the front of the machine (ie reading the text on the bed the correct way up, left to right). If you've set the endstops up as maximum endstops (ie bed maximum position is set when homed, like X200 Y200), then fine, but if they're set up as minimum endstops, the machine coordinates are rotated 180 degrees. Just for clarity: the X axis is (usually) the one that has the nozzle on it (goes left/right), the Y axis is the bed (goes forward/backward).

I copied the M569 commands from the config.g you posted a few days ago. I probably should have said to check the 'S' parameter in them (that's the axis direction)! It's the D3 that silences the motors. It should not have made the motors move, or done anything to the fan. I thought the squealing was motor coil whine, not the fan! Because it stopped when you moved an axis. If it helps, add it to the M569 commands in config.g. Maybe post your current config.g in this thread, too.

Why is homing the x-axis telling the z-axis to go up and then down?

Because homex.g tells it to. Usually it's best to lift the nozzle before homing, just in case it has stopped on the bed, or stopped during printing, so it stops the nozzle being dragged along the bed. Lifting it 5mm is normal, and it usually drops it again after the X (and Y does the same thing) has been homed.

Ian

@phaedrux Yes, I think I've read quite a few of them at this point.

I sent you a video link. If you've got 40 seconds, I hope you'll watch it.

@tinchus said in "semaphore" control:

@fcwilt but as I said, I connected the ground PIN too. There is something Im not understanding?

The out6 pin, when "on" connects to GND.

If you have an lamp of some sort connected between out6 and GND then both ends of the lamp get connected to GND - that is not going to work.

The "negative" end of the lamp needs to connect to out6 and the "positive" end of the lamp needs to connect to V_OUTLC1

@nightowl Droftarts asked me to post my config.g and Homez.g files because my X and Z motors are locking up. He’s trying to help me figure out what’s going on with this conversion.

@nightowl I created a new config and homex for an Ender 3 with my board in it. From a config and a related article about putting a Duet 3D Mini 5+ in a real Ender 3. What I posted is gone.

@fcwilt
One more note, I swapped the ports for tools 3 and 4, and now all the tools work again. I think there's something wonky with the tool distribution board, so I'm ordering a replacement.

Thanks,
Steve

@mac Your second video has the BLTouch working correctly; at startup it does 2 self test deploy and retracts, then stays lit up in red. It is supposed to be powered from 5V. That's what the wiring table says to do.

If you look at the BLTouch documentation, you'll see the BLTouch can OUTPUT 5V, or can be set to OUTPUT 3.3V. On old Duet 2 boards, if you set it to output 5V, the input on the Duet can't cope with that voltage, so you have to set the BLTouch to output 3.3V. It's not relevant any more. It is explained in the Duet 2 section of the documentation. The Duet 3 section has the note that says it doesn't matter.

As for the motors and the screen, please post your config.g and homex.g files.

Ian

@droftarts Thanks for the reply, and you helped me figure this out. I turned MS3 to off and EN to low. It's working now. Appreciate the help!

@rushmere3d took me a minute, but I see it now. We’re a ways away from that.
