@t3p3tony ok i try it 🙂 thx !

@tomasro said in Newly installed Duex5, BLTouch no longer working:

@fcwilt It's connected to PWM1 on the Duex board, but I just found that my White and Orange wires were swapped, so that has it fixed. Thanks for coming to my aid 🙂

Glad to hear it turned out to be a simple fix.

@p8blr your wiring diagram shows that you are already using PNP-style connection.

@nightlonk42 with the sensor assembled you should be able to feel the magnet rotates freely when manually running some filament through (by hand to feel the force). if you make a small dot on the part of the assembly that is visible on the back you can observe if the magnetic assembly is rotating freely.

@patrick_487 you can use the board as normal, it it's just that capacitor that failed.

Looks good!

FYI the Duet 3 Mini includes a connector for a 2-driver expansion board. We included a 5V pin on that connector, so that instead of a 2xTMC2209 daughter board, it would be possible to fit a 2x external driver daughter board.

@martin7404 How did you wire up the super pinda to your toolboard? Are you happy with it? I am considering switching from BL-Touch to superpinda as the BLTouch is often acting up on me and feels not as reliable as magnetic probes

@joeko glad you found the problem!

@pickett I'm glad I could help you!

@th0mpy the additional circuitry on the Mainboard and most expansion boards is to provide the firmware.eith reference voltages to compensate for variations in the analog voltage levels. This leads to more accurate and repeatable temperature readings. The 1XD temp input does not have this so is less accurate than other Duets. That is fine for the application (motor overheating sensor).

Peltier modules are bidirectional.

Can you switch the water flow between heated and cold via valves, and reverse the peltier supply polarity for heating / cooling?

It would save the mass of the second set of peltier modules and allow the one set to be distributed more evenly under the bed.

If you used a second heating channel with an appropriate PTC (rather than the normal NTC) thermistor for the cooling control, the board would read the temperature in reverse and should allow it to drive the cooling control?

The displayed temperature would be wrong, but it should allow regulation?

i suppose i got it.
it is an makerbot switch and it has to be connected as an makerbot switch with all 3 wires

@owend
In our electric cars, we had inverters with huge capacitors. The solution was a pre-charge relay, which (in your case) slowly charges the input caps of the PSUs before it gets passed by the SSR. Not sure if this could be done by only one PS_ON pin, but what is live without challenges 😉

@taconite do you mean a manual button to turn the relay off when it is on, like an override/cutout. You can cut the supply with a button in series on the -'ve side as well.

@t3p3tony I bought those limit switches I linked to here

They are working ok I just had to alter the M574 code for the Endstops by adding ! to the X and Y Stop section and switch the wires around on the connectors to match the Duet2 wiring diagram.

M574 X1 S1 P"!xstop"
M574 Y2 S1 P"!ystop"
M574 Z1 S1 P"zstop"

Thanks for your help appreciate it.

@t3p3tony Thank you for your reply.
Thank you for the clear site on C parameters.
I will refer to it.

@tom33 thanks for bearing with the testing. please can you contact warrant@duet3d.com to initiate a warranty return, referencing this forum post.

@jay_s_uk said in Stepper motor juddering after working fine.:

@jderp check your wiring as its probably a loose or damaged cable

I can't believe it was as simple as that. There was indeed a bad connection on one of the wires. 🤦

@dc42 I will. Thank you.
