Delta with duet-wifi and smart efflector
-
Need some help please with a home made delta I've built. I home all and its all good. Then when I send the command G30 I get this message, Error: Z probe already triggered at start of probing move. Any help would be grateful on what I need to addjust.
Cheers

Might want to post your config.g file to make sure you have all of the setting right.

Most probably a wiring error. Does the green LED on the Smart Effector flash when you power up and then go off? If so then the problem is likely to be in the wire that carries the output signal of the effector to the Z probe IN pin.
-
Thanks for the quick reply, yes the led on the efflector flashes twice when powering on.
-
And I will check the wiring output from the efflector down to the input of the board now and will report back.
-
I just remembered something: are you using a Duet 0.8.5? If so then Z probe mode 5 doesn't work in older firmware revisions.
-
I have the Duet Wifi V1.03, and I have checked all the wiring which looked all fine until I got the multimeter to it to find one bad crimp on the input side by me?and all good now. The other question is as I power the machine up both the hotend and work cooling fans are at full bore until I slide them to 0 on the web controll. Any pointers would be great.
And thank you David for pointing me in the Wright direction for the efflectorCheers

Normal practice is to connect the print cooling fan to the Fan 0 output and the hot end fan to the Fan 1 output. That way, at power up the print cooling fan will stay off; while the hot end fan (and Smart Effector LEDs) will turn on briefly, then go off unless the hot end is hot. This assumes you don't change the fan settings in config.g.
-
Ok plugs changed round fans are good now, the other problem is when I activate the hot end temperature is reading at room temp of 22.6°C, as the hotend starts to warm up the temperature reading comes down instead of going up and get this message,
Error: Heating fault on heater 1, temperature rising much slowly than the expected 1.8°C/sec.
Maybe I'm missing somthing somewhere -
Ok so I'm still stuck with the temperature reading. Setup is as follows,
Duet Wifi with a smart efflector on a Delta.
My question is, I have put the PT100 thermister onto the E3D block and plugged it into the smart efflector, now off the efflector you have the 4 pin outs on the hotend temperature sensor T1, T2, T3, T4, and going onto the efflector behind those pins are two pads labled jumper for two wire, so on for two wire and off for four wire. Labled T1+T2 are paired and T3+T4 are paired. So which paired do I connect from and to where on the Duet Wifi? Also if it help I do have the PT100 board which looks like I can plug it onto the Duet. Which configuration would be more suitable for me, any help would be grateful.Rob

Two choices;
4-wire connection (best): connect pins T1, T2, T3 and T4 to one of the 4-way terminal blocks on the PT100 daughter board in the same order (it doesn't matter which end you start from). Remove the jumpers from the two pairs of jumper pins on that channel of the daughter board.
2-wire connection: connect T2 and T3 to the middle 2 pins of the 4-way terminal block on the PT100 daughter board. Fit jumpers on both pairs of jumper pins on that daughter board channel.
See the wiki for how to configure PT100 sensors in firmware.
