Hello everyone! i have been using the duet2 wifi for 2 years now on my delta and it works amazing never had any issues, you've done an amazing job both hardware and software wise, i have another laying around so i decided to try and use it for my home built cnc and probably upgrading to duet3 after, the problem is i'm afraid of burning something because i'd like to use a touch probe on my spindle but it is grounded, i'm afraid that by connecting the clip to the endmill it might hurt something on the duet since i'd be connecting the z_probe, 3.3v or GND pin to earth, can you advise on how i should proceed wiring wise ? do i connect the duet ground to the spindle so to earth, or the z_probe in or ..?
thanks a lot !

Hello everyone!
I'm going to replace the wifi module on my duet 2 with an ethernet module I'm using it on a CNC running the cnc version of DWC, since the board is in an industrial electric box that's made from steel I always have to keep it open and facing up to get a decent enough connection for it to be usable and also interference from everything else in the box must not help. I don't have any trouble with soldering as i've done way harder before, but I'm not sure what to do after that, do I have to flash another firmware that's for the ethernet on my duet or do I just change the wifi connection commands and is there anything else I need to change or flash? Thanks a bunch!

@t3p3tony thanks Tony! This seems to be what's happening I'll try it and report back!

hello everyone !
i have 2 duet boards one on a delta and one on a certesian, driver 3 blew on the cartesian, i tried taking unused driver 4 from the delta board and all went well desoldering no shorts etc, but unfortunatly now driver 4 reports short to ground/over temp, and even when i disabling driver 4 with m569 p4 r-1 but that only stops the short/overtemp message, still unable to move with the board saying motor phase A may be disconnected reported by driver(s) 0 1 2 of course i checked the cables with no issues, sooo do i need to solder driver 4 back where it was ? can't the duet function with only 4 drivers ? does it need to be soldered because it's powering the other 4 drivers ? thanks !

@veti thanks a lot ! i saw another post from someone who did it but i didn't see this one thanks !

@phaedrux thank you very much for your reply ! i thought as much but wanted to make sure there is no firmware changes involved ! thanks !

thanks a lot !

thanks for the quick reply ! that's a great idea because it would also work for the super volcano, do you have any idea how i can implement that, for the conditional part ?
may i ask what do you mean by object mode ? thanks !

Hello everyone, i have a quick question, i have two smart effectors one with a v6 and one with a volcano i frequently switch between them, and as you would guess the pid tune differ between the two the v6 tunes cannot hold the tempreture on a volcano so i created two macros one for each tunes, now i was thinking about finding a way on startup or with a macro that can be automatically called at different times before a print or before auto leveling to detect which one of the smart effectors is installed, i have a couple ideas for that and was hoping to have some input to know if they are possible and some help integrating them if they are, now if each smart effector has a different address or id that the duet can read it might be as easy as an "if else statement" (if that is at all possible) and according to the address call the macro with correct tune results. if not maybe a switch or magnetic switch that would only activate on one of the smart effectors and again apply the values, any help would be appreciated as to if this is possible and how.
Thanks a bunch and thank you again for all your work on the duet systems!

Thanks a lot for all your answers it's much clearer now, guess i'll just add beefier steppers ... the only reason i wanted a closed loop system is because i thought that having a closed loop would give me better repeat-ability any advice on how to improve that ?

@dc42 said in Closed loop duet.:

et Ethernet and WiFi configure and monitor the TMC2660 drivers via SPI and use the step and direction inputs to perform movement. Likewise the Maestro uses the UART interface to co

thanks a lot for the info and quick response ! may i ask what do you mean by saying that the built in ramp generator is not suited for 3d printing ? so the duet2 is not using the built in ramp generator on the tmc2660 (if there is one) ?
i'm pretty sure you know better but the tmc2160 doesn't seem to have encoder input.
i'm very excited about the duet 3 i'm pretty sure i'll pick one up soon !
with all that being said do you think a closed loop can still be integrated on the duet 2 with the before mentioned tmc5160 and steppers in external driver mode ? or would it just be a waste of money, effort and time ? thanks again
