@chrishamm that indeed did the trick. It also fixed the issue with the order of powering the device. Many thanks.
@chrishamm I've a duet 3 mini 5+
I've updated to V3.4.6 but the issue persists, I don't think it is my python code as the issue is also there when I do the following:
plug in USB cable into PC
open YAT terminal
send M115 to test for connection, which than responses as intended
close YAT
restart laptop
open YAT terminal
send M115 to test for connection, no response, while the terminal at the bottom right says that the com port is open and connected
to restore the functionality:
Could you let me know if by performing this sequence of events, you obtain similar results?
Dear Phaedrux @Phaedrux
Sorry for the missing details, I'll explain the scenario more clearly.
I've a thirty party software that uses python to send single line Gcode to the duet over USB, the USB is connected via a USB isolated (adafruit, the recommended one by duet). When I leave my USB plugged into the laptop and I restart the computer, the communication with the Duet stops, for example if I after restarting the PC open the YAT terminal and send something like M115, i get no response.
If i unplug the USB cable and plug it back in, the connection is restored and I can send codes via YAT as usual.
Furthermore, If I power my duet by VIN first and then plug in the USB cable the same behaviour is present as in no communication to duet via programs like YAT. With or without the USB isolator makes no difference (I only test this if my laptop is running on batteries) so the problem is not with the USB isolator.
I've checked and tried to change USB suspend behaviour, but this did not fix the issue.
Is there something else I could try?
Kind regards,
Dear All,
I'm controlling my duet over USB, but i noticed that when I restart my laptop, while the USB is still connected to the duet, that upon start up, the duet is not responding anymore. It than requireres me to unplug the USB and to plug it back in, which is a bit enoying. I also noticed that when i power my duet first from the VIN and than plug in my USB, it is not responding aswell.
I there any way to circumvent this behaviour?
Kind regards
Dear Duet,
I would like to power up my duet (the Vin voltage) over USB. So sending a command that switches a relay so that 24v is now supplied to the board.
How would i go about this, should i use the PS-on and correspond ground next to it to go to the relay and than send M80 over USB to power it on?
Kind regards,
@dc42 many thanks for the response, the panels / enclosure is anodized aluminium, which is not conducting, so the gx-12 are not really in continuity with the enclosure (at least in a reliable sense), maybe if I would screw them overly tight it would. However, the enclosure is floating and no AC is coming in but only 24v DC, so grounding the whole enclosure is not necessary as far as I'm aware.
The power supply I'm using only outputs a floating DC voltage
(class 1) through the barrel jack connector, therefore I'm a bit confused about your last command. Would the shield still work/be effective if it is only connected to the negative terminal of the floating 24v dc PSU as in the following image:
To me, it just looks a bit odd..
regarding connecting it to the stepper motor body, I've encountered many conflicting opinions on various build forums.. with many people saying you should only connect it to one side (controller side) so I'm still a bit in doubt about what to do with it.
Dear All,
I've been going through a lot of posts but couldn't find a clear answer, while this might be relevant to others as well.
I'm designing a simple xy motion system with a duet 3 mini 5+ only two linear actuators (nema 14 running at 0.7A, leadscrew with linear rails). There is not a lot of power consumption so a 3A 24v power supply is more than enough, therefore I use these desktop power adapters (Mean Well GST90A24-P1M). The duet is housed in an anodized aluminium enclosure with only cut-outs for mounting the antenna, dc barrel adapter and female GX12 connectors. all wires inside the aluminium enclosure have ferrite chokes around them close to the board.
For the stepper motor cables, I'm using twisted pairs of cables (75cm long) with an aluminium foil shield around them and of course the black isolation. Now I think, going over all the posts about EMI / EMC, this should be sufficient, since this is only the bare minimum the duets are capable of doing, with low motor currents, twisted pair wires and ferrite chokes.
Now since the cables have shielding, I'm thinking of further improving the EMI/EMC capabilities by somehow grounding this shield, however, I'm a bit uncertain on how to do this with the power supply I've at hand. I'm not too afraid of static charges on the motor side since I'm not using any belts so I prefer to not connect the shield to the motor for aesthetic reasons
should I do it as in the following diagram? So connecting the shield to the outside of the GX-12-4pin connector, and then wiring the outside of the GX-12-4pin connector to the gnd terminal on the duet board inside the enclosure with each outside GX-12-4pin connector connected to each other?
many thanks for your fast response, so a clas I or class II power supply brick will not make a difference?
Kind regards
