must be no more than 0.1 ohms per conductor
hello, sorry for asking. i am not electronic guy so i alittle bit blank with 0.1ohms per conductor. what this means
i check i use stp lan cable to do it and i check in the internet it is have resistence about 150ohms i cannot use this cable?
-
@lifeform That would be measured with a multimeter.

@theshabobo @Phaedrux @deckingman I'm having the exact same issue as described here. Same garbage commands, and tool being de-selected.
Current firmware versions:
Board: Duet WiFi 1.02 or later + DueX5
Firmware: RepRapFirmware for Duet 2 WiFi/Ethernet 3.2.2 (2021-02-11)
Duet WiFi Server Version: 1.23Has there been any other instances of this? I am using prusaslic3r and was not having this issue before the upgrade to RRF V3, which I performed a few days ago.
I am using a 4 pin paneldue cable. There is only one small section where it is near a stepper motor (probably 5mm cross section) and the rest of the cable is in an aluminum extrusion, so it should be shielded.
There may be interference somewhere, but I think that would have shown up before the upgrade to RRF V3
Baud rate for PanelDue is 57600

V3 definitely seems more sensitive to interference. You can try lowering the baud rate to make it more tolerant.
What paneldue firmware version are you using?

Duet WiFi Server Version: 1.23
Unrelated, but the wifi version for 3.2.2 is 1.25.
-
@Phaedrux Paneldue firmware is 3.2.11
I'll look into updating wifi server. I thought that all was updated with the combined firmware when I updated to 3.2.2.
-
@Phaedrux Looks like the baud rate change might have fixed it. Any recommendations on wire? I want to re-wire some of my stepper motors with shielded wire to cut down on interference, can't seem to find any good wire.
-
Any decent gauge wire should do. I like to do a braid or twist which seems to help with crosstalk without shielding. I hear people mention silicone wire as nice to work with. I've only ever used some cheap spools of 22 gauge wire on amazon for low current DC applications. Nothing special. And for AC wiring some larger gauge stuff from the local auto parts store.
-
@Phaedrux Well I lied, still getting communication issues. I replaced the SD card with a brand new one, and I moved the stepper motor wire that was near the paneldue wire so there is 4+ inches of separation. The only other wire near it is a mechanical endstop switch. Any other ideas? The paneldue does not have a SD card in it.
-
How long is the wire run?
-
@Phaedrux The 4 pin wire is 1000mm long. I bought it from filastruder, who also offers a 3000mm cable, so I figured the 1000mm cable would be fine.

-
@Surgikill Yeah that should be within spec.
I'll try and find out what was ever determined the last time this was reported. It's been found a few times but I don't think there was ever a definitive cause for why it becomes apparent in RRF3.
Can you measure the resistance of the wires in the cable?
-
@Phaedrux Thanks. I'm still going to rewire this just to tidy it up. Maybe it will help.
-
@Surgikill "The length of the 4-way cable is not critical, however the resistance per conductor should not exceed 0.1 ohm. "
-
@Phaedrux I can measure it and see. Definitely still having issues with my tool being de-selected.
-
@Phaedrux Well, the ground wire read 0.2, but the resolution on my multimeter is only 0.1, so not sure how accurate it is. Length is less than the 1000mm, it's only about 750mm.
Any way I can mitigate this until we find the issue? I can't get a print completed.

This may be inconvenient but could try disable or disconnect the paneldue. What version of PanelDue is it? What PCB version of Duet?
-
Duet 2 wifi PCB V1.04.
Paneldue 7i.I did a print, couldn't see any garbage errors on the paneldue, but I didn't get any tool unselected errors. I cut my wire in half and re-terminated it, so hopefully that mitigates any issues. The wire is running decently close to a stepper motor and a drivers (around 2-3 inches) and there's not much I can do about that. I have some shielded wire coming, so that might help.
-

A braid for both wires might help. I've got my PanelDue wire running along side a stepper for ~1 meter since it's right next to the CorexY B motor and they run down the frame and back to the Duet box. I think I have a braid in the panelDue wire and pairs of the stepper motor are twisted together. So for interference I think I'm in worst case, but the braid/twist seems to help.
-
@Phaedrux I believe the stepper wire is braided, not sure. It might just be the paneldue wire. The stuff I got from filastruder is like 30ga. Re-wiring with shielded 22 gauge should hopefully fix it.
-
@Surgikill The plan going forward is to change from using a checksum to CRC, but that has not been implemented yet.
