@cata said in How to connect Z probe, that is connected to 24V VIN:

I will purchase the diodes next monday.
Can I test the output to ensure not burn the duet?

Yes, if you have a multimeter you can connect it between the output and +3.3V or +5V to show when the sensor is triggered.

The purpose of the diode is to protect the Duet if the ground wire of the sensor breaks or gets disconnected.

@t3p3tony said in Data Point on WiFi stability:

@danal Thanks for the report. I am assuming that if the PC had disconnected it would reconnect properly? If that is the case it appears there is something different with the way that the android tablet and duet connect vs the PC and duet. Its also not likely solvable with the DWC reconnect things that @chrishamm has added (because it would not connect even after you closed and reopened the browser). Sounds to be something at the IP level (if you had a ping app on the tablet then maybe try pinging the duet IP after the next disconnect?).

Correct, during that incident, the Chrome/Win browser can connect/disconnect/connect at will.

I will give ping from the Android tablet a try.

What exactly does the M98 error say? You may need to enclose the path to your macro in double quotes. M98 P"0:/macros/my macro.g"

Ok, strange thing 🙂
I have connected my setup today to check the commands for you and I2C seems to work fine. When I'm sending "M260 A3 B65" I can see the state changes according to address being sent:

0_1533907087710_Zrzut ekranu 2018-08-10 15.15.46.png

Of course Duet is still saying "Error: M260: I2C transmission error", but now I know that is because I'm not sending ACK from my side.
So the last time I have probably connected something wrong, sorry for bothering you 🙂

UPDATE!

Replaced the wifi module with ethernet.

and now it's fantastic!..

I'm using a powerlink extender and it seems to be fine, So happy to have it figured..

Thanks once again for all of your help

I'll be in touch!

Best,

Ian

Thank You both the Phaedrux file worked this time. You guys rock👍 😙

If you add parameter F2 to your M563 P0 ... tool definition command, then when the tool is active the fan commands generated by the slicer will control fan 2.

M563 P0 D0 H1 F0 ; Define tool 0
M563 P0 D0 H1 F2 T45 ; Used for parts cooling fan

No, you need to use a single M563 command: M563 P0 D0 H1 F2 ; Define tool 0

M106 P3 S1 I0 F500 H1 T45 ; Set fan 3 (hotend) value, PWM signal inversion and frequency. Thermostatic control is turned on.

You don't have a Fan 3 unless you have a DueX2 or DueX5 connected.

For historical reasons, G31 with no parameters reports the Z probe reading, rather than reporting the G31 settings. You can send G31 T# where # is the Z probe type number (as in the M558 P parameter) to read back the G31 settings.

@sigxcpu said in WiFi once lost never reconnects:

@dc42 until you implement a more complex solution, can't you simply reboot the wifi module on connection lost (if the printer is configured as STA)?

WiFi Router reboot is not the only use case. I often experience losing one browser connection (Android tablet) and keeping another (Chrome on Win10) during long prints. I'd hate to risk them both. Therefore, perhaps some form of individual connection retry/reset would be better.

By the way...

Evidence points to the "hang up" being in the Duet. No amount of browser reset, cache reset, reboot, etc, etc, etc. on the tablet has ever allowed the Tablet-to-Duet session to reconnect. Once the print finishes, a Duet M999 or power cycle always allows a (re-) connect from the tablet.

Thanks for the update. the Molex site does indeed say they are obsolete and that 22-01-3047 is the replacement. I've checked the part numbers and updated the wiki.

Thanks... Working...

I get that too. I think it is a minor bug in DWC 1.22. When it tries to reconnect, it should either use the previous password if it has one, or ask for the password without first displaying the error message.

For the water temperature you need to set up a virtual heater, not use heater 2.

I am curious about this. I have devices on my home network that I can't connect to with my phone unless I disable the VPN client in the phone when I try to connect to those devices. Once I have connected, I can turn the VPN client in the phone back on and it works fine. It's my understanding that part of a VPN function to interfere with ISP surveillance capability is to encrypt all traffic between the device running VPN client and the VPN servers, so I suspect the encryption is causing the initial connection problem. I don't understand why it works once I connect and then turn the VPN client back on. Maybe the VPN client preserves existing unencrypted connections.

@dmkmedia said in heated bed not turning on:

yes it is i just fitted a new board i had spare and it all works now

In that case, please ask your supplier to replace the other one under warranty. If you bought it direct from duet3d.com, see https://www.duet3d.com/warranty.

The PanelDue instructions tell you that the maximum resistance per conductor should not exceed 0.1 ohm. You should check whether 24awg wire is thick enough to meet this requirement.
