      I suggest you upload this zip file for 3.4.5 to ensure you have everything up to date.

      https://github.com/Duet3D/RepRapFirmware/releases/download/3.4.5/Duet2and3Firmware-3.4.5.zip

      Then add T0 to the end of your config.g so that your tool is selected at startup.

      @cvmichael to set up a static wifi IP address, you need to include the IP and gateway addresses in the M587 command that you use to program the SSID and password into the wifi module. This is so that every SSID you program in can have a different IP address or use DHCP.

      @CVMichael said in Upgraded firmware to rrf 3.01-RC1, lots of problems:

      For M581, I just could not get it to trigger with exp.e6stop on the Duex5

      That's because exp.e6stop is a pin on the expansion connector, not on the DueX5. Use the correct pin name beginning with "duex.".

      @CVMichael said in How to reset error: Temperature reading fault on heater 1:

      Just discovered something new.

      When I get the error, I send command "M562 P1", and it does not show "fault" anymore, then I use the web interface to change temperature, it sends "G10 P0 S120", and that does not work!

      BUT !! If I send command "M104 S120", then it DOES WORK, after the M104, sending G10 P0 S120 (or any other temp) works after that.

      So this looks to me like this is a bug in the software

      It's not a bug because resetting a heater fault turns the heater off. An alternative way to turn it back on is to reselect the tool using a T command, e.g. T0 if you have only one tool.

      @cvmichael said in TMC2660 on stepper channels 10 and 11:

      "ENN - connect to ENN on the expansion bus" - what pins? I only see "En 10" and "En 11" on the CONN_LCD, but I don't see any 10, 11 on the expansion bus.

      I mean the expansion bus on the 50-pin connector. You will need to tap into that bus, e.g. by clamping a 3rd IDC socket on the 50-way ribbon cable. Or you could have a couple of 50-way connectors on your expansion board, then use a short ribbon cable to connect the Duet to your expansion board and another ribbon cable to connect the DueX to your expansion board.

      "CSN - connect to the corresponding ENABLE pin on CONN_LCD" - is this the "En 10" and "En 11" ?

      Yes.

      What is the "Stop 10" and "Stop 11" ? pins 3 & 4 on the CONN_LCD, is this for the CSN ?

      No, those are for endstop switches.

      "SDI, SDO, SCK - connect to SPI1_MOSI, SPI1_MISO and SPI_SCK on the expansion bus" - I already have a Duex5, and I don't see any pins for the SPI1 (I see quite a few for SPI0 though). Does this mean that I will have to sodder wires in the back of the Duet PCB to bring the SPI1 to my motor driver PCB?

      See my comments on ENN above.

      Since I want to make a PCB for both channels 10 & 11, I assume SPI is connected in parallel, but CSN is separate?

      All the control inputs are in parallel except for CSN, STEP and DIR.

      I created a schematic, if you have some time to take a look at it, and let me know if you see any mistakes:

      The sense resistors should be 0R05 not 0R1 VCC_IO should be +3.3V not +5V. There should be a 100uF electrolytic cap on the +24V supply close to each driver We have 1nF capacitors for each output to ground to help with EMI and immunity to inductive spikes

      See the Duet schematic at https://github.com/T3P3/Duet/blob/master/Duet2/Duet2v1.04/DuetWifiv1.04a_Schematic.pdf for how we connect the TMC2660s. The resistors shown as 0R051 are 0R050 in recent production.

      @cvmichael said in CNC Mode, Z normally open touch home & mesh:

      Is there a way to put an IF statement to omit those g code if a flag is raised?

      Kind of like "#define flag" and then "if else" in the deployprobe.g and retractprobe.g file, just like in C/C++ ?

      Conditional GCode is not available yet, but is scheduled to be implemented.

      @cvmichael said in Motors at 24V, everything else at 12V?:

      I don't understand how you do that?

      The Duet switches PWM on the ground side, so the live side could be supplied independently.

      I guess if you have a lot of hotends to modify it will be a toss up between the complexity of wiring, or simply replacing the hotend.

      @gavatron3000 do you use a seperate inline fuse for the hotend?

      Yes I have a seperate fuse on each rail voltage. I have 24v 12v and 5v on my machine for various things mainly because before I had a duet I used to run a ramps 12v setup from an ATX supply then when I upgraded to the duet I installed a DC to DC converter upto 24v so the stepper driver's were ran at what was recommended

      I figured it out, after the trigger, if I send command:
      M208 U0:400 S0

      Then the G92 U0 works!

      I didn't realize before, I was using "M564 S0 H0" to move the axis without homing to prepare the printer, and this made the "G1 U0" work after homing (trigger) on U axis, but "G92 U0" not work because it was changing the minimum limit.

      Now everything makes sense!

      Thanks for your help

      I always use the Emergency stop button in the top right of the interface. However that will reboot your printer.

      You may find that the M575 command does a lot of what you want.

      If you are not using a PanelDue then one option would be to connect your Arduino+ultrasonic sensor to the PanelDue port (caution: it uses 3.3V signal levels, not 5V). You could then use the M118 command to send the Arduino a message, and it could response with a sequence of GCode commands to move the tool an appropriate amount.

      BTW, on DWC, could it be possible to let the folder open once the macro is clicked? For now, the folder automatically closes, which is annoying when I want to launch several macros from this folder...

      Your idea is better, instead of making it a menu, it should be a section to expand, and stay open until you click on another section, and have that one stay open.

      Maybe even open when you hover the mouse on top of it, this way you don't need 2 clicks

      @cvmichael said in Duet Wifi - the wifi module turned off/disconnected during print:

      It was a 7 hour print, and after about 5 hours the wifi turned off / disconnected... not sure what happened. The blue LED that is on the Wifi module was off, and the browser was disconnected from the 3D printer. The printer kept going though.

      I don't have the PanelDue, so for the last 2 hours of the print I had my fingers crossed because there is nothing that I could do to control the printer, thankfully my print did not fail. When it finished printing I had to reset the board and wifi was back on.

      This is very concerning, because I have no other way to control the printer. I have a filament monitor, and if the print pauses, I have no way to resume the print.

      Is there a way to reset the Wifi module while it's printing without disturbing the main board ?

      PS. all my other devices on the network were fine, there was no problem with the local network.

      Recent firmware versions auto-reconnect to the access point when they detect loss of connection, so I guess you are running older firmware.

      The maximum recommended continuous current for each fan mosfet is 1.5A, with 2A or a little more allowable for a short time when the fan starts up.

      The 12V regulator on the DueX board has a separate Enable jumper, that needs to be in place for the 12V regulator to work. The fans circuits share the 7.5A fuse.

      @cvmichael said in M591 P7 - figuring out the other numbers:

      I don't really understand your post. Is the 16% tolerance something I should enter in the M591 parameters?

      What I mean is that the R parameter will have to allow an additional +/-16% compared to a sensor with higher resolution; or an additional 8% compared to using 10mm length on the same sensor.

      I tried changing the E10 to E5, but it did not seem to make a difference...maybe it did, but I did not notice.

      It should have increased the reported variability under the same conditions by 8%.

      Also, is there a way to run a g-code file instead of the pause?

      Not yet.

      @cvmichael said in Calibrating extrusion & retraction:

      I figured out the problem.
      I have 5 swappable hotend blocks with different nozzles or dual or triple color. In short, I plugged in one that had a 0.8 mm nozzle, and I had in my mind that I plugged the one with the 0.4 mm nozzle.

      Thanks for the help though. I was sure it was a wrong setting somewhere, LOL

      I've done the equivalent... Cura defaults to 3MM (really 2.something) when you set up a custom printer. I've missed resetting it to 1.75. Several times... as soon as I see that really under-extruded print, I know what to change.
