  @JoergS5 agreed. My hands are bit tied too with how the wiring is as this is a modified Evo22 so I’m using much of the factory wiring, I just replaced the board and the extruder. The rest is inherited from the manufacturer. So I’m glad I can work around the issue.

  @Kiwi3D said in External SD Card not Reading (Maestro with 12864 Display): @dc42 Hi David, Ive just got my Maestro Zaribo built...and facing t he same issue. I'm on 3.1.1 12864 rotary encode is working and can use the screen fully. SD card on the screen is working from DWC 3.1.1 but not from the 12864 Thoughts? Many thanks Ray Probably best if you start your own thread.

  @mrehorstdmd unfortunately there might not be any internet at all. The units might end up in remote locations.

  @zapta Thanks for the answer. I've tried it yesterday - but it seems that Duet is not recording any data from the sensor. I configured the sensor as following, just to log data when printing : M591 D0 P7 C"^e0stop" L0.07853981634 R90:110 E3 S0 but it did not receive any data. Any ideas on what I can try is highly appreciated. Thanks again

  PINDA is the prusa product but similar probes exist in aftermarket. According to the wiki, capacitative probes have low precision / repeatability (see https://duet3d.dozuki.com/Wiki/Choosing_a_Z_probe). If you heat the bed before probing, you may get improved results by switching off the bed heater during probing (see M558 B parameter).

  Status 23 May 2020. Bogged down in the Oled. ESP32 can be programmed a number of different ways "Arduino" compatible libraries via the Arduino IDE; Arduino libraries via PlatformIO, several Python variants, and its native (from the manufacturer) platform/framework Espressif32/ESP-IDF. For "reasons", I'm pursing that last one, the native set up. However... for years there have been TON of LCD and OLED libraries out there for the Arduino, and these are very quick and easy to lightly refactor for the ESP32 Arduino-ish setups. Therefore, nobody has produced any LCD or OLED libraries for the 'native' ESP-IDF framework. Being somewhat hard-headed, I'm in the process of adapting one of the libraries (specifically LovyanGFX) so that it is pure native ESP-IDF. What a meticulous pain in the kiester this is turning out to be... So, anyway, summary status: Lots of pieces working, need to be integrated into a whole, and bogged down on the OLED to the point I may push through; or I may change course.

  @baird1fa With the default installation (in regards to my setup with the 7" Pi touchscreen display) - the screen doesn't blank; however, it will blank after installing xscreensaver sudo apt install xscreensaver In the desktop -> preferences -> screensaver application/setting you can pick a few default screen savers, I use the Mode -> blank display only (with a 5 min timeout). This uses the least CPU and frankly saves screen burn in (what I needed). Note: If the Duet 3 is only running from 5V USB input, the display blanks, but the Duet still draws a yellow lightening bolt in the upper right corner to let you know the board is still not powered by the main supply. If the main supply is powered on, the display blanks fully (aka no yellow lightening bolt)

  P.S. I always start my SD card for a Duet Pi with the Duet provided image (plus and update/upgrade, of course). It seems lots of people start with other flavors of Raspbian or even other Distro, and it works. I am just being conservative regarding "reproducible" behaviors on the Duet systems.

  then you don't need both to pause; simply assign it as an enstop and move until the endstop triggers? more than one way to skin a cat. I think there should be an example of a duet running a mmu if you go looking you may find some inspiration

  @CarlBosson said in controlling a heated fan in my enclouser: I find that now it is set up, the controller for E1 gets an error because it expects a change in temperature equal to 1.7 degC persec. Ok thanks for clearing up the fan/heater confusion. In order to solve the error of not heating up fast enough you will need to do a PID autotuning of the heater so that the firmware can generate a model of the heaters performance. to do this you may need to increase the dead time though. https://duet3d.dozuki.com/Wiki/Connecting_and_configuring_a_chamber_heater https://duet3d.dozuki.com/Wiki/Tuning_the_heater_temperature_control

  @Dave1167 said in Duet 0.8.5 and BLtouch 3.1: Am I correct in thinking I can go ahead and connect the probe to the 0.8.5 Z probe socket without any additional resistors or diodes etc. It should be safe to connect the BLTouch black and white wires directly to the ground and IN pins on the Z probe connector. You will need to supply +5V power to the BLTouch, and you will need to connect the BLTouch control input to a PWM-capable output on the expansion connector.

  What Duet are you using? How do you have it wired up? What firmware? When the BLTouch triggers the 1000 in the probe status may only show very very briefly or not at all. It's not a good way to test if the BLTouch is working. Check this instead https://duet3d.dozuki.com/Wiki/Test_and_calibrate_the_Z_probe

  @invalidusername As a long time user of Diamond hot ends, I'd say that you've made the right decision. I know very little about Deltas, and I have seen Diamond hot ends mounted to them (albeit not water cooled) but these are still seriously heavy beasts and 5 Bowden tubes or flex shafts trying to pull an effector in all directions would be a concern I would have thought (but I know very little about Deltas so might be wrong).

  Thanks for the link and explanation. That's a really cool feature, but I'm not sure if It's something I want to implement yet. My end goal here is to get things back to working well, then to tear it apart again and convert it to the ReDuplicator.

  Yes. Via serial, I2C, or simple single logic pins. As mentioned, be sure you use a 3.3V arduino. Do you have an example in mind?

  You've not factored in the AC heater you want to use yet? That will be on top of the PSU requirement. Don't forget if your PSU is 500W it will be consuming more like 625W on the mains side. Your AC heater will be added on top of the 625W. Edit: Unless by 'power supply' you mean the total power consumption of your system...

  @daxzero said in External stepper motor on Duex 5 GPIO port.: @dc42 said in External stepper motor on Duex 5 GPIO port.: are you aware that there are 2 sets of step/dir/enable pins on the CONN_LCD connector? yes, but i used it for this setup >>> duet 2 wifi + duex 5 + PanelDue 7i im gonna used all the stepper driver and motors >>> duet 2 wifi + duex 5... total is 10... and i want to add 1 more stepper drivers and motors on to GPIO. So use the CONN_LCD connector. It's not used by PanelDue. https://duet3d.dozuki.com/Wiki/Using_external_stepper_motor_drivers

  I'm glad you got it working. Using hex values might work if you put quotation marks around each one one individually, but I haven't checked this.
