Bear in mind that the current that can be absorbed by the 33 ohm resistor will be limited. For example, if you use a 24V supply then it's only about 700mA.by dc42 - Stepper Motors, Servo Motors, DC Motors
Take a look at RepRapFirware too. It provides a Web interface on suitable hardware and supports input shaping, without the added cost, complexity and startup time of a Pi. It has other features that Klipper doesn't have such as conditional GCode. It's available for Duets and for some SKR-based boards.by dc42 - General

We recently released RepRapFirmware 3.4.0 with many new features, including these: - Input shaping, which reduces the resonances that cause ghosting on prints, allowing better print quality at high print speeds - Heater feedforward based on extrusion rate, which helps maintain extruder temperature when using high flow rate extruders - The file listing in the web interface and in the file informaby dc42 - Firmware - mainstream and related support

I have a 4-pin Ormerod proximity sensor and it includes a 10uF 10V tantalum capacitor. My best guess is that it is the same component that has failed in your 3-pin sensor. It's likely failed short circuit, which is why the PCB traces are burned. Are they still intact? If you are in the UK as your username suggests, I could send you my 4-pin proximity sensor if you PM me your addressby dc42 - Ormerod
You could save yourself a lot of work by using a Duet 3 Mini main board and a CAN-connected Duet 3 Tool Board.by dc42 - Let's design something! (I've got an idea ...)
QuoteVDX ... beside big flat areas -- you too can think about "vertical farming", where the plants are groving in vertically aligned shelves, where the water from the top rows is rinsing down ... then the "bot" could be a XZ(Y) system with a stable frame, only relying on belts or wire-driven linear gliders There is at least one system using RepRapFirmware in this way.by dc42 - Developers
Duet 3 Mini can support 2 extruders as it comes, and up to 4 extruders with the 2 driver daughter board. It's available in WiFi and Ethernet versions.by dc42 - Reprappers
If the firmware doesn't see a rise in temperature from the thermistor, then it is likely to turn the mosfet off after a few seconds. Perhaps the hot end heater cartridge or the wiring to it has developed a fault?by dc42 - General
It sounds to me like a combination of low frequency noise, possibly caused by running the stepper drivers with no or very low microstepping, and a higher frequency rattle. If you move the three towers individually using G1 H2 moves, do they all make the same noise?by dc42 - Delta Machines
If you are connecting via USB then you will need to run a terminal emulator program on the macbook. Alternatively, connect it to your router using an Ethernet cable and then use your router administrator page to see what IP address is it using. For more help, try posting at .by dc42 - Fisher
You have specified in your config.g file that you have separate Z endstop switches for each motor: QuoteM574 Z1 S1 P"zstop+e1stop" ; configure active-high endstop for low end on Z via pin zstop Most likely there is a bad connection to one of the switches, so that it appears to the firmware that it is permanently triggered.

The response time of the Duet when the Z probe input changes is a few milliseconds when in analog mode (M558 P1) or filtered digital mode (M558 P5), and no more than 1ms when in unfiltered digital mode (M558 P8). My best guess is that you have a bad connection between the piezo output and the Duet Z probe connector input pin, so that it is taking some time for changes in the signal level to leakby dc42 - General
You could use a global variable to record whether bed.g has been run, and in bed.g you can test and set that variable. To detect that the Z motors have powered down you could monitor the Z homed status. A complication is that the Z homed status will also be cleared at the start of execution of a G28 command.by dc42 - CoreXY Machines
Correct, I meant don't use ^ in front of the pin name.by dc42 - General
No, that won't work. But you can get non-polarised electrolytic capacitors.by dc42 - Experimental and Hobby
It sounds like you have used high value resistors in the voltage divider. Try using lower value ones.by dc42 - Reprappers
The Duet 3 Mini has permanent pull pullup resistors on all IO connector inputs. It's best not to use ^ in the port name to enable the internal one because that will reduce the noise margin.by dc42 - General
For delta printers, nozzle contact probes are best. This is because it is very hard to get the geometry of a delta so accurate that the effector remains perfectly level as it moves in the XY plane, and any tilting will change the relative height between the nozzle and an offset probe. Types of nozzle contact probe include: - Duet3D Smart Effector - FSRs (force sensitive resistors) or piezos mouby dc42 - Firmware - experimental, borrowed, and future
Yes it looks as though the heat task didn't kick the software watchdog within the timeout period. The SPI code was working on the SAM4E8E with the PDC way back when I first implemented it, but I was unable to run the SPI interface as fast as I could with the DMAC. So you may need to reduce the SPI clock speed in the WiFi firmware. I suggest you reduce it to 10 MHz or lower until you have it workby dc42 - Firmware - mainstream and related support
If you get unexpected resets, run M122 and look in the resulting report for the "last reset reason". If tit reason is "software" then look at the "software reset reason". This gives details of the reason for the reset and a stack trace at the point that the reset procedure was initiated.

I used 2020 extrusions for the uprights originally, but upgraded to 2040.by dc42 - Delta Machines
I agree, 2020 isn't stiff enough for that size printer. I use 2040 for my 1m high delta.by dc42 - Delta Machines
I suggest you post at . You will get much faster response there. In your post, please say which Duet you have, which main firmware version, and (if applicable) which WiFi firmware version.by dc42 - Duet
The debugPrintf function sends output to the USB port. So connect to that port using a PC running a terminal emulator program.by dc42 - General
You are right, you will need to swap the endstop connections over.by dc42 - Delta Machines
Yes you can remap the drives using the M584 command. You will also need to change the M574 commands that assign the endstop inputs.by dc42 - Delta Machines
