Quotearsi But the main problem, which appears with all knife shapes, I have not yet managed to eliminate. The pressure on the filament from the hotend, causes a change in the thread pitch at different speeds of extrusion and therefore the number of steps per millimeter. According to this video, I'm not alone This is why RepRapFirmware supports nonlinear extrusion, to allow for the extruder steby dc42 - Tech-Talk
Glad to help. This is a fairly common issue with CoreXY machines. With the motor connections one way round you can only get left hand coordinate systems, and with them swapped over you get right hand coordinate systems. Changing the direction of one or both motors does not change the handedness.by dc42 - CoreXY Machines
Swap the X and Y (or A and B if that's what you call them on your machine) motor connections. Then adjust motor directions as needed.by dc42 - CoreXY Machines

You can use a 4 wire cables up to at least 2m long with PanelDue. If you really do have comms with both PanelDue and Arduino working off the same port, you could connect both cables to the 4-pin connector.by dc42 - Duet
The 4-pin connector and the ribbon cable connector use the same transmit and receive signals. So you can't use both connectors for different communication. You may be able to pass the PanelDue signals through the Arduino, as we do when connecting a CNC pendant. Alternatively, can you use I2C to communicate with the Arduino instead?

Most likely a wiring issue. Either the thermistor wires are shorted together, or the wrong wires are connected to E0Temp. For more help visit .by dc42 - Duet
Calibration of the diagonal rod lengths only works well if you can probe well outside the normal print radius. I suggest you change to 8 factor calibration. Incorrect tower steps/mm, which can be caused by loose belts or pulleys, can cause calibration to adjust the diagonal rod length.by dc42 - Firmware - mainstream and related support

Most likely the firmware is not meeting the minimum direction-to-step setup time required by the drivers, because of the faster processor. There may be a firmware configuration setting to add a delay to fix this.by dc42 - Firmware - Marlin
As you are talking about temperatures of 200C I presume it is the hot end sensor thay you are referring to. How are you measuring the temperature of the hot end? If you are using an infrared thermometer, it won't give you an accurate reading because the target area is too small, so it will read lower than actual. You can get a more accurate reading by feeding a thermocouple into the hot end throuby dc42 - General
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. For faster response to questions about Duet and Repby dc42 - Duet
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
