Re: Thoughts on a piezo touch sensor - 8 days ago

Have you seen the Smart Effector? It uses a built-in strain gauge to detect nozzle contact.

Re: Help with Simple Triggers for Switches - 24 days ago

Hi Techman2930, please post on where our support staff and the RepRapFirmware community will be pleased to help you. It may help if you post a M122 diagnostic report taken after the fault has occurred and before you power down or otherwise reset the Duet.

Re: Delta calibration point triggering (way) before reaching the bed - 4 weeks ago

I agree with your diagnosis. What sort of rod end joints are you using? Perhaps one of the joints between the effector and the Z tower rods is hitting its limit and stressing the effector and then the piezo module.

Re: Core ZXZY Build Log - 2 months ago

Looks interesting! As the kinematics is linear, RepRapFirmware supports it already, without even having to recompile.

Re: Kossel, Z-Height if Calibration Cube is way too small - 2 months ago

Rod length only scales X and Y. Z scale is determined by the steps/mm setting of the tower motor drivers. Get the Z scaling right before you adjust the XY scaling.

Re: Establish a "Firmware - Klipper" folder in "Firmware Folder" - 3 months ago

If a Klipper firmware folder is added then a RepRapFirmware folder should be added too. However, most Klipper support seems to happen on Discord, and most RRF support happens on the Duet 3D forum for Duet boards, and on the same forum or on Discord for STM boards.

Re: FEED HOLD - 3 months ago

You can get a reasonable approximation of feed hold by enabling segmentation in RepRapFirmware using the M669 command. True feed hold on planned for version 3.5 of RRF.

Re: Duet2 WiFi V1.04 - 3 months ago

The board will only connect to Bossa if you first erase the firmware, by placing a jumper across the Erase pins. Remove the jumper before you use Bossa to program the board. The command M552 S0 does not connect to WiFi, it merely puts the WiFi module in Idle mode. You can then use M557 to program the SSID and password. See . To get a faster response to your questions, I suggest you post them at

Re: reprap full discount graphics controller gets garbled sollution ? - 4 months ago

It's well known that attaching a graphical LCD overloads the 5V regulator on the Arduino, causing it to overheat, reduce its output voltage, and often fail. Connecting USB provides an alternative source of 5V power. 12864 display modules vary in the back-light current they draw. Some have a zero ohm back-light resistor fitted.

Re: Elephant Foot on slic3r ?? - 4 months ago

It's likely that your Z homing isn't quite right or your Z probe trigger height is configured too high, so that the nozzle is a little too low when the first layer is printed. It could also be that you are Z homing and probing correctly but doing it when the bed and hot end are cold, and when they have heated up the distance between the nozzle and the bed decreases because of thermal expansion.

Re: Edit Marlin for Polar Coordinates - 5 months ago

Marlin is not the only firmware. RepRapFirmware supports polar printers natively. You don't even need to recompile it. It runs on 32-bit boards such as a Duet and good STM-based boards.

Re: Maybe the World's Lightest Extruder - 6 months ago

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 ste

Re: Ender 6 COREXY issue in Marlin - 6 months ago

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.

Re: Ender 6 COREXY issue in Marlin - 6 months ago

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.

Re: Extending cable for paneldue - 7 months ago

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

Re: Extending cable for paneldue - 7 months ago

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?

Re: Issues with custom delta printer / RRF 2.05.01 - 9 months ago

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.

Re: Skewed print in marlin 1.1.9 & bugfix2.0.x with external drivers - 10 months ago

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.

Re: Set up temperature sensor m308 - 10 months ago

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 throu

Re: Servomotor disaster - 10 months ago

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.

Re: Remodeling my existing printer for better prints - 11 months ago

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.
