  @smece said in attaching a joystick / gamepad / industrial controller ..: I'd have to remove the PD The panel need not be removed. It is perfectly OK, hardware wise, to "Y" connect to the RX pin (on the Duet) to two TX sources. The pendant/game device can transmit during quiet moments, when the Panel is not transmitting. In order to do the best possible job of that, the pendant/game should also be have its own RX pin (or a secondary RX pin) "Y" to the lash up described above, and listen before transmitting. This will not be perfect; there is always the possibility of both devices transmitting at the exact same instant (exact being defined as one character time)... however losing a single message is not a big deal in this usage scenario. In short: Hook them both up. It will work amazingly well.

  For future reference, this issue appears resolved as RRF 2.04RC4 changes the behavior of output buffers.

  @georgepaul said in Connecting multiple Z probes for multiple independent Z axis: ZideX I think I see what you mean. That printer design has two independent extruders, each on its own X carriage, and the height of each X carriage is controlled by a separate Z motor. Correct? In RepRapFirmware 2 you can switch between different types of Z probe using M558, and some types have their own G31 settings. RepRapFirmware 3 will be more versatile. You can already configure multiple Z probes in RRF3 (each with its own type and G31 parameters), all that's missing is a new M-code to switch between them. With either firmware, you can use the tool change files to select the Z probe you want to use and to switch height maps.

  It does not flash (or come on) at all. I will do what you suggest and see what happens.

  I'm sorry that you appear to have a faulty fan output on your DueX board. I authorise E3D to replace your DueX5 under warranty.

  @johno4321 said in Stepper motors & Z lead screws: As I understand it changing to a 0.9 degree stepper will increase print precision but decrease maximum motor speed - is this correct? yes it will reduce max speed. but you wont be operating at those speeds anyway. for a discussion of 0.9 vs 1.8 on prusa printer have a look at this. https://forum.prusaprinters.org/forum/original-prusa-i3-mk3s-mk3-user-mods-octoprint-enclosures-nozzles-.../stepper-motor-upgrades-to-eliminate-vfa-s-vertical-fine-artifacts/ blv recommends 0.9 x and y degrees for his newer project, the blv qube. you might also want to replace the couplers with jaw couplers, or place one ball bearing inside the coupler to reduce any springiness of those couplers.

  @Nuramori said in New setup after errase and wifi antenna switch: There's clearly a missing SMD at the upper left corner of the SD card holder, R73 There are DNP components (including R73) on the board. See the schematic: https://github.com/T3P3/Duet/blob/master/Duet2/Duet2v1.04/Duet2_1.04c_Schematic.pdf

  no the bltouch is connected to the z probe port, while the endstops would be connected to the z stop port.

  @mpentenr said in Using Duet 3Mainboard with external stepper drivers: @dc42 said in Using Duet 3Mainboard with external stepper drivers: Thanks. Are you using the encoder input on the stepper driver for the pellet extruder? What is the maximum rotation speed needed by the pellet extruder motor? No, I am not using the encoder input (at the moment, perhaps I need to). The max rotational speed will be arounf 500 rpm, because of an 10:1 gearbox on the stepper, so up to 50 rpm at the pelletextruderspindle At the moment the pellet extruder is highly experimental, so I don't know the exact values. Time and experiments will show

  If this will work it's definitely of interest (Just running a base Wifi with no deux) to me as found it got hot enough to soften the ABS so had to abandon the design!

  @tcj said in Maestro and other types of 12864 LCD?: Thank you for the information. Do you know less "bulky" LCDs than the typical reprapdiscount type? I'm sorry, I am not familiar with all the different 12864 displays on the market. We chose to support the RepRapDiscount because it has been widely cloned and is in widespread use. When we revise the design of the Maestro, we'll look at providing another level-shifted output so we can support these other types of 12864 display.

  @Baal said in Ender 5 PLUS Y-Stepper Maestro: Is this current to high for StealthChop to be quiet or is this fine? that current is fine for the tmc2208. the voltage is more important. For stealthchop2 you want 24V.

  @dc42 Thanks for confirming that using a spare heater port is a better option for an air pump. Yes, I will be installing a flyback diode. However, would it be beneficial if I use two? One screwed in at the heater port terminals to be closer to the mosfet, and another at the motor to reduce any interference created by the PWM? Also, will the heater port pwm up to 25khz, as recommended in other threads?
