    @T3P3Tony said: physically controlled by an external device (either an industrial PID controller, or an Arduino running its own PID loop) rather than a heater output wired directly to the Duet. Why? my build volume is approximately 500×500×500mm, so I need more than 3 separate heating zones to get even heat distribution across a chamber that large, and I want each zone monitored by 2 sensors (for redundancy/averaging, so one bad reading doesn't throw off that zone or trip a false fault).

    I'm going to drop this change for now - as it got too complicated - especially as follow on moves don't get invoked unless the previous move achieves max speed - which is sometimes difficult if you are matching small moves with longer ones. I'm still going to continue mostly with a single motion system - but I might try splitting out long W, D & V axis moves into very small targeted invocations of multiple motion systems - if I can work out whether collision avoidance is still possible. Will probably also add some extra diagnostics into the firmware as based on some of this issues I have had with this approach I think my main multiple motion system issue occurs when conditions arise that override all speed limits on stepper moves.

    Spent many hours and meters of PETG, but didn't understand where the issue comes from. Looks like Voron cube with supports reliably reproduces the issue, when done in Slic3r, orca sliced model has no such issues. Additionally, Z speed issue was actually affecting all seams and was effectively solved by previous recommendations, while that underextrsion looks somehow related to supports, especially short ones. I managed to briefly increase the quality by reducing the retractuon speed to 10mm per s, but it didn't fully remove it. At the moment, i decided to give up on that and consider pancake direct

    Hi, So I hadn't used this printer for a while, and actually upgraded it to a RPi5, and I added an SSD via a USB adapter. (wow is it so much faster with the SSD, I should have done that ages ago) It was running fine, and I did some prints. Then again it sat. The next time I booted it up, there was a bunch of updates to run, including a firmware update. Everything seemed to go OK, but then on the final reboot, I got the message where Duet Control would not connect, network unavailable. Looking at the log, it tells me that it Failed to open gpio device /dev/gpiochip0 When I do a gpioinfo, I see gpios 11 through 15, but no zero. If I do sudo nano /opt/dsf/conf/config.json I can see the reference to gpiochip0 Is it broke? Should I still see chip0? Did the firmware upgrade to the RPi or the Duet3D remap the gpio numbers? Do I rename the chip0 to one of the other chip numbers? If so, how can I tell which one (11 through 15) is correct? Any help would be greatly appreciated. Thanks. Michael

    @Adrian52 apologies on missing your response. This is unexpected, but is likely due to the in-and-out direction the nozzle travels vs regular perimeters. In the upcoming version, we have enhanced Serpentine to optionally include an external perimeter loop that should combat this - but it shouldn't be required. The nuts and bolts we tested with fit together without issue, but we did not attempt a "print-in-place" multi object design like this. We'll do some more testing. Feel free to open an issue on our GitHub with your project files. Thanks

Would only be a requirement for one stepper motor to work at a time.

    I've managed to destroy a fair number of the Smart Effectors as I experimented with different hardware. The older ones used 0.1" connectors. I could make all the cables that interfaced with the Smart Effector. Now that it's using JST PH connectors, I can not reliably make the needed cables. I've had to buy the cables and then splice them into my system. None of my fans have JST PH connectors on them. A couple days delay getting a compatible cable so I can interface my parts fan.

    @droftarts Thank you for the further information Regards the M665 Height parameter I set it using the following method. use G30 S-1 to get to the probe height. Using a 0.1 feeler guage I jogged the nozzle so it gripped the guage. then using G92 Z0.1 Issued a G0 Z390 just before the tower endstops triggered. then jogged +0.05 on till the switch were hi-lighted. (Watching the DWC tool position the XYZ become hi-lighted when the switch is triggered.) So recorded the X,Y,Z Z values when the position became highlighted, then sent the axis back down to G0 Z150 and adjusted the screws on the axis carriage that sets the trigger point. Repeated this step until on the switches triggered at the same height (eg Z397.5). then adjusted the M665 Value Reset the machine using M999 then G0 Z0.1 and confirmed the bottom of the nozzle was just on top of the feeler guage. I have been having trouble with using the file editting over wifi so have been resorting to removing the SD card and editting what ever there, so I did wonder if it was not getting the correct inofrmation. I didnt know about the M500 additional parameters so thanks for that. Danny

    @jay_s_uk OK, not natively supported but still viable (after some rewiring) - tailoring the connections should not be a big deal, and the "Important Notes" now make sense in the context of your statement. Once again you helped me understand Chinese . I don't need the tach signal by the way. No special firmware configuration necessary. I checked: GPIO24 is actually already being used for BLTouch; GPIO26 is for rgbled (I think those are supposed to provide PWM output signals, but not intended for fan control). I never thought to have to ask about connecting a fan... you live and learn. EDIT: Anyone else also learning, see also: Fly RRF-36 fan tachometer connection -- Solved

    @NineMile The more important question: does the controller allow you to set negative torque or will it quit with an error. Also keep in mind, that the brake motor is in fact a generator. Make sure your powersupply can handle that. Battery-driven it might be able to actually regen-brake, but that requires a different PWM-algorithm. We did that with two 200kW motors and we were trembling when we first fired it up...

    @emcar_arch I think it's cleaner to have the driver enable interface accept multiple drivers because that happens naturally when an axis has multiple drivers and for kinematics such as CoreXY and delta. The local interface can either execute enable commands as they are generated, or batch them by accumulating a bitmap of local drivers to enable, and then enable them when the move processing is complete as is done for CAN-connected drivers.

    @3form Good point. If CAN42 also started at 0.35 and only came down after many runs, the current series was confounded by the number of runs and both drivers show the same thing. Before you take anything apart: after a run that gave 0.33, jog Z a few mm and run M569.6 again. Each run only moves the motor about 0.1 mm, so if it goes back to 0.35 at the new position then the value isn't really coming down. I would still uncouple one motor from its ballscrew, precisely because both motors behave the same. It is one test and it settles the question: bare motor with the brake still fitted, run M569.6. If it reads 0.10 to 0.15, the motors, encoders and boards are fine and everything you are measuring is in the mechanics. If it still reads 0.3, the drag is in the motor or the brake. Yes, P42.0 and P43.0. More interesting is that you drive the brakes with M950 and M42. Which revision are your 1HCL boards? On v2.0 the BRAKE header is a two-pin circuit, brake.pos and brake.neg, and both have to be driven to energise the coil. M569.7 does that; a GPIO configured on "brake" only drives one of them, in which case the brake would not release at all. Since your axis clearly moves, you are probably on v1.x, where that pin is plain OUT1 and M42 is fine. Worth confirming, and also worth checking what voltage the brake actually sees: M42 switches the full jumpered supply, so a 24V brake on a 48V rail is being overdriven. M569.7 with V24 would PWM that down.
