    @fcwilt I don't know what the status of Shapeways is but I've been using https://www.jawstec.com/ for some SLA parts.

    Thanks - I will check them out.

    The current folks at Shapeways state they are trying to get up and running again but time will tell.

    @Esteban said in Information on the distribution of calculations on Duet cards:

    My first question arose from the fact that my machine, equipped with a single Duet 3 Mini 5+ card, shows artifacts when turning at “high speed”. I've carried out numerous speed and acceleration tests, and yet (without exceeding the mechanical limits of my printer) at high speed, it still lets gohsting appear in combined/complex movements such as bends, exceeding 120mm/s.

    Which firmware version are you using? 3.6 series firmware is much more effective at reducing ghosting on bends than 3.5 series is.

    @Esteban said in Information on the distribution of calculations on Duet cards:

    So I wanted to know if it's possible to saturate the Cortex M4? And if so, does it simplify calculations for the various movements?

    It's likely that you can saturate it by sending a lot of GCode commands in succession each of which commands a very small movement. If that happens then the print would slow down and perhaps get a little jerky. The only simplification that it performs is that if when the microstep rate gets very high, it calculates the interval between steps every 2, 4 or 8 steps instead of every step and then interpolates te timings of the other steps.

    @Esteban said in Information on the distribution of calculations on Duet cards:

    My second question is whether there's a way / a calculation to know if the calculations required of the processor by GCode are too complicated or not?

    You can get an idea of this by running the print in simulation mode. RRF will do most of the same calculations but it won't generate the steps.

    @Esteban said in Information on the distribution of calculations on Duet cards:

    In the case of expansion board connections, a 3HC, which board will perform PWM, motors and temperature monitoring calculations? In a certain logic, each board only performs the calculations for its own sub-components (except for the main board, which also reads the code and compiles the information received by the CAN to display it on the screen)?

    The main board does all the GCode processing and queues the commanded moves. For motors connected to expansion boards, the expansion board applies input shaping and generated the step pulses. On Duets, all PWM output is done by hardware. Management of heaters is done by the board that the heater is connected to.

    @Esteban said in Information on the distribution of calculations on Duet cards:

    SBC mode can help relieve the main board of certain calculations?

    In SBC mode the parsing of GCode files, the management of the filesystem and typically the user interface are tasks managed by the SBC. The Duet main board still calculates the moves.

    @Esteban said in Information on the distribution of calculations on Duet cards:

    My machine will soon have two servomotors in a loop connected to a 1XD daughter board, and I'm wondering if there might be a slight latency between the two 1XD boards (the X-axis and the Y-axis)? Especially in combined movements ...

    In a CAN-connected system, mves are sent to CAN-connected expansion boards a few tens of milliseconds in advance of when they are scheduled to start. A time sync protocol keeps the clocks of all the boards in sync with the main board. So using expansion boards doesn't introduce any differential latency. However, your servomotors may introduce latency.

    @Esteban said in Information on the distribution of calculations on Duet cards:

    Finally, I can't quite figure out who sends the correction command to the motor in the event of an error between the 1XD and the integrated box (for example, with a Cl-42-T box or much more powerful industrial boxes).

    Please explain what you mean by "correction command". It is the job of the servo motor to maintain the correct position. Servos typically have an error output that can be used to signal to the 1XD that they have been unable to maintain position. Such an error can be captured by an event handler in RRF. After fixing whatever caused the error, you would generally need to re-home the axis before continuing.

    BTW when using servos or other external motor controllers to drive the main axes of a machine, we recommend using the Duet 6XD main board instead of 1XD expansion boards because it achieves higher step rates. It also has a more powerful processor than the Duet 3 Mini.

    @Triet Probably easiest just to connect a Klipper-ised RPi to the Duet 2 WiFi, via USB, and install Bossa on the Raspberry Pi. When you want to run Klipper, flash the MCU firmware. When you want to run RRF, flash the Duet 2 with RRF using Bossa and use it in standalone mode. You can probably leave the SD card in the Duet, as the Klipper doesn't use it.

    What limitations are you finding at the moment? The Duet 2 is getting a bit old now, and is limited by the size of the flash memory for all the current RRF features, but generally that's just extra kinematics.

    @dwuk3d Yeahh we use a geared linear actuator. For Z hopping I can see why they might be slow, but we only use them for aligning the IDEX tools, and in the future we indeed want to use them for mesh compensation as well. Both of them don't require high accelerations.

    @dwuk3d said in Sovol SV08 Multiple Motion System Upgrade.:

    Thanks - looks interesting - especially the gearing you have added.

    These spur gears were printed with a resin printer using anycubic's tough resin. They don't last for ages, but I can print a whole bunch at once.
    There are a few user on this board using simpleFOC with it's GCode-compliant step/dir interface.
    It's a bit of a learning curve to get used to it's PID behaviour... Their development & documentation status isn't as professional as Duet3D's, yet.
    In the past, I've tagged some threads with sFOC or simpleFOC if you are interested.

    @guywinslow
    Ok - that's good news but a mystery as to why it did not work the first time, as I assume you, effectively, just reinstalled from github.

    If you had used the version I posted yesterday - there would have been a duetBackup ONLY log created (along with additional debug information) that you could access directly using the DWC UI.

    The version that I sent to you yesterday will be the version posted in github soon. I do not use github for "in progress" builds - just for version bumps, once they are tested.

    While I have tested on my 3.6 beta build - It would be very helpful if you could validate it against your 3.5 build.

    Can you do that for me? I.e. Try the version I posted yesterday.

    P.S. The permissions dsf:dsf from the ls -l look correct - so there may have been some other issue.

    @adrien_tobeca more recent firmware reports the raw angle:

    M591 D0 Duet3D Roto magnetic filament monitor, enabled always, 25.20mm/rev, allow 10% to 190%, check printing moves every 2.0mm, agc 45, raw angle 354, no calibration data

    Also you can use the "S" parameter in M591 to monitor movement all the time if you prefer:

    Sn 0 = disable filament monitoring (default), 1 = enable filament monitoring when printing from SD card, 2 = enable filament monitoring all the time (S2 is supported RRF 3.5.0 and later ). Filament monitors accumulate calibration data (where applicable) even when filament monitoring is disabled

    My vision is almost fully realized! I must have jinxed myself in my last post. No show stoppers, but have hit a couple issues:
    1- you might notice the ethernet jack isn't soldered. It's just dry-fit for show right now. I removed it after realizing that my part didn't match the footprint i used. It was a physical fit, but pins were wrong. I could only find the matching part overseas, so still waiting. I intend to update the schematic/layout to use a more common magjack. In the meantime wireless is working great.
    2- the 12v/24v regulator isn't behaving all the way up to 5A. It's fine up to 3A, but starts cutting out above 4A. I forgot to upgrade the inductor and diode when I moved my target from 3A to 5A. That's probably part of it. I need to take another look at the layout too. Thankfully 5v appears reliable all the way up to 5A. The printer i'm going to test this out on doesn't need the aux supply, so no biggie for now.
    3 - when I added the Molex KK PC style fan header, I mistakenly assumed the Pi5's 4 pin connector followed the same standard. Nope. Easy fix. Happy accident to get to trim the wires down and solder in the correct places. (I guess I could have rearranged the connectors too, but ick)

    Next step is to actually connect to a Duet3 🙂

    @Rat-Rig-CS thanks for your response and for how this had been handled.

    From our side part of the issue was between how warranty issues are handled when a product is supplied from a reseller, vs a board supplied with a complete product (be it a kit or an assembled machine):

    For a reseller supplied product, referral to the forum is the correct procedure. For a product incorporated in kit or complete machine we expect the manufacturer to handle the warranty process (and communicate with us directly, if there is a fault with the board).

    The basic idea being a machine sold as a complete product, which the manufacturer has control over would not be expected to have configuration or wiring issues that we want to debug here on the forum before confirming a hardware fault.

    We will update our T&Cs to make this clearer.

    @chrishamm Thanks! That was it.

    Changed the imports and the send.response() and now it works.

    With hindsight I then find this change (and some others) had been made at https://github.com/Duet3D/dsf-python/blob/v3.6-dev/examples/custom_http_endpoint.py in early December last year, but I had missed that.

    @Aurimas the 1HCLs allow you to use a range of stepper motor + encoders

    Yes you could use servos with integrated drivers and then use a 6XD to drive those 4 motors

    Good evening,

    Would it be possible to operate an extruder in closed loop mode?

    For instance with:

    Duet3D magnetic encoder on the extruder's stepper (commutation) Duet3D magnetic filament monitor near the hotend (close the loop) Duet3D 1HCL

    If this would be possible, it could improve:

    Estep calibration, material independent Retraction Backlash in the bowden tube VFA due to excentric hobs VFA due to speed variations caused by poorly meshed (dual) extruder gears Possibly pressure advance Non linear extrusion Extruder feed forward

    Thanks in advance!

  • Do you have an idea for a cool new feature in Duet Web Control? Post it here!

    @T3P3Tony

    If you go to the General section of the DWC there are a number of options/values that can be set/changed.

    So I was thinking that would be a place to have an "on/off" option that would change the behavior.

    As to M568 - I am using that.

    Here is a the relevant code from one of the filament config files:

    set global.print_beg_tool_temp_a [var.index] = 190 set global.print_beg_tool_temp_s [var.index] = 100 set global.print_beg_tool_ext_adj[var.index] = 100 set global.print_beg_tool_spd_adj[var.index] = 100 set global.print_beg_tool_bby_stp[var.index] = 0 set global.print_beg_tool_prime [var.index] = 10 set global.print_beg_tool_retract[var.index] = 0.5 set global.print_end_tool_retract[var.index] = 0.5 set global.print_beg_bed_temp_a [var.index] = 60 set global.print_beg_bed_temp_s [var.index] = 30

    Later on there is this code in another routine that applies these values:

    ; this part is just to make the use of these values down below a bit easier to read by using shorter names var bed_temp_a = global.print_beg_bed_temp_a [var.tool] var bed_temp_s = global.print_beg_bed_temp_s [var.tool] var tool_temp_a = global.print_beg_tool_temp_a [var.tool] var tool_temp_s = global.print_beg_tool_temp_s [var.tool] var ext_adj = global.print_beg_tool_ext_adj[var.tool] var spd_adj = global.print_beg_tool_spd_adj[var.tool] var bby_stp = global.print_beg_tool_bby_stp[var.tool] M568 P{var.tool} S{var.tool_temp_a} R{var.tool_temp_s} ; set extruder heater temps (active and standby) M221 D{var.tool} S{var.ext_adj} ; set extruder extrusion percentage adjust M140 S{var.bed_temp_a} R{var.bed_temp_s} ; set bed heater temps (active and standby) M220 S{var.spd_adj} ; set print speed adjust M290 R0 S{var.bby_stp} ; set initial baby steps
