The page here: https://docs.duet3d.com/User_manual/Tuning/Input_shaping_plugin
The link to the Input Shaping plugin points to an older, beta release rather than the current release. This generates a 404.
It points to: https://github.com/Duet3D/DSF-Plugins/tree/dev/InputShaping and https://github.com/Duet3D/DSF-Plugins/releases/download/v3.4.0/InputShaping-3.4.0-b1.zip
Ideally it should point to: https://github.com/Duet3D/DSF-Plugins/releases/ so any new releases are automatically linked to.
@oliof Right. Could be. I'm going to have to go back to basics and tune it all from scratch, ignoring the numbers that the Orbiter reckons are right.
Thanks for that.
OK, last night I changed it to 1000mm/min for jerk and other than my print time dropping drastically and my accelerations looking like they did before, I couldn't see anything bad as far as print quality is concerned. That was printing at 120mm/sec. No funny noises from the extruder either.
Hi all
I've recently changed my extruder on my large CoreXY from a BMG to an LDO Orbiter. So far so good except my acceleration is now being limited by pressure advance and extruder jerk.
The recommended value for jerk for the Orbiter 1.5 is 300mm/min which is really low. With the BMG I was running over 1500.
My PA is set to 0.055 which is pretty close to where it was with the BMG (0.06).
My question is, does anyone have experience with this extruder and setting jerk values above the recommended?
I see there is a new version 2.0 out that pushes this up to 600mm/min but I can't for the life of me find any information on why the 2.0 can have higher jerk than the 1.5 when the motors are largely identical and the gear ratio is roughly the same too.
@dc42 Yes, it's essentially a switch wired to an endstop.
Will look at G30 but I'm guessing that I need to run the G30 on my first tool before probing the XYZ=0 of the stock.
Thanks. Will have a play later.
Hi all
I'm using a Duet2 to drive a small CNC machine (PrintNC) and everything is good. I'm looking to make toolchanges easier and so have added a toolsetter. This is alongside my current XYZ work 0 finder.
I'm struggling to get my head around how to make a macro that will update tool lengths.
My Z homes to Z max
Ideally my workflow will be this:
Home machine
Jog machine above XYZ probe
Run my XYZ find 0 macro - which works fine and sets work 0 in WCS G54 system 1
Run tool length macro which does the following:
Move machine to the tool setter
Probe against the tool setter to establish my baseline tool length - which I'm assuming will be 0 offset for the first tool
Do some cutting
Tool change
Probe against the tool setter with the new tool to establish the delta between my original tool length and this new tool
Apply offset to WCS so that Z=0 is in the same place as it was initially
Any help greatly appreciated.
I'm running a CNC with Nema23s from a DuetWifi. It works well. I've got my drivers set to 2.3A and am using active cooling with heatsinks on the chips. I've not noticed any issues after 100s of hours of milling.
@hagrid @chimaeragh Completely forgot to post the macros.

@hagrid I've made some macros to deal with the xyz probe. Just need to edit for your different tool widths. I mainly use 6mm and 3mm end-mills so this works fine for me at the moment to have 2 macros. If I have an oddball sized bit then it's only 10 seconds to adjust the macro.
Admittedly, it would be lovely to have the Workbee style probe as a plugin but for the minute, the benefits of the newer firmware and this DWC outweigh the loss of the probe functions.
If you want me to post the macros I can do so tomorrow when I'm in the workshop.
@cncmodeller I'm using a seperate Arduino to drive the backlight. Works fine.
Design here: https://www.thingiverse.com/thing:4812429
I've included STEP files.
@chimaeragh Yes, on both counts.
@weed2all I'll be sharing the files today on Thingiverse. Will post back here once uploaded.
I set up a CNC pendant using DC42's excellent sketch. I felt it was missing something though.
With the support for 12864 displays for DuetWifis being added in 3.2 I set about a modification to the design.
Luckily there are enough wires in the stock CNC pendant cable to support this so I just needed to make a small loom using some breadboard at both ends.
Works like a charm
Made some hangers for it:
Hi all
I’m pretty sure the answer to this is “no”, but is there any way to get a 12864 display configured to show machine coordinates as well as user/work coordinates?
I’m setting a 12864 up on a CNC and I can get the menu config in DWC to show user coordinates just fine on the display, however it is sometimes useful to know the absolute machine coordinates too.
@droftarts I'm using a Duet2Wifi and M150 results in a Command not supported error. This is with 3.2.2
OK, I got it working apart from the backlight. I'm guessing that the DuetWifi doesn't support the NEOPixel RGB. We have a connection for it though in the pinout for connecting the Mini 12864.
I’m going to be setting up one of the Fysetc displays with a Duet WiFi tomorrow. Thanks for the wiring layout.
If I only want display but don’t care about the SD cars I’m assuming I can do without some of the connections. Or are the all required?
Thanks. I thought it might be.
I'll have a go at replacing it. I've replaced the board so might as well have a go and see if I can resurrect this one.
Entirely my own fault as I had a wiring fault that dumped all of the ground main power out of the ground from the expansion connector.
The board still works but I cannot connect via PanelDue or any other serial device. USB works as does WiFi. I can't see any damage on the board but could do with a pointer as to what component might have failed so I can have a pop at replacing it. Any thoughts from those who know the schematic of these boards?
That's great. Thanks for your efforts with this.
