@Phaedrux a quick update, I commented out the T-1 at the beginning of my t0pre.g that I added in, and it is now working. I guess that is causing confusion in the printer, just added it in for safety and forgot about it. Problem solved!

Hello,

I recently found that input shaping is not available on expansion boards and was shocked. I've been thinking about using closed-loop for XY on a printer (mostly because why not? I love the idea of closed-loop).

Is there a timeline for adding this functionality? Also curious what is the thing preventing input-shaping from being available on expansion boards from a software standpoint.

Thanks!

Hello,

I am attempting to query the machinePosition of one of my axes, specifically axis 7 (Duet 2 Wifi + Duet X5) on an E3D Toolchanger. This is the toolhead axis, C, that locks and unlocks tools; it is set to driver 7 in the config.

M584 X0 Y1 Z2 C7 E3:4:5:6 									; Apply custom drive mapping

However when querying the position using

move.axes[7].machinePosition

The following error appears:

M98 P"0:/macros/SIMUL_HOME_TEST"
Error: in file macro line 49 column 4: meta command: array index out of bounds.

Is there a specific indexing for the Duet X5 drivers?

Hello,

I've been setting up some tools on my Toolchanger and tuning the offsets (especially if you're changing nozzles often) can be a pain. The values are close but require baby-stepping to tune perfectly.

It would be nice to have a "Save Tool Offset" button under Z-Babystepping that would change the G10 tool offsets in Z in config.g (or perhaps have another parameter to specify a system file or macro that contains the offsets). It would then set the Babystepping value to zero so the Babystepping value wouldn't affect other tools.

Thoughts?

Hello,

I know there is a boolean variable for each axis to determine if it has been homed or not, just cannot find the syntax after searching online.

Something like axis[n].homed (for n being a integer indexed at 0) or similar.

Trying to make simultaneous axes homing for completely independent axes on an E3D Toolchanger (toolhead and XY) which i think requires conditional statements as something like:

G1 H1 Y-400 C-500 F5000			; SIMULTANEOUS HOME Y AND C

terminates the homing movement program as soon as one axis homes (both use stall detection). Therefore I think conditional if/else statements need to be used.

Ex
if (y is homed){
continue homing C
begin homing X
}

else {
continue homing Y and run macro to return C to unlocked position (not sure if this can be done simultaneously)
}

I realize the time to home is much much smaller than the time to heat up the printer but still thought it would be fun to optimize a bit.

@T3P3Tony this is for the case where I'm waiting for the actual hotend that is going to be used. For instance if I'm just using T0 for the print (no toolchanging).

1. T0 starts at 250C as I just finished a print, or had to stop it for some reason, whatever it is--the tool is hot.
2. Start code waits for T0 to reach 180C, which is it's standby temperature (as well as other hotends if used, and bed).
3. Homing
4. Toolhead goes to pickup T0
5. Printer waits for T0 to heat back up to 250C

It would be nice if it was possible to recognize if the tool was already at or above the standby temperature so it didn't wait to cooldown just to heat back up again.

I'm going to try using conditional gcode for this, but it would be nice if it was just an alternative parameter in the M116 gcode.

Hello,

Suddenly my Toolchanger is not recognizing T-1 commands, and is not applying tool offsets.

I can home, and pickup a tool, the dashboard shows the tool as active, however once picked up the offsets have not applied (including Z-offset, rip my bed) and I cannot rehome the tool via T-1.

Running Duet 2 Wifi + DueX, firmware 3.4.5. It was working an hour ago, now nothing. I have tried restarting (via both E-stop and actual power cycling), the problem persists.

The only thing I've changed was the sensitivity of my stall detection in my homing files. Send help.

Hello,

I wanted to set my M915 stall detection parameters in a single place - config.g, however, running a CoreXY machine, both X and Y motors are involved in any linear move along a single axis. It turns out that the settings despite setting axes are applied to the X and Y driver and do not update to apply to both when homing.

The detection parameters would ideally look something like:
M915 H200 X S1 R0 F0
M915 H200 Y S3 R0 F0

To fix the I would need to put M915 commands in each of the homing files (homex.g, homey.g) as well as homeall.g, they need to combine both X and Y and look like:

M915 H200 X Y S3 R0 F0

It would be nice to be able to set the M915 parameter in a single place such as config.g and have it update both drives when calling a G28 command (whether G28 X, G28 Y, or simply G28) to whatever value as it's easy to forget updating one of the files if changing/tuning the stall detection. A way to implement would be simply calling M915 with a specified axis and it would update the drivers to use the sensitivity set in the config.g.

ie M915 X (would update both drivers to the set sensitivity in config.g).

Hello,

Running a toolchanger I sometimes have to update values of a specific tool. Most recently I was calibrating E-steps of one of my tools and couldn't find a way to update the value in the console without including all the values. I was updating the values for tool 1 which is the second number in the series.

Ex. M92 E400:405:400:400

Is there a way to do something like M92:405:: or similar to only update one value in the series?

@Phaedrux I will experiment with it. I've never used it before though, can it support different retractions for different tools?

Also, can it be adjusted by the slicer based on the filament profile (if it requires more/less or faster/slower retractions)?

@Phaedrux slicer retraction.

@OwenD I'm not sure if putting it in the start code will help. I want the process to look like the following:

Prime nozzle -> retract -> move to print starting coordinates -> deretract -> start the print.

The start gcode ends after the retract stage.

@Phaedrux it is an actual retraction, I do a prime, then retract for the move to the printing start point, however, the slicer doesn't have the retract undone before the actual print starts.

Hello,

The E3D Toolchanger uses three macros for toolchanges, the tfreex.g, tpostx.g, and tprex.g. In which I have retractions, extrudes (undoing retractions), and other macros, such as initial purge, retract, and brush.

I'd like to keep these macros as they work well but I notice that the start of my print usually has a few mm before any plastic is extruded because of the retraction at the end of the tool picking so the hotend doesn't ooze anything on it's travel between the brushing area and the start of the print. Is there a way to get the printer (or slicer to have the printer) undo that final retraction and then actually start printing?

I'm not sure if this was a question for Duet or PrusaSlicer so I'm posting in both.

Thanks!
