I have seen that, we are a bunch of mechanical oriented guys in our group, so programming is taking us quite a while, so much different then C that I used to use.

RE: RRF3.2 request to enable G43 & G44 Tool height offset
RE: RRF3.2 request to enable G43 & G44 Tool height offset
Guys this seems to be a great work around for the limitation on variables, as from what I can tell you are using the work offsets of non used coordinate systems to store the values from your probing, and then performing the math on them to get the result you desire.
The only syntax that I am having a hard time following is where do the "move.axes.machinePosition" and "move.axes.workplaceOffsets" come from. I assume they are calling something at the firmware level, but it seems documentation on this is limited.
I have seen other threads where people are using these meta commands, but finding documentation on them is rather limited. I've gone so far as to dig into linuxCNC as it appears some of this work is derived from there. Any suggestions on where to learn more on the meta command structure would be greatly appreciated.
External 5V for 3HC
I recently implemented external 5V power to the 6HC mainboard in our machine, this is inorder to use an emergency stop circuit that cuts power to the motor drivers only, while leaving the logic side up. While performing this operation I forgot about the 3 3HC boards we also have in our system.
Presently they are not connected to any motors we are only using them as inputs.
Is there a way to also provide external 5V to the 3HC boards?
Strange behavior when tool changing in different machine modes
A colleague and I are building a machine that uses a process of depositing and then milling away material sequentially. As a result we have used the commands to change machine mode when we switch between extruding and milling. In CNC mode the machine behaves as expected. The tools park and take their positions from the tpreN.g command.
When we are in FFF mode, the tools follow the tpre and get their parked positioning but then they move their z and update position as well, to the last Z position before tool change.
While I can see this as being beneficial to a traditional IDEX or tool changer, there is no documentation as to what's going on behind the scenes with the mode switch. As far as I can tell the mode switch appears to only be changing the DWC interface. But from the differences in behavior we are seeing there appears to be more going on.
Since this is an R and D project we appreciate being able to use the FFF interface to manipulate the Extrusion Factor on the fly (we are not using filament).
The same goes for when we are using our mill we like the ability to manipulate spindle speed while it is operating as we are still determining optimal values for our process.
We also use the same gcode file for printing and milling, as it's a sequential operation. This allows us to preserve our working zero without having to reprobe our parts between operations.

This might make it a bit easier to read, just imbedded your code

RE: how not to turn off Duet?
@engikeneer using the PS_ON configuration sounds like a more "typical" e-stop style setup. Quick question, how are you supplying the separate 5V for the board?
The only documentation I can find on this is supplying 5V to the board thru the SBC, is this how you are running or are you using some other means of input?
RE: Network disconnects when I attempt to start a gcode file
@Phaedrux Thank you for your help, it was the firmware. I had to use the Bossa method with the usb connected from the Duet to the PI
RE: Network disconnects when I attempt to start a gcode file
The Pi is powered thru the ribbon cable.
I'm unable to SSH into the PI right now, so I'm wondering if that could be the issue
M98 P"config.g" when executed I get
Error: Macro file config-override.g not found
Network disconnects when I attempt to start a gcode file
I have a Duet3 that is setup as an IDEX stye unit with one X gantry but two independant Z carriages. It is connected thru a raspberry pi 4.
We are at the stage that we have setup our homing config and everything seems fine, we have verified all our steps, and we have communication from the web interface with no issue.
When ever we attempt to initiate a file we get network disconnect and then "Operation failed (Reason: Cannot assign requested address /var/run/dsf/dcs.sock)".
It then reconnects, though sometimes when it reconnects it has lost its config.
I'm at a loss of where to even begin trouble shooting this.
