Thanky @chrishamm!
It works great now!!!

I'm running 3.3b1 on 6HC+SBC+3HC. Testing 2 motors on X and 2 on Y, each on a board:
M584 X0.1:1.1 Y0.0:1.0 Z0.4:0.3:0.5 E1.2 U0.2

Wile printing I got a skipped step on XY that I belive is from CAN communication.
Paused the print and took out the diagnostics.
Then Homed X, Y and canceled the print.
When issuing M122 again, the ticker of CAN messages was reset.

CAN messages queued 93948, send timeouts 11, received 149541, lost 0, free buffers 36, min 36, error reg 110000
CAN messages queued 12504, send timeouts 0, received 9388, lost 0, free buffers 36, min 36, error reg 0

Messages queued 149589, send timeouts 749, received 94000, lost 0, longest wait 20ms for reply type 6024, peak Tx sync delay 493, free buffers 49 (min 37)
Messages queued 9270, send timeouts 0, received 12324, lost 0, longest wait 1ms for reply type 6037, peak Tx sync delay 493, free buffers 49 (min 48)

Do I have even higher timeouts throughout a print that do not show up?
What can I do to make communications more stable to be able to use all steppers?

Printing paused at X264.7 Y302.5 Z3.2 U102.1

I confirm this is fixed in 3.3RC3.

I'm running on duet wifi 1.03 and 2.02RC2(RTOS) (2018-09-07b2).
Typing 'M915 E' returns truncated response, same as 'M915'. Is that normal?

@Red-Sand-Robot
Beautiful build! A lot like how I want to do it.
I was thinking of calibrating the steps per unit of the X axis in regards to Y to get it completely square.
Because when moving Y axis you need X axis to be stationary but X stepper has to move with it, needing belts and such to be perfectly equal.
I use this calibration cross to check on my CoreXY:

@deckingman I really do love the idea and the results! (That's my printer)

@chrishamm Upgraded to ” RepRapFirmware for Duet 3 MB6HC version 3.2-beta3+3-ch running on Duet 3 MB6HC v0.6 or 1.0 (SBC mode)” and looks like it fixed both the missed stepps and the stuttering.

Ran the macro above and runs well even at 500mm/s.

Doing a multitool testprint now.

@dc42 said in stop.g using conditional G code:

if state.currentTool >= 0
  if #tools[state.currentTool].heaters > 0 & heat.heaters[tools[state.currentTool].heaters[0]].current > heat.coldRetractTemperature
    G1 E-2 F300

Just for information if anyone else pulls his/hers hair out wondering why it doesn't work.
This will not work if the tool has 0 heaters because the whole second statemet is evaluated and an error is thrown.
This works instead:

if state.currentTool >= 0
 if #tools[state.currentTool].heaters > 0
   if heat.heaters[tools[state.currentTool].heaters[0]].current > heat.coldRetractTemperature
     G1 E-2 F300

Tested with RRF 3.4b6 on Duet3 6HC whithout SBC.

@chrishamm Thank you!
Please also note that the log level of S1 and S2 are reversed to what is stated in Gcode documentation.

Hi!

Upgraded my Duet 2 WiFi from a older 3.4 beta to latest and greatest today.
After uploading a file, be it in DWC or trough PrusaSlicer, it doesn't show up in the job list and when refreshing I get the error:

Not sure if it's DWC or where this comes from. After waiting a while, refreshing works again.

Hi!
I have a genuine but old Duet 2 Wi-Fi v1.03 that is not booting anymore.
I haven't used this printer in a while but decided to start using it again today.
When homing Z with the Precision Piezo Orion probe, the printer died. Before starting the print I tested the Z-probe, by taping on it and tested the heaters and steppers.

It restarted and I checked the logs but could not see anything more than that it had booted today and no errors, last boot before today was 9 months ago according to the log.

I tried to print again, and it died once more but doesn't boot up anymore.

The 3v led is not powering on. So, after some searching here, I disconnected all connectors, the DueX board and the SD card and tried powering by USB.

The u2 3v regulator gets hot but nothing else, not the SD, Wi-Fi or processor.

My electronics knowledge is close to none so my question is if it would be enough to change the regulator (have to find and pay someone) or if I should just "recycle" the board.

@dc42 Thank you! That did it!

In the object model there is a sensors.probes[n].offsets[2] that is set to -0.7 for both my P8 probes.
This is not the trigger height, that is 0.
I do setup my probe with G31 Z0.
Where does this offset come from and what is it?

Hello!

I run a toolchanger with only different colors of PLA right now.
For a small object the tool can be in action for just a couple of seconds for maybe a couple of layers and then change back to the other one and in between maybe not used for a 10 minutes.

Is there a way to delay putting the tool in Standby temperature for like 15 seconds from it being deactivated?

Using e3d Revo betas and heat up times are fast but so are the cooldown times.

I was thinking of using global variables and daemon.g but it might be overcomplicating things.

@t3p3tony Thank you! This looks much better!

@t3p3tony Forgot about it, have it in a macro:

M955 P0 C"0.spi.cs2+0.spi.cs3" I41

Hi!
I’m building a printer, CoreXY toolchanger, 500x500x600 build area.
When Irun the accelerometer on the carriage I get very hight response at very low frequency. Around 0.7 and 2Hz regardless of M201 setting, regardless of whether I tighten or loosen my belts.

Now using 3.4b6 but same problem since I got the accelerometer when this was first introduced.

My speed settings for XY:
M556 50
M203 33900 (reaching 500mm/s when collecting accelerometer data)
M201 5000
M204 5000

Collecting after 4s wait with:
M955 P0 C"0.spi.cs2+0.spi.cs3" I41
M956 P0 S1000 A0 G4 P10 G1 X100 F30000

!

I’ve been having this issue since the beginning and I now thaught that I’d ask for help.

This are some imaages of the printer if it helps:

Also, my config files are at: https://github.com/TypQxQ/DuetBackup/tree/main/qTC-backup

Thank you for looking at this.

@t3p3tony Thankyou, I missed that when checking the code for it....

[My fault, see below.]
I read that the b6 has a new toolchange behaviour: Important! After changing tool, RRF no longer moves the new tool head to the coordinates at which the old tool head was at when the Tn command was actioned.

But my toolchanges have not changed, the new tool still goes back to where the old one was.
Am I missing something?

All my config files and logs are updated at: https://github.com/TypQxQ/DuetBackup
