Inconsistent delays during homing and other movements

Gimme a minute to digest that.

I should mention it's not just homing. That's just the obvious example. Manual moves after a successful homing also tend to have random ~20sec delays before execution. The first few times it happened I thought it didn't register the click and I'd click the button again... so the commands would end up getting queued up and execute over time.

Phaedrux

Other than calling a lot of nested macros I can't see anything obvious that should cause those delays.

You may want to try the latest firmware beta. https://forum.duet3d.com/topic/6070/new-firmware-2-01-beta-2-available

Phaedrux

@synfinatic Are those clicks in the DWC or on the PanelDue? What version of DWC are you running? Try the new firmware beta 2 along with the DWC beta 2 from the same download link.

synfinatic

I have been testing via the webUI. I've upgraded the firmware and webcontrol files to the latest beta. Started the full homing (via web) and X & Y seemed to work fine. But it never dropped the gantry to home Z and then gave up. The console has the error:

Error: Z probe was not triggered during probing move

Which is accurate.

Rebooted the whole printer and started homing via the PanelDue. That worked perfectly. Moved it around in X, Y, Z, no problems. Re-homed a few more times (still using the PanelDue) and it worked great.

So then started using the WebUI again. Did a full home- worked fine. Tried moving in X and it moved in X and Y. Went back to the PanelDue and verified that DOES NOT happen when moving via the PanelDue. Did more moves via the webUI and seems like any X or Y moves diagonally in both X and Y. If I didn't know better I'd say my CoreXY printer was setup wrong, but this is only happening via the webui.

Update: I should mention that it doesn't move in X and Y when homing X or Y. It only does that during moves post-homing.

Phaedrux

Can you confirm you are using this version of the DWC?

https://github.com/dc42/RepRapFirmware/releases/download/2.01beta2/DuetWebControl-1.21.2-b2.zip

synfinatic

Yeah, I uploaded the b2 DWC zip file via the UI after upgrading the firmware.

So I downgraded back to the release version and moving via the web (after homing via paneldue) only moves in a single axis at a time, but there's about a 5sec delay before executing the move. No delay with the paneldue.

I also tried re-homing via DWC, and it's slooooowwwwww again.

Phaedrux

Hopefully from the information we've gathered someone will have a better idea of what might be going on.

BTW, have you printed anything yet? Does it execute a print properly?

synfinatic

Back to beta2 firmware and DWC.

Behaving the same as I described before with this version. The only additional info I can provide is I notice when doing a moves, they're not just running at angles, but reversed on the selected axis. Basically -100 Y causes the head to move +50Y and -50X. Same pattern for X moves. The head position values in the upper right corner of the DWC update correctly based on the physical movement of the head.

Phaedrux

If you manually go through the movement testing section for coreXY do you get the movements you expect?

https://duet3d.dozuki.com/Wiki/ConfiguringRepRapFirmwareCoreXYPrinter#Section_Movement_section

synfinatic

@phaedrux Nope. Just finished wiring and slowly bringing the printer to life. Was acting so wonky I haven't even gotten to the gantry leveling step or even tried the extruder.

Honestly, until upgrading to beta2 I was pretty much convinced my board was bad and I needed to RMA it with Filastruder. But b2 seems like an improvement (at least it seems more consistent) so not sure anymore

synfinatic

@phaedrux It was fine under 2.0 and is fine under 2.01.beta2 via the PanelDue. Only has issues under 2.01beta2 via the DWC.

BTW, thanks for the help. Feel like we made some progress. Hopefully someone else can provide some ideas.

Phaedrux

Have you been able to get any feedback from the creators of the config set?

synfinatic

I've been talking to a few other people with the same printer using the same config. Nobody has seen anything like this. They were thinking I had a bad board.

Ran M122 again, just for comparison:

Phaedrux

@synfinatic said in Inconsistent delays during homing and other movements:

=== Expansion ===
DueX I2C errors 6830

No idea if this is relevant or not. I thought so more before when I thought it was just the Z axis pausing during homing because all the Z motors are on the Duex, but if it's pausing in all axis that seems like a contraindication.

Do the other users you've talked to get similar errors?

dc42

As I mentioned in the release notes, I believe there is a problem with DWC 1.21.2b2 on CoreXY machines. I suggest you use DWC 1.21 for now.

synfinatic

Is DWC 1.21 compatible with the latest beta firmware?

Edit: release notes seem to indicate it is if I'm not using a password? Gonna give that a try. Still would love to understand why I'm seeing these delays with the stable release and nobody else running a Duet on the Voron2 is. Of course, it's a pretty small sample size right now.

synfinatic

So trying that combo, and power cycled the printer (no USB connection) to start from a baseline.

From DWC:
First "home all" went perfectly
Second "home all" started fine... X & Y homed normally. Then things started to slow down after the first Z touch off
Third "home all" and there's a ~20 sec delay before each movement, starting immediately from pressing the button in DWC.

Tried home all from the paneldue immediately after the 3rd and it had the same problem.

Rebooted printer again.

From PanelDue:
Ran "home all" 3 times, all behaved correctly

Tried home all from DWC immediately after the 3rd paneldue test and it worked correctly three times in a row.

Then did a bunch of x/y/z moves via DWC. Not only did they move in the correct direction, but they were quick & responsive.

So it seems that as long as I do the homing first via the PanelDue then things are ok. But initial homing via DWC == problems.

Update: edited my config.g (reduced Z travel max) and reloaded. Then tried to re-home via the PanelDue which was immediately buggy. So it really really wants to start off from a hard reset.

synfinatic

So been playing with the printer most of the day. In general this combo seems to work better, but I'm not at the point of it being fixed. From a fresh power cycle, homing via the PanelDue works most of the time, but not always. Executing more complicated actions like gantry/Z leveling (auto level) and mesh leveling sometimes works, sometimes doesn't. Haven't been able to complete a full leveling cycle yet without things starting to start showing the 20sec delay between moves I've mentioned earlier.

Haven't gotten things reliable enough to start tuning the extruder or even trying to attempt a print.

Honestly, the fact that sometimes it works and sometimes it doesn't, even though the config/macros don't change seems to indicate some kind of firmware/hardware issue. I've re-flashed the firmware probably half a dozen times now, so maybe it's hardware? Not sure what else to do other then to RMA the board unless someone has a better idea?

dc42

Can you confirm that you have a very short and thick wire connected directly between the ground sides of the VIN terminals of the Duet and the DueX5, as per the DueX5 installation instructions; and that those terminal block screws are tight?
