I have a voron 2.1 printer that has been working fine till this morning. I may have changed something in some config.... dont think I did but throwing it out there lol. I have 3 macros to setup Z probing. One for inductive homing fast to get a rough Z=0 and then a inductive homing slow when doing G32, bed leveling. After bed leveling x and y are homed again, and the Z probe is switched to an FSR for the nozzle to tap. All works really good until now. For some reason when using G32, both the first fast inductive home and slow inductive home at 0,0 (bed center) work fine, but something happens on the first G30 command to probe the front left of the bed. Below is the G30 sequence i use.

G30 P0 X-125 Y-125 Z-99999 H+0.00
G30 P1 X-125 Y+100 Z-99999 H+0.00
G30 P2 X+125 Y+100 Z-99999 H+0.00
G30 P3 X+125 Y-125 Z-99999 H+0.00 S4

I tried performing the steps using the console to trace where the issue is. It seems like the first line
G30 P0 X-125 Y-125 Z-99999 H+0.00

I also noticed that along the Y axis once I get close the the limits of travel, with 0,0 being bed center the Z probe trigger value hits 1000. I think this is where the Z probe already triggered is coming from but why? I checked all the wiring and all is good.

BTW using 2.03 latest. Any ideas?

Hey @dc42 , I have a Duet 2 Ethernet, latest revision with the latest firmware (issue has been observed with past versions of firmware and DWC as well) that will cause DWC/Duet 2 to disconnect every time when running a test gcode job and will not reconnect until I power cycle the Duet 2. Since I am still doing the last bit of testing/commissioning, my test gcode is of a random object with gcode generated from Cura 4.0 (also happens with Simplify3D) but since my hot end and bed heater are not connected i remove the lines that start the heaters to the required temp in a text editor and then save it, upload and run the job. About a few minutes into the test print is when the disconnect happens. I do get the error about attempting to extrude with no tool connected for almost exactly 4 minutes until I get a warning "Connection interrupted, attempting to reconnect... Request failed with status code 503". It may also be worth noting that although the board is a Duet 2 Ethernet, I do use a raspberry pi 3b to act as a bridge between a usb wireless card and the ethernet port and then to the Duet 2 Ethernet. Personally it doesn't seem like a big deal, never had the issue on my other Duet 2 Ethernet or Wifi when printing a normal print but just want to bring it up in case the underlying cause can cause issues somewhere else, for someone else. Let me know if there is any other information I can provide.

Thanks for the information. Time to re-wire lol.... i hate wiring but a good job is very satisfying.

Im building my printer and had the basics wired to check it all out, XY steppers and XY endstops. Everything worked fine but after I wired everything up in a nice wire loom/harness only the X axis homes correctly. The Y axis acts as if wherever it is at triggers the switch and sets that as the origin. My endstops are NC so when not switched the LEDs are on. I verified they work and when switched the LED goes off. Is it possible that I am getting interference or something from the stepper motors now that I have everything in a single wire loom instead of loose when testing it?

So i think it had something to do with how I was testing the printer. I created a macro that was a snippet of a full gcode file. I have been messing with it for the last hour and as soon as I let it run the macro is when I get disconnected.

I dont think that may be it. I have it setup on a static IP. This morning I gave it a try and it connected fine. Not sure what the issue was/is...

Tonight all of the sudden I lost connection with my Duet 2 Ethernet. Whenever I try to reconnect I get the red CORS Request box and then another red box that says Cannot read property of 'fanRPM' of undefined. @chrishamm any tips?

I found the culprit.... and it seems to cause RRF to glitch. It had to due with my axis min and max in the follow gcode:

M208 X-175 Y150 Z0 S1 ; Set axis min (X350/Y300/Z300)
M208 X175 Y-150 Z300 S0 ; Set axis max (X350/Y300/Z300)

You can see the my min and max Y are reversed. I noticed that when I moved the Z axis and the XY motors moved the Y coordinate would with be 150 or -150, no values in between, @dc42 could there be a checked implemented for this?

I figured out the reason my one Z was not moving the same distance as the other 3... wrong GT2 tooth count lol. If i start the printer from a fresh power up and send G92 X0 Y0 Z0 so it thinks XYZ are homed at 0,0,0 and command a Z movement both the XY motors move. Not sure if their direction is correct as I dont have my X gantry on. If from a fresh power up i send M564 H0 and move the Z axis, it moves correctly and the XY steppers do not move.

" I command Z+5 move, three of the screws move 5mm, one screw moves 2.3mm" is what happens. Its belt driven on the Z but mechanically and belt tension look ok.

I just tried using M584 H0 and then tried some moves... what do you know the XY steppers dont move. Why is that? I tried it with another config.g that is very close to what I have... mostly just format changes and it worked when entering G92 X0 Y0 Z50 and then requested movement.

I also noticed that I had driver 2 (the dual Z stepper output on the Duet 2 defined as extruder 3
M584 X0 Y1 Z5:6:7:8 E3:4:2 ; Set Drive Mapping

so i changed it to this
M584 X0 Y1 Z5:6:7:8 E3:4 ; Set Drive Mapping

If I unplug the XY steppers and only request a Z axis movement I get an error about drivers 0 and 1 not being connected properly. Seems like somewhere something is messing up the axis assignment? Also even thought the X and Y move when the Z does, it seems like the Z axis raised/lowers by different amounts which makes me think that the steps/mm are also incorrect somehow.

Hey @nhof All movements are being requested through DWC2. If i try to move the XY axis individually they move fine. Its when i request any Z movement on DWC2 that the XY steppers move as well.

I have a CoreXY build i am working on with a Duet 2 ethernet and Duex 5 on latest firmware. I have it setup far enough along to where I can start figuring out my wiring. I have the 4 Z steppers, the 2 A/B motors for XY and 1 extruder currently plugged in and to the best of my knowledge configured properly. When I give it G92 X0 Y0 Z0 just so i can test it (No homing switches yet) the A/B motors for the XY axis move when I only command the Z axis to move. A/B (or XY) and E0 steppers are plugged into the Duet 2 just as they are labeled on the board. the 4 Z steppers are on the Duex5 on 5-9 as labeled on the board as well.

Here is my drive mapping
M584 X0 Y1 Z5:6:7:8 E3:4:2 ; Set Drive Mapping

and the gcode to set it as corexy movement
M667 S1 ; Select CoreXY mode

Thanks for any advice!

Are you resetting baby stepping after each print? Also I thought i remember sometime ago that when you measured your Z offset, it would conflict with your old offset as well so you had to send a G code to basically tell it there was no offset. I think this has been fixed but maybe @dc42 can chime in?

good point... I would really like to get a filament sensor. It seems like the magnetic version worked a lot better from what i remember reading however i guess its the laser version that is only available. I have some time to tinker between my current build. I haven't read this whole thread but do we think we can get it to work reliably with some community effort? If so I'll place an order to buy one. My current build has the extruder temporarily mounted on the outside and is wired up and already calibrated so seems like a good time to help? Would be nice if I could contribute to the community after lurking for so long...

I am wiring up my Voron 2.1 build and am still a bit lost on how everything is setup. Using a BLtouch to level the 4 Z steppers using the mesh compensation to make the gantry level with the bed and then a FSR for the Z offset. I assume the the FSR (using the John SL board) would go just as the Wiki says "If using JohnSL's trinket board: Connect its Vcc, Output and Ground pins to 3.3V, IN and GND on the Z-probe connector respectively and select mode 5." Connecting the BLtouch i also assume would be like i currently have on another printer, free up a heater channel for the PWM and supply but after that I am not sure how it is all configured. I have a sample setup from DavidMX but he is using an inductive probe. Any tips would be appreciated!

What about some knock off Bondtech gears?

would lightly sanding the bearing also help with the sensor pickup more light?

Where did you get those values? I dont remember what each parameter is for but here is mine, Stock duplicator 6 bed and an E3D Chimera, all 24v. Hope it helps.

@chrishamm I am really liking the updated DWC! This may be a dumb question but since you are starting a new DWC as a foundation for the future, would drag and drop/re-sizable windows ever be possible? This way anyone can set it up the way they like? Thanks for all your hard work!
