I'm running a test print and pause/resume is working correctly now. That was the problem. Replacing the G1 R1 in resume.g with G1 R1 X0 Y0 Z0 fixed the problem. Thanks Dave!

Yes, I see exactly what you are saying and no I hadn't updated my resume.g file to reflect the new G1 command. It still did not specify the X, Y, and Z axises. I have updated it now and we'll see how it goes.

No tool Z offset. I do use babystepping. Here's my config:

I am running 1.20RC3 of DuetWiFi firmware and RC3 of DWC along with latest of WiFiServer.bin. When I Pause and then Resume, the print head resumes a layer or two higher than where it was paused. Subsequent pause/resumes lift the head higher. I repeated this several times and it happens under 1.20RC2 and 1.20RC3.

Checked after power cycle, printer appears to be functioning again. I did do a M502 and M500 after upgrade that might have done something to create the issue.

I upgraded to 1.20RC3 this morning and tool changes on my mixing delta no longer function. Selecting any of the tools in DWC produces a "Attempting to extrude without having a tool selected error". I heard the extruder motors making strange noises and I shut the printer off and on before the hot end was jammed badly. I had this bug occur a while back in a previous build. It caused a great deal of havoc to my hot end.

Pause print and resume failed for me from the PanelDue. The hot end resumed extruding a couple layers above the print. Running 1.20RC2 and latest DWC release candidate,

Layer shifting and extruder issues are fixed here! I did have to take apart my diamond hot end to unclog two of the filament chambers due to extruder issues in the previous beta. But, hey, we're off and running again!

@Forgvn77:

I tried the DropBox version. Unfortunately I wasn't able to determine if a layer shift problem exists because the extruders were not extruding correctly. I had defined and selected an equal mix (Tool 3) of four defined tools and three physical extruders. The first of the three extruders was the only one feeding filament. I selected another tool to see if the problem could resolve itself and I received an error in DWC "Trying to extrude without a tool selected." This has not happened before.

I just tried this on my machine with 1.20 beta8 (not the dropbox version) and all extruders/tools work as expected.

Yes, that's right. Previous versions have not done this. The previous beta's issue was not with the extruder, but the layer shift.

I also have experienced layer "skewing" with 1.20beta10. Printed a gear bearing from Thingiverse and it came out slanted, but more on one side. Strange effect.

Yes, it is. Also, when the bed is turned off or the bed heater LED is not flickering, the LED panel remains lit without any flicker.

V_FAN jumper is set to VIN. LED wires are connected correctly. I was able to get the panel to work using the Fan 0 output on the Duet WiFi board. I can dim and control it via DWC which is good. The problem now is the panel noticeably flickers at a rate of maybe a couple times a second. Any good way to eliminate this?

Thanks!

I worked the issue and determined it was a break in the fan connector or wiring somewhere that happened at the same time I updated the firmware. Checked further and found a broken ground wire at the board connector for the hot end fan.

Just installed the 1.20beta8+1 and noticed right away that while printing my always on fan for my hot end is no longer always on. As the hot end moves, it revs up and down. The only change made to the printer was to update the firmware.

Not able to get it to go yet. I'm using g-code to control the fan output with M106 P7 S255. The panel didn't do anything so tried other fan outputs on the DueX5 and nothing. I hooked up my scope to the wire ends and checked the output. The scope shows flat line.

Thanks Dave! I'll give it a go and report back.

What's the best way to connect and PWM a 12V LED Panel on the DueX5? I've poked around some on the forum and in the documentation and I'm not sure whether the heater or fan output would be the way to go since it doesn't look like they'll put out 12V once the pin is disabled from either heater or fan control. Perhaps the answer to this and others can be used to start a page in the documentation for Connecting Lighting?

Thanks!

I can only speak from my own learning experience. Duet has a steep and sometimes costly (regarding time) learning curve, especially if what you're doing is currently in development But I will say that David and the forum here are a very dedicated and helpful group of people! Stick with it and once you get your rig up and running, you'll definitely be better for it.

Yes, that was the issue. I upgraded my firmware to 1.20beta4 and tested pause and resume. They work without issues.
Thanks!
