Can't seem to set where the bed should be when print starts
-
@Phaedrux Thanks for all of your help and for sticking with me.
I will do the auto bed levelling next. I did look at the height map that I had and it looks terrible. I am currently printing a case for the duet 2 board to make it a little safer and hopefully protect the actual wiring. I know I should have done the auto bed levelling first. |I had some quality issues and some print lifting. I should have really cleaned the print surface first. Just because it's brand new doesn't mean it is ready to go. I will also need to go over the extruder setup as I can see from the print that it is no set properly.
I did add a dual gear extruder, but I am thinking that maybe I should stack it on the carriage and get rid of the long bowden tube. Any thoughts or cautions I should know about?

Just follow the principle of one thing at a time.

Always good solid advice. Most of my issues with why I wrote in for help are related to no knowing which problem was creating which challenge. -
@TimV-0 Hi: I sent out the G29 last night to generate a heightmap.
It sampled lots of spots on the bed and I got no feedback.I tried printing today and I have a small forest of PLA that I wasn't expecting.
I clicked on the heightmap and it is empty. I'm sure the bed is not perfectly flat.
Is there somewhere I should have saved it when it finished? I think I sent an M500 because I thought I should.

It kind of sounds like you might have your DWC version out of date.
Upload this zip file to the system tab in DWC. That should get everything up to date.
https://github.com/Duet3D/RepRapFirmware/releases/download/3.4.4/Duet2and3Firmware-3.4.4.zip
Also check that the heightmap plugin is enabled and maybe clear your browser cache.

Thanks for the file. I can't be certain for all of the files, but the .zip file is the one that I have loaded.The heightmap tab was a big orange icon that said stop in the plugins. All the other plugins said start. Is this backwards or was it the only plug in running and I just shut it off? I clicked it again and it still shows the big green icon that says start?
I have lost the heightmap icon on the main DWC which is what I clicked to see it in the first place. Not there any more.
I'll just pretend I know what I am doing for now as I don't really want to restart the print
The screens don\t seem to display what I would expect...

All my plug ins say they are 3.4.4 -

If the plugin says stop, that means it's running. Clicking stop, stopped it. So no heightmap.
Start it again. This time go to the system tab in DWC and find the heightmap.csv file and delete it and then send G29 S0 to create a new mesh.

I am very happy with the print quality that I am getting. I'm trying to deal with a couple of small things that remain.It happens from time to time between prints that I will get a message that I do not have an extruder selected or online or whatever. I can click on the tool and it will resolve. I would appreciate knowing how to make sure that it is always on when I either turn on the printer or send a job.
It would also be nice if it would automatically heat the nozzle to the temperature that I want up front. I suspect that I am missing a key line somewhere. Should I put it in config.g, or in the start code from the slicer?
Along the same lines, when the print finishes, I would like to shut off both the nozzle heater and the bed heater.

You should add
T0to the end of your config.g so that a tool is selected at startup, and you should do the same in either your slicer start gcode, or create a macro file called start.g in the system folder, and have any commands there that you want to happen before the print starts. Such as select a tool, preheat the bed or extruder, move to a certain position, home the printer, whatever you want.@TimV-0 said in Can't seem to set where the bed should be when print starts:

That would usually be done in the slicer. What exactly do you want to happen? What happens now?

I find the easiest way to do this is to create another macro file in the system folder called stop.g and in it place any commands you want to happen after a print is finished. Then in the slicer end gcode, add
M0which will call your stop.g macro. -

Sorry for the delay. It turns out that I made some slicer changes to try to center the print on the bed, and then homed the printer, and wire tied the extruder tube...The point is that I "fixed" multiple things at the same time, and my X limit switch became loose and that caused a huge set of issues until I figured out that it was not actually working / connected.
This is an ender 5 pro that I converted to the Duet 2 Wifi board. I kept the ender5 limit switches but replaced the wiring with generic 3 pin wires to the board. I am having problems keeping the wires connected at the end stops. I applied heat shrink tubing at the limit switch end, so they now all look perfect but seem to vibrate loose.
Would you be willing to offer an opinion on a more reliable end stop setup that I could connect directly to the duet 2 endstop to stop having endstop switch connection issues?

With proper connectors, this should not happen. Maybe the wires are too "generic"?

. Use proper connectors or a good soldering iron - the switches are just fine.
