So I don't end up putting the code in the S3D software anymore, it is built into the duet? How do I make sure it comes down, the probe touches and prints from that 'mesh/surface'?

That is entirely up to you. Many folks do, I don't. I found I prefer to have all of my print start and print end code in the Duet.

Everything that needs to happen at the start of the print is in the code I place in my print_begin.g file which includes:

homing XYZ
bed leveling
setting bed/hotend temps,
waiting for temps to reach the set points
priming the extruder
pausing to allow user to clean hotend/bed
setting the Z=0 datum
loading the height map

And anything else that I might want to have happen at the start of a print.

There is also a configoveride now that doesn't have all the information that the config.g file does. I guess I need to make sure it uses that first when making a print. Maybe I need a new slicer?

The file config-override.g is processed at boot time when config.g is processed.

There is nothing you need to do with config-override.g at print time.

You can use any slicer you want as I sometimes do.

My approach doesn't care as I simply setup each slicer to call my code at the start and end of a print. My code does not change if I change which slicer I use.

Okay this is the same as Smoothieware on the MKS Base. Thank you!

Thank you my friend. I’m trying to figure all this out, so I appreciate your patience. If there is anything you can share with me as far as code to get me started I’d appreciate it. I know you don’t have a delta so things will be different but I have some things I promised to print (my director) and then my printer burnt out and I’m in a rush.

I have a new surface and hot end and don’t want to be smashing into it. Maybe I put a piece of cardboard over it or something. But anything is greatly appreciated and I appreciate your patience.

Glad to help in anyway I can.

I've listed the primary things that need to get done before a print and thus my print_begin.g file has the commands needed to do those things.

My file also has some code that is just checking to be sure conditions needed for printing are met.

Perhaps if you look back at my print_begin.g file that I posted it will make more sense.

If not ask about any part of it - I can create a simpler version.

I apologize I didn't see where it was, you mean the parts that are listed underneath it or the actual code itself?

My first post to you included my complete print_begin.g and print_end.g files.

In my next to last post I simply listed the basics things that needed to be done before a print.

I thought perhaps my files might make sense now that we have conversed.

I am sorry, yes I see it. I can make it work. I don't know if you want me to post here but can I put my files that I create and have you do a sanity check? I appreciate it.

Now I have to deal with my fans not working now (always on fans).

Thank you again sir.

Does your homing script set the Z=0 datum?

And why are you not waiting for temps to reach their set points?

When it comes z=515. 0 would right at the print surface. I have found on the deltas this is the correct way?

In the config.g it calls out for the temps to reach their set points.

Don't know what you mean.

Config.g? You mean the main config.g?

0 is the print surface, so when I home z=515 and when it prints it’s .xxxx

How can you be waiting for hotends/bed to reach temps when you cannot, as a practical matter, set them in config.g?

It must be done in the slicer? I choose the bed and temp setting, after I slice it in S3D, it has the code in the file (part GCODE file).

No, it does not have to be done in the slicer.

I do it using the filament handling feature in the DWC.

I have entered in a number of different filaments that I use into the DWC.

For each filament entered there is a special config.g file created.

My start code is in a file named print_begin.g and is invoked from the slicer with M98 P"print_begin.g"

In that file I have (among other things) this:

 T0							; select tool 0 so extruder commands below will work
M703							; configure selected filament (sets bed/extruder temps, extrusion multiplier)
; some other unrelated commands
M116							; wait for temps to reach set points

That M703 command invokes the special config.g file for the currently selected filament and in that file I have any commands I want unique to that filament and in that file I set, at a minimum, the bed temp, the hotend temp and the extrusion multiplier.

I have found this to be an effective way to set my temps and I can use different slicers easily as the start code is on the Duet, not in the slicer.

But this is just my way. You should do it in whatever way suits you the best.

Thank you sir, I find I like to 'master' one slicer and I guess I almost put all my eggs in one basket so to speak. I will certainly take advantage of the way you are doing it but I want to get successful at printing the way I am now. I can say my load and unload macros work, ha ha... baby steps

Again thank you for helping!
