@fcwilt Thank you very much!

@fcwilt I will fully admit I can't follow it. My script for my TLM pre-duet was a few lines. I am lost on how to get it so it doesn't a single probe to get the right height and get up axis.

I'm sorry but I don't understand the question.

If you are asking about setting the Z=0 datum that happens in the "mesh_comp_map_load.g".

One of the things that you always do before loading the height map is setting the Z=0 datum.

I have it in that file to be sure the height map is loaded correctly.

Here is a simplified version of that file:

M98 P"probe_set_z.g"; set Z=0 Datum

G29 S1              ; load existing height map

M376 H0             ; set bed compensation taper (0 = no taper)

M98 P"probe_set_z.g"; set Z=0 Datum G29 S1 ; load existing height map M376 H0 ; set bed compensation taper (0 = no taper)

I must be really ignorant... I don' have a "mesh_comp_map_load.g"

Where you see M98 P"...." that M98 command is executing a file that I created to perform a specific task.

Whenever I have a hunk of code I need to execute from more than one location I place that code in a separate file that I can invoke as needed with M98. That way I don't have any duplicate code appearing in multiple locations.

The common files you are likely to see are:

config.g
homeall.g
homex.g
homey.g
homez.g
bed.g
mesh.g

In addition to these I have 27 other files of my own creation that perform specific tasks.

@fcwilt Okay, thank you for the explanation my friend.

Glad to help.

Do not hesitate to ask any questions you may have - that's how we all learn.

@fcwilt I have no clue or have a start of where I need to go, but am not close to you....

Well let's back up a bit.

What is it you want to do but don't know how to do?

I and others here can provide simple step by step code/instructions to do anything that needs to happen at the start of a print or the end of a print.

@fcwilt Right now I don't have any code (except old Little Monster Smoothieware code) and I went to print something and the z-probe didn't extend and the height went to low, I did the offset and have done the work to get it all set up, but don't know how to start it and how to end the code. This is all new to me, and it was unexpected. The MKS Base card burnt out so I went with the Duet and have not had the time to do my research like I always like to do. I just don't want to break something in the process.

fcwilt

@noblebran

Have you created the basic files I mentioned and have you installed them on the Duet?

config.g
homeall.g
homex.g
homey.g
homez.g

@fcwilt Sorry I was in bed and working now. I have done all (not to say they are right or not).

OK lets check those files.

using the </> tag post copy&paste the contents of each file in a separate tag.

The </> tag creates a scrollable region and makes viewing code easy.

Great.

Now I don't have any delta printers so I had to check.

For a delta printer the RRF configuration tool doesn't create those four homing files, just homedelta.g

The homeall.g you posted looks like what the homedelta.g file should be.

So get rid of homex.g homey.g and homez.g and then rename homeall.g to homedelta.g.

Now with that out of the way let's turn to config.g.

You have an M587 there which not be used in config.g. You use that command when setting up the WiFi connection but you don't keep it in config.g.

At first glance everything else looks reasonable.

Does the PanelDue work?

Does homing work?

Can you move the nozzle to all places in the printable area?

Can you move over the range of the Z axis?

If you move to Z=10 and do a G30 does the Z probe work?

If you activate the heaters do they heat as expected to whatever temperature you specified?

Do the fans work?

Thanks.
