Idex Mirror/Duplication mode setup

@gamecrazeddork
It's been a while, when I tried this on my IDEX but AFAIR, I had to set new M208 limits in tpre# for X and U, matching the split print area

gamecrazeddork

@o_lampe ok I think I missed setting up a tpre# file because all I have setup are the tpost and tfree files.

I'll have to look into this, is there an easy guide for setting up this file?

Sorry still new to duet.

Ok I think I got it.

Just made a tpre file and did what you said and it seems to be moving correctly.
I think I will need to mess with the offsets in the slicer to match the vcast now.

Thank you for the help!

Ok I may have been wrong I still don't have it working properly.
I seem to be Mirroring the mirror mode?
Would any one know what would cause this off hand?

This is how the items are sliced with the center being (0,0)

Here is a video of what the machine is doing when it goes to print in mirror mode.

Here are my most up to date files for reference:
config.g tfree3.g tpost3.g tpre3.g

Please help if you can, all input is much appreciated.

@gamecrazeddork you haven't set up the correct X and U tool offsets for the duplication and mirror tools. For example, if the print width is 200mm then you need to offset X by 50mm and U by -50mm in the G10 commands for those tools.

gamecrazeddork

@dc42 Thank you that seems to have done the trick so far, set the offset and its off to the races.

Unfortunately I'm having a strange issue with the Duplication mode now. Where both heads home to the center then the X starts printing while the U is frozen in place.

Do you see anything that stands out that would make it do this? I haven't set the offsets for Duplication mode yet, but I'm guessing this wouldn't make the head not move at all?

I tpre you home X and U before you set the new limits with M208. It should be the other way round or the homing position refers to the old limits.

@o_lampe My mirror mode one is setup the same way and is working the correctly now, is that order really going to make a difference?

I tried switching it around on the duplication mode, but it didn't make any difference.

Still having an issue with U hotend positioning in the center then it doesn't move.

The limits would be the same as mirror mode correct? Just with the direction of the U axis reversed?

@gamecrazeddork said in Idex Mirror/Duplication mode setup:

Config:
M563 P2 D0:1 H1:2 X0:3 F0:2 S"Duplication"

The combination of not setting offsets in M563 and setting axis limits in the tpre file is probably causing the lack of movement.

Thank you @dc42 @o_lampe following both of your advise I was able to get duplication mode working.

Much appreciated!
