X-Axis Endstop min and max
is it possible to define an extra endstop for x-axis max position?
I have a dual extruder parking system and I want to use a maximum endstop wich is the exact parking position for the second extruder.
I have a printing area of 290mm and the parking position for the second extruder is 310mm so if I make a toolchange I want to go to positive direction with the x axis until the max endstop hits.
Thanks for your help,
It sounds to me that you have an IDEX (independent dual X carriage) machine. Have you read https://duet3d.dozuki.com/Wiki/ConfiguringMultipleIndependentXcarriagesCartesian ?
Hello thank you for your help,
I have 1 carriage wich is piking up the extruders from their parking position, something like this.

So should I set it up as an IDEX machine?
It's probably simpler not to set it up as an IDEX. Until we support remapping endstop inputs (which is planned soon), I think the easiest option will be to set up your X max endstop switch as if it is an alternate Z probe. Then you can use the M574 command to select endstop type = Z probe when you want to home to max X.
Alternatively, can you use stall detection for the max endstop?

Ok, I have read the document about the IDEX configuration.
I think the setup would work fine for me, but how does it work while printing or to slice the G-code then I have to tell the printer if tool0 is connected it has to move the x-axis and if tool1 is connected then it has to move the u-axis. How does this work? Or does the firmware do this automatically?
The firmware does the mapping from X to U automatically if you set up X axis mapping in your M563 tool definition command. However, I don't think you need to use a U axis. See my previous reply.
Ok thank you.
I will test both methods because sometimes my offset for the x-axis is not correct anymore, and I don't know why. I set it up, then I print something and maybe some prints later the offset is faulty.
Maybe the adjustment with a second x-axis would be easier or work better. I will test it.
When does the firmware exactly switch from x to u axis? Right at the moment, the second tool is readily connected?
Thank you very much for your help.
