to do that i think you need to declare your second Y axis as U and linked it to the second limit switch.

Then on the Y homing you can move both Y and U until you hit the limits. maybe check on the mpcnc i think i remember they did it a while ago.

If you have RRF3.3 or more you can use variables and it would be easier.

Nope, duet 3 needs reprapfirmware v3 at least.

But honestly it's not that complicated to create your own configuration especially with the configurator from reprap. And after that you can customize the config.g with the help of the one included in this package.

But whatever you do you will have to to setup your motors and limit switches.

I really think it's best to read and understand the config then you will create your own.

Just use small values of current not to burn your steppers (800mah) and test it with motors alone not mounted and use a piece of adhesive tape to see the steppers moving correctly.

And when you connect once mounted do it motor per motor and for the y axis always leave only one motor connected in case you have to reverse it.

There are two different things: the firmware and the web server. The first one is what control the board. The second is configured by the content of the www folder. So you can just put e content of the v1.06 www folder into your sdcard even if with a 1.07 version installed.

Crap I just realize that I wrote craps, I'm using g28 to home. I don't like the g1h1.

I would have write that I use g92 to change the machine coordinate. I use this on some jobs on the z axis after the zprobe when I need a specific offset (I did that only for my job to prepare the martyr).

For my jobs I modified the fusion 360 mpcnc post processor and what I do is set the starting position as the zero on x and y for g55, then switch to g54 and will go to a specific position to perform a zprobe so I can handle tool changes.

And this way if I noted the xy coordinates at start I may redo if I want.

I thought of using Dave coordinates but I have to check how long can it be stocked, with our without power off….

I kinda disagree with you as home is the root of all workspaces g54 up to g59.x

I personally use g92 for homing and g10 to set offsets for my workspaces.

And more important is that it allows me to works in negative coordinates in g55 while keeping the stay in the limits option.

And honestly, I use the firmwares provided by Rian as a helpful first configuration and do my own version. And now if I want to upgrade I do it directly from duet

Great, cool I will get the config files then and update them to suit.

Just a suggestion, keep the name of the firmware with version so people know .

But good job and thanks.

Hi do you have a github where i can check your modification from the original reprap firmware ?

What version do you base your 1.04 version on ?

i’d like to see the modifications as i will use it on the ox i bought you and not a worbee.

also i might need to perform my own modifications to fit some of the specificity of my project.

thanks
