Rat0S for V-Core 3 hybrid
I have RatOS working on my V Core 3 hybrid 300
Z tilt and Bed Mesh are working perfectly. (Probing and meshing the correct points) on the bed)
If I place an item in the middle of the bed in slicer, it prints it in the middle of the bed without any offset.
However
1. Z homing has an offset to the left of the centre of the bed and
2. The prime blob is offset to the left as well.
I am not sure what I need to do and where I need to do it to correct these two minor issues?
To get hybrid mode working so far I just used the configurator set up wizard for the V-Core 4 hybrind and then added the following over writes in printer.cfg
[stepper_x]
position_max: 300
position_endstop: 0
position_min: 0
[stepper_y]
position_max: 300
position_min: 0
position_endstop: 0

when you home X and Y, and then tell it to go to x=0,y=0 does that line up with the front left corner of your bed? It might be off because of that and you needing to adjust the endstops in the config
Besides calibrating your position_endstop/min/max, if you're using the V-Core 4 on a different printer, you need to adjust the
bed_margin variables (find them in ratos.cfg) to match the amount of travel outside the print volume on your specific printer.
The homing doesn't take probe offset into account, that's on purpose.Yep G1 X0 Y0 works perfectly.
Many thanks!
I have added the following overrides in printer.cfg and it has resolved that issue.
[gcode_macro RatOS]
variable_bed_margin_x: [0, 0]
variable_bed_margin_y: [0, 0]
Loving the V-Core 3 hybrid and RatOS made setting it up so easy, only left me a couple of minor steps as per this thread that I needed to do.
I left the Y stop in the current V-Core 3 location hence the only other changes I needed to do.
[stepper_x]
position_max: 300
position_endstop: 0
position_min: 0
[stepper_y]

Dear Santa Miklschmidt is there any chance of a configuraton for V-Core 3 Hybrid in RatOS configuration Wizard at some point in the future?
FYI (and amusement)
These are the overrides I have in printer.cfg
Note I use the Microlight print head with Beacon which has a different Y off set and I use a CPAP fan hence the fan settings. I use and adxl 345 board mounted on the top plate of my print head rather than the Beacon's Accelerometer.
I use two separate fan ports on the Octopus for the two fans that cool my stepper drivers.
Otherwise everything else is standard V Core 4 for the purposes of RatOS set up.

Dear Santa Miklschmidt is there any chance of a configuraton for V-Core 3 Hybrid in RatOS configuration Wizard at some point in the future?Absolutely! 🙂
Let me know if I can assist in anyway.
I mean, if you're up for it, you could submit a PR where you've just duplicated the V-Core 4 hybrid config and made the changes to limits, margins and mesh/z_tilt positions, then we can take it from there?
It's basically just about click "Fork" on https://github.com/Rat-OS/RatOS-configurator then make the changes, commit and click the pull request button 🙂

Sorry I haven't used Github before (except to download the occassional CAD file). I think if I attempt this I will make a mess of it. Is it possible for you to extract what you need from the printer.cfg file I posted above?
Some of my values might be slightly different because my Beacon offsetr to the nozzle is slightly different as I use the Microlight Print head instead of a Rat Rig one.
I can assist by testing anything you want tested. My config seems to be working OK.
hope this happens and get vcore v3.1 hybrid in the configurator coming to the firmware very soon up for test as well if needed?
Thank you MFBS for the work you have put in and miklschmidt for all the work you do much appreciated.
