Railcore Build Homing In The Incorrect Direction
@fcwilt could you give an example of what the looks like ?
- the x any y files are seperate*
do you mean this
M574 X1 S0
M574 Y1 S0
M574 Z0 S0
@tycarr that is not needed for RRF2 so ignore the need to split them out.
your homing file for Y instructs it to go towards the minima of the axis, which is where you indicate the Y endstop is. This indicates its actually one of your motors turning the wrong way.
Can you repost your original image but mark up which direct is + and - for X and Y and where the endstops are?
im still pretty new to this and the directions are kind of confusing to know what movement is actually - and + ,
this is the railcore starting moves link , when i run these moves the machine moves into the correct positions
G1 H2 X10 F3000
G1 H2 Y10 F3000
OK, based on the way you're currently set up, I have marked up the image above, to show which way everything is going.
I think the first step is to determine what you want to call the front of the machine. typically, the X axis goes left to right and the y axis goes forwards and backwards. You also need to determine which axis is X and which is Y.
Does that make sense?
@jay_s_uk yeah i get that part
@tycarr so your M671 locations are in the wrong place.
So when jogging your motors, do they move in the directions as indicated in my image above?
@tycarr What board are you running on your RailCore? And what firmware?
There is a baseline for the RailCore on the railcore webpage. I can give you my config, but you need to running RRF3.3.0 I am also running a Duet3 Mini 5+ and a 1LC toolboard
@jay_s_uk This printer is confusing, took me a while to get my head round it!
Where the markup in the picture is +Y and -Y in yellow, that is actually the X axis
So X0Y0 is bottom left of the picture. Y280 is at the top of the picture.
It is all relevant to the hole in the front panel.
@Tycarr If you need some help with the RailCore, let me know.
Just incase you did not know, there is a RailCore group on Discord.
If you have a discord username, let me have it and I will invite you, unless you have already found it!
@jay_s_uk You have to ignore where the hotend fan is pointing, as it points left, looking at the front of the printer.
@paulhew I'm not sure what the fan has to do with it
Thats the front of the printer.
A majority of printers you would see the hotend fan facing you, like the Ender3, Vorons etc.
Thats how I and some people get lost.
