Pay for config / json files for my corexy printer build.

I have followed Mark Rehorst's (thank you Mark) how to set up core xy origin and Endstops article origin is at Alpha motor all positive movement is in the direction of the top right pulley.
The tool homes back to the Alpha motor.
-
@stevo Do you have a problem with the motion or not? - I'm a bit confused because it sounds like it's doing what it should do..
To be clear, if you command an X positive move, the print head moves from left to right in your diagram and there is no movement in the Y direction. Yes or no? If no, what happens when you command an X only positive move?
Conversely, if you command an X negative move, the head moves from right to left and there is no movement in the Y direction yes or no?
And a Y positive move moves the head towards the back and there is no movement left or right. Yes?

@deckingman Yes it ticks all the boxes Veti mentioned in still appeared to be in cartesian mode guess its my poor description lol
Thank you
-
please post your config.g so we can have a look at what you configured so far.

This is where I'm up to so far.
Im in the process of adding the BLtouch wiring to the existing loom need to remove existing Z axis end stop.; Configuration file for Duet WiFi (firmware version 1.21)

@veti Yes i am

M669
whats is the output if you issue M669 in the console.
-
@stevo One thing about your config.g that looks odd to me is that the steps per mm for Z look right for a metric lead screw but looking at your machine name, I'd have thought that you would be using Acme threads
-
1600 is a lead screw 1 start 2mm lead.
some people use them because it allows for 0.01mm layer height variation. -

-
Should probably switch joke supplier;)

Yes, a joke never works when you have to explain it...........

that went straight over my head.

This be the "Road runner" lol
Finished it last year enjoyed nearly every minute of the build lol

@veti as follows.....

Evening,
If I wanted to home y axis first prior to the x due to how i plan to locate the x and y endstops have I made suitable alterations to the home all file to do this ?
Be gentle lol; homeall.g

G91 ; relative positioning
G1 Z15 F6000 S2 ; lift Z relative to current position
G1 S1 Y445 F1800 ; move quickly to Y endstop and stop there (first pass)
G1 S1 X445 F1800 ; move quickly to X endstop and stop there (first pass)
G1 X-5 Y-5 F6000 ; go back a few mm
G1 S1 X445 F360 ; move slowly to X axis endstop once more (second pass)
G1 S1 Y445 ; then move slowly to Y axis endstop
G90 ; absolute positioning
G1 X188 Y-222 F6000 ; go to first bed probe point and home Z
G30 ; home Z by probing the bed -
Yes that looks correct.
-
@phaedrux should I swap around the x and “move slowly” commands ? Towards the end of the file
-
That will depend if the end stops will still be lined up or not. If you need to get Y homed first to line up X, is the switch contact area large enough to trigger 5mm away? If it's still going to miss, you can switch the order of the second X and Y moves so that it moves Y first.
You can copy and paste each line of the macro into the gcode console to execute it one at a time for testing to make sure it actually works.
