Y Axis doing strange things while homing

here is my homeg

[[language]] G28 Y Error: G0/G1: insufficient axes homedSo I remove it and it starts but instead of just moving away 5mm once homed it goes over to position +235 (the other end of the y Axis)
i have tried all sorts of numbers but it just goes all the way to the other side

Seems like you're running the latest firmware. The release notes state that you now have to add S2 to the G1 Z commands.

ok, I got it to where I want it to be. THANKS.
Now another problem once it is homed.
if a click the head movement to move it 1mm it goes all the way the full length of the bed no matter what amount i click
0.1mm
1mm or 100mmMy New Home All.g is
[[language]] G91 ; relative mode G1 Z4 F200 S2 ; raise head 4mm G1 X-270 Y-270 F3000 S1 ; move up to 240mm in the -X and -Y directions until the homing switches are triggered G1 X5 Y5 F600 S2; move slowly 6mm in +X and +Y directions G1 X-10 Y-10 S1 ; move up to 10mm in the -X and -Y directions until the homing switches are triggered G1 X5 Y5 F600 S2; move slowly 6mm in +X and +Y directions G90 ; back to absolute mode G1 X70 Y70 F2000 S2; put head over the centre of the bed, or wherever you want to probe G30 ; lower head, stop when probe triggered and set Z to trigger height G1 Y30 X30 S2 -
Add G91 to the end of your homeall.g file. What's happening is that you have a G90 just before the G1 X70 Y70 …. move, which puts the machine into absolute coordinates so that it moves to the position 70mm away from home in X and Y which is fine. But when you've finished the homing it is still in absolute mode. So when you next do G1 X1, you are asking it to move to the position 1mm away from home, not 1mm away from where it was. Adding G91 to the end of your homeall file will put it back into relative positioning so then when you do G1 X1, will move by 1mm not to 1mm away from home.
-
Adding G91 at the end of homeall.g won't help, because the original relative/absolute behaviour will be restored when the macro file terminates.
I suspect a problem with your M92 and/or M350 commands in config.g. So please post your config.g file, and tell us what sort of motion system you are using.

When you say it goes the full length of the bed when you ask for 0.1mm movement, is that in the X or the Y direction?
Your X steps/mm in the M92 command is very high (1600). Are you sure it is correct? 80 or 160 would be more usual.
Are you using the web interface to command movement, or a USB host program, if so which program?

Y Moves all the way from the endstop
im using the web interface yes.
and i have leadscrews with a 2mm pitch i have tested the mm settings and yes 10mm moved 10mm on all axis when i first was setting it up that was the first thing i did -
its an old 200X275 printer i used to have repiter and a generic controller on it .
but i upgraded with a duet ethernet and i already have a 400X400 working fine but as i learnt i have put the new firmware on this and it seems a lot harder to config as the old firmwarethe 200X275 is
Firmware Name: RepRapFirmware for Duet 2 WiFi/Ethernet
Firmware Electronics: Duet Ethernet 1.02 or later
Firmware Version: 1.21 (2018-03-21)
Web Interface Version: 1.21The Endstop on the X-axis in on the left
The End Stop on the Y axis in at the rear
as you look at the front of the machinei am using an inferred Z Probe the seems to work fine
but the big 400X400 that works fine

This is what's wrong:
M208 X-5 Y275 Z-3 S1 ; Set axis minima
M208 X200 Y-200 Z200 S0 ; Set axis maximaYou have the Y275 and Y-200 the wrong way round.
-
well it didn't help, in fact, made things worse.
now it goes over to the end stop on the y Axis even when clicking + or - 1mm on any axis then stops then once it reaches the end stop I can move the X but not the Y -
In that case you either have your M574 commands set up incorrectly, or your homing files set up incorrectly. Please specify the following locations, looking at the front of the machine:
1. Where you expect X=0 Y=0 to be;
2. Where your X endstop switch is;
3. Where your Y endstop switch is. -
got it

so im moving manual with code to X0 Y0 And then setting the position manually
not sure if i need
G90 ; back to absolute modeat the bottom
