Only able to home one axis.

Daz_Rich

HI

Can only home one axis (XY) when asking it to come other it continuously bounces.
Can home x but not Y.
can home Y but not X.

video to add more explanation https://youtu.be/AQs-qj4-ceM

forgot to take info about web ver and firmware updated automatically once connected to raspberry but running latest of everything only set up last week. (none beta)
will add any info soon. (machines at grandads)
Nice to go over with a fresh idea.

I have edited config and homexy roteans but both looks fine to me

duet3 mb 6h and a raspberry pi 3b+

I put in G1 H2 X-5 F6000; thinking it was somthing like having the microswitch on before it moved.

I'm waiting for another z endstop so not tested Z yet,

Cheers Darrell

more ramblings
I just dont get how it can be in the setup code if it will work on the axis as long as it was done first.

You have driver 0.0 bound to both Z and U in your config.

M584 X0.2 Y0.1 Z0.3:0.0 U0.0 E0.5                           ; set drive mapping
M350 X64 Y64 Z16 U16 E16 I1

This may be causing some issues as well. Do you have a homeu.g as well?

It seems you want to home the Z motors as independent axis. This is no longer required in RRF3. You can assign two endstops to the Z axis M574 command and home Z as a single axis and it will move each motor until their respective endstops are triggered.

If you did not want to do that you could still split the axis into Z and U, but you would only need to do that before homing.

See examples here: https://docs.duet3d.com/en/User_manual/Connecting_hardware/Z_probe_auto_levelling

In your home X and Y files only use H2 when you want to move an axis before it has been homed or may need to move when it may not be homed. Once you've done a homing move for that axis it should be homed, so don't use H2 at that point. Using H2 may hide a homing problem.

I can't really tell from your video what exactly is happening.

Please test your endstops with M119 and confirm they are assigned correctly and showing the expected state.

@phaedrux
home U is the second Z axis, compied and adapted that from
https://duet3d.dozuki.com/Guide/Independent+Z+motors+and+endstop+switches+in+RRF2/18

but shouldn't be in use yet with this problem,

@phaedrux
Seen cheers, will give it a go tomorrow
Much appreciated.

I'm an idiot Will go update and report back
duet fail.jpg

might have just found it. but im confused give me a mo
DSF VERSION 3.30

ReRap firmware for duet 3 mb6hc versiom 3.01-rc9 running on duet 3 b1.01 or later

same error occures if I home X then Home X again, Just keeps hitting endstop and restarting homing cycle for selected axis
So X Y Z can all home but only if board is restarted inbetween. If I try to Home X then X fail.--- X then Y fail ect
Seems to just restart the homing file after first home.

Tried changing homing x - y file to as basic as possible
Tried adding a G92 on end
Tried a a fully blind config, direct from configerator and still fails to home, but was still showing 4 heaters on graph so can't have been a full reset of instuction
Ran M119 every axis workign accordingly

implimented the Z changes and Z homes sucessfully, but won't home a second time.

Could it be somthing in the web interface raspberry pi part?

Were you able to get the firmware updated?

sudo apt update and sudo apt upgrade on the pi should get it, but if it's still showing 3.01rc9 after that it may need to get manually updated to get back in sync. In which case you can try uploading the bin file for the 6HC in the web interface to the system tab and seeing if it will update. Otherwise you'll have to use bossa to flash it via USB.

https://github.com/Duet3D/RepRapFirmware/releases/download/3.3/Duet3Firmware_MB6HC.bin

When you send M119 was it showing the endstops triggered or not triggered as they should have been?

Can you confirm axis movement directions are correct?

When looking at the machine from the front, 0,0 should be in the front left corner, -x move to the left, +x move to the right, -y move to the front, +y move to the back, -z moves the bed and nozzle apart, +z moves the bed and nozzle together.

Based on that, where are the endstops physically located? Left/right front/back?

@phaedrux said in Only able to home one axis.:

wing the endstops triggered or not triggered as they should have been?
Can you confirm axis movement directions are correct?

Managed to update it with Bocca with computer someone left erase jumper in and tried to program it, Verification was intersting .

All axis moving as should be.

m119 showed all not stopped.
then pushed each one and ran m119 to check

X end stop right hand side so when homed = 1000
Y end stop back of machine when pushed = 220
Z end stops top of machine either end of bed when pushed = 0
not sure what "moves the bed and nozzle together." you mean

Z homing works as should as well, with updated G code from your instruction

Cheers for your help,
Be nice to get it finished now, hopefully get a finished build picture of what might be the longest creality ender 5 pro.

I've got to nip out so will be slow responding

Phaedrux

So it's all homing and moving correctly now?

Daz_Rich

@phaedrux yes, how do I mark as solved?
