Stupid question I know , have you checked the wiring ?
that all the wires are contacting ?

tracar

@peter247 yes. all good, even replaced with a new harness to test , all good

peter247

Hell if I know what wrong !!
The only thing I can think of is changing the heater pin ,
with M950 S0 C"exp.heater7" and changing the physical pin.
But if it worked before I can see that working too !!!

i just dont get it either. i even reflashed the firmware, it works when i revert the firmware to 2x.
im at a loss on this one i think..

i can always work on the independant z axis for now

peter247

@tracar

yes H7_pwm on the end of the expansion board

Where are you getting H7_pwm from .
i'm using this diagram https://d17kynu4zpq5hy.cloudfront.net/igi/duet3d/vqBUAZPsxMC5tRgt.huge

pin 31 Heater7

here is another clue, after initial power up test bltouch goes in and out a couple o times, then i issue a bltouch test, where its sposta cycle in and out,,, well it does not..... but at that point i can unplug it , plug it back in and it wont do a self test.

@tracar

You have it easy, without the expansion board it is I think the 10th pin from the left on the top set of pins.

It is midnight in the UK , so off to bed now , good luck and hope you find the problem.

@peter247
thanks for all the help. have a goodnight

tracar

i have tried everything i can, except what works. and decided to revert back to 2.05.1
everything works even the bltouch. im going to wait till a more streamlined 3xx comes along.
want to say thanks to everyone for all the help along the way, it was not wasted as it showed me how to get the proper settings for homing and machine travel and set it all right in 2xx.

last question, can the web interface be set up with keyboard commands, such as up , down , left , right arrow keys (keyboard input) to control motion on the printer?

peter247

@tracar

Sounds like something hasn't made the upgrade to 3.1 fully , so when you downgrade it back to version 2 you get it working .

When I upgraded the firmware I first made a copy of my SD and put it on a new SD card so I could go back to the same configurations.

If you keep swapping between the versions with different config files , you may be forgetting to change a setting.

an the web interface be set up with keyboard commands, such as up , down , left , right arrow keys ?

No idea , it need some sort of key mapping .

@tracar Can you post the probe section of your RRF2 config.g? And I know you have confirmed the wiring, but could you post a picture of your Duet with the wiring connected so we can check? When you are moving between RRF2 and RRF3, are you changing all the files (homing and deployprobe etc) or just config.g? Or just using separate SD cards?

@tracar Wiring looks very nice! The only thing I would say is that it would be better to route the endstop and probe wiring further away from the ribbon cable. There have been instances, mainly with the Duex expansion boards, when cables are run over or along the ribbon cable (which is unshielded), it can pick up interference, particularly if you are using Normally Open endstops. The interference is often on the SPI bus, and causes issues with the Duet and Duex communications. I don't know if this issue may effect the driver expansion board too, but it can't hurt moving the wires away from the ribbon cable. I don't know of any change between RRF2 and 3 that may increase the chances of interference; I think it's more likely a configuration issue.

The probe config you posted is still RRF3 (the pins are defined), not the working RRF2 config.

@droftarts
this z probe is what i currently have working in the printer right now . and it fully works with the bl touch.
the signal cables are all shielded, and when i get my 4ch optoisolator the machine will be updated to N/O endstops. and again all shielded cables. but for now they are not physically screwed to the machine for an earth ground till later, after its rebuilt and squared off. the wiring you see is temporary till i get everything installed and working, then everything will be shortend and , as you say some seperation of wires.

@tracar Okay, if this is the code running with RRF2, then please send M98 Pconfig.g and I think you'll see errors. M950 is only supported by RRF3, same with the C parameter in M558. Could you please send M558 and post the response?

What is the probe deploy command (M280) in your working RRF2 deployprobe.g? Is it M280 P7 S10 I1? If it is, for RRF3, try inverting the heater 7 output in M950, ie

M950 S0 C"!exp.heater7" ; create servo pin 0 for BLTouch

Ian

will test 7 hours from now when i get back from work.

@droftarts said in hbot homes correctly but prints mirrored ,:
current:
M280 P7 S10 :deploy bltouch
M280 P7 S90 I1 ;retract pin

also works the same as :
M280 P7 S90 ;retract pin without I1
and with : instead of ; normal?
