Your motor currents are much lower in our RRF3 config.

M574 S0 is not supported in RRF3 anymore.

https://duet3d.dozuki.com/Wiki/Gcode#Section_M574_RepRapFirmware_Num_3

Endstop type S0 (active low switch) is no longer supported in M574 commands. Instead, use type S1 and invert the input by prefixing the pin name with '!'. Ex: M574 X1 S1 P"!xstop". Invert the input when using an NPN output inductive or capacitive sensor, or using a NO switch (not recommended, use a NC switch instead).

So that may explain your Y endstop issue.

Use M574 Y1 S1 P"!ystop" instead.

For the BLTouch you have M558 P9 C"zprobe.in+zprobe.mod" H5 F120 T6000 remove the +zprobe.mod part. The modulation shouldn't be used. In the configurator it is selected by default and should be deselected. It's on the change list to have that fixed as it tends to catch people out quite often. Sorry about that.

Also for the BLTouch, what do you have for your deploy and retract macros? Does M401 and M402 work to deploy and retract the pin?

@Foden said in Upgrading from RRF2 to RRF3 issues:

M558 P9 C"zprobe.in+zprobe.mod" H5 F120 T6000 ; set Z probe type to bltouch and the dive height + speeds

Recent versions of BLTouch need the pullup resistor enabled too:

M558 P9 C"^zprobe.in" H5 F120 T6000 ; set Z probe type to bltouch and the dive height + speeds

@Phaedrux Thanks Phaedrux

Motor currents - looks like i messed up there as it is taking the values now

Missed the M574 info - thought i had read it all properly, obviously not and appreciate the heads up. However that code was all created by the configuration tool

BLTouch - yes M401 & M402 work as expected

@dc42 Thanks DC42

Working through Phaedrux and your updates

Much appreciated guys!!!

Foden

@Foden Quick and outstanding support as ever - THANK YOU guys

Homing of the Y axis now works as expected as does the BLTouch. So was I selecting the wrong thing(s) here are there changes coming for the config tool? I was trying to keep my initial, baseline, config clean and created by the config tool before I dirty it with tweaking and fiddling with it

Phaedrux

The config tool is yet to be updated fully and is still outputting S0 rather than ! on the pin. It's on the list for the next update.

Glad it's working though,

@Phaedrux

Just noticed that if i do X home more than once (paranoia kicking in) X axis keeps moving to the right. Checked the endstop status and X is showing as triggered regardless of whether it actually is or not. Haven't messed with any cables and the optical sensor itself was working properly

; Endstops
M574 X1 S1 P"xstop" ; configure active-high endstop for low end on X via pin xstop
M574 Y1 S1 P"!ystop" ; configure active-low endstop for low end on Y via pin ystop
M574 Z1 S2 ; configure Z-probe endstop for low end on Z

; Z-Probe
M950 S0 C"exp.heater7" ; create servo pin 0 for BLTouch
M558 P9 C"^zprobe.in" H5 F120 T6000 ; set Z probe type to bltouch and the dive height + speeds
G31 P500 X-26.5 Y-12 Z2.14 ; set Z probe trigger value, offset and trigger height
M557 X20:275 Y20:275 S20 ; define mesh grid

Stepped away from it for awhile, hit the emergency stop so it knows I'm still in charge and now it works like it should

No sane person would build their own 3D printer I guess

Thanks again!

Phaedrux

Given that this is a CoreXY we should verify that your motor directions are correct and that you are configured to use a right hand coordinate system.

I'll point you to this post which goes through the steps of verifying that everything is set correctly (end stop positions, homing directions, and motor rotations)

@Phaedrux

I looked through the link

Motor directions are correct and haven't changed since original setup some years ago. Y endstop was changed when an optical sensor died and I only had mechanical spares so it was swapped and I haven't swapped it back since

As I mentioned, once I left it alone and the hit the emergency button all is well - go figure

Is this with RRF 3.0 or with RRF 3.01-RC11 ? I recommend you use 3.01-RC11.

It was with 3.01-RC11 - once I left it alone and the hit the emergency button all was well
