@phaedrux oh that's funny. I'm going to try that.

Duet Wifi
RRF 3.2.2
AC silicone heater w/SSR, Thermistor

The heated bed was working on RRF2.1. Since upgrading it has not worked.
When I turned on my heated bed I received "Error: Heater 0 fault: temperature rising much more slowly than the expected 1.1°C/sec"
Spurious heater faults and how to avoid them recommended running a PID tune.

I tried to run M303 T0 S60 and that turned on my extruder
M303 T1 S60 gave me an error saying "Error: M303: tool 1 not found"

If I understand the gcode correctly, T0 should be the bed heater and T1 should be the extruder.

I should also add that my heater settings in RRF 2.1 was
M305 P0 T100000 B4138 C0 R4700 ; Set thermistor + ADC parameters for heater 0
M143 H0 S120

Why isn't my bed heating up? what am I doing wrong?

@phaedrux I was also trying to get my E3D PT100 sensor to work and your code helped. Could you explain why this works? Why does it need p"spi.cs1"? why is it configuring the sensor 1 as a thermocouple?

@phaedrux
Changing the X2 Y2 to X1 Y1 seems to have done the trick.

I setup the grid from fcwilt's advice.

Thanks everybody. I really appreciate it. For some reason going to RRF 2.1 to RRF 3.2.2 really confused me so thank you all for helping me get back up and running.

Hmm, my endstops are physically located in the front left corner. That is my 0,0 point.
-X moves left, +X moves right
-Y moves to the front, +Y moves to the back

My homing sequence is working for x,y and z.

Are endstops supposed to be active low? should I invert it like is shows in the M574 Gcode dictonary?

"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)."

@phaedrux the extruder carriage moves towards the origin and physically crashes. It ignores the end stops. I was really close to the origin and wasn't expecting that to happen when I first ran the mesh bed compensation macro, which is G29, and it actually split my 9mm wide gt2 timing belt when it crashed. It was absolutely terrifying and awesome to see the belt split like that.

I can now home all of the axis. Thank you guys for helping with that. The next problem is, when I run Mesh bed compensation it will move to the origin and crash.

My Mesh Grid macro is simply G29 S0

I got closer with homez. Thanks Nuramori your code helped a lot.

the code below works but moves the nozzle an extra 15mm in x and y.

Question, I commented out the relative positioning and only had it as absolute positioning. I already ran homex and homey then why is it moving towards x0,y0 and crash?

Its wired exactly like the Duet 2 WiFi/Ethernet without expansion board picture from https://duet3d.dozuki.com/Wiki/Connecting_a_Z_probe#Section_BLTouch

M401 and M402 do not work.

That makes sense to move G29 S1 to the end of the config.g file. Done.

thank you everyone for the replies because I've been stuck.
Corexy
duet 2 wifi 2 board. a very early version, one of the early bird boards.
hooked up my bltouch according to without expansion board https://duet3d.dozuki.com/Wiki/Connecting_a_Z_probe#Section_BLTouch

It was working great on RRF 2.1 but stopped working when I upgraded to 3.2.2

What works:
web control
Home X and Home Y works
bltouch lights up and deploys/retracts during startup
sending deployprobe.g ( M280 P0 S10 ) and retractprobe.g ( M280 P0 S90 )

what doesn't work:
z home
height map
deploy/retract macros
I haven't done anything with the heater, fans or tools sections yet.

I have a custom corexy that was running great on rrf 2.1 (duet wifi board) until I bought a new router. It wouldn't connect to the Wifi. I did some research and found how to update the SSID and password. Then I had the stupid idea of why don't I upgrade the firmware while I'm at it. That's where the problems started. I have most of my config file working but I can't figure out the Bltouch for the life of me. Does anyone have a good config.g file of a corexy with a bltouch I can see as an example?
