Duet 2 WiFi Ender 3 v2 Help Please

[andnosobabin]

I rebuilt my ender 3 v2 with a new ender 2, got everything wired up correctly (i hope/ think). I ran the configurator and used the ender 3 pro config settings for a base then modified for the microswiss DDM im using etc but cant get to the printer to set the origin to 0,0 also im not sure about how to get the heaters calibrated either. If someone would help walk me through this or at least point me in the right direction i would be forever grateful!!

Thanks
Brad

p.s. sorry if im missing needed details etc... im falling asleep as i type this lol and been fighting the printer all week.

for pid tuning see

get to the printer to set the origin to 0,0

this is done modifying the M208 command. then you go to x0 y0 were is the nozzle?

[andnosobabin]

@Veti thanks for your reply!!
x0 y0 goes to the front left corner when facing the printer

[Veti]

directly above or an offset?

if so measure the modify the M208 minimum according to the offset in your config.g

[andnosobabin]

@Veti offset.
i changed the config.g to show:

; Axis Limits
M208 X8 Y5 Z0 S1 ; set axis minima
M208 X235 Y235 Z220 S0 ; set axis maxima

but when i send "g1 x0 y0" its still goes off the build plate.

i think you added instead of subtracting

try
M208 X-5 Y-10 Z0 S1

@Veti Awesome that worked!!

Last thing (i hope lol)

I ran the M303 H0 and H1 commands to PID tune my hot end and bed. The hotend seemed to tune correctly and i put the results in my config.g file no issues (so far) but the bed heater either takes hours to tune, gives me an error saying it cant be tuned, or the one time i got a result I entered it and still got the heater is heating up too slowly error.

[Phaedrux]

What exactly does it say when trying to tune the bed? It can take a while to tune.

[andnosobabin]

@Phaedrux Well it seems to have worked this time. I might have used the wrong settings when i used the config tool. It does say this:

Warning: heater behaviour was not consistent during tuning
Auto tuning heater 0 completed after 3 idle and 25 tuning cycles in 2864 seconds. This heater needs the following M307 command:
M307 H0 R0.322 C440.5 D3.78 S1.00 V24.1
Send M500 to save this command in config-override.g

No errors when heating the bed so can I assume that things are all fine then?
