@gorf26 I just stumbled across this thread and have taken a quick look at your config.g file. A couple of things leapt out at me.
You've set micro-stepping for 32X in your M350 but then on the next line you've put the steps per mm in at values which look very much like 16X. So you either need to set micro-stepping to 16X (and I recommend you do that plus use I1 to turn on interpolation), or you need to double or the steps per mm. For future reference, if you reverse the order of those commands (i.e, put the M92 steps per mm before the M350 micro-step[ping) then you just set the micro-stepping for 16X and if you then change the M350 micro-stepping setting, the firmware will automatically re-calculate the steps per mm.
You've set the axis limits for X and Y using "M208 X-5:325 Y0:325 ;" which is fine but then just under that you've set them again using M208 X0 Y0 Z0 S1 ; Set axis minima and M208 X330 Y330 Z330 S0 ; Set axis maxima. These values will override the previous ones.
Also you commented in the file that "X carriage moves from -5 to 205, Y bed goes from 0 to 200". Either the comment is wrong or the values are wrong. If that comment is true, then you need to set the axes minima and maxima to those values and not 0 to 330 for all 3 axes. Also the mesh grid would need to be changed if you do change the axes maxima.
Fan 0 (M106 P0) is usual the part cooling fan - the one that is controlled by slicer generated M106 commands. But you have it set to come on thermostatically when the hot end heater reaches 45 deg C (the same as your hot end heat sink fan). If you want fan 0 to be the part cooling fan, then use something like M106 P0 S0 I0 F500 H-1.
I can't comment on your probe settings as I don't use a piezo. The rest of you settings look reasonable although I would set extruder jerk very much higher but as it is, the worse that can happen is that it might slow down your prints a bit if you try and ramp the speed up.

Thanks made some changes not sure if the not sure if the m280 is set right
Also do I need to add any motors to the m350 m92 one for the E1 motor? do I use U ?
or am I good as is?; Configuration file for Duet WiFi (firmware version 1.21)

............I guess you meant M208 and not M280 but yes, if the new comment about axis movement s correct, then the minima and maxima are correct.
M350 and M92 are on a per axis and per extruder basis so no, you don't need to add anything to what you have. It can get a little confusing if you have multiple extruders mapped to multiple drives but you don't have to worry about that. Your single extruder is referred to as D0 in your tool definition because it's the first and only extruder drive you've mapped in M584.

Thanks for your help I guess I will go and see how the printer reacts to the new config,
of course it will be the first test
never tested the pizeo either most likely will be an adventure

I finally got things connected and have run the duet web.
I haven't tested motors and heaters yet but wanted to check on a couple things
The probe in duet web shows 1000 and then 0 when tapped is this correct
also the bed thermistor shows 9.3 %c that doesn't seem correct.. its a 120v keenovo
heater...Thanks gary

M305 P1 T100000 B4138 R4700 ; Set thermistor + ADC parameters for heater 1B4138 is the defaul value in the configurator. this value will almost certainly be wrong for you.
you need to find out which thermistor your hotend and bed are using. then look up the beta values for those thermistors. -

I think its an ntc 100k
hot end is a ed3 v6..Thanks gary

I made these changes and seem to be getting a close temp reading when cold 24 - 25c on hot end and bed.
I have a duet wifi also on my delta and it's been running good for a while and that's around the same cold temp i'm getting there.; Heaters

Add
I1to yourM558so the probe signal is low when not triggered and high when triggered. -
genuine e3d use semtic 104-gt2. the correct settings for that are T100000 B4725 C7.060000e-8
-
Thanks
I added the I1 works correct now 0 then 1000 when triggered..
also changed M305 to T100000 B4725 C7.060000e-8
as suggested works but getting the same cold temp readings as I did with my old settings
maybe it will read better when I test the heater that's the next step..Gary
