M350 X32 Y32 Z32 E32 I0 ; Configure microstepping without interpolation

why would you not enable interpolation?

M584 X0 Y1 Z2:4 E3 ; two Z motors connected to driver outputs Z and E1

https://duet3d.dozuki.com/Wiki/Gcode#Section_M584_Set_drive_mapping
you ignored the section about the order

M92 X200.00 Y200.00 Z200.00 E420.00 ; Set steps per mm

Z200 is most likely wrong and the reason why your z axis is moving so slow.

If you have a 4 start T8 leadscrew, you need Z800

Thanks think I have the 2 motors working ok and the x and y now

I have one issue I thought I had it setup to use the probe for homing
that doesn't seem to be working..

I do have a home switch on the z also that is working but not the probe as a home switch..
so I must be missing something there also..

Ok thanks M92 go's after M584 from what I am reading

also when I home x or y the Z move down a few mm then the x or y homes and the z moves back up a few mm is this normal?.

Thanks gary

dont use switch + probe. it just makes it more complicated.

yes its the default for files generated from the configurator.

@veti
so I am assuming now I remove the Z1
from M574 X1 Y1 Z1 S1
I modified the homeall and homes
and added the G30
Haven't test but will tomorrow..

Thanks

you change it by adding
M574 Z1 S2 ; Set endstops controlled by probe

Thanks that worked OK do I need to set G92 Z0 also

also it looks like my extruder is set correct but I get no movement
I sent a g302 p1 first but no motors
getting the message attempting to extrude with no tool selected..

I have tried g01 e100 t0 but on luck..
So guess I have something misconfigured again..

It does look like the E0 endstop is on yes..
could that be the problem..

add this to the end of your config.g

; Miscellaneous
T0 ; Select first tool

Thanks that worked OK do I need to set G92 Z0 also

no that makes no sense. what kind of lead screw do you have?

gorf26

its one I had laying around if I remember right its a 3/8 - 12

I have the z motors moving haven't checked if they are moving the right distance yet but they are moving together...

I did get the probe to work for z home also, but I don't think it set the bed to z0

my main problem right now is no extruder movement even with a m302 p1

if I check the status it shows that the E0 switch is triggered..
I assume that's my problem I just don't see anything in the config that bad
but I still learning..

well guessing is not going to cut it here. you need to know this exactly to calculate the steps per mm or you wont be able to print correctly.

@veti

I know that not to worried about the steps per right now I want to get all the functions
working then I'll fine tune it...

and right now the extruder motor isn't moving, and don't see any reason why in the config.

Veti

what the output in the console if you put in G0 E1?

gorf26

Thanks I got it work, was a typo..

So now I will calibrate it..
