No Axis Movement

1d1

Trying to install Duet 2.0x Wifi board on small delta. Extruder and heaters working fine, but zero axis movement otherwise. Have tried different directions, end stop switches working on proper axes and system was totally working before install of Duet. UI indicates n/a on all three axes. I'm lost. Here is my config.g:

you have set up the homing? it will not move before its homed, set with G92 or overriden with M564

1d1

Just tried M564 G92 directly - same message and still no movement. Should I put this in config?

M92 X80.02 Y79.94 Z80.07 E2650.00 ; set steps per mm

on a delta x y and z should be the same.
your e steps look very high. what kind of extruder do you have?

; Z-Probe
;M558 P4 H5 F600 T9000 I1 ; set Z probe type to switch and the dive height + speeds
;G31 P25 X-2 Y-2 Z20 ; set Z probe trigger value, offset and trigger height
;M557 R100 S40 ; define mesh grid

if you have no probe you need to define a P0 probe

M305 P0 T100000 B4138 R4700 ; set thermistor + ADC parameters for heater 0
M305 P1 T100000 B4138 R4700 ; set thermistor + ADC parameters for heater 1

B4138 is incorrect. you need to find out which thermistor you are using and set the value for it.

M579 X1.012 Y0.9871

why have you set this?

for you movement. have you correctly identified the motor phases and connected them accordingly?

1d1

I'm using someone else's config, however, modified. E steps are for Zesty Nimble V1 and correct (30:1 gearing). Individual towers are calculated by the imported config - I'll change them to 80. I have a probe, but was trying to eliminate extra stuff until movement happens. B4138 matches room temp and has been working fine on another printer.
I have no idea why M579 is there.

1d1

Oh yes, motors wired properly.

Veti

@1d1 said in No Axis Movement:

B4138 matches room temp

that is because most thermistors used in 3d printer are 100k at room temperature. it does change at higher temperature and could easily result in temperatures being off by 40C

Just tried M564 G92 directly -

those are 2 different commands

1d1

Yes. I tried individually and separately. Not worried about thermistors right now. Thanks for your help. I appreciate your time and thoughts.

Veti

what parameter did you use for M564 ?

1d1

Perhaps my board is boinked?

1d1

For M 564 I just tried "home all"

i dont undestand what you mean

M564 requires a parameter. on its own it does nothing.

bearer posted a link to the documentation. if you had read that you would have seen that you need to issue

M564 S0 H0

edit: It states
On some types of printer (e.g. Delta and SCARA), movement before homing may be prohibited regardless of the H parameter.

Veti

can you post your homedelta.g ?

1d1

I entered M564 in the UI Gcode console, then tried to home. After sending the M564 it told me that movement outside the bed not possible, but homing was.
As for documentation link, I didn't and still don't see one. I'll add the M564 S0 H0 to the config.

Veti

@1d1

look at bearer's post. the commands G92 and M564 are links.

is there a response when you send G28?

1d1

No action with the M564 S0 H0 in either config.g or homedelta g

Veti

@1d1

no as i posted thats not allowed on a delta

1d1

I'll try it. Didn't realize those were links....

1d1

Movement! Not the correct movement, but all three axes moved From G92 X0 Y0 Z0 with the extruder at the bed, and centered.

M574 X2 Y2 Z2 S0 ; set active high endstops

Have you got active low (normally open, or NO), or active high endstops (normally closed, NC)? See https://duet3d.dozuki.com/Wiki/Connecting_endstop_switches#Section_Microswitch
If you send M117, and the endstop reports triggered already, it may explain lack of movement. Change S0 to S1.

If you change anything in config.g, you need to reset the board, or send M98 P"config.g" to use those changes. Or input gcodes (temporarily, until the next reset) in the gcode console/command line.
