right, thanks for the quick reply, this makes slightly more sense to me now.

the issue i am having is my CAM (fusion 360) and post processer arent alligned with my CNC router setup, so when i tried to cut my first job the first movement the router makes from the home position starts heading to the other end of the Y Axis and ii get the following error:

3/17/2021, 5:22:18 PM M120 G91 G1 X-10 F6000 G90 M121
Error: G0/G1: target position outside machine limits

is it easier to change the config of the duet or the parameters of the post processor and fusion to be aligned with my router?

some confusion on my part on a previous post so deleted and reworded.

looking for some advice on the positioning of End stops in relation to axis minimum and maximum.

i have my end stops set up in the following configuration:

X- Low End
Y- High End
Z-High end

they were set up in this orientation rather than the standard due to access for loading stock and tool changes.

i'm getting an issue when homed that my tool position reads :

Tool Position
X 0.0
Y 1400.0
Z 120.00

Y/Z should read 0 when homed shouldn't they, if end stops are configured this way?

config.g:

; General preferences
G90 ; send absolute coordinates...
M83 ; ...but relative extruder moves
M550 P"Lead 1510" ; set printer name

; Network
M552 P0.0.0.0 S1 ; enable network and acquire dynamic address via DHCP
M586 P0 S1 ; enable HTTP
M586 P1 S0 ; disable FTP
M586 P2 S0 ; disable Telnet

; Drives
M569 P0.1 S0 ; physical drive 0.1 goes backwards
M569 P0.3 S0 ; physical drive 0.3 goes backwards
M569 P0.2 S0 ; physical drive 0.2 goes backwards
M569 P0.4 S0 ; physical drive 0.5 goes backwards
M584 X0.1 Y0.3:04 Z0.2 E0.5 ; set drive mapping
M350 X16 Y16 Z16 E16 I1 ; configure microstepping with interpolation
M92 X401.69 Y401.57 Z400.76 E401.50 ; set steps per mm
M566 X300.00 Y300.00 Z60.00 E900.00 ; set maximum instantaneous speed changes (mm/min)
M203 X2500 Y2500 Z1000.00 E3000 ; set maximum speeds (mm/min)
M201 X400.00 Y400.00 Z50.00 E400.00 ; set accelerations (mm/s^2)
M906 X2100 Y2100 Z2100 E1400 I30 ; set motor currents (mA) and motor idle factor in per cent
M84 S30 ; Set idle timeout

; Axis Limits
M208 X0 Y0 Z0 S1 ; set axis minima
M208 X730 Y1400 Z120 S0 ; set axis maxima

; Endstops
M574 X1 S1 P"!io1.in" ; configure active-high endstop for low end on X via pin !io1.in
M574 Y2 S1 P"!io2.in" ; configure active-high endstop for high end on Y via pin !io2.in
M574 Z2 S1 P"!io5.in" ; configure active-high endstop for high end on Z via pin !io5.in

i have tried switching my mimima and maxima values around but this makes no difference, if its possible to do this would all of the HomeX.g/HomeY.g/HomeZ.g and homeALL.g files need to be changed also relative to the home position on the axis being 0 rather than 1400 as currently shown?

@UcantCNCme

Can anyone tell me which line in this GCode is sending the router off to an unusable section on the work area?

also what gcode do i input to set the current co ordinates as the start position (stock point) of my workpeice.

@Veti thank you I'll give this a try later

I'm a newbie to the world of duet and CNC, I have a lead 1510 with duet 3 6ch MB, I've built an enclosure in an attempt to keep by electrical components free from dust as I'm working with a lot of MDF.

I've fitted some 80mm dust filter covers over the fans.

May be Overkill but I'd like to use two PWM 80mm fans to cool the board under normal operation. Is it possible to control the speed of the fans directly from the duet using gcode? One fan blowing in at the bottom of the enclosure, one out at the top.

I.e run fans at 50% speed on power on, run at 100% speed when steppers are in motion with a run on timer for 30s as an example so fans aren't constantly switching speeds.

If this can't be done via gcode, could I use a pc fan governor with a thermostat for control fan speed based on temperature inside the enclosure or at the probe if mounted on/near the steppe drivers on the board.

I've purchase a 12v thermostatic switch with a probe I'd like to mount on the board near the stepper drivers. Can this be wired to the duet and the PWM fan speed be controlled by this?

ah right, good to know, thank you very much for your help. i need to start another thread regarding my XYZ touch probe now, hopefully i can get this thing up and running!

apologies your right, that m,st of been the version during the config, heres the M115

3/15/2021, 10:15:36 PM M115
FIRMWARE_NAME: RepRapFirmware for Duet 3 MB6HC FIRMWARE_VERSION: 3.2.2 ELECTRONICS: Duet 3 MB6HC v1.01 or later FIRMWARE_DATE: 2021-02-11

i thought it had updated but just checked the config file and its still reading 3.2.3, retried to update firmware and my DWC is sticking on a grey screen.

ive home again and looks fine, thank you for you help, was the issue to do with the firmware do you think?
