I changed the g92 to read X550 Y770 Z94 and that cured my problem. Looks like it over rides the M208 in the config.g.
I will call ooznest tomorrow to see what its there. Thanks for the guidance, I wouldnt thought of looking at homeall.g

WHen I do M208 S0 it gives me x550 y770 z94. after homing I get the same answer but when I watch the head position indicator as it is homing. the figure goes to 770 and as soon as it homes it changes to 520. Im not sure why the G92 is in the homeall but the note says change to machine size. I will go do that and see what happens

Ive just noticed the G92 command in the homeall.g looks like that could have somethiung to do with it. Not seen that before

I just got OK after sending through console. config.g below shows where I tried the new M208 method, I rem'd out the normal.

Hope this is OK

Following a lot of problems with my Duet, particularly connected with the Wifi, I decided to install the latest firmware from duet and ooznest. as a result the y axis will now not travel beyond 550 on my 550 x 770 table. I have ensured that config.g contains correct M208 coding i.e. M208 X550 Y770 Z94 S0. I have also tried the new coding for firmware 2.02 i.e. M208 X0:550 Y0:770 Z0:94. None of these had any effect. I still get an out of range error going beyond 550. I have even input the code via YAT with no effect. Not sure what to do next. I have checked the config.g for anything out of the ordinary but nothing different. As the coding has changed for this version of the firmware I wonder if there is a problem with it

For those interested in changing post processor for Vcarve. I got this instant reply from Vectric

You cannot use " marks in the list of commands as these are used to tell the software that this is where a line begins or ends.

On Page 28 of the Post Processor editing guide this is described in more detail.

For example the line:
M291 P"Have you set work coordinates ?" S3.

is replaced with

"M291 P[34]Have you set work coordinates ?[34] S3."

Thanks Vectric for that.

Firmware is 2.03 beta1

I think ythe firmware is 1.22.2 it seems to come with the Workbee firmware V1.0.3.
As regards Vcarve gcode. I have added several small commands which control my Router on/off with no trouble at all. I found the send message (M291) command in the Vetric post processor manual which I followed to the letter. Recon it would accept quated strings but will check to see if the version I have is OK for that

Have just checked all the endstop wiring and made sure that it wasnt in a position where it could get caught. checked each home position separately and did Home All and everything is now fine. Looks like you are right. Thanks very much.

It is possible that one of the endstop wires is getting caught and shorting when I home. Will check that in the morning

Yes, Ive had the machine working for sometime but unfortuneatly damaged my Duet car and had to get a new one. Now I have the problem.

@dc42 Thanks for that.

I am attempting to alter the vcarve post processor to ask me to ensure that I have set work coordinates before it starts to cut. This prevents my router diving into the spoilboard if I forget.
The code I am trying to insert is:
M291 P"Have you set work coordinates ?" S3.
Unfortuneatly I get an error " expecting 'begin SECTION ' or 'end SECTION' when I run Vcarve. Does anyone know why ?

I recently received a new Duet which had been set-up for me to create its own WiFi access point. All works fine with the exception that every time I Home All, the Wifi signal dissappears. The only way I can bring it back again is to connect my laptop via the USB port, without doing anything else. I dont know whether it restarts because I am connecting through YAT or that the card has a 5v fault which is restarted when it picks up the 5v from my PC. Has anyone any idea ?
Thanks

The modification to the post processor is also quite simple just add the M106 commands in header and footer. works perfectly for me also controls my dust extractor

For me the solution turned out to be very simple. I used the fan0 connector and controlled it using M106 ie M106 S1 to turn on M106 S0 to turn off ( Fan0 being default) Works perfectly. All I need to do now is get the command, plus a short delay while the router runs up, into the Vcarve post processor. If anyone out there can give a pointer it would be appreciated.

Thank you. I will have a go and let you know when I get stuck

@dc42 Thanks for the very speedy reply. Are the fan pins 24v ? or do I have to change relay

I have a WorkBee CNC router controlled by a Duet. All works fine apart from the human element, namely I have to remember to switch the router on via its mains switch. On several occassions I have started a cut only to watch my router dive into the work and almost destroy the WorkBee because I have forgottent to switch the router on.
My plan is to control the router on/off with a relay control which I have already made. All I need now is a 24v or if necessary 5v source controlled by the Duet. Im considering picking up the 24v supply from heater 0 ( the 18amp). any controllable source will be OK.
All I need is guidance on what M codes to use to do this. I intend to put these codes in the post processor of VCarve Pro.

Thanks in advance

I Have found the socket on RS. I have the tools, not sure about my eyesight but will have a go I think
