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.
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

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
