Issues with Custom G-Code in Matter Control
-
Matter control appears to be adjusting my custom G-code. This seems to happen in both End g-code and cancel g-code.
My cancel G-code is below:
M104 S0 ; turn off temperature
G91 ; Enable relative mode
G1 Z10
G90 ; Back to absolute
G1 X10 Y200
M84;
However the G91 is never sent to the printer only the G90.
If i simplify the G-Code down to
M104 S0 ; turn off temperatureG1 X10 Y200M84;Then matter control seems to send G1 Z10 Y200 Z0
I can't come up with any reason why it isn't just sending the commands as typed, if I send them via the terminal they do exactly what I expect, but when mattercontrol auto executes everything goes weird!
Any suggestions?

There's a couple of facets to this issue.
First, MatterControl does filter G-Code and make changes to certain commands, G91 included. Check this page for more information about exactly what changes are made: http://wiki.mattercontrol.com/G-Code_Filtering
Second, the G91 change should work but as @unlimitedbacon pointed out to me as he tried to run your code to reproduce the problem there is no feed rate specified in your G1 Z10 command; the error "Error: Undefined feed rate" was thrown. Specify a feed rate with the F parameter, so:
G1 Z10 F5000or something like that. Your code should then run just fine.
