G92 code for Y is being ignored
Hello this is my first post so bear with me if this was already posted (I tried to check if someone else had it but found none)
I'm a proud user of a Prusa MK3 which works perfectly for 3D prints, but I also use it with Flatcam to itch PCBs.
In order to set the proper printing area on the PCB I use G92 codes to set as zero the current pos.
On later firmwares it was relatively working but on latest it's ignoring G92 code for Y.
The Z and X are properly set to 0.
Any ideas why? (copying here the first part)

Sorry can't help with G92 other than to say the G92 description has comments about restrictions.
Very interested in making PCB#s on my 3d printer. Could you post a description of the process and perhaps a few pic's showing resolution. Thanks in advance.
I follow the same principles as in this page: http://www.lamja.com/?p=635
I works pretty decent in terms of resolution, its a little more complex when dealing with two sided boards.
For the time being I'm positioning the tool in the required position and reset the printer, since G92 is ignored for Y axis.
Any idea on other gcode options?
