I’ve seen a few posts referencing parameters such as #5221 and #5241 for the X offset for g54 and g55 respectively. Is there a list of these somewhere?
So far my searches here in the forum and in google at large have only mentioned a few of the most common results, but I’m specifically wanting to find out if there are parameters that correspond to the machine coordinates so that I can code a custom probing cycle in g code.
these are numbered parameters and are a part of g-code standard. It may be that not all numbered parameters are available on every CNC controller. The Buildbotics CNC Controller has its g-code patterned after the LinuxCNC g-code dialect, and the parameters are listed here.
The coordinate systems G54–G59.3 and their numbered parameters are described here and the corresponding G54–G59.3 commands here.
For moving in machine coordinates, there is the G53 command.
For G53 coordinates, on LinuxCNC and controllers with g-code patterned after LinuxCNC g-code dialect, there are the parameters #<_abs_x>, #<_abs_y>, #<_abs_z>, #<_abs_a> etc. but they do not work on the Onefinity/Buildbotics controller (don’t know for the MASSO, please report). A workaround on the Onefinity/Buildbotics is to use [#<_x> + #<_offset_x>]
Thanks for that. That’s exactly what I was looking for. As for moving in machine coordinates, that’s not what I’m trying to do. I was wanting to be able to probe xyz in a given work coordinate system, record the machine cords, probe in a different work coordinate system and read the machine coordinates. Then compute the midpoint and set that as my new g54 work zero. All I was missing was a way to measure in machine coordinates so that I could compute the midpoint.
