How to ignore Commands

[iplayfast]

I've got a project that is a sand table. The idea is a ball bearing is dragged through sand on a tabletop. This works fine, however, I want to send it 3d printer gcode files, where there are move relative commands or other commands that grbl doesn't know. It gets stopped in its tracks. What I would like is an option where any commands it doesn't understand it is just ignored. (z axis, heater and so on).

Do you think this is possible?

If those commands does not produce alarm or crtical errors on grbl side then those can be ignored on the gcode sender gui you are using

I don't completely understand what you're describing, but unknown grbl commands can be formatted/removed prior to sending them to grbl (i.e. on the host layer). The simplest method is to format non-g-code commands into comments '(' and ')'.

Yes I know that is one option. The request was to ignore unknown commands in the grbl firmware. I'm getting critical errors, when sending 3d printer gcode to the grbl. I think it has to do with temperature settings. Which now that I think of it, ignoring wouldn't help, because the code sender waits until the proper temp has been reached. I think this issue should be closed. Sorry for wasting your bandwidth.
