Is this dead or will there be an update to 1.1h?

Hi All,

Just wondering if this Is dead or will there be an update to 1.1h?

[marlboro]

This must be dead given the lack of responses, but let's bump it just in case.

Hi all,

grbl-Mega-5X,direct fork of grbl-Mega is still active and maintained.
Last version from may, 10 is 1.1t.

@++;

@fra589 Thank you for the heads up! That is exactly the kind of advice I was looking to find.

My trouble, @fra589 , is that you wrote it exclusively for the RAMPS board. I am not using RAMPS at all; I am using a Mega 2560 R3 in my rebuild/ upgrade of my CNC plasma table -- therefore, it is useless to me even though it offers features that I need.

My table was a regular 3-axis table, running GRBL-Mega. I have added a 2nd Y-axis which must be cloned with the 1st Y-axis and both Y-axis's must home together while auto-squaring. I also use a torch height controller of my own design that is fed from GRBL's Z-axis using an interrupt to intercept step/ direction signals from GRBL and either pass them through to the stepper driver unaltered or send its own pulses to the stepper driver while receiving the ARC OK signal from the plasma cutter.

I am using external DMA860S drivers for X, Y, & Y2 axises & an external DM556 driver for Z-axis -- so I cannot use the RAMPS board at all. Would you possibly be willing & able to add a #define CPU_MAP_2560_INITIAL section to the cpu_map.h file with the following #defines that match my build?
