2 thoughts for consideration:
With the due and the mega both running now, would it be worthwhile to go through the mega firmware and make the settings match the due? This would essentially be more of a GRBL 1.1 update on it so the two systems are similar. Such as Matching the baud rate and the variables. Make them “speak the same language.”
Work on the Mega firmware to get similar movement compared with the due… soft start / stop. This would mean changing some of the mega movement routines and attempting to incorporate the magic sauce that is in the due, but for an 8 bit processor.
This are not intended to be philosophical “is it possible” questions, but more of “would anyone find value in it?”
I think the mega isn’t fully utilized. The due is underutilized in its use for maslow. By revamping the mega firmware to be more like the due, many of the “upgrades” would become a flash and not buying a new controller. I think all this M2 upgrade hype is over the simpler z axis rather than an improved controller and the promise of universal software that is better than what is available. This has not yet been realized though some are slaving away to make it so. I’m trying to consider “the rest of us.”
Progress on webcontrol has apparently come to a screeching halt as of June and progress on the mega firmware stopped about a year ago though there are several pull requests that have not been processed. I’ve merged a number of the changes and added a couple features (spindle speed control, as well as some that others have added such as z end stops, correct chain length, and a few others) that I thought were interesting into my fork of the firmware, but I think there is still more that can be done.
Just casting this out to see what hits it gets and if anyone cares. There are some firmware tests and bug fixes likely needed to proceed and a few more eyes on it would help. The classic maslow is a very capable system and I think it can and will serve many for many more years and should be maintained and upgraded.
