Insufficient dynamic range on AMASS #160

Open J-Dunn opened 2 years ago

J-Dunn commented 2 years ago

It seems that insufficient dynamic range with AMASS 0..3 leads to inability to get low feed rates and inaccurate probing due to delays between touch and end of motor movement on 32bit hardware.

This is easily fixed by adding two more AMASS levels. This has no downside and should probably be adopted by all grbl versions on faster processor hardware.

for probing might wan to check this too: https://github.com/terjeio/grblHAL/issues/353
