Found ic codes.. the mosfets can upgraded with better easily.
But in general needs optoisolation / overcurrent protection / enable pin / higher clearances in copper traces and better mosfets

7402 seems to have daisy chained NOR's, it should be possible to disconnect some and use for enable.
And for higher voltage, something must be done for MC34063, probably cutting the trace and supplying another 15V to it separately.

I like to use 180lpi linear encoder, my question is, linuxcnc count all four transitions on phase A and B. Because if only one count is used, we have 25.4/180=0.14mm resolution, and have to adjust DEADBAND to 0.14 finally only 0.28. In the other hand with 4 transitions counted have 0.035 and adding DEADBAND 0.07. Is for woodworking cnc. Thank

What is the question?
Is any of those settings working properly for you?

Yes, LinuxCNCs encoders (software or hardware) usually default to 4X quadratureI like to use 180lpi linear encoder, my question is, linuxcnc count all four transitions on phase A and B.
