Have a CNC with Richauto A11 3-axis DSP using DMA860H drives with a push button on the x-axis to do rotary work if needed.
1. Aspire 9.5 claims to be able to do 4-axis now. Is that true?
2 If true on Aspire 9.5, does it makes sense for me to upgrade to Richauto A18 4-axis DSP, add another DMA860H drive and rewire the push button to handle the c-axis?
3. Would I need a reset switch for c-axis when doing the go to home position on startup? Not sure how this would work.
4. Is there any recommendation of where I could get the DSP and drive in the US?

Thank you in advance for any guidance I can get from the group.

Sincerely,

Asim
