Does the -P card come with the usb connector for power? or do you have
the dual port card?. My plans are to have 4-Axis machines using
steppers and Quadrature encoders. In addition I would like to control
the spindle speed and synchronize it for threading. I intend to have

I am currently using EMC2 using a parallel port connected to a Gecko 540
driver to control a 4 Axis Mini mill (Seig x2 with 4 rotating table).
I am also in the process to fitting an X3 with steppers and ball screws,
rotating table etc to make a larger 4 axis desktop machine. While I am

Does HostMot2 work over the usb port? Can I use both StepDir and

one computer? How does the performance of the system compare between
HostMot2 and just software generated step and direction?

Can you (or any others) tutor (Or point to some reference reading) on
how the the hardware and firmware of these Mesa boards can provide step
pulses faster than the parallel port? My simple mind says the board
needs the step commands first, how can it direct the motors if it is

An interpreter tucked in hostmot?
No, hostmot2 is way simpler than that.
The interpreter eats G-code and emits a sequence of waypoints (sort of).
The hostmot2 driver takes in those waypoints and commands the FPGA to
step (or run the servo) appropriately to

Actually much simpler, really just an accumulator that has a number (the step
rate) added a high fixed rate (many MHz). When this accumulator

After G-code and before hostmot2.. What is it? (Please excuse my
lack of experience...)
It makes perfect sense to me that The Field Programmable device could
accomplish a hardware/firmware improvement this way.
But how does one control the way

Your explanation makes perfect sense, and was my first guess. But my
mind says such an accumulator must wait for process. There must be gaps
in my understanding.
Sebastian's description/explanation allows for projection of motion

Are step and direction pulses present at the parallel port just ignored
in this system of Mesa Cards and Hostmot2 ?
When using the 7i43, emc2 does *not* make pulses on the parallel port.
Instead it sends commands via the parallel port to the 7i43 (which
*does* make the

Understanding is a wonderful thing.
