Re: [Emc-users] X-NUCLEO-IHM03A1 stepper controller
There is remora code for the nucleo and the cnc shield. Not sure about the linked board. I think you can talk to the nucleo over ethernet using an external board. I haven't tried it. You can ask Cakeslob on the forum.

First: That boards purported intelligence will sure as tunket get between lcnc and its synchronized multi motor control, which will likely cause problems for linuxcnc. Second: the site does not have sufficient actual data to confirm or deny that. Claims are propaganda, we need facts and those are well hidden. Photos are just enough out of focus to hide stuff. What I have found that works very nicely, is the recent crop of closed loop stuff. It does away with PID's in lcnc because its in the driver. They are setup in hal to do exactly as the TP outputs, and if the motor can't do it, it can shut lcnc down in the next millisecond. The pid is internal to the driver and its motor power is controlled by the magnitude of the error on a step by step basis, 95% of the time the motor is running quite freely on most machines so the error and applied motor current are low, the motor runs with very little heating, and that is a power saving you can see in the speed the utility meter is spinning and you pay for. My sheldon lathe is running them for almost 2 years, half the 4 motors on my 6040 mill (Z,B) have been converted a year ago, the A axis on my go704 is, and the three main axis conversions to them is on order. The 4 older conversions that can stop lcnc instantly have been well tested, it works as intended, but in over a year, they have yet to do so during a job, they simply do what the TP tells them to do. The drivers cost a little more but I suspect since there is no current settings, if an impending step skip is about to occur, it simply bangs the motor with the whole power supply so it makes the move while avoiding the impending skip. Another advantage is that the drivers from Hanpose for both nema 17 and nema 23's & 34's, are rated for up to 90 volts, doubling the speed you can get from that same motor on other brands of drivers rated at 50 volts and running on 45. All of which means faster, more accurate machining that uses less power to get the job done. What's not to like?
