Maybe 7i40? But what’s the problem with using the Pico one?
A good place to look for DC motor drivers is Polulu. Here is what they
have. I bet you can use one from the "mid-power" section.

All of these take PWM and a few pins for forward, reverse brake. These
modern drivers are so good there
After it finally was delivered, testing looks good but now I need a
controller, smaller and lower voltage than one of Jons pwm-servo's.
This motor supposedly turns 220 rpms no load with 24 volts applied.
It has an encoder on the rear which is making a 5.4khz quadrature signal
when its running

That should just be a wiring job. The firmware will auto-detect the
smart-serial card (that's the smart bit)

hey guys I managed to get the mesa cards working. thanks so much peter and
andy for the help
between the two of you I managed to piece it together.
mesa flash was probably already downloaded but I downloaded it again. then
downloaded bit files. found the one peter was talking about and then
So - I kinda cheated. I set up the comp so that I could run a gcode
program and scan the 'radius' of the shape into an array.. SO it looks like
-move to the center of the shape - comp captures center.
-move to the profile of the shape - set the comp to scan mode
-run the gcode and the comp
Johann,
Out of curiosity is it you don't do machining at all anymore? Or some other
solution other than LinuxCNC?
Thanks

Hi guys
How do I unsubscribe?
I dont use Linuxcnc anymore.

It seems that the LinuxCNC hostmot2-firmware package either needs a
bit more love, or needs to be abandoned. It is only making a very
small subset of
just done a whole lot of research and I need to find the correct bit file I
think.
any tutorials out there would be great.
thanks andrew

I get this error Can't find file 5i25_7i77x2.bit
can I just re download it from somewhere?
