Note these are hot chassis so trying to control speed via your CNC
controller can be a bit tricky, since you'll need to galvanically isolate.
We've talked about this [ad nauseam some may say] before on this and the
Taig forum, and I recently found out that other, actual spindle BLDC
from other vendors have similar issues of hot chassis. My day job was
looking at getting a packaged CNC from some industrial CNC shop that
retrofitted Rong-Fu style machines. During a conference call the sales
engineer mentioned the trouble they went thru to allow their CNC
controller access to varying the spindle speed.
Since I don't have a tool changer, I really didn't feel I needed to have
Mach 3/4 change the speeds for me.
Note that the newer CSM Consews are a bit different than the CS version
I have. They went from using an LDR and LED to using a hall effect pedal
control, as well as simplified it with a smaller uC based on the ST
Microdevices BLDC reference design. this was due to the core customer
base (actual sewing machine applications) not digging the acceleration
profile; esp the low end control.
I've been using mince for about 4 years now, on jobs lasting many hours
and have no issues so far.
