Forgive me if this question is off topic.
Jeremy, that is a great piece of work.
You mentioned that you used the Shumaker suggested servo tester to get the pulses needed to get the motor going.
My question is: Does anyone have experience of driving this type of motor control from the MACH3 software suite?
I know from reading the MACH3 manual that PWM speed control is covered on page 5-7 & 5-17, but has anyone actually done it with a DC brushless motor?
Here's hoping!!

Sorry, I just thought to ask you if you have had any machine time with this new spindle yet?
Most important to me is: how noisy is it?
cheers

Hi Jeremy,
I've just set up an X1 mill with DIYCNC gear. I'm now looking at building a 1mtr x 0.75mtr router. It's been sometime since you made your brushless spindle, I wonder how it's performing? I wondered about using a watercooled esc if heat was a problem.
Very useful thread.

This is very interesting. I've already constructed a gantry type mill and am using a Kress router to mill non-metals. I'm now looking at ways of milling non-ferrous metals and manufacturing a spindle motor for this purpose. One component of the spindle I'm having difficulty sourcing is the actual spindle/collet holder - from where did you get yours please. I've sourced a suitable motor and have decided upon a step-pulley belt drive system in order to achieve good torque at low speeds.

Hi miopicman , has Jeremy used an air die-grinder as a base for his spindle?

ER11 C8 100mm straight shaft ebay... 8mm shaft (good for mounting straight through a sutable brushless motor)
C10 10mm shafts are like rocking horse s**t
C12 12mm shafts are more common
