Re: Stepcraft HF Spindle

Thanks Tom, good to know.

I think I've got enough info to get this hooked up properly. I'll let you know how it goes.

Thanks again and have a good weekend :)

Re: Stepcraft HF Spindle

Hi Tom, Thanks for the info. I've had a look inside the spindle electronics and it looks like the Spindle On/Off is buffered through a standard NPN transistor, before heading to an ATMEGA16 GPIO pin, so that should be pretty straight forward. The bit I'm struggling with is understanding how you cont...

Re: Stepcraft HF Spindle

What's the most stable 5V supply on the KSTEP or KFLOP?

Re: Stepcraft HF Spindle

Okay, that worked, but it needed both the Spindle On and PWM Signals. I had the 1.5V battery negative to pin 10 (gnd), positive to pin 13 (spindle on), and via the 1k resistor to pin 7 (pwm). So next steps are to wire it up to the KSTEP Analogue output. I think I'll use the same 5v supply through th...

Stepcraft HF Spindle

Hey guys, I've got KFLOP/KSTEP running a 3 axis router. Spindle is a Stepcraft HF Spindle. I set the speed and turn the spindle on manually. As per the table on P18 of the manual, the spindle can be controlled via a 15 pin DSUB, Pin 13 Spindle On/Off, Pin 7 PWM (0-5v) https://www.stepcraft-systems.c...

Re: Welcome to the Dynomotion forum!

Good to see a dedicated Dynomotion forum, although it would have been far, far better on something like the Discourse platform. phpBB is incredible outdated. I would urge you in the strongest possible terms to consider switching to Discourse now, rather than having to do it further down the line. It...
