Dynomotion Forum

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

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...

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

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...

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...

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 phpBB is incredible outdated.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...
