I'm just about done setting up my Blackbox X32 and try somethings out. I'm coming from one of those $40 woodpecker clones and it worked well enough for a year on my DIY machine. I built a V2 of it inspired by the Sphinx and I thought a X32 would be the best choice. My current spindle is one of those 0-100V brushed 500w ER11 jobby. I've tuned the X32 0-10v as well. What's happens is when all powered up the spindle slowly turns at maybe 100rpm. If I pull the 0-10v connector it doesn't change the behavior. Plugging in the potentiometer that came with it causes the slow turn to immediately stop. So it's not the X32 for sure. It's like the driver needs something to kill the residual voltage that the X32 isn't doing. The weird thing is the cheap controller I was using did seem to have enough resistance to stop the motor completely. I wanted to see if anyone might have some suggestions for me to remedy this. Aside from get a VFD spindle I do have a brushless spindle on order incase but it comes with it's own problems. Thanks. Steve
Normally spindle controller allow setting up Min RPM. But those cheapie DC motors with a collet on them, might not have the required feature. Plug its PSU into an IoT relay docs:blackbox-x32:connect-dewalt-iotrelay [OpenBuilds Documentation] alongside the 0-10v speed control. The IoT will control start/stop
Thanks from taking some time to reply and offering suggestions. I found an additional inexpensive and a more expensive alternative for anyone else running into this. The first was to re-use the PWM to 0-10v adapter I used on my old rig. I switched from the X32 0-10v output to the PWM and fed it through the old convertor and that worked great actually. I picked that up on Amzn for like $10 or $12 some time back. The other option is to use the hardware from one of those brushless spindle kits. Definitely more wiring needed but it's quite a bit quieter and works good using the X32 0-10v output
