Same lathe as Busy Bee B2227L https://www.facebook.com/marketplace/item/1364107434723917/?

Lord, aim all 8 of them through a fresnel lens and you could probably use them to weld aluminum.

Try throwing a 50k ~ 100k resistor between collector and base. This should trigger the transistor whenever the probe is disconnected, but probably not be enough bias to offset the probe output when the probe output is triggered and goes to ground.

Fairly simple solution. The probe output is <Hi> until it’s triggered. Feed the probe output to the base of a medium power NPN transistor, TIP31 or similar. As long as the out put is Hi, the transistor is conducting. Run the tool setter in series with the transistor collector, emitter to ground...

Active sensor has three wires? If so, simple mod to add a relay to output the appropriate signal to be the same as your existing NC tool setter, then wire the relay output and tool setter in series. What’s the part number of the active sensor? What is your supply voltage? Get me that and I can...

Ten minutes of digging in the fastener buckets. M6x60 socket head cap screw, M6 wing nut, and replaced the movable jaw tightening fastener with a hex head cap screw.

Welcome from Vancouver!

Welcome from Vancouver! Just finished my most recent mod to my Dahlgren Series 300 engraver, now running a hybrid Estlcam CNC controller & software with a slightly hacked pneumatic spindle actuator. Also have an original New Hermes manual engraver, a 3018 cnc, and a Squink pick&place SMT...

Off on a tangent - I understand that when I sell something on eBay, I should be claiming that as income. However, what about reality - I bought a Busy Bee CT129 mill in 2010 for $1500, over the next 15 years I spent thousands of dollars on tooling, then sold it on Marketplace for $1000...
