eastworld Posted May 21, 2018 Share Posted May 21, 2018 I have an Expo Zircon drill which until recently was powered by a Minicraft MB730 controller. Thiscontroller recently stopped working so I am looking for something to replace it with. I have tried a Proxxon controller but the minimum speed seems very high (much higher than the Minicraft). Just wondering if anybody had a recommendation? Stu Link to post Share on other sites More sharing options...
DCB Posted May 21, 2018 Share Posted May 21, 2018 If it is 12 volt DC 1 amp you could hook it up to a Morley or OnTrack controller's track output to give pretty much as slow a speed as you need. They go way down below 1 volt minimum even off load. Don't try this with a Autotransformer or a PWM or resistance controller. Link to post Share on other sites More sharing options...
