Looking around, sure enough I do have some of the backwards (solder "pyramids" in towards the extrusion.). Should be an easy fix when I...
Adding a rubber washer under the head of the screw securing the limit switch to the c-beam eliminated the issue. Question: The LED is still green...
Both Z switches are right-side up, with spacers, and all wiring is right. If I unplug the lower one, the Spindle isn't grounded. Could the switch...
I edit my post as you wrote yours - the Z limit wire is the bad ground. Thanks again Peter.
Cheers for this Peter. Regarding the tensioned leadscrew setup - I already have all of those parts on hand. So the basic idea is just to add a...
I am retrofitting a Chinese Ebay 1m x 1m CNC I obtained from an older gentleman in June who wasn't interested in the CAD part of CNC work and...
Any update on this idea? It’s a nice feature of both ShopBot control and Mach 3 software that would be useful in OBC.
That's a good idea - better than my aquarium pump in a 5 gallon bucket. I have to run RV antifreeze insteead of water for the next few months...
I'd like to add a coolant temperature sensor to my build so that the program initiates a feed hold, shuts down the spindle, and raises the tool...
Wow that is AMAZING!
Peter - Can you detail why it's important to program the VFD minimum frequency at say, 7200 RPM (120 HZ USA)?
Yes! We are also building one of those swing arms at the makerspace I founded (Truckee Roundhouse) over our ShopBot. Great design. I might start...
All good tips, thanks! I am staring at how I am attaching and wiring all of these things (VFD, power supply, Black Box, 4-gang box, VFD Spindle...
Thanks for holding my hand through this Peter. I hope gaining this knowledge doesn't cost me another $200 for a second Black Box!
So you're saying there is an internal 24V pullup to X1 within the VFD, not on the external terminals, that was activated when it was in RUN /...
You know how you wake up in the middle of the night thinking about these things.... While I do understand that if I had connected a jumpered X1 /...
Yeah the motors and spindle work as expected. And if I’m not utilizing DIR anyway maybe I dodged a bullet. What else would I keep an eye out for...
Whoops. Am I likely to have done any other damage to the Black Box?
I added a single pole switch between COM and X1 and I got the spindle to work with M3! It also stops when M5 as long as the switch stays on, but...
I was able to reestablish the old BOB with Mach 3. The relay is NO with 18v between X1 and GND. There are 25.5v between x1 and COM. When M3 is...
