Lost Second Y Axis Motor

Was running some parts for the wife who needs this project completed before next weekend. Went to start cycle on the next batch of parts and the gantry racks out of alignment and makes a hellish noise from the front left motor (skipping steps). There's a joint 1 limit switch thrown. Turned off the m...

Re: Super-PID Speed Controller

I have one, but I have a much older Probotix controller (pre-Unity) which doesn't by default have a pin to use for it. Was looking into stealing two of the three relay pins to make it work, and using the third for a touch probe. Haven't gotten quite that far since I'm not all that good at setting up...

Re: Update, Mapping table deviation, wish list.

I currently need to replace the original spoilboard, so have been tinkering with the idea of adding some intermediate ribs underneath and an aluminum extrusion top below where the original spoilboard was. I could then mount a 24" square piece of 3/4" MDF to the aluminum extrusions with som...

Re: Re-homing after a limit switch fault?

And to answer your question on the E-stop... yes it will immediately stop the machine motion and it will not know exactly where it is. If it is not a true emergency situation, use the Stop button on LinuxCNC instead. I learned this the hard way on a very important piece I was working on. I managed t...

Re: Shimming spindle carriage.

Reminds me that I need to do this once I get my power supply in and get my machine back up and running. It's clearly evident when flycutting my spoilboard with the 1.25" cutter. I have shimmed it a little, under the bottom edge of the router mount where it meets the Z axis plate. Apparently I d...

Re: Power supply died. Need to test transformer.

After dinking around with the power supply some more, I'm getting no output at the wires coming into the board from the transformer. Something's gone dead in there. Just placed an order for a new power supply.

Power supply died. Need to test transformer.

Not sure if I'll need to replace the entire power supply, or just the power supply board. Anybody have a diagram showing what voltages should be present on the various taps on the transformer? I want to see if it's still ok before looking at a full power supply replacement. I had just finished flycu...

Re: DIY CNC Dust Boot

I've tried all manner of strip brush. I finally settled with Fun Foam from a craft supply store. It makes an excellent skirt. Mine's in yellow, so highly visible as well.

Re: DIY Corner Clamp Kit

I see a minor issue. You may want to somehow eliminate the dowel in the corner. If you have a larger or smaller box, there's no room for longer threaded rods. Your threaded rods need to be specifically cut for your clamping dimensions. Place the dowel either further out, closer in, or chop out the c...
