    Dynalink, sorry I missed your message until just now - but @Sterob has it. The speed control is done with that 0-10V signal which should be coming from AO1 with the jumper set appropriately for...

    Re: X6-2200L

    That would be the most blatant "get my minimum post count" post of irrelevance ever!!

    Also, one more supplier that goes on my "I will never buy from this company" list. Well done.

    Re: Treadmill motor/drive help

    IK,R? I went up their page menu from there to DC motors to controllers and found USD264 was the cheapest reversible one they had.

    $10 worth of parts for a PWM source and direction control vs $300 for a reversing controller on that site. It's for a hobby machine. Seems like the exact opposite of a waste of time and money to...

    This was always coming and the main reason I found it difficult to recommend 360.

    Re: Aluminum Chip Welding

    It's a convincing counter argument!

    Either way it's probably splitting hairs: I reckon correct chip load and lubrication are probably more important, and by orders of magnitude more influential.

    Re: Aluminum Chip Welding

    There's an argument that any coating rounds off the cutting edge slightly and that (for aluminium) the sharpest edge outweighs the benefits of the coating. Just putting it out there :)

    Re: Fusion slotting

    Don't plunge straight in, instead, change the ramp type to helix (IIRC it's the default for adaptive paths anyway) and it will ramp into the guts of the cut in a spiral, then work its way out. You...

    Re: 3D Probe - Tri-balls type accuracy & DIY

    That is a thing of beauty, Mecanix. Impressively quick build time too - usually this kind of project takes me months to tickle along in the background. Well done and thanks for sharing!

    Re: F360 - spiral toolpath on 4th axis?

    And yeah, I've played with the wrapping stuff before - it can be enormously helpful in some cases, keeping torque loads on the 4th nice and low by primarily working in close to the axis. And a lot of...

    Re: F360 - spiral toolpath on 4th axis?

    That's not "continuous" 4th axis machining though. It's a lot of 3a operations done on an indexer.

    Meh, it'll get me through until Autodesk release real 4A support on 360. :)

    Gerry, "wrap" is available only for a couple of 2d strategies and it only allows wrapping onto a convex cylindrical form. As soon as the form is non-cylindrical (or, as on one of my ops, on a concave...

    F360 - spiral toolpath on 4th axis?
