Re: Rigid Tapping Question
Yes, I checked back through previous NC files generated in Fusion and no matter what settings you choose, it uses F, not Q. There's even a check box in the Fusion PP for "use feed per rev" but this still outputs G84 with F. My machine doesn't have spindle positioning, so I have a tension c...

Re: Rigid Tapping Question
I've generated rigid tapping from Fusion no problem. I'm away from my machine right now but could it be that you need to select "use canned cycles" or similar within Fusion CAM?
You shouldn't need to edit the PP to get this working. I'll see how I did this later when I get back....

Re: New Build, PM2700 lathe with Acorn, Videos and Photos <upgraded to AC servos>
Thanks. I've seen that thread. I think it might answer my question but just to be clear: it doesn't matter that the motor has a small gear on it and the spindle shaft is larger. As long as I have a 1:1 ratio from the spindle shaft to the encoder, the ratio of motor:encoder is irrelevant, correct? T...

Re: Rigid Tapping Setup
It's not recommended to put large capacitors (total 200nF in this example) across the output of an opamp. In the case of the LM4324, that max recommended value seems to be around 100pF and certainly below 500pF (where the phase margin becomes zero). It's not going to be possible to define how the de...

Re: Solidworks for $38.50 a year
The CAM integration is great, and I'm not stuck with a several hundred dollar bill annually. What CAM are you using with SW? At one point they were giving HSM Works 2.5D for free with SW but then HSM was acquired by Autodesk and it now forms the CAM elements of Fusion and Inventor. I'd assumed the ...

Re: Safe Spindle Temperature?
Those marks are suspiciously evenly placed, which perhaps suggests they are due to a spec of swarf or metallic particle. If so, they may be built up rather than worn away (ie convex rather than concave). Take a closer look and also use a sharp blade to determine which it is. You may well find they c...

Re: Intercon enhancement request
As stated airblast / mist / flood aren't adequate on deep cuts up to 3 x cutter diameter. (Not to mention the unwanted mess of high pressure airblast.) Almost all of my cutter breakages have been due to inadequate clearing of chips, resulting in recutting / welding. The choice seemed to me to be be...

Re: Solidworks for $38.50 a year
For me, the one-time purchase price of Alibre and Vcarve makes more sense for someone retired. I look at it with a 10-20 year lens as for the total money spent. Fusion's current price increases makes me sense that I chose correctly, but to each his own. Obvs it depends what you are using your CAD a...
