Configuring UCCNC for Fusion360 (mm scale)

Postby LBayZG » Mon Mar 19, 2018 5:47 pm

Sort of a newbie question here. Pardon the noise.

I am in the process of converting my mill (a Sherline CNC) to metric.

Fusion360 offers several modes for its 'scale'. 'Inch' or 'mm'.

Question: Should I then configure my UCCNC for units equivalent to 'mm' ? Or perhaps I should configure it for 'cm' ?

I'm just not sure what Fusion360's POST puts out.

I guess I am confused because I feel that Centimetres are a more 'natural' measure than mm.
They feel more like the 'inches' I am used to.

Never mind, everyone.

I was getting confused by the 'default' alternative units being offered to me by Fusion360. For several months, I only remember seeing 'in' and 'mm' units.

But, in fact, I have found that there are several different metric 'units available. Centimetres being one of them.

I can (and will) configure the 'units' on my mill and Fusion360 to be 'Centimetres'.

I think that the vast majority (99%?) use mm's.

IMHO, you'd better use mm. I never saw any program using other than mm or inch.

Question...
If UCCNC is "unitless" and steps per unit are correct, and CV settings are divided by 10 and a any macros have the motion lengths adjusted, why wont it work?

Nobody said it wouldn't work.
Just not advisable. :lol:

Lots of little things can come back to haunt you.
Like, will Fusion 320 output feedrates in cm/min?
Not that it matters, but you just better have a good handle on everything when you do something in a way that nobody else does.

From the UCCNC side it will work, but only bakers measure in centimeters not machinists. :)

Ah! I did not know that. Thank you for that information.

I will configure my machine for 'mm'.

The nice thing about UCCNC is that I can support multiple profiles. Both 'inch' and 'metric'.
