Fusion 360 w/ MPCNC Feeds and Speeds

Mostly Printed CNC - MPCNC Advice
1

So please forgive my ignorance, I am sure this has been talked about before, but either I cant find it, or I am not using the right lingo.

So I am following the recomendations outlined by Ryan as per “Milling Basics - V1 Engineering Documentation”

and well, let me re-iterate, I am TRYING TOO :slight_smile:

I have used these numbers in EstleCAM, and Aspire with much success, so it made sense to me, that I should just replicate them in Fusion 360 and it should just work.

hehe, Well you dont know, what you dont know, till you try it!!

I think I have my Tool setup for using a Feed rate of 8mm per/s but well I would argue that the 134 hour cutting might not be right.

So, my question is, if I want to have a feed rate of 8mm perr second, what should my actual tool look like, or is there another setting i am not setting properly?

Those feeds are millimeters per minute, so you should use 480mm/m.

No worries, happens all the time to me. We also see it here with “my machine isn’t working! It doesn’t move when I hit go!” Actually it is moving, you just can’t see it…

if it wasnt for the Info screen, i would have made that call.
i could see it increment, but I could also see the paint drying as well.
just couldnt figure out why

ok, So I have a follow up question, hopefully you can answer, or someone can.

While setting up my Fusion 360, I followed this video for the General Idea on what to do.

“https://www.youtube.com/watch?v=UcBULdrHPNI”

Some of what he is doing makes perfect sense, and only now when I am looking at my Gcode, I realize there is stuff he is talking about in the video, he is turning off. but is not available to me in the post procesor.

At 5:04 he talks about a setting to GOTO 0 at the end. but in the Post Processor I have, that feature isnt there.

At 6:31 he talks about disabling the reset on Start (g92) also something I dont have in my Post Processor.

However, I just noticed in my Gcode, I have

;Fusion 360 CAM 2.0.7463
;Posts processor: MPCNC_Mill_Laser.cps
;Gcode generated: Saturday, February 29, 2020 11:13:00 PM GMT

Which for How I am doing stuff, this is screwing me up.

so, I can just delete the line, but I am also at a point now where I am wondering if maybe I am using the wrong Post processor or do I need to message it?

have a suggestion? toughts?

the one I found when searching was" Posts processor: MPCNC_Mill_Laser.cps

ok, Well I think I found the problem at least why I wasnt working from the right Post processor.

when I searched for it, I was able to download a different version of it.

I think I have the one from GitHub now.
