Thanks Lars. I was also confused about heights and was working from the top down. Your explanation is much better.
As always I make significant progress with Fusion 360 after watching your lessons. They are an excellent resource for learning. Thank you so much for them.
That is awesome to hear Denis Chambers .Thank you for watching the videos and comment!
Best,
Lars
Great, thx
Most definitely the best, most comprehensive explanation of the heights tabs, I've been praying for this for a while!
That is awesome to hear Tbev .Thank you for watching the videos
Great video Lars, I was really confused about this but now it makes sense. Thank you
Thanks for lots of information and tips. Much needed for hobbyists
You are so very welcome :-)
Thanks Lars, another great video nice trick with heights starting from the bottom, starting to make sense of it al.l
Congratulations on the new baby!
Thank you Dave Anderson
This is great, thank you!
Great video! I was confused about this until I saw your video. We just got an 8 tool ATC spindle and.... well, I buzzed through some wood at the wrong angle until you made it clear what heights were. Thank you!
Glad it helped! Thank you for watching
Yes that was helpful. Thank you.
hey lars, great vid, it took my a while to figure these out...i did not hear mention of the following in the heights tab for the drilling operation..
the feed height setting controls what the height the tool will rapid to...then once it reaches that feed height setting, it continues down to the hole but at the feed rate setting (plunge rate) that is set in feeds and feeds tab .
so sometimes if i have a really small drill bit that requires a feedrate of say 3 ipm, with a chip breaking partial or full retract cycle it can take a really long time for it to get down to the hole if my part is kinda tall.. so i set the feed height lower and closer to the hole top (+1mm above hole top)and make sure my retract height is high enough for the tool tip to clear any obstacles that may be hit when the tool tip is moving from hole to hole.

Thanks mate!! love watching your videos!
Awesome!!
it,s best video eve i have seen explained cam good so fare and direct for every one to make production seriously .
That is awesome to hear BIRIMA BURMA .Thank you for watching the videos
Just starting w CAM so this was clarifying as!!
I know I'm nit picking, but I'm just curious why you choose the top height as the stock top (which isn't there anymore since it's been faced off) and not the model top? Just curious... This means your tool would be machining in 1mm of emptiness...
I need to be able to click "Like" every thirty seconds. Thanks heaps.
Thanks Lars!
thks Lars, it was reaaally helpfull!
That is awesome to hear Gligorijevic Polo .Thank you for watching the videos
So I'm struggling with a problem that I can't seem to figure out. For years now I've set my retract height to .01" to reduce the time the machine takes to rapid up. Especially in tight 3d adaptive operations where the tool rapids up in z many many times. The problem is no matter what I program the retract height to be, it's always way higher than I programmed. Not only that, but it never changes the retract height at all unless I make it some absurd height. I've checked my setup model, and have tried every option there is in the heights tab. Please help!
Thank you very much!
You are so very welcome :-) Thank you for watching!
Hello Lars. When I post a facing operation, the software is automatically removing .135 (it is subtracting my model finish dimension from the stock dimension, then dividing it by 2) How to i tell the software to only remove .020 on the facing operation? Thank's so much! dave.
im having the same trouble as Jeremy:
"I'm still confused. when i press go, it wants to run straight across the top of my model to the starting point instead of retracting then moving. but during the operation it retracts like it should."
I have notice 2d contour and 2d pocket being for same stuff by 2 different people, what is the deal with why one uses one and why another uses the other?
awesome...
Lars, you got me over the hump.
I was confused trying to understand what the software was trying to tell me with the color of the height clearance planes.
If the table settings color matched their respective planes I probably would have figured it out.
Thanks
Hi Peter Schmelcher Thank you for watching! Glad you found this helpful!
Best,
Lars
Maybe one day they'll invert that heights tab list, as Lars suggests🤣
thank you
You are so very welcome :-) Thank you for watching!
Big Thumbs UP
Thank you!
Ahaaa.. 3d means its the entire feature its dealing with, not a 2d contour line.. New learnings! Thx Lars.
You are so very welcome :-) Thank you for watching!
lars,I really do get a lot out of your videos.I would like to see a cad and cam together video if possible....Thanks
Hi great videos followed and placed a basic shape on the top plane z axis up y point to rear and x left to right as you look at the screen , my object is on the top plane when I select the bottom perimeter and add tabs the point direct upwards instead of out to the side ?
Sorry this should have posted against your tabs video?
30:30 on my computer is not right click anymore. It can be accessed by left click the thre dots next to the entry.
Hi Lars, First Thank You for all the great Videos. I use you, Titans of CNC, Lets Machine and NYC CNC for my CAD and or CAM training, you all are awesome. One trick I picked up on with Heights was for facing, 2D contouring and Pockets was to set all the tabs to Model Top and use dimensions for the positions. After doing that a bit it was easier, for me anyway, to get a better handle on what each does in a given operation. Now I may vary it a little for different things, but it removed or simplified it for me starting out. What are your thoughts on that, can you see any disadvantages to doing it that way?
Thanks again, Mark
Hi Browningmotorsports Thank you for watching!
Titan and John Saunders are both on my hero wall :-)
No, I think that is a totally legit way to do it. Thinking about it, if I was programming a part that also had a 2D print, I might do it your way. Just because the print dimensions would overrule anything else :-)
Best,
Lars
hpw did you creat the cylinder shape in the model
27.03 omg looks like my makro lol.1 parameter for depth it cut pocket that depth using tool radius and leave flat bottom if its flat mill. even leave more if you select full depth it calculate how deep it can go your tool. same for ball nose same makro with nose radius and do finish. cutting cutting.. finish
Now I (think) that I understand. Thnaks!
Hi Laurence Schenk Thank you for watching!
You let me know if any confusion should show up :-)
Have an awesome day!
BEst,
Lars
how do you set DOC on profile milling? if im profiling out of a billet, I need an infeed (Depth Of Cut ) rather than just plunging to max depth through solid material. I don't think my end mill OR VMC would like that!
Hi crozwayne Thank you for watching!
There is an option for selection in the depth of cut so you can select a vertex on the screen or you can use the offset field to enter a depth
Lars A good video on a point of confusion. My question is: why after the facing operation, wouldn't using 'Model Top' instead of 'Stock top' on the subsequent operations be a more logical reference? I never have need to 'face' a part.
Hi Jim Mac Thank you for watching!
I you stock is set to the same height as the model, or if you have done the facing, they are the same. But, most CAM people are very caution minded, so I think most people like the safety of stock top.
Great question.
Hope you have an awesome day!
And where is the tool change position height? I have a program that stops to close to the part and don't have enough room to remove the tool.
Shouldnt everything be from "stock top" because that is where you zero the bit height?
im trying to start my toolpath with the spindle directly centered over the model.. I tried the stock box point selection , and model box point selection with no luck.. thanks
Hi Rob M Thank you for watching!
I am not sure what is going on there. I would recommend you go here for better help:

Best,
Lars
as it turned out , I simply need to zero AFTER I load the g code in mach 3.. not before.. So from fusion to mach 3 to the 6040 cnc , there is some confusion , but its all worked seamlessly since I started zeroing the machine after loading gcode.
Thank you once again for explaining the heights tab! Grate work. But i got small error/warning -> "Warning: Lifting retract plane to safe plane." what safe plane is in addition to retract plane?
Hi Piotr Szmidt Thank you for watching!
Check that you don't have something like your lead in/out on the linking tab going higher than your retract plane.
I think that was not the case. Unfortunetly through the searching of the problem I changed things so many times that I've lost control of what i finaly was changing. My assumption was that the problem was with the height of the BOTTOM setup - just some miss-click and that give me error. But thanks again :)
Can u do a session on a box for a fixed blade knife. I want to cnc a box out of wood to put a fixed blade knife into for a gift.
Hi Lars. I recently made my own CNC but i am struggling with one part. Which height will tell me the starting (home position) height of my cutting bit. If my feed height is 5mm and clearance along with retract is 10mm for 2D contour process then how high should i keep my bit and start my gcode?
Hi Prashant Kumar Thank you for watching!
I am sorry if the video is not clear. Not sure I can do a better job than I try to do in the video. But, as you start the program, the software will read the clearance height and go there.
Best,
Lars
same issue , my gcode starts milling the air 7mm above the stock.. not sure where to zero the machine
@@airgunningyup and Prashant Kumar, When you enter CAM in F360 the first thing you do is set the stock origin to the top of the stock. When you fire up your CNC you need to home it to the top of your stock; to do this you need a Z-probe.
Wish if you make a similar video on passes as well
Hi Sunil Saxena Thank you for watching!
That could be done :-)
It was very Helpful
Thanks Lars you do great vids , BUUUUUUT fusions height tabs are the rube goldberg of the machining world 99% of machinist's program from top of part as the ABS reference . I waste so much F#@$ing time with this tab I have to change to modal top every single time every tool, Oh and no user defaults ya for the values but not the ref point I HATE height tabs.
well yeah all that sheet is great but i tried diffrent methods and my Z axis cant freaking get it...
as soon i hit cycle start in mach3 the Z axis its going way far upwards than the heights settings iv put in there,
It have to do with this line here (g28 g 91 z0) how the fuck do i set this up T_T
when i was running some tests on halftoner there was an option SafeZ that i could just set the distance that the spindle will keep when going to another task and it was doing that... unlike fusion faqin rocket sience
Are you milling with a drill? That could leave surprising results 😂 I wouldn’t recommend that.
can u add the models to linked description
Not sure I understand exactly what you mean
Cant find the View Toolpath. Where oh where has my View Toolpath gone?
Hi Charles Haerle Thank you for watching!
Right click the operation and it should be near the bottom
Taking a break on this one. I don’t do CAM. All the best.
Understandable :-)
16:34 OMG ofc it is. origin is there.model is there.its faced. IT SHOULD KNOW THAT!!! that drop down is pointless.and actually you allready cut it it should be model top or top of feature you cut.
lol @ cheesecake factory menu
14:44 exactly it go thru if tell. it SHOULD NOT DO IT ITS CAM AND SMART model is there . dont cut more !!!!!!. if i would make that there would not so many options.
Stock top is only relevant in the first step, then it’s gone. Stick with model top.
not work for me invalid path this fusion is a opinion not math!
Please speed up and stop shaking the cursor.
Utter nonsense. More and more Fusion becomes the tool for Prusa owners and nothing more
