Easily Master CNC Chip Load, Feed Rate, Stepover & Stepdown!

[@michaellevine6019]

Your ability to explain things never ceases to amaze me. Thanks for this tutorial.....

[@Timberfalls]

Thank you, I appreciate the kind words!

Thank you for amazing in depth explanation !

[@Timberfalls]

@rajendergurung7867 I am glad this helped and I appreciate the feedback. These comments help.

I love your teaching style. I would love to see a video explaining roughing passes and finishing passes. I have a lot of unnecessary wasted carving time on my finishing pass. Do I change the start depth?

[@Timberfalls]

@jimhensley4210 the finish pass should only leave what the roughing pass does not get. If it carves air uncheck the z passes settings or check safe z settings

[@jimhensley4210]

@@Timberfalls I have safe Z settings at .25”. Do I drop it lower to accommodate the roughing pass? How far?

[@Timberfalls]

@@jimhensley4210 safe z is how far the router retracts in between moves. If you do not have any thing that the bit needs to clear on top of the wood like clamps this can be set really low like .05-.1 and it will speed things up.

This is really good stuff. I have always had issues with down cuts as I can not stop them from screaming. Very aggravating. You should do a video on what bits are best used for what cuts. Like is a straight bit better for roughing.

[@Timberfalls]

Great suggestion. I have not made a video about that so I will add it to my list of things to do. I appreciate the support.

[@jdholzen]

Thank you so much for this. I had to laugh at the end because I did exactly that. Super slow in when I got the machine a few weeks ago, and then learned about Speeds and Feeds and now, I'm certain I'm going too fast. All the while thinking I was finding the limits on my little Bob's CNC I've got here. This video was super informative, so thanks again!

[@Timberfalls]

I am glad this one helped and I think once you get this dialed in your machine will cut better than ever. Thanks for the positive comments and the support this feedback really helps.

SO MUCH GOOD INFORMATION IN THIS VIDEO!! Great job Jason!!

[@Timberfalls]

Thanks man I appreciate it.

[@kkofodh]

even tho im just a few mins into the video so far. i feel i must comment for the benifit of other viewers that might wanna dable in CNC - so far everything said is Correct, AND is the exact same for metal cutting CNCs

[@Timberfalls]

Thx for the supper positive comments. I actually got started in a metal machine shop machining with traditional machines before the woodworking and is were I picked up a lot of this stuff.

[@OpmacGamingLounge]

Great stuff. Suggestions on best bit to use when cutting birch plywood and to reduce tear out on the side wall of the plywood. Very tricky. I have had best success with downcut overall.

[@Timberfalls]

Downcut endmill but maybe try traditional direction instead of climb. I also recommend slightly higher rpms when doing birch plywood just be careful it does not start screaming high pitch sounds which would mean your feed rate is too slow.

[@OpmacGamingLounge]

@@Timberfalls Thank you. I will try this!

[@customwalldisplay]

Great video!! You have taught me so much with all your videos. I use this software and use Onefinity cnc. Keep up the great info

[@Timberfalls]

Thank you for the positive feedback and comments here. They help.

[@gglovato]

I've noticed the marks and fluffyness with compression bits where the edges encounter in the middle , that's why we stopped using them even when everyone recommends them for cutting

[@Timberfalls]

Yes that is the downside of compression bits. Have you tried using an O flute? There are some kinds of composite materials that cut better with an O-flute because the flutes are larger than the chips created.

[@gglovato]

@@Timberfalls The problem with O flute it's the they're either upcut or downcut and very steep, and i can't use either as i need perfect finish on both sides that's why we went to 3 flute straight

[@LuxeWoodcraft]

Great video, thank you. Is chipload still important when you are using a dust boot and dust extraction? I figured most of the chips are being sucked up by the dust collector therefore reducing heat in the material and the bit. Is that correct? Cheers 👍

[@Timberfalls]

No chip load from the bits settings is the main reason for reducing heat and the dust extraction has no impact other than keeping chips from building up in front of the cuter and reducing chip load efficiency.

[@TradeSkillersAnonymous]

Really good info, JR @ trade skillers anonymous (subbed based on quality of info and presentation) Well done!

[@Timberfalls]

I appreciate the sub and the kind words. I watch and subbed to your channel too.
