Thank you so much for a very clear video. There is a paucity of videos about the Carvera , this will go a long way on bringing me up to speed. My machine has been shipped , and trying to learn as much as possible about its operation and the associated software. If life allows please do keep posting.
This video was so informative! Thanks for taking your time to go that in depth. I'm not a trained machinist but I do have an interest in engineering and have several 3D printers, and some knowledge of Fusion 360. This video made me really confident in going forward towards investing in Makera's upcomming Carvera Air machine and trying out CNC for the first time. Subscribed for more content!
Excellent, informative video. In particular, i didn't realize my Carvera could cut metals that aggressively. And the little tweeks to the tool library and profile will come in handy. Thanks!
Tips for beginners. For the spoil boards, check the material thickness, looks like the new spoilboards are closer to 2.9 mm in thickness and 239 x 199 mm. If set at the 200 wide, the probe may miss the edge completely and when probing, the mill will over compensate and give you extra deep bores on one side. It might also be worthwhile to offset the construction rectangle by the anchor brackets width so that you get more useable area from the spoilboard.
First video I’ve seen doing real cuts of any significance. It appeared to do surprisingly well. I was afraid this thing would have to nibble away for hours to make those kinds of pockets.
This is difficult for a beginner so really practice makes perfect this reminds me of when I started cad class for building I guess steps become like breathing the more you practice but it’s a lot to keep up with at first
@@techydiyawesome. I'd love to have a mini pcb mill I have 2 new lasers I've never used and 3 bigger cnc machines I keep meaning to assemble. They can shrink it so much if they made a pcb centric one. It's funny man, I'm disabled and on a pension and donate half my disposable income and I see ding bats like great Scott get one and poor shame the audience then never use it. I'm surprised people don't notice how often that dude craps on his viewers. I don't give to receive but it burns me when companies give things to people who are just looking for a pay cheque. Pcbway prices are so high because they sponsor everyone as means of the ccp gaining softpower and jlpcb are 8 dollars one time and 200 the next and I stay within the sizes haha.
Awesome video mate! Just started in the world of cnc with my carvera have a lot to learn! Is there any reason why you would use one calculator over the other?
Yes absolutely, the machines, resources, support and community are all excellent. The example projects really help get you going. I have tested quite a few machines over the years and the Carvera is easily my favourite.
Excellent video I tried cutting AU4G with the exact same settings but my 3.175mm carvera example tool broke after a while, I didn't use any form of lubricant could it be the reason ?
Hard to tell without seeing what happened, that is one reason to video it, you can go back and figure out what went wrong. The HSMAdviser, material reference (MORE) gives 7075-T6 as a cross reference for AU4G. That results in a lower optimum load (cut width/depth) and feedrate than for 6061-T6. I would usually start with conservative settings. and then increase if necessary.
What is approx the "deepest" pocket I can cut into aluminium - the longest milling tool which could be used to deliver still a "clean" cut without having to much vibrations?
@@techydiy this is clear that it have to be done in steps, but what is the "longest" tool which could be praticaly used without having to much vibrations, assuming that I do not need high speed, I just want to make a " deep" pocket
Uhh... that spindle is underpowered for the cuts you are taking. It should not be slowing down as the end mill enters the cut. For the price they are asking, it really ought to come with at least a 500W spindle as a base configuration, and a 750 or 1KW available as an option (possibly with an additional bracing kit to improve the frame rigidity to handle the increased cutting forces). I really don't like that you can't have both 1/8 and 1/4 end mills in the ATC at the same time due to them being directly clamped by a collet in the spindle - a toolholder system like most other ATC systems use would have been a better design choice. And I really would have preferred to see proper linear rails under the bed instead of unsupported shafts.
I was showing the top end of what the machine can do and Makera do recommend less aggressive cuts at a slower spindle speed. The spindle has closed loop control and it varies output based on the load, so what I think you can hear is the spindle adjusting to the load. If you look at the spindle power requirements in the feed and speed calculators then they do not come close to 200w. The machine is designed for general prototyping, rather than specifically machining metal. Yes, not being able to use different shaft sizes together in the tool holder is a valid concern. There are ways around this limitation and there are of course advantages and disadvantages to all tool holder systems, so ultimately you choose what works for what you are trying to achieve. They did have fully supported linear rails on the prototype machines and they were less rigid and the results less precise than with the current linear rods, so I have no concerns about this at all. Thanks for the comment.
I think there is value in seeing the limit of the machine's operation. To see how it operates when it is pushed. As far as the limitations on the machine. It is what it is. Some of the design decisions are a bit light. The unsupported shafts are significant in diameter and are adequate for a machine with low spindle power. It seems to be well designed for a low power machine. Is it the right machine for me? No, but it meets the needs for some people.
