4 Years ago I made a choice on the 30x30 MK1. That machine taught me a lot. I then upgraded it to a 48x30 MK1.5 and went down the 1.5kw air-cooled spindle path. The one constant at each step as hobby and side hustle the Longmill and its upgrades have paid for them selves over time. My next step after 4 years of constant learning is I need a full sheet machine. In Australia there are couple of vendors with good solutions for full sheet. However I could not have got to where I am without my experience with the Longmill. Thank You
@@davidgrooms3463 After having 3 routers fail on me I decided I needed greater reliability. Why 1.5kw air-cooled plenty of power for what my Longmill does weight was another issue liquid cooled spindles have more weight to them and honestly my 1.5kw air-cooled spindle has no issues in Australian summers. Some people talk about noise levels and in static running yes they are quieter but by the time you are cutting and running dust extraction there isn't a lot of noise level difference. One solid piece of advice buy a spindle from a vendor that will offer support. Don't buy the cheapest option either.
I think both of these CNCs look like lovely options in their respective segments. But 6:25 this is the cut quality you want to show off in an official video? I mean you're hurting yourselves here, surely some time dialing in cut settings and a good compression bit could've give you some nice video-worthy results.
would love to see you guys put out a 4x4 with atc. that's the magic form factor and feature set for home cnc. auto tool changes are a total game changer and there's a huge opportunity to bring this tech to a lower price point
I LOVE that you quantified the rigidity coefficient! Did you test the rigidity in other directions? (X, Z). Did you test the rigidity at the tool tip, or just on the gantry itself?
Glad you found this helpful! The Y-axis is almost always the weakest direction on any CNC router so we tend to focus on this. Our X-direction rigidity measurement for the AltMill was 1.26N/um and 0.16N/um for the LongMill. The Z-axis tends not be measured since it is typically the most rigid axis and is not subjected to as much cutting force during regular routing. We probe this just below the collet of the spindle/router at the tool shank about 1-2” from the table surface, with the machine in it’s weakest position (centered in the X and Y axes).
No joke have been wanting to get an AltMill for a few weeks now but can not justify the purchase and not have it until April. Hopefully the fulfillment time becomes more reasonable
In the case of foams and very light materials, maximum travel speed will usually be the limiting factor so the AltMill is the winner here. However, this will come down to the type of projects you’re doing, since the speed of the AltMill won’t benefit quite as much if you’re limited by the speed of the toolpath type. For example, engraving is typically a universally slow process across any CNC
@SienciLabs thanks for the response, I was thinking more in the sense of, if the extra rigidity of the AltMill doesn't really add significant benefits in cutting EVA ( think custom foot orthotics) then the Longmill should be fine. Now the Makita router might be the limiting factor in breaking down and maintaining.
Thanks for the kind words! It was the 1.5KW air cooled spindle offered with the AltMill, but the spindle type would not have made any difference since gcode was generated to reasonably match the rigidity and speed capabilities of each machine. A more powerful spindle would’ve theoretically allowed for a faster cut time on the AltMill.

Can you help me understand what the benefits are to running the 1.5kw spindle on the Longmill?

Very honest and informative video.

For those interested, I measured my Shapeoko Pro XL's Y axis rigidity at 0.24 N/μm.
do you do 240v spindles for the uk market thanks Mike
Great video thanks for sharing. Still learning Cnc
Would the only advantage the LongMill has over the AltMill be cost effectiveness?
Exactly the comparison I was after. Thx!

If I want to do production, but only using foam and EVA... Do I need to go with the Alt Mill, is the router the limiting factor?

Do you sell a pneumatic spindle setup so we can use 3rd party tool holders? The Onefinity has that but it's more pricey than I am willing to pay
Excellent comparison at the end however was that the 1.5kw spindle pitted against the Makita or was that a bigger spindle?

@@SienciLabs Does that indicate there is little benefit to running a 1.5kw spindle on the Longmill?
What’s up with the longmill table?
I Want to buy the altmill in January but worried about the tariffs..
Lol, stop being afraid of such silly things. Either buy the machine you want or don't.
Sorotec Compact line 😉
How much did you buy it for?
@@SienciLabs 4000€
Wow that's a lot for such a small machine
