I have heard it mentioned that the rails are not only larger diameter, but also have increased wall thickness. I haven’t been able to locate the information of differences between Gen 1 and Gen 2. Does anyone know where to find this?
Gen 2= 60mm x rail, 50mm y rails
Gen 1 = 50mm x rail, 50mm or 35mm y rails
X60 rails are 6mm thickness
X50 rails are 6mm thickness

Thanks for the quick response, but I was referring to the actual wall thickness of hollow wall linear rail ( not the overall diameter ). Sorry I should have been more specific.

I thought I saw that somewhere as well but I cannot find it now. It looks pretty close to the same wall thickness from their launch video.

Thanks I do remember seeing these now that you put the pic up here. From what I can gather, 35mm were 5mm wall thickness and 50mm were 6mm wall thickness. I heard at some point the number 7mm for the new gen 2 rails, but wasn’t sure if that was correct, also, if that would be just for the 60mm rails or if thickness has been increased on the 60mm rails as well as the 50mm also.

Any update from @OnefinityCNC on this?
Thanks!
What I am more concerned with is the video showing how much more the gantry or I should say spindle mount moves compared to the Alltmill supposedly. I am wondering if this was ever debunked or was it fix with the new gen2 machines. I have personally never had a problem with it doing anything funky on a carve due to this but then again, I have yet to do any really deep or difficult carves. Yet I do a lot of aluminum in manufacturing my ultra-low profile t track clamps. but I would like to hear more about this.
Yes. Multiple owners reported they don’t see the movement Ryan showed in his video and Onefinity weighed in saying that the machine must have been setup incorrectly because the movement was not normal. The posts were in the original thread.
BTW, although I like CIC stuff and watch his videos, I take any tool advice with a grain of salt if it’s a tool or machine that he’s got a sponsorship deal or an affiliate relationship. Pretty much like all YT creators.

I understand. I hope you will take the advice from me, on my clamps. They really are quite good. and thank you for all the likes on my posts.

The 60mm rails are the same thickness as the 50mm rails, 6mm.

I looked pretty hard at the Altmill, and honestly was the direction I was going to go. I have a very small space and need flexibility and can’t fit a 4x4 machine. There are main things that pushed me to Onefinity over Altmill. 1) Ability to roll and fold the machine with QCW and Folding leg kit. 2) Journeyman when compared to the 2x4 Altmill has more cutting area 49x33 vs 49x24, 3) Z height 7” for the Onefinity and 5.5” max for Altmill. I think when comparing. Altmill to Gen2 on its face the Altmill probably is technically the more rigid machine because of its more traditional design ( total speculation ). The Gen2 has been beefed up in the Z axis, it seems a fair amount compared to Gen1, 60 mm on the X is a lot more cross sectional area than the 50mm. I think Onefinity did a good job of trying to close the gap between Gen2 and Altmill. Functionally in the real world based on my research and experience with other CNC machines, bits, federate, depth of cut, and machining method are going to have more affect on either machine. They are both lightweight hobby machines. I would rather have the functionality of bigger cutting area, more Z height and portability than being able to go 50 inches per minute faster. Honestly what they show the Altmill doing in some of their videos is impressive, but I would never treat my machine like that and they didn’t just throw down a chunk of aluminum and start ripping…I’m sure there was a ton of trial and error before they took the final cut. Camry or Accord….in the end neither is a 911.

Well put. Couldn’t have said it better myself.
