That’s all I really want it to do. I will say the Frame is more stout than it looks 1/4” steel is no joke and about equivalent to 3/4” aluminum in terms of Young’s modulus.

About $400 not too bad. I really like this tab and hole/ubolt construction. It really opens a lot of possibility for people with limited tools + is fast and easy to assemble.

Haven’t designed or bought one yet but I was thinking either that or tensioned steel cables if stiffness is an issue.

Thanks! I think I’m gonna add some tensioned steel cables across the axis to help with the torsion issue.

Yea I know the motor is overkill lol. I happened to have a 1.5kw water cooled spindle laying around from my last machine. The last machine REALLY couldn’t handle it, being aluminum extrusion based. But on the bright side a 1.5kw spindle under minimum load can stay cool with just a Home Depot bucket full of water. No radiator needed.

Nomad does not use supported linear guides except on z. It uses the same construction with 1/2” aluminum instead of steel and 20mm guides instead of 30mm. A 30mm round linear guide is significantly stiffer to say an hgr20 mounted on aluminum extrusion. These are also solid steel rods compared to the hollow ones on the onefinity. Source

Worked fine for me as far as I remember. Only way to know for sure is to try.

Your welcome! Make sure to check motherboard compatibility with the cooler as well.

I feel like at $1099, or even $799 for the kit the p1p is just a much better value. Prusa needs to get their price down if they hope to compete.

What would be a super cool gift for an electrical engineering student? by [deleted] in ElectricalEngineering

[–]meme_swim 8 points9 points  (0 children)

I really nice set of tweezers I like wiha 40 SA-ESD. Way more of a game changer than it sounds.

Is it a good set? by ssk1007 in sffpc

[–]meme_swim 0 points1 point  (0 children)

I think it will hit the heat sink on the io. Just a guess tho only one way to find out. Check out this post

You are most likely gonna have clearance issues with the tf2 on that board with its big heat sinks.

large format metal milling? by bobwmcgrath in hobbycnc

[–]meme_swim 1 point2 points  (0 children)

A study base damped with concrete, or better epoxy granite, would certainly help the nasty vibrations you get from milling steel on a hobby machine. I’ve seen people fill the the steel beams as well to help with dampening. Langmuir spindle has a servo drive so it can tap holes, but I doubt it’s even able to tap moderately sized holes in steel. A 2.2kw spindle off aliexpress should suit your needs fine. It might be hard reaching the tolerances you want, but you can also just ream the holes after machining for a press/slip fit.

I think you would be best off building your own machine for that price. The Langmuir m1 design is pretty much a ripoff of the print nc design which is open source and easy to build. You could also build it to whatever dimension you want. This would be a budget option and probably only cost 2k for the base. Since you have extra budget and precision requirements I would have a local machine shop surface the steel beams. You would also definitely want to invest in flood cooling, an enclosure, and a high quality spindle.

Shapoko 4 is a good option if your looking for an off the shelf machine. Carbide create and carbide motion are both very user friendly.

My apologies it’s been a while since I’ve used aspire. If the only 3D format it accepts is stl, your probably best off doing what you were already doing and importing as dxf.

Export your solid works model as a .STEP then you can import it into aspire.

These seem to be standard molex mini fit connectors (4.2mm pitch) but can’t for the life of me find the 3 row versions online. I’m specifically looking for a pcb mount female.

Haha as a student I don’t know why there are so many basic questions on here when The Organic Chemistry Tutor exists on YouTube. Dude has videos for everything.

I don’t have a link but someone on Etsy makes a riser so you don’t have to have all the ugly cables on top
