8020 build 3x5

Awesome machine! The motion looks super smooth and fast. If you want to get your Z-axis closer to the gantry to cut down on flex, I now sell a Z-plate that will bolt directly to the carriages spanning your Z-rail. You just need to tap the carriage holes to 3/8-16.

If you're willing to provide a Bill of Materials for your machine, I'm happy to send you a Z plate and low profile bearing (that the Z plate can slide over) for free. I'd like to post the BOM on my site since there's lots of folks asking for good machine plans, and yours is one of the best I've seen. Shoot me an email through the website if you're interested.

Best regards,

Very Nice! Looks like everything is going quick and smooth.

Now comes the sleepless nights, cutting everything you can think of

I'll have to stop over and see it "live" in action!

Good work again.

Looks like it is working pretty good, I am about to convert my system from xylotex to G251's, a 48 volts 7.5 amp, Keling Steppers and a C10 break out board so it was good to actually see one working

Good Stuff....

Sieg,
Did you get the Z-axis plate and bearing I sent yet? I'm interested to see if it works out for you.

Thanks,

Ahren

Very nice machine. When mine grows up he wants to be just like yours lol. Is that the Milwaukee router your using, very quiet . what cutting and rapid speed to you get with the 5 start?I just ordered 8tpi 4start and cant wait to hook them up. Graham

I've been cutting at around 100ipm... I'm pretty sure I have played around with it at 200-300ipm not cutting. I've only cut a few things on it so I haven't pushed it to its limits.

I'll try and post a few pictures the next few days of what I have cut.

The router I am using is a Haitchi m12vc router. Great price for a refurb one here...

Hey sieg

Couple questions for ya...
Did you go with a 3'x5' b/c you bought a 36" and a 72" lead screw so you could cut it for the Z & Y? The reason I ask is b/c that’s exactly what I'm contemplating, lol... how did you compensate for the deflection on the Y? I was going to use a piece of 3030 for the length, but according to the deflection calc ahren said to play with it comes to 0.015in over a 60" span. The 3060 only has a 0.002in over the same span, which is great b/c with the 1/4 in steel its probably nill, but they are awful proud of the 3060 & 1545 in at least a 5' sticks... I've even debated the idea of filling the center cavity of the 3030 with something, maybe extremely thinned cement and vibrate it in, then let it set for a week (like I could leave it alone that long) or a vertical peice of 1" flat steel if it fits tight enough?? I like the concrete idea better though

It looks great btw.. lets get them pictures, I would really like some more of the base…
