Hey guys,

I know this thread hasn't been touched in a while but just thought I'd pop in and say this machine is still going strong!

I finally have my home shop all situated - we put in a pole...

10 tpi, 1/2" acme threaded rod, single start, running dumpster leadnuts, being turned by 425 oz./in. Keling stepper motors, driven by a 40v Keling controller package.

We are cutting with a 1/4",...

I stopped by Spencer's again today to continue playing with the CNC machine.

We currently are having software issues on the old laptop we are using as a controller. However, I have a computer I am...

hey guys,

To be honest spencer and I haven't worked on the machine in a while. A month or two ago i ponied up and bought this keling driver:

It came...

Thanks, HayTay. Well, our actual tech class ended last Friday, however, the machine isn't "due" for any grade, so at this point we are just working on it at my shop, and whenever its done its done. ...

Everything is starting to come together for our CNC. Last night Spencer slept over and we glued the second skin onto the X axis torsion box. This morning after Spencer left (he has a big school...

Wow! Thanks, everyone! Reflow - you fixed on problem perfectly! I checked in diagnostics and found the pulse frequency to be jumping by tens of thousands, it was awful. I changed the computer to the...

Thanks Bob,

After reading your thread I tried to find how to turn off idle current reduction, but found that our board doesn't have a 4th jumper pin. We have the 4AUPC rev2 board, and Spencer and...

Thanks everyone,

Spencer and I played with the motors briefly. I believe we have the jumpers set to half stepping mode, with a jumper on J1, but not on J2 or J3. We changed the steps per inch...

Thanks, guys!

Well, we have had problems in Mach for a long while now. We are using a hobbycnc board with 300 oz./in. Keling steppers connected to a 24v power supply, I believe it pulls 8 amps...

Thanks, bp! I am currently at Spencer's house and we are just about to go and start priming all of the pieces. Once they are all primed and ready to rock I have some blue paint we might use for the...

Thanks for the continued support, everyone! Today in class we made a lot of progress, and we're at the point where the machine is really starting to come together, and finally our dry fits actually...

Thanks for the great advice, Dave! Today was indeed an awesome day, it was just great to be able to visit Joe, see a solidly built Joe in action, and receive some real life advice from a truly nice...

Parts have been ordered!!

We're getting there, rdh! Spencer and I return to school tomorrow, and I do believe we can finish all of or at least the bulk of the work for this machine before the month is over.

Hey Spencer,

Conduit will work but it needs to be polished first, and we'll have to make sure it isn't all banged up etc.

Sorry this has been going a bit slowly lately guys, I have a crazy...

Beautiful! Thanks for that link, those are great prices.

Hey guys,

Yes, our controller is assembled correctly and even hooked up to my computer as we speak. The tuning issues have been mostly worked out and all three of our 300 oz./in. Keling steppers...

Thanks guys. A ton of progress was made today on the gantry parts, but I assume Spencer will be on here soon with pictures...

Wow, Joe! Thats incredibly kind of you!! Spencer and I both nearly fainted when we saw your last post! Everyone here at CNC zone has been so supportive and generous, and we truly appreciate...

Thanks for all the positive support, everyone! As Spencer has all ready covered, more progress was made today on the X axis. Here is a video taken on tuesday showing the cutting action on some...

When generating the toolpaths, couldn't you simply set the drilling method to "peck" and have it take multiple passes by pecking down, clearing material, pecking again, clearing, etc.?

I can answer those questions, Spencer. The difference between the center-most cutout is 1/8" less than the other pockets, meaning our machine will theoretically have 1/8" less travel then before.
...

Thanks Kent,

If everyone didn't all ready know, I'm Tyler, Spencer's partner in crime in this crazy hobby of building CNC machines.

Believe it or not, its been over a year since we first...

Our bit is an upspiral bit.

Ok. Basically, you're gonna wanna turn the machine on, hit the down key a lot so it boots into Linux, then open up the CNC program. Then, you're basically gonna wanna router, and uh, slam it into the...

I can't help you with the cutting area, but Joe does indeed sell full kits, he will cut all the parts for you and ship them right to your door for a fee, however, if you are in the UK I'm not sure if...

Thanks a ton, guys! Those links both helped a ton.

Haha, you are correct, bp! There are plenty of lurkers like me on this great forum...

Hey guys,

This is mostly directed at Joe, but if anyone else knows please feel free to chip in. Anyways, I am starting to cut out parts for the Joe hopefully this week, and when I went to download...
