This is my first project with my 3d printing. Still not completely finished, but it’s working. I have some wire management left to do, and some zip ties to snip. Also planning to mount RAMBo board on side, and power supply under table. Loving this machine, tons of fun.
I did get unlucky on a few things while building it…
I originally bought, and cut to length, sched 30 “scaffolding” steel pipe. Heavy stuff, that stuff was tough to cut and cost a bit more than I was expecting. Only to find out weeks later when my printer arrived, when I started looking to print the parts, that none matched the O.D. of the pipes I bought and cut. Dang it, that’s too bad, these are some heavy duty stuff, and smooth too.
Then the graphic display. The ribbon cables have a notch that only allow hookup one way… backwards. The thing only blinked at me at first. I had to take a rotary tool and shave off the notch on the cable to shove it in backwards to get the display working. What a pain.
Then I found that the few bucks I saved on NEMA 17 steppers… I should have payed more attention as I got .4 amp motors and ended up having to go back and replace them all with 2A steppers. Now to find a use for these spare stepper motors, maybe an eggbot or desktop lasaer etch.
Now I’m waiting to replace the 24v power supply I bought for it with 12v one (using old PC power supply for now). I should have known the extra heat dissipation (voltage drop at drivers * current) would be too much. What was I thinking, I don’t have a 3d print bed to heat here…
This one is almost comical… I found your plans for “Easy Conduit Clamps” the day after building the table for it. Man, maybe I could’ve used those spare scaffolding pipes for that.
Oye, you have had a bit of a rocky start. You stuck with it though, without blaming anyone, you will fit in well to the crew here! I think we all try to do things a bit different to either share our success stories…or wait a while to bashfully admit the non-successes.
You wouldn’t believe how many emails I get telling me I didn’t have all the information on every page and it is my fault for their poor part choice.
If I could go back and tell myself one thing to save time and money… it’d be that not all NEMA 17 steppers are the same. I’ll probably find a use for these some day soon, but the time spent wiring them up in hot garage… geez. My own fault for not doing enough research before making the purchase. When buying the replacements I just used the Amazon link from the parts page (handy, thanks!). At least I had compiled my own firmware with the correct digipot settings for .4 amp so the smoke stayed inside them, and I could enjoy the machine a little while waiting for 2 amp the replacements
One thing I found when printing the parts for dual endstops: On the parts page the link for the optional Dual RollerPlate is on the line with RollerMount. It confused me a little bit at first, until I realized that link should probably be on the line below with RollerPlate.
My first question on this machine as a new user… Does the weight of the hanging Z wires (off the table) keep them off the work surface and out of the path of the milling bits? I’ve only been using small work area with a pen & paper, so I’m trying to figure if I need more cable management for Z axis before putting in DeWalt router…
You should not let there weight pull on the Z axis. Have a look at the tape measure trick. I have it linked in this post. It does not need to be in a sleeve, tape or cable ties work just as well.
