Hi All, cool to find this group on my printer so long after I bought it.
My "2.5up" looks mostly like a standard 2up but it has a second Z-axis motor to lift the opposite end and behind the lateral head axis. I also replaced the controller A fastbot BBP 1s. It has a built in server so it's just an Ethernet device on my network. It has the stone heated bed. I put in mechanical limit switches.
I ran a few tests and found one issue. Because all the movement torque is applied along only one edge of the table, it torques/twists then relaxes. It happens every step of the stepper motor.
So I want to run a shaft extension across to the other side of the platform and add a second belt so both sides are pulled at the same time.
So here is my dilemma... I can't find a new 12 tooth 5mm bore 3mm pitch [I think 3mm is what it uses] timing pulley. Does the original manufacturer still even exist? Or a source for one?
Anyone out there ever change out the pulleys on their machine for a different one and have one from the original they'd like to sell me?
Thanks folks!
Bill

Hi All,
I know most of you aren't logging in here when you do drop by, but I wanted to ask if anyone has been having trouble logging in.
I logged in this evening, and when I was redirected to the forum home page, it didn't show me as logged in. It only showed me logged in after I refreshed the page manually.
Anyone else seeing this?
Thanks,
Stan

Hi All,
I haven't tracked down the issue yet, but there is some evidence that there is a problem with some of the registration emails.
Everyone who has registered that I am aware of has had their account activated. If any recently registered folks can't log in to the forum, please let me know the details of the problem at fabric8rsite@gmail.com.
Thanks!

Guilloche! |

Google it for more details. It's the technique used to make those unique lines on many currencies, fancy watch faces, and a lot of other places, although those are a lot more sophisticated then my efforts. These are my first attempts at guilloche, and one of the first projects on the cheap 3018 (worth more than it costs if you understand it's limitations). No claim at great art, or even great guilloche, these have more detail the the size and material/router support, a diamond drag bit would have been great but they're too expensive for a $200 machine. I'm an engineer, not an artist, too.
These are from a 12x24" copper anodized aluminum sheet I picked up at Home Depot, and are 50mm square. Feed rates, depth of cut, and level of detail need more work, they're too detailed for the size of the work area. They were cut with a 20 degree engraving V bit, a 10 pack came with the router and so far I've only broken one (by hitting abort and having Candle jam it into the spoilboard and then try to move it). Feed rate started at around 500mm/minute but I played with the speed override quite a bit, both up and down. The bit left a burr around the engraving, not sure if that enhances the effect or worsens it. Need a lot more practice, fortunately 12x24 yields a lot of 50mm test pieces.
