A few pics swell, got the bigger bearings onby Qdeathstar - CoreXY Machines
Got her running. A bit slow and loud with the stepper whine, but its moving Got the bigger bearings for the idlers installed and remade the motor mount to allow all the belts to be paralell as well.... so its looking up Tomorrow i am going to try to see if I can attach a pen to the machine and do some speed tests.by Qdeathstar - CoreXY Machines
I am starting to get the xy plane of my moving via some steppers. I have got it to move, however i am running into some annoying software problems. I am using the latest marlin release on a rambo board... (will be getting a duet for the final) Right now i don't have any endstops (except ones to mechanically prevent the rails from decoupling) so i moved the carriage to one corner of my machineby Qdeathstar - CoreXY Machines
The thing about that board is that it uses crappy steppers and if you want to ever expand you'll toss that one in the scrap bin.by Qdeathstar - CoreXY Machines
Nicely done. I wish you had of taken picturesby Qdeathstar - Look what I made!
Mr Numbers, You are saying that for a given result, the coreXY costs less that an HBot. Doesn't that make the coreXY objectively better?by Qdeathstar - CoreXY Machines
Thanks! He is asking how many slots i need. I would guess i only need one in the middle. But, did you also have him flat the shaft at the ends for the set screw or, is that something i can do myself with a file? Not sure how hard the metal is...by Qdeathstar - CoreXY Machines
Looks nice. Lots of machining. . Why did you decide to go with shafts instead of rails?by Qdeathstar - CoreXY Machines
I see you have used the Rhyno to control the belts. I was wondering what size rod did you use? I think i read 8mm. I cant seem to find a datasheet for the rhyno drive. Also, it looks like it uses a pin to lock the rod in place in the picture, but it like you have some sort of coupler. How did you attach the rod to the gear? Finally, did you use the stepper motor that comes with the Ryhno drive oby Qdeathstar - CoreXY Machines
ah, i see now. I have the belt entering from the front and the tell sticking out the back (closer to the aluminum plate in your picture)by Qdeathstar - CoreXY Machines
I was able to finish a version of the effector mount. I haven't fully decided on my hotend it yet so there is definitely going to be changes.... im thinking about either dual e3dV6 or i've already a cyclops i modified to have water cooling. I want to do a direct drive (no bowden) system, however. I have might have some Nimble extruders for the cyclops, and if they get here and work that might beby Qdeathstar - CoreXY Machines
Looks very slick! Its so shiny.by Qdeathstar - CoreXY Machines
I feel like most people move the bed for a reason. XY is constantly moving, moving in it in another axis might add too many degrees of freedom. I can't imagine a benefit.by Qdeathstar - CoreXY Machines
Here are a few I took yesterday. I need to adjust/redesign the xy interface because the linear rail sticks out in front of the bearings. My plan is to add a second piece of 2020 extrusions between the bearing block and the x rail. I'm sort of impressed with this. I can move the printed piece side to side to make adjustments that ensure the belts are parallel, then I can slide it back to tenby Qdeathstar - CoreXY Machines
perhaps the triangle is misaligned in your slicing software.by Qdeathstar - CoreXY Machines
Ok, thanks guysby Qdeathstar - CoreXY Machines
I am building a printer similar to Digital Dentist's build and will use many of his ideas. I wil take some close up pictures soon, as i have made some changes (READ: Sacrifices) due to lack of a milling machine. Anyway, here is a video of a potential problem: In the video, I am holding one side of the y grantry still, but as you can see, i am still able to move the other side a little bit.by Qdeathstar - CoreXY Machines
You should slow your printer way down to 1/3rd speed and see if the artificial still shows up. If it does, it's most likely an issue with the z axis. If it doesn't it's probably the xy plane skipping steps.by Qdeathstar - CoreXY Machines
Maybe your x-y movement is off in one direction causing the belts to slip in one direction...by Qdeathstar - CoreXY Machines
Are there any example of built printers that use rotary encoders. I thought there were some stepper motors with rotary encoders built in? Or, actually, are stepper motors sort of rotary encoders themselves, since they move in discrete steps and if you turn them they will generate voltage on alternating pins?by Qdeathstar - CoreXY Machines
I found out my linear rails have retainers on them by accident! Boy was happy. And Derped.by Qdeathstar - CoreXY Machines
hi. i am moving forward with my build. My question is does the belt from the stepper to the first pulley need to,be parallel or is just between pullies that everything needs to be parallel?by Qdeathstar - CoreXY Machines
looks really good. I limped the way the 2 layer polycarbonate refracts the leds into a starlike pattern If you want to go crazy hook up several of these bad boys and get blinded by science, litterally.by Qdeathstar - CoreXY Machines
Aren't uv lights hard to see by definition?by Qdeathstar - CoreXY Machines
maybe sounds like cheap linear bearing rattling aroundby Qdeathstar - CoreXY Machines
Won't ever be able to make crepes if you wait till you get your culinary degree to make crepes. Crepe while you can. The best way to learn is to make mistakes.by Qdeathstar - CoreXY Machines
yikes, 4 grand for deldrin wheels and twine on 2020 extrusions. That is too expensive.by Qdeathstar - CoreXY Machines
Yes, I plan to use the 2" aluminum extrusion, like you did, then bolt that to the t slot using the t nuts. I planned it out on inventor as much as I could suffer (mainly just to be frame size). I opted just to buy the t slot new, as I can get it cut toby Qdeathstar - CoreXY Machines
Could you take a picture of your belt tensioning method? I saw you were planning to cut slots on the motor mounts so you slide it back, is that you need up doing? On my design, I plan to use the two inch aluminum extrusion like you are, but I'm going to mount that directly to t slot. Do you think two m5 t nuts is good enough to secure the motor?

Does the uv lighting do anything but make it look cool? (Which I agree, is important)by Qdeathstar - CoreXY Machines
