Quotehayseed_byte Quotepiper3d the_digital_dentist, you have some epic job documented in this thread. Multiple innovative solutions. People may read it as a book on how to design your own printer. Congratulations on a great job! I basically used this thread along with his blog as an instruction book while I was designing and building my modified d-bot. I really do feel like a book would be a gooby widespreaddeadhead - CoreXY Machines
Nice to see there is better hotend and part cooling fans with this version. With many people moving away from cantilevered beds and smooth rods, is there any reason you decided to keep them other than price? Thanks!by widespreaddeadhead - CoreXY Machines
The best 'hairy lion' I've seen yet!by widespreaddeadhead - CoreXY Machines
Quotetgmorris99 In addition to checking the belts, etc. also make sure that the X & Y axis are perpendicular to each other. If they aren't you'll see similar issues. The X axis can be squared to the Y axis by adjusting the belt tensions. +1 for this.by widespreaddeadhead - CoreXY Machines
Before I noticed the mirror, I was thinking, this guy is building two of these monsters!? Beautiful design, came together looking very clean. What are the wheels the belts run on?by widespreaddeadhead - CoreXY Machines

Following this on Thingiverse and here. Would love to swap out 2 of my 200mmx200mm printers for one of these!by widespreaddeadhead - CoreXY Machines
QuotelukaCX *khm* look at the photos in the first post I still can't really see anything, are there guides on the sides of the bed?by widespreaddeadhead - CoreXY Machines
I don't have firmware for that setup, but maybe I can help with the firmware. What issues are you having?by widespreaddeadhead - CoreXY Machines
Looks like they move independently, the belts for one run along the top of the X axis while the belts for the second run along the bottom.by widespreaddeadhead - CoreXY Machines
I mount mine above, so that when it hits the endstop its at Z=0. Y rear should be MAX not MIN.by widespreaddeadhead - CoreXY Machines
Misumi has some, but they are expensive. If you live in the US you can have them ship to you directly.by widespreaddeadhead - CoreXY Machines
For the X and Y, I guess it depends on what you have in your firmware. My firmware is configured to use the full range for the X and Y, which for me is 220X200, even though I only have a 200x200 bed. However, if your firmware is set for just 200x200 in the X and Y, you can just place the endstops at min or max so that your nozzle just meets the corner of your bed, which if your facing the printerby widespreaddeadhead - CoreXY Machines
That might be a good starting point, but eventually you should tune them according to how they run, if they are running too hot and skipping steps, tune them down a little. If they are too tuned too low and the extruder is clicking, tune them up a little.by widespreaddeadhead - CoreXY Machines
I have those vibration dampeners on my Fusebox X and Y motors and I guess it helps reduce vibration when running at higher speeds, but my printers are still noisy just like you mentioned in the first comment. First I would check to make sure all the axis' are square, so that it's not binding a little bit causing noise. Second i would guess, and what I suspect is my issue also, is that we're usiby widespreaddeadhead - CoreXY Machines
Quotedthomas6184 yeah, I have to reconfigure the firmware for the printer, its running a basic repetier setup just to test the motion. As for the endstops, I have 3 leads red, black, and green. I had them plugged in with the red facing the edge of the board and the green facing the stepper drivers. Flip them around, that is the incorrect way. Red should be facing the the drivers.by widespreaddeadhead - CoreXY Machines
Def. try again with tightened belts. If you have a multimeter check the voltage on the drivers and make sure they aren't too low or too high. Are the motors moving they way they are supposed to? I mean when you tell it to go left/right/back/forward does it actually goes left/right/back/forward?by widespreaddeadhead - CoreXY Machines
Wow, that is some nasty noise, sounds like a lawn mower! Does the carriage move freely when the motors are disabled? Sounds like some binding is happening.by widespreaddeadhead - CoreXY Machines
Quotedc42 It's as I said in the other thread, you need to swap the X and Y motors, then either reverse motor connectors or change INVERT_X_DIR and/or INVERT_Y_DIR until the head moves right with increasing X and away from you with increasing Y. You will also need to tell the firmware that your Y endstop, which I assume is at the back of the printer, is a max endstop instead of a min one. The homiby widespreaddeadhead - CoreXY Machines
Thanks for the great info! Double checked that against my speeds, and in the process realized I have a 0.8mm nozzle and not a 0.6mm like I had in my settings. Changed that and adjusted speeds according to the equation. Running some test cubes now at 0.4mm layer height, and they're looking good.by widespreaddeadhead - CoreXY Machines
Changed to 50mm/s and changed the seam to aligned instead of random, and it's better. There are some holes in the walls around the start point of the layer, not sure about them. There are a few artifacts that I'm sure I can lose while I test my retraction settings.by widespreaddeadhead - CoreXY Machines
What speeds and temps are you running PLA at? I've got a Volcano hotend and running at 200C and 100mm/s. It's producing walls with spaces in them. I tried upping the temp for the hotend in case it couldn't keep up, but the issue persists.by widespreaddeadhead - CoreXY Machines
Quotethe_digital_dentist Something else occurred to me. I have been planning to build the CoreXY machine's Z axis with as much as 1 m of travel. The problem, of course, is that the machine would be very tall and a little difficult to transport to places like the Maker Faire. That got me thinking that since the coreXY mechanism is modular, I could build two different assemblies, one with a shorby widespreaddeadhead - CoreXY Machines
I also think that big fan is going to mess with the bed heater when you install one.by widespreaddeadhead - CoreXY Machines
Why not just use a print cooling fan and adjust the time per layer on smaller prints?by widespreaddeadhead - CoreXY Machines
Flashed 400 steps, but it was still reading 1600, so I sent M502, then M500 like FA-MAS said and it worked! Z axis is now moving correctly, time for calibration! Thanks everyone!by widespreaddeadhead - CoreXY Machines
I check the jumpers and as far as i can tell they were seated just fine, either way, I replaced them with the spares I had but the problem persists. M205 returns 1600 as the steps/mmby widespreaddeadhead - CoreXY Machines
