Should not be any different than on another type of printer. There's some effector designs for this on thingiverseby Joeybane - Delta Machines
Here are the settings i use: #define DELTA // Make delta curves from many straight lines (linear interpolation). // This is a trade-off between visible corners (not enough segments) // and processor overload (too many expensive sqrt calls). #define DELTA_SEGMENTS_PER_SECOND 200 // Center-to-center distance of the holes in the diagonal push rods. #define DEFAULT_DELTA_DIAGONAL_ROD 230 // mm //by Joeybane - Delta Machines
Seems like your delta radius is off. Have you done the flatness calibration? Before you do it, you should try to get your bed as level as possible, I used a right angle, and put washers under the mounts to get it as level as possible. - Check that the nozzle touches the bed at the same z-height at all three towers + center. If center is higher, you need to increase #Delta_smooth_rod_offset if i rby Joeybane - Delta Machines
Can't you just move the endstop down? The center will be lower, and you will need to adjust the delta radius. That's how i did it in Marlin, i assume you can do the same in Repetierby Joeybane - Delta Machines
The extrusions are 300mm. I'm thinking of using countersunk screws on the bed and using a glass plate on top(already bought a borosilicate glass plate) I should be able to use all the build area if I then put on longer rods and move the powersupply. How long rods would i need to utilize the full build area on this machine? I may win some build height back if i use an effector like this one: Infilby Joeybane - Delta Machines
Well, this is how it looks like at x-75, not much more to go on. In the other direction I can go all the way over the edge of the heatbed if i want. I may buy some 250mm rods eventually 250mm rodsby Joeybane - Delta Machines
I figured it out. sort of. The 230mm rods are not long enough to reach the advertised 210mm build area! I set the radius to 75, loosing a lot of build volume in the process. I also had set repetier up for 210mm build area. However, the xy distance is something i'm still working on. I took all the measurements and plugged it in the newest version of marlin (with G30 autotune) Calibrating flatnesby Joeybane - Delta Machines
I had to invert the x, y and z directions in my firmware, or rather, remove the inversion. Before i did that all it would do was crash into the bed. #define INVERT_X_DIR false // for Mendel set to false, for Orca set to true #define INVERT_Y_DIR false // for Mendel set to true, for Orca set to false #define INVERT_Z_DIR false // for Mendel set to false, for Orca set to true Also make sby Joeybane - Delta Machines
I ran 100mm in the z direction, and it's spot on, so i think the steps per unit is fine, i will double check. Yup, it moves correctly in the z direction. 230mm from center to center yes. The effector offset is 25mm, which is the numbers in the firmware.by Joeybane - Delta Machines
Thanks for the reply. I'm not moving a single tower, just using repetier and moving it by clicking the buttons. The firmware stops the movement in some directions, but in others it crashes. When the firmware bstops it, the coordinates in repetier is off, and i have to home it again. the problem first appeared when i calibrated the flatness at these points: g0 x0 y0 z5 g0 x0 y105 z5 g0 x-90.23 yby Joeybane - Delta Machines
Hello. I have recently gotten a Folgertech kossel 2020. I have built it, and calibrated it, so now the nozzle is a papers width over every part of the heatbed. Have printed a calibration cube, and the xy direction is too big. The problem is that sometimes when i manually move x and y, one of the carriages just continues down and crashes into the base. This has wore out my rod ends, and there isby Joeybane - Delta Machines
I had the same problem when i assembled my printer. I loosened all the bolts slightly, and forced them together, then tightened everything up. The error has been evened out on all the joints, it looks good to me. But i do agree that the cornes should be at 60* for it to be right. That, and using t-slot screws with bolts would have made everything easier to assemble. Easier to turn the nuts, andby Joeybane - Reprappers
