Kossel. LumenLab micRo postmortem. Hi All, LumenLabs is dead.
They died over a year ago, and their machines are not for sale. Their last tweet was in December of 2011, so they’ve probably been dead since January of 2012. Their website is now owned by a domain parker. I’ve been watching LumenLab for a long time. Here’s my personal opinion — why I believe their company either failed ( or at least, had public relations problems. Now, I lust after their robot — so what’s the design problem? So, from the get-go, they had a serious problem. Which brings me to the second problem — they ran the business like a couple of guys and a machine shop. Pissed off customers — people have paid for the thing, and they don’t get the thing in a manner they consider timely. Backorders of this type have 4 possible solutions: Raise prices — have your supply meet the capacity of your shop, and only satisfy the demand you can satisfy comfortably at your current scale.Outsource — have other companies help you make the part.
Thanks, Imran Like this: Doh! Kossel/Rostock bowing/cupping Issue (and then some) It sounds like you need to decrease DELTA_RADIUS.
#define DELTA_RADIUS (DELTA_SMOOTH_ROD_OFFSET-DELTA_EFFECTOR_OFFSET-DELTA_CARRIAGE_OFFSET) and before that line, the values are defined for DELTA_SMOOTH_ROD_OFFSET, DELTA_EFFECTOR_OFFSET, and DELTA_CARRIAGE_OFFSET. // Horizontal offset from middle of printer to smooth rod center. #define DELTA_SMOOTH_ROD_OFFSET 175 // mm // Horizontal offset of the universal joints on the end effector. #define DELTA_EFFECTOR_OFFSET 33.0 // mm // Horizontal offset of the universal joints on the carriages.
#define DELTA_CARRIAGE_OFFSET 22.0 // mm So, for the default code, DELTA_RADIUS = 175-33-22 = 120 Now, if you are experiencing interference at the center, you want to adjust any of the three variables to make the math work out so that DELTA_RADIUS is smaller, say 119. #define DELTA_SMOOTH_ROD_OFFSET 174 // mm then DELTA_RADIUS = 174-33-22 = 119 Likewise, if there is a big gap at the center: #define DELTA_SMOOTH_ROD_OFFSET 176 // mm then DELTA_RADIUS = 174-33-22 = 121.

Rostock. Rostock Release status: working Rostock is a linear delta robot 3D printer prototype, built in 2012 by Johann in Seattle, USA.
Several variations have taken root, including: Kossel, Rostock mini, Rostock MAX, Rostock-Montpellier, Rostock Prisma, Delta-Pi, Cerberus, cOssel, Cherry Pi and ProStock. Both the MOST delta and their Open Source Metal 3D Printer also uses an inverted form of this design. Design Goals Build volume: 200x200x400 mm (8x8x16 inches). Videos Firmware Many firmwares support Delta printers out of the box. Frequently Asked Questions How do you adjust the height of the print surface ? You can adjust the following line in Configuration.h and then recompile and upload the firmware: // The home position of the print head. // For Rostock this means top and center of the cartesian print volume. For micro-calibration, use the adjustable endstop screws in the vertical carriages, see #Calibration above. Should the heat bed be mounted on top of a piece of insulation or cork ? No. Future.
