| ==== Printhead modification ==== | ==== Printhead modification ==== |
| The omni200 printhead is connected via a strand of wrapped cables which are attached in a holder at the beginning and at the end. The wrapping consists of some kind of fabric sticky tape and does not really provide a means to control the bending radius. To improve this, it was decided to swap the cables out for an FFC-cable, which on it its own provides enough flexibility and sturdyness to carry its own weight and still bend evenly under all circumstances. | The omni200 printhead is connected via a strand of wrapped cables which are attached to a holder at the beginning and at the end. The wrapping consists of some kind of fabric sticky tape and does not really provide a means to control bending radius. To improve this, the best would be to swap the cables for an FFC-cable, which on it its own provides enough flexibility and sturdiness to carry its own weight and still bend evenly under all circumstances. |
| |
| Another major advantage of using an FFC-cable is that it offers a few more wires, which can be used for future extensions, like a laser-based proximity sensor (see [[https://electronics.stackexchange.com/questions/94508/improve-3d-printing-via-distance-detection/615927#615927| here for a description and pictures]], or a filament runout sensor. | Another major advantage of using an FFC-cable is that it offers a few more wires, which can be used for future extensions, like a laser-based proximity sensor (see [[https://electronics.stackexchange.com/questions/94508/improve-3d-printing-via-distance-detection/615927#615927| here for a description and pictures]], or an additional filament runout sensor. |

| The system consists of two circuit boards, one to be attached to the rear of the inner housing and one to be mounted on the printhead itself. The circuit board at the printhead kept the same connectors, so further crimping of cables was not required. At the other end of the FFC-cable, the circuit board which was mounted at the back plate, required the cables from the controller board to be shortened and crimped. | The main modification consists of two new circuit boards, one to be attached to the rear of the inner housing and one to be mounted on the printhead itself.

| This solution should be an in-place replacement, without changing something substantially to the design. | This solution should be an in-place replacement and does not require any soldering of wires. Only the header needs to be soldered to the heater of the build plate. The new connector will allow a current of 9A per pin. Combining 3 pins for heating on positive side and similar on negative side, should be enough, The two remaining connections can then be used for the thermistor. |

| * overextruding at first layer: Try to keep Cura setting "Initial Layer Flow" to 100%, but increase the Z-offset for the first layer. | === Over-extruding at first layer === |
| * uneven layers: | Try keeping Cura setting "Initial Layer Flow" to 100%, but adjust the Z-offset for the first layer. Calibrate the E-step setting for the extrusion stepper motor. In my case, with a factory default setting the "G1 F100 E100" command extruded only 85mm instead of 100mm filament. Only after a correction (with sending "M8011 0.01373" and M8500 to save settings), the extrusion was exactly 100mm. Also note that after much empirical testing, the first layer distance to the build plate after homing had to be set to 0.07mm, using the supplied spacer gauge: filament sticks well to the build plate and the first layer revealed evenly strokes of filament. |
