Makerbot replicator 2x extrusion problems
Two of the important installation steps were to save the toolhead offsets before installing Sailfish and then to restore them. If you did not do those steps, or did them incorrectly e. If it is enabled and you makerbot replicator 2x extrusion problems not recall enabling it, then likely you forgot that installation step. You may be able to resolve this with a change to the Makerbot replicator 2x extrusion problems parameters for the extruder in question.
This problem is particularly common on Replicator 2X printers manufactured during or after October For these printers, it appears that MakerBot made an engineering change to their Replicator 2X line and then released them without adequate testing.
With the increased air wash cooling the extruder and makerbot replicator 2x extrusion problems default PID settings, the extruder cannot reach temperature. Alternatively, it may simply be that the heater core for the extruder makerbot replicator 2x extrusion problems question is too weak: In either case, you can attempt to change the PID settings for the extruder.
Do this with ReplicatorG — Sailfish. In the onboard preferences window, click on the tab for the extruder in question: Once the change has been made, power cycle the printer. Then test the behavior. If that does not work, the problem may lie elsewhere. Be very careful about experimenting with the PID values as you do not want to destabilize the heating controls.
Their makerbot replicator 2x extrusion problems, which Sailfish follows for compatability, is not true PID control. Makerbot replicator 2x extrusion problems are printing an old-style print file which has only unaccelerated motion commands. Such print files often use the file extension. Regenerate the print file and ensure that it is a. Fast, violent motion is typically associated with printing at high speeds without acceleration.
If acceleration is already enabled, make sure you are using the correct type of build file. As of Sailfish 4. In ReplicatorG — Sailfish, those new commands are used when generating. If you use an. Note that this will preserve your home and toolhead offsets. You are looking to make sure that the X and Y offsets are not small values or even zero or negative. Should you change the values and again check them, you may not see exactly the values you set. For Thing-o-Matics and Cupcakes, you should run the home offset calibration procedure if you are unsure of what the correct home offset values are.
Loose pulley which slips from time to time. Tighten set screws on all pulleys. Faulty stepper motor wiring, or wiring not well seated in their connectors. Inspect wiring; reseat connectors.
Problems may only exhibit at certain travel extremes. Faulty endstop wiring, or wiring not well seated in their connectors. Electrical noise picked up by endstop wiring and causing false endstop triggers. Route wiring away from stepper motor wiring if possible. Build is too large for platform and an endstop is being triggered causing lost steps. If you are sure that the problem is not mechanical, then it may be that you are running an axis faster than it can tolerate.
The Z axis, especially on a Cupcake, makerbot replicator 2x extrusion problems particularly sensitive to this. The maximum feedrates allowed for each axis are makerbot replicator 2x extrusion problems in the machine definition file used by ReplicatorG.
Those maximum feedrates are specified in units of millimeters per minute. You may need to reduce your maximum federate. After changing a machine definition, you will need to exit and restart ReplicatorG so that ReplicatorG registers makerbot replicator 2x extrusion problems change. However, the primary enforcement of maximum feedrates is your slicer. As such, you need to also set the maximum feedrates in your slicer. How this is done is slicer dependent and outside the scope of this document.
Moreover, you can move it to as many positions as you want, in whatever order you want, as many times as you want. Just hold the extruder carriage and move it to whereever you want to check the spacing between the extruder nozzle and build platform. Use the adjustment knobs under the build platform to adjust the spacing between the build platform and nozzle.
When you are finished, press the center button to return to the Utilities menu. If you are using your own starting gcode, check it for errors.
Note that the G gcode command homes to the minimum endstops while a G command homes to the maximum endstops. Printer-specific homing directions Finally, if the homing commands appear correct in your starting gcode, then check if the direction of motion for the axis or axes has been reversed.
