Re: Extruder keeps slipping

Could this be a loose or broken stepper motor wire?

Re: Tool Change script for S3D

Sorry for the delayed response. https://photos.app.goo.gl/RjNPdJzA8rp9iK9w7 https://photos.app.goo.gl/RjNPdJzA8rp9iK9w7 It works well enough. Slicers didn't have the priming tower feature at the time I was making this, so the transitions are not as good as they should be. My experiment with soluable...

Re: Bed won't heat...

My printer is now back up and running, but with the firmware on the Rambo, I had to home my Z-Axis in a funny way. Basically I have to issue M18 to turn off the motors, G4 P6000 to wait long enough for the z-axis to finish dropping to the bottom, G92 Z207 to set the current z-position to 207mm. Afte...

Re: Bed won't heat...

Ok, so after printing a replacement motor mount on my Mosaic, I was able to get everything physically installed, however I still have a problem, and I think it has to do with my machine home toward z-min rather than z-max. As soon as my z endstop triggers, the firmware resets. Looking at the termina...

Re: Bed won't heat...

So I'm working wiring up the 24v power supply and v3b->v4 extruder upgrade, and I get to the point where I'm supposed to use the 4x M2-18 bolts to connect the mounting plate to the belt clamp. Unfortunately, the nuts in the clamp seem to be M2.5, so my bolts are too small. Should I have received 4x ...

Re: Layer shifts sometimes

Does the enclosure include your electronics? You might be getting sporadic thermal cutoff on your stepper drivers due to the high ambient temp caused by the enclosure.

Bed won't heat...

I was in the middle of a print when all of a sudden I noticed that my bed temps had started dropping. After the print was complete, nothing I did could get the bed to start heating again. Measuring the voltage across the bed power pins, I get 12v. However as soon as I apply a load, the voltage drops...

Tool Change script for S3D

I've designed a dual extruder that has only a single hot-end (inspired by the palette). This eliminates the problem of getting the offset set correctly. However since both filaments go into the same hot end, the tool change g-code needs to retract the old filament to make room for the new filament. ...

Re: Wow, this is a nice damn printer!

Actually all they need is to dump the jam nut, and use a spring to take the slop out. The tension would induce enough friction to prevent it from vibrating out of position, but it would still be easy to change.
