Re: (Help) I'm starting to work on Compiling Custom Marlin could use help - 11 months ago

Hey Viktor thats an interesting way of doing the extrusion, I'll keep it in mind but the 445 value should work to get started and that part of the customization to the firmware is one of the easy changes for me to make. The parts I need help with are the offsets/endstop set up to make sure my extruder/nozzle doesnt crash into anything or go printing off the edge of the bed. Are you able to advise

Re: (Help) I'm starting to work on Compiling Custom Marlin could use help - 11 months ago

I just saw that there is a Marlin Simulator. I suppose that could be used to work on my project/another custom printer build in the future. I wasn't aware of that program. Maybe for now though I can get assistance from people here. This looks like an awesome forum I was browsing and saw a bunch of sub forums that I am interested in checking out. Lots of great projects and skilled makers I'm cer

I just watched a video of the Marlin Simulator. I wasn't aware of that program and just learned of it from this post. Pretty cool.

Hi Viktor thanks for reaching out. I do have a value for increased E steps added. That was easy to do. I'm mainly concerned with the X,Y,Z motion as far as the endstops and travel limits. All of that is what I have a feeling I probably didn't get correct. I'll post again shortly with the initial attempt I made with firmware and a description or the printer, pellet extruder and what I'm trying.

(Help) I'm starting to work on Compiling Custom Marlin could use help - 11 months ago

Hi Rep Rap community. I have a project that I could use help with. I'm quite good at functional printing and understand slicer operation pretty well. I only know the most basics of firmware though and could use a little bit of help in that area. The project is a Creality CR10 V2/3 with a mini Pellet/Granulate extruder. I'm most of the way there. I've got all the hardware and measurements to i

Mini Pellet Extruder - 2 years ago

If there is a better (more exposure/more appropriate) place for my post please let me know. I purchased components recently to build a mini pellet extruder. I'm thinking it should work for melting and extruding powder which is the plan. It's branded as Funssor and similar to this one branded as a Polished3D The difference is the "barrel/heat sink" should be brass with the version I purchased

Re: Thermoset Type Plastics used in a extrusion type printer? - 2 years ago

That's what I thought. I imagined it's detrimental to thermoset types of polymers. To what degree though would be interesting to determine.

Re: Thermoset Type Plastics used in a extrusion type printer? - 2 years ago

Ok that's an interesting piece of equipment. I have been trying to "think outside the box" regarding plastics and how to develop new processes for producing material such as filament or print heads that can utilize new materials. The specific material/process I want to develop would involve using powder form plastics but not in the same way as SLS. I'm quite certain the equipment I would be u

Thermoset Type Plastics used in a extrusion type printer? - 2 years ago

Would it be possible to use thermoset resins such as epoxy and polyester in an heat/extrusion type printer say with polyester or epoxy powder in a screw type extruder? Obviously temperature would need to be higher than thermoplastic to extrude but would be possible? What about material strength after such a heating/cooling cycle(s)?

Diyouware if you can incorporate a high volume of fibers such as fiberglass into the extrudate then you would have a very desirable process/machine.
