So i was wondering if anyone would be interested in this idea i have. I want to create a dual encoder user interface to control x and y on steppermotor drives. The idea is pretty simple wire up a encoder to a driver with step and dir pins. use a terminal to split the pulse output on a output b from encoder to trigger the dir pin and the step pin. output a will just be wired to step. the encodersby TheBoy - Let's design something! (I've got an idea ...)
I have been thinking about the m01 problem and I think we are over thinking. Remember that if we do it this way we are only using the 3d printer board as a i/o slave with no load directly attached. The motors get power through the plc which the m01 wouldn't shut power off from. It would simply stop sending it +step commands until the criteria was met to move on to the next command line so we shouby TheBoy - Developers
Quoteo_lampe Call me stupid, but I don't know what a hmi is. From the context I understood, Plc is some kind of ( widely known? ) controller, stupid but overpriced. You want to build a closed loop stepper control with it. Can you control 4 ( or more ) steppers at once to stay synchronized with one Plc? BTW: When you send the next command line after the last one was successfully, your device wilby TheBoy - Developers
The idea is to make a more user friendly hmi that is programmable by the user. Plc is point click stupid very easy to program so we separate our hmi for our micro controller with plc while sending gcode with the micro controller. We can use the drip feed method with optional stop and encoders to ensure full movement before the next command is injected. So the encoder and counter both count and tby TheBoy - Developers
So i was sittin here working on a moveo/method 2 plc based robotic arm and it hit me. We might not be able to put gcode in the program but we can use the boards a and b outputs to press a counter. That should be able to drive the steps correct? We then send those to a stepper motor driver and have it trickle feed off a timer that resets itself. we then send plc outputs to a stepper motor driver aby TheBoy - Developers
This is very valuable information sorry i hav been dragging my feet. I actually stumbled on the torus design as well (and was just about to make a post about it lmao). I believe inductive magnetism through torodial coils could be used with powder deposition along with two separate induced fields to create a force capable of fusing disimilar metals and leading the way for addman in transmutationby TheBoy - General
and drill bits break. you are saying that because of tool changes you would prefer a less efficient system that you just screw in vs a more efficient system that you have to screw in and then attach components in initial setup. If more heat is transferred into the filament more efficiently wouldn't you consider it a better system?by TheBoy - General
QuoteTrakyan So basically make a heater block+nozzle in one? Downsides are you can't change nozzles and cleaning or unclogging them becomes much harder. You'd also probably run into a few machining challenges. There could be advantages, care to throw a few into the ring? The concept is to get more efficient heat transference through localizing the heat dissipation. Thats the end goal just moreby TheBoy - General
yea so still the same thing just different name. replace up to the thermal barrier.from the left side with one unitby TheBoy - General
QuoteOrigamib Is your question in reference to hotends, extruders or both? Hotend design is limited by size, production method, components (thermistor and heating element) as well as a plethora of other things. The heating block serves a very specific function and its hard to imagine an alternative. As for material choice, the fact that aluminium dissipates heat is a desirable quality as it alsby TheBoy - General
Why do we use aluminum to transfer heat to our extruder head? If we wanted a more even heat transference shouldn't it be a metal that doesn't dissipate heat? Why not just put the heating rod in the extruder itself if it's already on a cnc the extra pocket shouldn't matter. It saves a step reduces production time and can still be sold for the same price.by TheBoy - General
QuoteTrakyan Sounds like you're printing all at once, what you could try is sequential printing, where one part is printed somewhere on the build plate and finished, then you move to another part of the build plate and finish another part etc. That way a failed part has less chance to screwing up the rest of the parts. I think it might also decrease print time since you don't need to constantly tby TheBoy - General
So I'm curious as to how everyone else prints in batches and what is the method you prefer? I have printed parts in batch runs successfully. But I don't like the clean up of parts and the high failure rate. If one part fails I would prefer it not to affect the other prints. How do you guys print in batches? I always try and run fast and hot to reduce stringing on PLA. 2-3mm Build heights to taby TheBoy - General
Hi I am currently pursuing inkjet and hybrid cnc for opensource, You have a very similar setup up as the hybrid. Have you looked into RAMPS and the mega? I am looking at it and I feel it could run dual extruders. Aux 2 has the pins required. Anyways I am interested to hear your thoughts on running two separate cncs off one mega.by TheBoy - Developers
