Thanks Ikcl, desynchronization is a total no-no considering how this printer will probably have 3 day prints on a frequent basis due to the size. Like I said, I already have a belt-motion system in place but with such a long z-distance, I need to prepare for some lagging on the opposite end of the motors. If after testing with the current belt setup it still does not work, would you advise thenby rodrigo - RAMPS Electronics
Well of course it is not really budget friendly, we just want to minimize unnecessary costs by optimizing the design. I do have 24V taurino and ramps premium.by rodrigo - RAMPS Electronics
Thanks for the fast replies. I actually do have some nema 23s available but i would like to first exhaust other options with the 17s. I currently have a setup where each motor drives both the top and bottom section of each of the 2 vertical rods which move the y axis however, i had some movement issues yesterday morning with lagging. After untightening some v wheels and increasing the current theby rodrigo - RAMPS Electronics
Hello, I want to know if it is possible to attach 4 motors to one ramps slot and if so, how? I have a ramps premium and nema17s at 1.68 amps/phase. I also have drv drivers and some TB6560 (3A at 24V) if necessary. The reason why is I am designing a massive 3d printer for a research group and would need 4 of them to drive one axis.by rodrigo - RAMPS Electronics
Hello again guys, So I finally got quite far with the printer and most components have arrived. Right now I have the gantry built and am testing the motors but I have two issues as of now. First, the steppers heat up quite a lot and really fast (maybe 60 degrees in 5 seconds) and I suspect it might have to do with the PSU being 24V. I adjusted the stepper current knobs beforehand to be half theby rodrigo - RAMPS Electronics
I'm actually using a Taurino Power with a RAMPS Premium and they should be able to handle 24V . I am ordering also a 24V 350W PSU which I am not totally sure is necessary as I don't know what the rated voltage VDC/phase means (the NEMA 23s are 3.6V 3A and the 17s are 1.68A).by rodrigo - RAMPS Electronics
So there are no RAMPS or TB6560 modules in fritzing, but basically I will use the diagram given by Dots to wire the motors, the first diagram I linked for wiring the endstops and fan, and this for wiring the second X movement motor. Only one question remains, how do i know if my components are 24V compatible and how do >I make the change from 12V to 24V?by rodrigo - RAMPS Electronics
Hmm ok then, I guess I can use 24V power. This is a project for my university so more expensive parts would also be ok, however one of the goals is to try and manage it as cheaply as possible to study the feasibility of building such a printer on a tighter budget. So far the only "crazy" requirements are lifting 50 kg (which is not even that much considering the Gigabot we have here has a 60x60x.by rodrigo - RAMPS Electronics
Thanks a lot Dirt! So I started checking the TB5650 drivers and they would be able to handle the 3A NEMAs. If I understand right, there is nothing else that needs to be changed right? I just plug them to the ports where the Pololu drivers would have been. Also, are they also good for 1.5A NEMA 17s? I decided for now to use those for the XY movement but still have the chance to later upgrade if neby rodrigo - RAMPS Electronics
Ok it seems I'm basically building a CNC milling kit for 3D printer use (it will eventually have some extruder, just not a melting one) so I came across this amberspyglass.co.uk/wiki/EShapeoko_Complete_Kit however, it does not use RAMPS and I do need the functionality of RAMPS later on. How could I adapt that one to my design?by rodrigo - RAMPS Electronics
Hi everyone, I am building a 1 cubic meter (1x1x1m) printer for research purposes WITHOUT an extruder and heated bed. Basically I am building a gantry with XYZ movement and an acrylic bed. The plate moves up to 50 kg up and down with 4 lead screws powered by one (or two if necessary) NEMA 23 motor with a large timing belt around them in a rectangular shape with the motor's pulley attached straigby rodrigo - RAMPS Electronics
