Mechanical Endstop
Hello, I buy these endstops Mech_Endstop-D.jpg When I go to connect I fail to make them work, and try all forms and does not recognize, but testing continuity with the multimeter I know these are...

You want to change the max speed and acceleration values in your firmware. This might slow it down appropriately.
View ArticleRe: USB Communication with Computer PSU vs 12v Supply
Most likely it's a diode or fuse on the USB +5V line on the RUMBA (or possibly even a track). I'm not particularly familiar with the Rumba schematic, but that is what I'd be looking at.

Where did you buy them from? If an eBay seller, please link to them? I ask because there has been a few clones that don't quite work properly. A post that might prove useful is this one (the last...

As far as I can tell, initial confusion in that thread was caused by assuming the Makerbot pinout has Pin 1 at the "top", in fact according to Makerbot schematic Pin 1 is at the "bottom" on their...

I am working on a revision of the Decapede board [reprap.org]. The Decapede is spec'ed for 24A total continuous at 24V. I think that is doable with 2oz copper and generous traces (rule of thumb, 100...

You could try the mini blade auto fuse. Not sure with the 24 v if they would be useable in you applacation, but they are small and easy to replace being blade style, the footprint is no bigger then...

Thanks for the reply cefiar. Could you suggest how I could do this without reuploading the firmware each time I change it. And what is a reasonable acceleration that would slow it down?

Double check that the enable line is being held low until you want motors enabled. The main thing if I recall correctly is to have 5V up and stable before supplying Vmot, and then enable the drivers....

Has anyone ever tried to run a brushless fan from ramps 1.4? I have a few that I believe are brushless because they have a white signal wie in addition to red and black wires. I would like to use one...

Got it working. It was an easy fix. I feel like an idiot like I always do with electronics. I had the wires for each coil on the wrong spot on the drivers. I thought the outside two were a coil and...

They are easy to use. In fact they are the most common type of fan. The extra wire is just an rpm sensor and can be ignored. You can plug one into the 12v aux pins between the fuses and the x axis...

Thanks for the help everyone. I managed to acquire a replacement from reprappro after emailing their technical support so I know I'll get the correct thermistor. Hopefully I'll be printing very soon!

Really? I didn't think it would be that easy. That's awesome. Thanks lazzymonk. I have read that you can wire the fan to the D9 terminal and you can control it with g Code. Is this possible with the...
