brushless motor for milling spindle on servo port
Hi, I have a ramps 1.4 and an rc brushless motor that I am thinking of using for a cnc spindle on my machine. I know that brushless motors are controlled in a way that is similar to servos. I was...

You need an RC electronic brushless speed controller. This has a 3 pin input which connects to where you would plug a servo. There are 3 output wires which go to the motor. Another 2 wires go to the...

Yep shouldn't be a problem at all, they would just be in place of extruder motors

wondered that myself, and presumed their mega has bad io lines, or the board inter connects are bung. So I answered presuming they know what they wanted. They seem happy with the results. So all good.

Yeah I have an ESC with the signal wire. But can you control the speed using gcode? I have read that the servos are used for auto bed leveling. How could I utilize the servo port during the milling...

You could, but 3.75 step angle is half what you would normally use. Plus at 0.5a I should think they would be very low on torque

Hello, Excuse Me if someone has already put up a thread about this. I am using Arduino MEGA 2560 + RAMPS 1.4 While trying to test my Endstops, i dont know how, but suddenly by z axis stepper driver...

Sounds like you shorted the +5V pin to the ground, and killed the Arduino's regulator. There is a +, - and S pin on each endstop connector. If you use switches and connect them the wrong way around so...

Hey Cefiar. Thanks for your help. I have connected the end stops right to S and - I dont know how,But I my Stepper Driver on the Ramps 1.4 blew off Will that possibly cause any damage to the Arduino...

The computer doesn’t actually talk to the Arduino 2560, it actually talks to the tiny Atmega 16U2 (presuming you have a R3 board) The Atmega 16U2 does all the fancy USB to serial conversion. Since the...

Hey Dust Your doubt kind of seems right. It is the ATmega, which is heating up. 5V on a 5V pin, On the RAMPS ? I am connecting the Arduino only through a USB Cable, without the ramps pinned onto it.

Probably best are the ones that have short tracks and small number of vias. Each via adds a parasitic capacitance maybe 20-30-40+pf which may not be all that much for normal logic tracks, but still...

OK, one more question about connectors. I'm trying to figure out the latching 0.1" headers. The picture on reprap.org shows standard 0.1" pin headers. The PCB footprint and Digi-Key part number called...

Thanks lazzymonk, that gives me more confidence! I had a look at the specification pdf just now - the motor is rated at 12V 0.4A. Would it actually receive a full 12V from a pololu A4988 driver?

So I like this x-axis design :[www.thingiverse.com]. The dual-X carriage idea is pretty nifty. Only problem is that I would need to break out some pins and solder up a drive board for the second...

12V 0.4A seems to be the wrong kind of motor 12/0.4= points to a 30 ohms coil. Imo find something like ~1~2~3 ohms coil. The usual and good motors are rated like 2~3~4V and 1~1.5~2A something more...

I tend to build prototypes using ordinary 0.1" headers, it's cheaper and for motor connectors easier to swap direction. The intention was to allow any type of connectors - latching/non-latching,...
