stepper wiring
I bought some busheng 17hd34008-22b nema17's with plugin leads, but the way they are colour coded is not same as my others, I realise the colour doesnt matter and assume they are wired to work, but...

There is an easy way to check. At the connector that will plug into the board, short together the two wires at one end of the connector, such as r and b in your case. This should make the motor shaft...

Cool thanks, seems things are wired to work 1&2 3&4 at the ramps end, this little tip will also help me sort out those other steppers that came with no connections, and the others with the...

I agree, stepper motors should always be wired to the electronics with locking connectors. This improves printer reliability, and disconnecting a stepper motor that is powered up may blow the driver...

Thanks for the molex info are they slightly different from the 3 & 4 pin connectors that come on the endstops? or same, luckily I went with single Z motors on my printers, so far so good 3...

QuoteMechaBits Thanks for the molex info are they slightly different from the 3 & 4 pin connectors that come on the endstops? Which endstops? Endstop wires often come with non-locking black...

just the normal 4 pins for the mech endstop which lock, and the 3pin opto ones which also lock, but as you say your molex ones fit but lock differently, but I have the answer the molex are different...
View ArticleThinking about increasing motor voltage
My 12V PSU gave up and maybe it is time to increase the voltage. I'm wondering. if I use 24V volts for motors and about 1A avg current with tmc2100 driver, do I really get double output from motor or...
View ArticleRe: Thinking about increasing motor voltage
What you get from increasing the driver supply voltage is that the motor torque is maintained up to higher movement speeds. This is particularly useful for delta printers using 0.9deg/step motors. The...
View ArticleQuestion about behaviour of stepper motors in manual mode
hello I am new to the world of 3 printers. I tried to use ramps with arduino and marlin firmware, and I began to give a command in manual mode to one of steppers. I tried both repetier host and...
View ArticleRe: Question about behaviour of stepper motors in manual mode
What you measured seems normal to me: depending on the position, one coils gets more and the other less current (at full step positions one coil has all the current and the other none). But it's not a...
View ArticleRe: Question about behaviour of stepper motors in manual mode
thanks for replying. but I want to ask, Why in stand still, there are sometimes noise, and other times no noise? If I understand correctly, if the motor has no noise at standstill, this means that the...
View ArticleRe: Question about behaviour of stepper motors in manual mode
I am not an expert, but I assume that the amount and type noise you hear when the motor is not moving depends on the current and the exact position in which the coils have to keep the axis balanced in...

Hi I am thinking about ordering powerlolu boards. I am curious as to what was the final cost for the 20 completed powerlolu boards?

The formula for P should be P=(RL+XL)*I2 so there is a bit of complexity.

I'm looking for a simple way to power my project. It just has one step motor and is controlled by an Uno R3 and a CNC shield with a polulu. Currently I use a 550w ATX power supply that I cut the wires...

The power plug on the Uno is only designed to carry power for the uno, You will need to power the stepper drivers separately
View ArticleRe: 1 Stepper Motor, Uno R3, CNC, power supply question
Thank you for saving me some trouble, I had no idea. What about if I use an arduino nano on a v4 CNC shield? The same power socket as the R3 is on the v4 CNC shield. Would that be able to work?
