use a volt meter and test for the correct signal at each pin at the end of you parallel port, or at each terminal of your breakout board. If the signals are not making it out to the breakout board,...

That Aspire package looks like a top shelf product. I'd have to save my quaters for a long time to get that one.

So I have gotten my scratch built CNC gantry table just about finished up. Still needs a little tweeking and tuning (hold downs + sacrifical board, home switches, tramming the spindle....and much...

I graduated with a BSME in 2007 from Wichita State University. I have been working as a Mechanical Engineer since then (plus some co-ops and internships since 2005). I have worked in the Automotive...

I have a keling 36V 9.7amp switching power supply. From what I understand, you should always leave a little bit of headroom while using a switching power supply. In other words, I guess I am not...

Energy cannot be created....nor destroyed.....Unless you can move a mass at the speed of light squared according to my buddy Al Einstein. He is one fantastic man!

As I continue to build my machine I often find myself looking through keling's website dreaming about the next cool thing I need to buy for my CNC.

Recently I have noticed that Keling sells some...

Looking to upgrade my x-axis stepper motor to move the gantry on my homemade CNC router table and I noticed that Keling offers this neat looking stepper driver + power supply in one convenient...

just to double check my units???? Inductance is given in mili-henry's. I take the 2root of that and multiply by 32 and that gives me the voltage required to achieve max performance? The solution is...

I have also noticed that both of the drivers have a voltage range from 24 to 80V. My current plan is to use an extra 36 volt 9 amp keling power supply I have lying around to power a single newer +...

stepper motor of course

Can motor drivers only be paired with specific motors? For example, I noticed that most of the kits for the NEMA34 1200 oz-in motors are often paired with the KL-9082...

I recently purchased a NEMA 23 3 axis stepper motor kit from Keling...The one that has the 425 oz-in motors, KL4030 Drivers and the 36V power supply. Currently the electronics have been wired up and...
