Issues with KL 5056

[woodchuck5]

I recently built my own CNC machine and bought Kelings 640oz motors, KL5056 drivers and C10 breakout board. I haven't had very good luck with the drivers holding up. Been through 3 since August.

The first one was my fault because it was a hard crash but I'm not so sure about the other two. So....I'm experimenting with a Gecko G203v & trying to test it on the same machine with my existing KL5056's and C10.

I can get all the motors to run by wiring the common on the G203 to ground on the board since the Pulse/Dir common for the KL boards is +5v. I'm not getting any accuracy though (missing pulses?) on the X axis with the Gecko even after a lot of tuning effort then my Z axis is also now acting funny. I've done some research and it's looking like the KL5056 and G203V may not be compatible on the C10 breakout board.

Can someone please confirm this??

Thanks!!

Never mind - I found the issue. After doing much testing I could get the 203 to jog but not cut a part without loosing it's position so I put the old KL5056 back in and it did the exact same thing so I looked at the motor and found the coupling was slipping. Yes you can use a KL5056 and G203 in a system setup like mine but you have to wire the pulse/dir common on the Gecko to ground on the C10 board because the Keling drivers take a +5V com.

Thanks,

I too am using the same driver and motors.

On one axis the microstepping setting is behaving on the other two axes the distance traversed under EMC2 config wizard test option seems to be half of what it ought to be.

I do not have confidence in switch settings or whether in fact the drives are working OK.

I shall figure out a fix for the problem ( alter thread pitch or include a different gear ratio to get the distance correct ).



The confusing bit about the drivers initially was that the paper documentation provides a look up chart for switch settings but then on the front panel of the drive a note defines zeros and ones as switch on and switch off respectively ( inverted logic).

Gave me a lot of headache until i observed the notice. Paper documentation sucks and the tiny note on front panel sucks.

Switch FOUR is not at all defined in paper documentation and only superficially addressed on the front panel of the driver.

Clean up Your act Keling.
