Can anyone suggest a good one

I am looking at possibly buying this one

http://www.toshiba-components.com/docs/linear/TB6600HG_en_datasheet.pdf  this data sheet?

Do you think i should find a lower voltage supply?  like 36v

i saw that, except the Toshba spec is 50v for the chip and in the documentation that came with the drivers states 50v

Hello martin,  2 things i have found this morning that makes a difference to the smooth running

Turn off watchdog on relay 1, its done by going to  Config > config plugins > hycnc_4l, this made a huge difference

Set the voltage correctly on the motor driver to match the current required for the nema motors, have you looked at this yet?

There is a pot on board that will adjust the current from .5A to 4.5A http://www.mib-instruments.com/servlet/the-3453/TB6600-Stepper-Motor-Driver/Detail

Thank you

Also check the pitch and quantity of teeth  on your pulleys, it would seem that the steps / mm are very critical, i changed mine by -.5 and -.6mm on the other, and i got really weird results when drawing out a block of 4x4 25mm circles

what happens if you disconnect the belt and just turn the motor, does it still blip? also what voltage does your power supply kick out?

no skipping, but it made noises like it was struggling, if you push you x axis by hand with the power off, it makes the same noise, i wound the current down and switched to clean vista, that sorted it.

 i have built mine differntly to yours, the motor drivers and breakout card are mounted on the x axis.

I am not sure where all the noise comes from if it does at all, however bunching all your cables up is not a good idea noise wise.


maybe someone can enlighten me
