General Mach Discussion / problems understanding PWM and spindle settings
« on: November 19, 2011, 12:48:28 PM »
Hi
My friend is having some problems understanding what the settings should be in the motor tuning and PWM settings in mach three.
he purchased this. http://www.ebay.co.uk/itm/160673143941?ssPageName=STRK:MEWAX:IT&_trksid=p3984.m1423.l2649
Nice bit of kit, unformtunatly, you could fit the instructions on the back of a machbox, and then there in chinglish. We have mannaged to muddle our way through by reading the mach 3 docs so far but are stuck getting the spindle to work properly, or at all sometimes.
the spindle is 1.5kw chinese http://www.kelinginc.net/KL-1500.PDF
anyone know what the steps per/accel and vel settings should be for this.
Furthermore, we are struggling to understand what affect the PWM has, any pointier. We have his pc running at 25,0000 hz all other drives are working fine.
any help or pointers would e very welcome
the spindle seem to either not work at all ( Midi command ) or work occasionaly, when it does work, it goes through the spindle callibration ok, when it doesnt work, it says either pwm to low bumped to minimum setting or to fast for pully. We have the pully set up correct i thing ( min 6000 max 24000 ) althoug we have been messing about wit the motor tuning settings.
