how have you configured spindle in mach? motor tuning- saved?
ports and pins - spindle setup?

re galil movements. you have to set acceleration, deceleration too before using pr1000 and bgx etc. worth burning these in.
make notes of what you burn in to change them later. took me ages to work out why i couldnt get full speeds!

do you have the spindle configured in motor tuning in mach? speed, acceleration etc
is there a feedback pulse from your vfd? or are you going to run the spindle open loop?

your spindle may not respond to tl1 1 volt output. burn it at 9.98 for axis 4 on galil (your vfd may be set for minimum rpm for example 8000rpm )

oh. look what i wrote in my last post "make sure you follow the book carefully re servo first tests ie. limit the current etc as the motors can really move.... in the wrong direction!

while your testing its worth setting the axis to torque limit tlx2 for example gives max 2v out on x axis instead of maximum of 10volts. this stops you from shooting into limits and breaking things! you must send bn command to burn it.

re limit switches. usually there is also a shorting relay that after power is switched off, shorts the motor wires together to perform dynamic braking of the motor. check if its there and you havnt wired it out?
have you wired the limits into the galil? the galil can be set to stop the motor dead when limit is hit. and will then jog only reverse off limit.

re movement direct from galil. you must write acceleration/ deceleration time ,  distance pr then bgx for begin movement x etc etc
this is done in side window on left. its in the manual

i couldnt get galil tools to work either. i use smarterm. (think most people have found this)
dont know re printer driver. send crouch a pm or ask artsoft direct. ( i have printer driver installed on mine but its not chosen when it loads by selecting plugin once galil plugin is configured and registered with mach)

one thing you will notice is that mach wont show moves as its waiting for feedback from the galil . (all works fine when motors/encoders are correctly working)
make sure you follow the book carefully re servo first tests ie. limit the current etc as the motors can really move.... in the wrong direction!
luckily my first tests were on small yaskawa servos on the bench. was well worth doing to get your head around everything

dont know that controller.
download and read the manual.
you will need it to get it registered on pc and set everything up anyway.

its easier if you print it off if you can. its a pain working off pdf when your setting evertything up

i just posted that as a price comparison. obviously its up to you to make sure your going to be happy with it and the terms of the sale.
i have dealt with a few of the asian companies on ebay and have always got a great deal.
shipping doesnt really matter here as i usually have to buy from the states or china/korea, singapore etc. their postal system is quite fast. its the UK side thats slow!
i bought 5 galil icm 1900 from singapore, they arrived in under a week.

contact these guys and see what they have

i have had lots of galil items from them cheap! eg. 5 axis controllers 1750 isa bus for $130 etc

maybe but i would have to buy new spindle drive etc. the problem i have is i only have a "flying" 80amp 230v supply to my home as im in the sticks. electric compant wanted a fortune to upgrade the supply.
my spindle is 7.5kw 380v 3 phase so i would be pushing the supply to melting point with the other things running here too.

besides most of my equipment requires 3 phase. to get it i just press the generator start button! no expensive electric bills , just pay as you go diesel
