Hello everyone...Just picked up a 5 by 12 cnc made by bales-atlantic....very rubust machine in great shape. motors are brushed type and discontinued. machine runs a fagor control. would like to bring the electronics up to date as previous owner been having problems finding parts. thinking about servo motors, ac servos in particular ... Looked at a few diff manufactures. dmm tech, teknic, and a few others. trying to avoid the chinese stuff if possible. machine has 3 bayside right angle gearboxes 8:1 which seems to be lower geared than most other machines. The motor shafts are .500...most of the new motors im finding have different shaft sizes. Read a post that said they have changed the nema 34 shaft size? trying to avoid buying new gearboxes too. the machine will run as is but goes to fault mode if pushed much and isnt user friendly. any help or comments on brands you have had good luck with and suppliers are welcomed. Thank You in advance K
