Hi all, Im Philip and 1 am currently building my first CNC router. I feel like i know a lot of people on here already from reading various posts etc. Mechanically im nearly there however, Im having a few problems deciding on the electrics. So far they consist of a 800 x 600 x 250 steel enclosure which is empty at the minute! I am using slaved axis for Y. Y is 3m long and is driven by 2 damen cnc rack and pinion anti backlash unit with a 5:1 gearbox. X is 1400mm wide and is driven by a 25mm ballscrew with 10mm pitch. Z is 200mm and is driven by a 25mm ball screw with a 5mm pitch. I am planning to use this router in my furniture business , so i would like a controller that is robust and reliable. I have done a lot of research but i still feel like ill be jumping in and end up wasting time and money. I was looking at the 10amp 4 axis kit with 8MN steppers from benezan for example. Then i thought maybe closed loop. Whatever i use i would like it to be fairly straight forward to wire. Any advice or observations would be appreciated.
Thanks Philip

Hi,
I realise i was a little vague with my first post. As this was my first time to post i didnt want to be to specify or seem demanding. Anyway on the electrics front i had some clear ideas but no.1 would like to know if anyone else has tryed this. No 2 has anyone had any bad experiences with any of the components.
Option 1.
Cs Labs CSMIO/IP-M
Leadshine ES-M23480 (8NM) Motors
Leadshine DS-808 Closed loop drivers
Linear power supply.
Heres where im unsure
My machine is 4 axis and i emailed Cslabs about the IP/M and they said use the IP/S. In my head if i have the IP/M with a closed loop system then technically my gantry should be locked together has it should be impossible to lose steps?? Am i completely wrong in this assumption. If anyone has any opinions no matter how negative i would appreciate them , as i would like to get some parts ordered soon.
I should probably mention i already have the IP/M , it was bought a while ago for a different project, but i would like to use it if at all possible.
Thanks Philip

With the IP/M whilst I think you technically can slave I think it's a bit of a fudge around but I'm not 100% on this....jazz will better advise you (I've got an IP/M but am using one stepper and belt for my x axis) when he comes along...

Thanks Neil,
Still a little unsure which way to go. Was looking at the IP/S but i think i would go with an open loop system if i bought this due to budget restrictions! I could always sell the IP/M to offset some of the cost. I had a look through your build log , thats an impressive looking Control box! I think when i eventually get all electrical parts on the bench i will be using some information from your log if you dont mind.
Thanks Philip
