Wood Router

[Buba b]

So ive been looking at drive options and im thinking about going with digital drivers over the analogue , im thinking digital drivers would be best suited to run my mill and router as there using both ends of the feed rate spectrum and therefore the torque of the steppers. Having seen a video of the noise reduction of the digital over the analogue drives at slow speed i think its the way to go as im too use to the smooth operation of the Gecko G540.
I was looking at Zaps 2M880N digital drives with the 68v power supply which i was about to buy but the dam voucher code didnt work or the other option is the Kelinginc Digital stepper KL-8070D which would work out the same as Zap with the duty added. Im still trying to find some reviews of digital drives which there dosnt seam to be alot of on the net !.
The only other thing ive got to look for would be the breakout board , which at the moment i know nothing about ?.
Well the sale of the GF didnt go through but shes now in her near finshed kitchen so i can get on with this soon ...... until something else stops me !

Well the rush is on ! my job is going tits up at the speed of light with no new orders coming through the door so i could be joining all the drugged up job dodgers at the job center soon. My lying , cheating , spineless boss didnt pay out on the bounus so im taking my lead from our great goverment and its briliant fiscal policy.

So ive now put in place austerity measures to make sure the router plan balances out. (where have i heard that from !!!! )
I only need a piece of alloy for the Z axis to mount on to finish the router which just leaves the electrics , axis bearings and pulleys to finish. As a result of the austerity plan the digital drivers are out as there twice the price of the PM752,s and in comes a new round of budget tightning to drive me back into prosperity and growth. (where have i heard that from !!!! damit !)

Test fitted the router together and found im 1mm out ! with the gantry being over to one side by 1mm , it dosnt matter but its just annoying and probably the result of me rushing.l



I tracked down the PM752,s on Evilbay for £53 each at cnc-parts4u ( if i want to buy from the UK ).

I had been looking for some info on making a power supply as the £108 price tag of Zaps made me choke abit and low and behold the through the mist came a thread http://www.mycncuk.com/forums/showth...-or-sps705-psu with all the answers from the bickering twins Johnathan and Jazzcnc.
So once ive tracked down a supplier who has the transformer in stock and free post il get building.

Three Zap SY60STH86-3008BF steppers at £90

That leaves just the breakout board which ive still got to check on but a cheap as chips one for £20
Grand total of £329 or just get a cnc-parts4u kit for £364

Im going to start making a power supply and case to fit the drives , hopefully something will come along and i can get my digital drives at some point but time will tell.

Three 3Nm steppers here for £82.19.

What features do you need from the breakout board? Since you're now on a tight budget, if you're not bothered about controlling the spindle and stuff from the computer you don't need a breakout board. The PM752 (or any good cheaper drivers on eBay) are already optically isolated, so the breakout board does not add any more protection for the outputs. It just makes it slightly easier to wire up. Just thought since you're happy to make the PSU you might be happy to consider making a simple breakout board...
