Thread: Fingers crossed it'll cut ally
Mark list all your inputs and how you are using currently using them.
off the top of my head..... mach setup is saying iv 4 inputs i can use... that would have been fine if i didnt have the slaved x axis
i need one for E-stop two for Z home one for Y home and one for Z home
i know there are other exotic ways of running switches parrallel/series etc but i woul like my "home" away from the extream edeges of my machine so i can easily keep an eye on lost steps
im assuming another port will give me another 9 inputs ???? cant remember,,,, my brain is melting :)
Not true guys? if you want compatibility out of a cheap card they say go for one using 'NetMos' driver chips onboard. I bought a second card that cost less than a tenner and it works with EMC2 fine and others have reported this chip to work well with Mach3 also. I used the details here http://wiki.linuxcnc.org/cgi-bin/emcinfo.pl?NetMos to help me decide which card to buy and Linux picked it up no problem. You have to specify the address in the config file and it was this guy off Ebay i got the card i used from http://myworld.ebay.co.uk/fullspeedit.If the nagging gets really bad......Get a bigger shed:naughty:
Doh just realised i was replying to the previous page on this thread. Oh wellIf the nagging gets really bad......Get a bigger shed:naughty:
Hi Mark just read ball the thread,very interesting I use a 650kv outrunnnermotor on a mill with a 80 amp speed controller, servo tester and a 15volt psu supplly. I have run it on mach3 to cut some small bearing pockets taking a 1mm cut with a 6mm cutter Ihave not had any problems with heat build up. I have fitted a fan on top of the speed controller bolted to the main frame of the mill.
28-11-2010 #137Hi Mark just read all the thread
i dont have any heat trouble with the larger two motors, its the tiny 4000kv spindle thats giving the bearings im using a hard time m250cnc(phil) thinks it may help if i run them in bit by bit not alowing them to over heat or trying lighter grease, ill give those a try when i find the time
thank god somone has a rc brushless motor spindle working for them, loads of people seem to have a go at building them but iv had no reports of any useful results untill yours, are you running it 1:1 or are you on pullys and belts??
Hi Mark I use a Arceuro ER16 which is 1:1, the motor is actualy a 800kv have loaded a photo
Splendid!!! 1000w (ish) ??
i might need to fit a fan to my esc, it gets to hot to touch now and again
are you not finding the 800kv a bit quick to cut aluminium?
I use good quality aluminium and spray a small amount of WD40 to lubricate.
