Hi, always fun to read about others projects. Dont know if I posted pictures on my encloser before? I am very happy with it and I dont want an open solution again. Sorry for the bad quality on the pictures https://i95.photobucket.com/albums/l152/madelenlindstrom/Jimmen/Orac-2.jpg https://i95.photobu...

I have the same problem, also need one. Alt. anyone know what i could use instead? /Jim Hello Does anyone have one of these units going spare? I'm looking at an Orac for a friend that has been part retrofitted. The Parajust spindle drive is there, but the choke is missing. If anyone has one they wis...

I have one just standing beside the ORAC. Built me a bether one.
Dont know how much its worth. Dont know the shipping, I´m in Sweden

Hi,
after my mach3 conversion the spindle became much weaker on my ORAC.
I dont have a cable like this. Can this be why?
Ive ordered a new 1hp inverter and motor, but untill I got this up and running it would be whery nice to fix the old.
Pictures where things are connected would help alot.

Hi,
Anyone know whats the name/modell of the blt between motor and spindle? I need to buy a new one.

In case it helps, attached are a few pictures to match yours of the Denford-fitted VC-150 that was on my Senior 3C CNC mill (which I suspect is a slightly earlier edition of yours - my VC-150 is QC dated 1987 which ties in with my mill's 1987 date of manufacture). But my lathe is dated 1985, so min...

Hi, One word of caution if the inverter has been out of use for some time - old electrolytics can let go if they are powered up again after a long dormant spell - they can either just leak/ooze; or they can rupture in dramatic style. The new ABB inverter/VFD I fitted to my mill came with oodles of c...

Hi,
I found a paper label today, it was located ontop of one of the capacitors



So it should be a vc130? And max 1,3kW?
/Jim

Thanks for the manual The cover on my vfd is missing so I took pictures on the numbers I found. The top picture have the pin on 1,5kW, but I dont want to by an 2hp motor until Im sure. https://i95.photobucket.com/albums/l152/madelenlindstrom/Jimmen/DSC00712.jpg https://i95.photobucket.com/albums/l15...

Anyone?

Hi, I retrofitted my orac -85 last year and it works fine with mach3. But I experience the spindle to be very weak now, and because the spindle stops and the z continue the top fuse on the (original) power supply burns. I cant findd how many A the fuse should be. My questions are, if annyone else ha...

Hi,
I ´m almost finished with converting my ORAC. Only the turret is´nt finished. If you have questions I might help you. And cjmerlin here on the forum (he is also on the machsupport forum) helped me alot, so if you ask him he might help you too.

Hi, I dont have my multimeter here today, but The inputs are on the other side of the transformer. They are red, white and green/yellow. And 240v

Hi, I Made a big misstake when I disassembled my ORAC. I was sure that I didn't need this part, the PC1601 its the "rectifier board" for 24v and 12v. But now I know bether. =) From my transformer I have two green cables, two yellow, one blue, one orange and on black. Could it be possible it should b...

Thanks for all help

Hi, I think the plug has 8 pins. If I only could find the electrical schematic PC1965 maybe I could figure it out with the colours on the cables. The resistors I bought for my geckos are 0,6w is this OK? And about the step motors I e-mailed Cetronic and got this answer: Parallel connection mode as f...

Hi, Ive decided to use Geckodrives "G210" for my ORAC. But is there anyone who can tell me you're setup? The settings for the microstep? All info are appreciated. One more thing I need to know is the connections on the turret. On drawing "S2124" there is 5 cables but is this right? thought there whe...
