I'm going to be selling my BP I R-ram with Acroloop control. From day one it has been a headache of massive proportions. It needs an entire rebuild from top to botom. The head gear selection is loose to the Hi/Low lever which can be anywhere and engage hi or low. The engagement moves all around. The air brake lever from the cylinder to the brake knob is broke and a replacement (along with the adapter) are impossible to find. The Aussi draw bar can't be installed because finding a drawbar for the bridgeport that works with the aussie seems also impossible to find.
The ball screws are wore out and need either rebuilding or replacing. The nut yoke must be loose on the Y axis as I get a ridge of at least .015 when it changes direction while contouring. The ways are worn (out) and as they are chrome, I shudder at the cost of remachining them. Grind the chrome off, then hard chrome, then grind to size and scrape the chrome....
The control is great... when it works. It has a problem with seeing drives to load programs. Hit load program and tell it drive A: and it don't see the programs. Use library and it sees the programs. Play for a half hour to several hours turning off the machine and rebooting, going into save and delete protocals without saving and deleting and like magic A: will finaly appear. You'd think that solved the problem, but no, now it CAN'T see C: drive to load but it can see what is on it with the library key.
The Frequency drive works really great half the time. The rest of the time it comes up with "under voltage" even while reading balanced three phase of 232, 235, 235. When this hapens the spindle shudders with a pulsating force and turns slowly. You can stop it with your hand and it just pulses feebly.
I found a 1989 Supermax with Anilam Crusader-M controls that has maybe 1,000 hours on it. The paint, ways, control buttons and all areas that show wear with use still look factory fresh. It has a new monitor and spindle switch. I'm taking a loan on my life ins. cash equity and picking it up next week. What I can do with a working CNC really put a smile on my face and I haven't smiled in a long t ime. Well not like that. Why some people are such low life scum that they will lie to a deaf paraplegic and show off a machine in such a fashion to hide all of its flaws really threw me. For some reason I had assumed the world would toss me a break due to my circumstances and instead it showed me how naive I was. It just makes it easier for the scum to shake down a mark.
I'm jazzed about the Supermax though. Like finding a rare car with low miles just sitting and waiting for ya.
